I have had the following issues with running E85 over the last year. This is a daily car so ethanol has never sat in this car.

1. Orings on the injector shrunk and went hard causing a bad fuel leak. So bad that I could smell ethanol really bad pulled over and fuel was squirting across the engine bay. Lucky there was no fire and had to get towed home. Took the injectors out and the oring going into the fuel rail had shrunk a lot and where really hard. As I could just slide in and out easily and no longer an interference fit. Got Scotty to send new orings for ethanol, has solved this problem.

2. Aluminum oxide. This was from the surge tank I used. Did not realise that it was raw alloy inside. This blocked my fuel filter, residue was about 1-2mm thick. Unfortunately the guys that installed this install it before the surge. There for contaminating the whole system. So my solution was to fit two extra fuel filters after my twin 044, and run M2 Upper Cylinder lubricant. As this is designed for this problem with methanol. After running this, my fuel filters no longer have this white residue inside them. So problem solved. I do have a new aeroflow E85 surge to go in just need a hoist, as I don't want other people working on my car any more.

3. This caused my injectors to get blocked also. Had to clean them nearly every two weeks (cost a fortune). Each time they were out upto 40%. Talked to Scotty about this have just order the same cleaning and testing machine he has.

I have to thank Scotty/ Scotty's Customs for his great help. He is an asset to our community and his aftersales support is unbelievable, always willing to help, a real giver!

I you have had any other problems please add so we can all run this great fuel.

Have you seen the new E85 fuel treatment that Nulon just put out? I have no idea if it actually works or is just marketing but maybe it's worth a look for everyone running E85?

Not sure if it would fix or prevent any of the problems from OP but would be interesting to see some people use it and post results

I bought them before there was an Ethenol compatible version when not much was known about them.

People still seem to think running walbro 400s is ok for alcohol based fuels.

I'm telling you it will work for a while, they will die.

Obviously Xing Yi didn't know so it was worth the post

Aeroflow surge alloy anodised inside and out for E85.

just to clear up, the new aeroflow surge tank you havent fitted yet is E85-compatible?

Thanks for all your input, all is appreciated. :rolleyes:

Yes Leroy Peterson, the new aeroflow surge is designed for E85 and was recently released (don't know for sure, auto part guys tend to tell stories).

Also had seen this black gunk stuff before I went E85. I have not personally seen it or had problems with it myself. But more input the better.

I forgot to also add that I was running the Maditive E85 treatment and the lucas oils one too when I had the Alloy oxidation happening. They did not stop the alloy corroding, and were useless for my problems. You can come and get my bottles I have left if you want as they will be going in the bin. M2 Way Better! And have not seen any alloy oxide since.

Black goo comes from the combustion chamber, not the ethanol. Direct injection petrol motors have the same issue, only 10 times worse, as there is nothing cleaning the crap off.

I have seen alloy rails corrode in a similar way, but my raw alloy tank lid hasn't caused any issues yet, 6 years on. Perhaps it's the grade of alloy? Either way I would be anodising every fuel component you can.

Got fresh engine, (i.e so no carbon anywhere) running on E85 for awhile since runin (10,000kms?)

Put a tank or two of 98 in, to satisfy demons in case of evil e85 doing e85y things.

Put E85 back in after sufficient demon-cleansing time

ton of shit in fuel filter and car running lean under boost, thanks, Haltech engine protection!

Knowing exactly 0 about 98/E85's cleansing properties, clearly the combination of the two either causes gunk, or flushes gunk in/out from somewhere, my filter was fine and my AFR's were fine until I put 98 through the car. Funny enough, was fine on 98 also, but obviously less fuel there as less is needed so a partial filter blockage may have had no effect.

    • For these last 7 years of ownership, I've always had to use a small scissor jack under one of the front tow hooks to raise the front just enough so my low-profile jack fits under to reach my subframe jack point. I'm beginning to get annoyed of always having to do this. Are there any lower low-profile jacks that fit under the gtr lip on a dropped car?
    • Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed 
    • hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me
    • Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
