Hi all,

Im new to the forum so bare with me..

Basically i need some advice; Over the weekend i filled up my car with contaminated fuel from a servo in melbournes south east suburbs ( sorry cant give names for legal reasons ). The fuel is a high octane ethanol blend and up until now has performed great in my car.. But this time as soon as i started the car it was running rough and once i left the servo i noticed a significant loss in power and then the engine began to misfire and stall and my engine light came on. i immediately parked my car and got a mate to pick me up...( at this stage i just thought it was a fault with my car!) while driving home with my mate, he needed fuel and filled up AT THE SAME PUMP! as soon as we took off, same faults.. engine light, misfires, loss of power.

I have taken fuel samples from both cars and the fuel is yellowish colour with 2 distinct layers which dont blend with each other. (see photos )

http://img16.imagesh...atedfuel001.jpg

The fuel also has a sweet smell ( like ethanol ) which is fair enough because it is an ethanol blend? But ethanol should be soluble with ULP??? I also thought the contaminate could be water or some form of oil however i have tested both substances and they are both flamable. The top layer produces an oily black smoke and the bottom layer has a very clean burn..

I have taken both samples to the servo and filled out some crappy generic complaint form.. They have closed down the pumps and have had there head office come and check the fuel ( though they havnt given me a response yet ).

Does anyone no what this could be and what potential damage it could do to mine or my mates car (R32 GST-T & 03 Subaru Liberty ) So i can go back to the servo with an argument and rough repair costs etc..

Has anyone else had this problem, id love to know what the fuel companies response was??

thanks guys!

Those images look really dodgy.

I mean I'm a pharmacist - not an industrial chemist; and even I know that there shouldn't be 2 immiscible layers there at all! WTF!

Immiscible means 2 liquids that won't mix with one another.

This has to be followed through to the 'n'th degree.

Feel sorry for you & your car; mate's too. There'll be other complaints too. Someone's head needs to be :P

Looks like the whole fuel system will need to be cleaned out IMHO with pump & filter replaced & that's a MINIMUM.

I'd get an NRMA (or equiv.) report too with their free legal team backup. NRMA (or equiv.) will have an occasional service centre if you're close.

Keep receipts so that when the fuel is analysed, THEY PAY!

Cheers for the help guys...

Id imagine it wouldn't have done much damage as ive only driven the car about 5km since filling it. But ur right Terry, there should never be seperate substances in fuel.. which is why im worried about just cleaning out the fuel system and running it again. If that contaminant is something corrosive or silicon based it may stay lodged in the cylinder, clog up the valves, blow by the rings... any number of catastrophic possibilities!

ive called ACCC and there about as helpful as a brick..basically said the fuel comp may pay for the repairs or they may not.. and if they dont you could take them to court but it may be a drawn out process..

Might give RACV a call and get them out to diagnose the fault. a document stating the fuel is the cause would back me up a bit.

worst comes to worst ill advertise the company thats selling it .. hmm maybe even a call to today tonight.. they love this sh*t lol

ill keep you posted

cheers

Hey Rusty can you please PM me the details of the place where you filled up.

Thanks

Hey mate, im really worried about naming the company in case it comes back to bite me later.. this may go to court so i need all the defense i can get.. id PM u you but coz im new i hav to have 10 posts before i can do it..? dunno y? but ne way...

lets just say, be very weary of any fuel from service stations in the patterson lakes area.. ( that should be generic enough :P) )

cheers

if you are worried about fuel sitting in the motor, disconnect the CAS and turn the motor over. this should empty out most of the fuel out of the cylinders (there wouldn't be much to start with.

thanks mad082, thats a good idea! ill do that tonight!

cheers mate

at my old work we had a couple of cars come in with missfires and when i took fuel samples it had the same thing like an oil ressidue at the bottem of the sample. to get rid of it all you will have to pull the tank out and clean it pull the injectors out and get them cleaned and pour sum injector cleaner into the fuel lines and blow them through with an air gun 2 clean the oil out and change the fuel filter. the fuel they filled up with was e10 from a servo that had opened up the week b4.

Yeah thats possibly what this could be.. e10! i did a simple test last night using a measuring cup; had 50ml of water in it and marked the level, then added 50ml of the fuel to it. As ethanol blends with water, the water level will increase and the fuel will stay on the top as a seperate layer. This gives a rough idea of how much ethanol is in the mix.. well from this test it looked like close to 80% ethanol.

I know its a crude test and theres probably alot of variables... but interesting none the less?

Stupid answer but,

Could it be diesel ? It's yellow in colour

Hmm quite wierd. I was thinking along the lines of diesel also but did'nt want to seem silly either. : b Im sure you would never punish your car like that...

I work with aviation fuels on a daily basis and dont deal with ULP much. From the images though it seems that there is definatly an additive that has separated within the fuel. What that is? Who knows without testing it in a lab. Its hard to tell from the image but it could be contaminated with water. Most of the time water is separated from the fuel and will always sink to the bottom, however it can become entrained, therefore not visible with the naked eye. The servo "should" be doing daily checks for water, but they may have blown it off.

Id confirm that they have tested it for water first. If not get hold of a shell water detector test/or similar and test for water. Eliminate that. Thats basically all you can do yourself the rest will need to be done in a lab. I wouldnt put my money on water. This fuel could have been crossloaded with something else and contaminated it, had an incompatable additive added to it or not properly tested for contamination.

Hope this helps and you get your line back on the road. Let me know how it goes. Ive heard of a few similar stories from mates and would like to see how it works out.

Cheers.

think i may have found the answer.... have a read of this, the first problem is "phase Seperation", exactly whats happening with my fuel!

How E10 Can Damage Your Engine

The negative effects of E10 fuel can cause older engines many problems and can damage internal fuel system parts or engine components. Below is a list of what one should expect to encounter at the expense of using ethanol blended fuel:

General E10 Problems

1. Phase separation (P/S) of gasolineWill cause two layers to form - gasoline and alcohol/water. The hygroscopic ability of alcohol will cause a decrease in octane while also causing your engine to run on pure water.

2. Water contamination (W/C) of gasolineAs previously states, the ability of alcohol to attract water will cause gasoline tophase separate and form two distinct layers. This is more prevalent in marine engines, but can also occur in automobiles that are seldom used or driven in high humidity areas. Remember: engines aren't meant to be used with water.

3. Decreased fuel efficiency and mpgAlcohol gives off less energy during the combustion process, meaning that more alcohol must be used than gasoline to drivethe same distance. E10 fuel can decrease fuel efficiency by up to 20% given the application.

4. Vapor lock or fuel starvationVapor lock refers to when water is attracted into the fuel tank, causing the gasoline to phase separate and the water layer is sent to the engine. An internal combustion engine is not meant to run off of water, therefore causing serious damage to the internal parts.

5. Decrease in octane Because alcohol attracts water, the two separate from the gasoline and cause the octane to decrease from the fuel.

6. Decreased shelf life of gasolineAt optimal conditions, the shelf life of conventional gasoline is only 90 days. However, due to ethanol's ability to attract water and phase separate, the shelf life of gasoline is now drastically reduced to around 1-2 weeks in automobiles and even less in marine or vented engines.

7. Decreased life cycle of parts and engineEven though conventional gasoline is also a solvent, the extreme solvency of alcohol causes unnecessary wear on internal fuel system parts. Up to around 2003, most auto and marine manufacturers did not create internal fuel system parts with the intention of running E10, therefore older engines are hurt the most by the use of E10. Even now many newer vehicles are having issues running E10.

Parts Damage and Engine Damage

1. Wear and damage of internal engine partsBecause of the chemistry of alcohol (i.e. it combusts at a higher temperature than gasoline), there have been some cases where spark plugs, pistons, and even the main engine blocks have been damaged by the use of E10.

2. Damage to metal, rubber, and plastic parts of fuel systemAlcohol's high solvency causes many internal fuel system parts to deteriorate faster than normal and may even fail under normal operating conditions. Recently, manufacturers have been using more durable parts in order to combat the solvency of ethanol.

3. Corrosion of metal parts in fuel system and engineThe ability of ethanol to attract water can cause corrosion of metal parts in the fuel system, also affecting drivability and engine performance even more.

4. Oxygen sensor damageOlder vehicles were not designed to run on such oxygen-rich fuel, thus causing many oxygen sensor problems during the emissions process. Expect to replace these fairly soon after the switch to E10.

5. Carburetor/fuel filter damage, including cloggingE10 causes all the gunk and garbage inside the fuel tank to become free, flowing through the fuel system and clogging the bottlenecks. In fact, ethanol is the same thing as many carburetor/fuel injector cleaners that claim to give better performance.

6. Clogging and plugging of fuel injectorsSee above. Be wary of fuel injector cleaners that contain alcohol, since ethanol does the same job for free.

7. Destruction of certain fiberglass fuel tanksSome fiberglass fuel tanks (mainly in marine engines) were not designed to hold alcohol. The fiberglass coating may break loose and literally destroy the engine.

E10 Drivability Issues

1. Engine performance problems and lack of acceleration

2. Hard starting and operating difficulty

3. Stalling, especially at low speeds

From what I've read I'm assuming it's Shell V power ( The 100 octane one, I may be wrong though!) as it's the only high octane e10 blend that I know of.

And that's the reason I only run BP ultimate.

I really hope everything works out though mate and the servo pays for any repairs to both your cars.

new update..

the fuel company has now declared liability, saying the fuel is severely contaminated with water.

They are sending out a private assessor to look at the damage to my car... then the insurance company will arrange to pick up my car and pay for the repairs!

so hopefully this will be all over and done with soon and i can get back on the road!!

But keep in mind guys, this problem is not isolated to independent service stations or ethanol blend fuels.. this is a problem that can effect any service station from any supplier.

According to this fuel company its somewhat common.. all it takes is a poorly fitted cover, alot of rain or a crack in the tank to cause water contamination like this?

Personally i will never use anything other than premium 98 from the big suppliers in future. A lesson well learned i think!!!

cheers for all the help guys.. ill let you know the outcome

    • The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.
    • And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R
    • So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1680, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
    • Also, I logged some data from the ECU for each session (mostly oil pressures and various temps, but also speed, revs etc, can't believe I forgot accelerator position). The Ecutek data loads nicely to datazap, I got good data from sessions 2, 3 and 4: https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-2?log=0&data=7 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-3?log=0&data=6 https://datazap.me/u/duncanhandleyhgeconsultingcomau/250813-wakefield-session-4?log=0&data=6 Each session is cut into 3 files but loaded together, you can change between them in the top left. As the test sessions are mostly about the car, not me, I basically start by checking the oil pressure (good, or at least consistent all day). These have an electrically controlled oil pump which targets 25psi(!) at low load and 50 at high. I'm running a much thicker oil than recommended by nissan (they said 0w20, I'm running 10w40) so its a little higher. The main thing is that it doesn't drop too far, eg in the long left hand fish hook, or under brakes so I know I'm not getting oil surge. Good start. Then Oil and Coolant temp, plus intercooler and intake temps, like this: Keeping in mind ambient was about 5o at session 2, I'd say the oil temp is good. The coolant temp as OK but a big worry for hot days (it was getting to 110 back in Feb when it was 35o) so I need to keep addressing that. The water to air intercooler is working totally backwards where we get 5o air in the intake, squish/warm it in the turbos (unknown temp) then run it through the intercoolers which are say 65o max in this case, then the result is 20o air into the engine......the day was too atypical to draw a conclusion on that I think, in the united states of freedom they do a lot of upsizing the intercooler and heat exchanger cores to get those temps down but they were OK this time. The other interesting (but not concerning) part for me was the turbo speed vs boost graph: I circled an example from the main straight. With the tune boost peaks at around 18psi but it deliberately drops to about 14psi at redline because the turbos are tiny - they choke at high revs and just create more heat than power if you run them hard all the way. But you can also see the turbo speed at the same time; it raises from about 180,000rpm to 210,000rpm which the boost falls....imagine the turbine speed if they held 18psi to redline. The wastegates are electrically controlled so there is a heap of logic about boost target, actual boost, delta etc etc but it all seems to work well
    • hahah when youtube subscribers are faster than my updates here. Yes some vid from the day is up, here:  Note that as with all track day videos it is boring watching after the bloopers at the start.  The off was a genuine surprise to me, I've literally done a thousand laps around the place and I've never had instability there; basically it rolled into oversteer, slipped, gripped and spat me out. On the way off I mowed down one of the instructor's cones and it sat there all day looking at me with accusing cone eyes as I drove past. 1:13:20 was my fastest lap, and it was in the second session, 3rd lap.  It (or me!) got slower throughout the day as it got hotter.
