On one of the current affair shows they are going to talk about how ethanol is good and that it has been been aproved to be sold as well. ist on this thursday

does anybody know what the go is with this will it damage your engine or what. I have heard things such as..... that only cars that are built from like this year or last year onwards can handle it well. and that any car older than a year ...welll it will affect it...they were not meant to run on this fuel and that....they werent designed for it and it will damage it ...if the unleaded has ethanol in it.....

any knowledge would be appreciated, has anybody had bad experience with it, they dont plan to label it if it only 5 percent, but they will wen its 10 percent, at the beggining of next year.

yeah since i read this kind of inetresting.

Ethanol isn't the solution to fuel problems.

1. Where do we get the feedstock from? Raping the farming land? I did some rough calcs to illustrate the amount of feedstock that would be required. To substitute only NSW's petroleum products with ethanol would consume all of the Austs sugar cane crop and half our wheat crop.

2. Given the above. Ethanol blends are just a stop gap solution that's generating a lot of media hype. It might buy us some time, but I don't see the point in spending too much time developing the technology if it's ultimately going to be a failure.

3. The engine damage issue is just a small tech problem compared with points 1 and 2.

4. Ethanol has a lot less energy content than petrol. So your fuel consumption goes up and you either refuel twice as often or have to carry twice and much fuel with you.

5. The price cuts they are talking about (ie a few c/l) are pretty much neutralised by the increased fuel consumption. So you're not much better off overall.

6. Don't quote Brazil as a great example of ethanols success. Their farming techniques aren't exactly sustainable.

From what I've heard, Ethanol has a cleaning effect on your engine, which initially sounds great. If you run your car on it FROM NEW it will enjoy a long trouble free life. Unfortunately, if you run a car more than a few months old, the carbon deposits built up from regular petrol use get swept away by the ethanol in big chunks, blocking valves, injectors, fuel lines and damaging pistons etc. So running a used car on Ethanol can cause irreversable damage, running a new car on Ethanol is potentially a good idea. Just what I heard.

I posted this in the forced induction section recently:

from the Federal Chamber of Automotive Industries website

http://www.fcai.com.au/ethanol.php/2004/03/00000001.html

"Nissan vehicles manufactured from 1 January 2004 onwards are capable of operation on ethanol-blended fuels up to E10 (10% ethanol), providing that blending of the ethanol component to the petroleum component of the fuel has been properly made at the fuel refinery (ie there is no "splash-blending" of the fuel).

For Nissan vehicles manufactured prior to 1 January 2004, Nissan Australia does not recommend the use of E10 because of drivability concerns and/or material compatibility issues."

hmmmm.. yeah who knows maybe this was done to make ethanol look good everything else i have read seems to go against this. maybe they are making this 98 ethanol look good with another ingredient in it and then people will say ethanol is good in fuels so it gets introduced.....and then they will just make it crapppy and cheap and take out the ingedient that made it good.

...but by thne it will be too late. it will be at the petrol pumps everywhere.

what i have read seems to be a common trend

ethanol doenst produce as much power as petrol so saving a couple of cents with ethanol wont matter since it wont as long...they just cross each other out...maybe thsi is all been done as a gimmick to make it look like the goverment is doing the right thing by the enviroment.

The major source of ethanol is actually the refinement of sugar cane, at the moment alot if not most of the ethanol produced as a byproduct has minimal use and is wasted. So positive number one, ethanol blends will add to the australian economy, as the sugar industry is currently not really worth jack due to many reasons.

Second positive ethanol actually is a higher RON than petroleum products, i think its about 114 and has much better combustion properties. Although with higher blends there is an increased fuel consumption but we are talking very minimal and with a low blend like E10 you most probably wont even notice it. The reason for this is just a tuning problem same as if you tried to run your car on avgas its not tuned for it therefore cant take advantage of it.

Yes the properties have some down sides though, ethanol may eat so to speak through rubber but again in such low blends as E10 i doubt we will really see this. There are rubbers that are now in use that are inert to these properties, hence the car manufacturers saying the use is accepted. Tthey have been around for a long time though and i am of the opinion the only reason they were not used is cost cutting. Also you have the issue that ethanol will absorb water vapour but seeing though our fuel systems are closed systems i dont see a problem here.

So really ethanol has its ups and downs like everything but in my opinion the ups strongly outway the downs. Sure, the reduction in petrol prices will be small but money in your pocket is money in your pocket right? All i would suggest is like normal you dont pay attention to any of the crap on any current affair programs as they most the time are purely uneducated or biased opinions, just do a bit of research for yourself and decide for yourself what you think.

If you can argue that a few % decreased economy is negligible, then you can argue that a few % lower c/l is also negligible. And therefore the argument that it's cheaper at the pump is null. Hell i'd say even a 10c/l decrease is really SFA, that's what, a whole $6/tank.

I've yet to see anyone show me that ethanol or any other biofuel will provide a significant long term solution. I want someone to put together a sound systems analysis that considers the size of the problem and the size and impact of the solution. Instead everyone seems to be focussing on trivial crap such as fuel line damage and saving 5c/l.

The "but it can be made from a waste product argument" doesn't sit well with me either. Please show me some calcs that outline the quantity of waste product that we have, the volume of fuel that could be obtained and then put this in perspective with the total amount of fuel required. Waste products are waste products for a reason.

The fact is that at the moment there are no significant long term solutions, yes there have been substantial increases in alternative fuel technologies but these are far from a major production stage. Especially if we have people complaingin about power reductions of ethanol there is no way hydogen combustion engines will be widely accepted by the general public. Ethanol is just a band-aid while there is R & D in the area, lets face it petroleum fuels is the major source of energy of the world, once it runs out it runs out. With the addition of bio-fuel or mixes we may prolong this giving us a further time to develop our technologies while at the same time creating a cleaner and more productive fuel.

As for fuel consumtion, the large concern is with carbie engines, a fuel injected engine will have an increase of 2% yes thats 10L/100km to 10.2L/100km and the conversion to the petrol bowser your still going to be coming out ahead at the end of the day. Id rather have $6 extra in my pocket everytime i fill up the money adds, maybe $300+ a year if u fillup once a week.

There are system analysis to show the positive and negative sides to the arguement but the fact is the government releases very few of them but it would be safe to say at the present time australia would already have an easy capacity to produce 200+ million litres of ethanol per year, and this is a more sustainable market than the sugar industry atm, but remember its not only the sugar industry there are many other crops that a simply thrown away as they are not deemed good enough quality for the market. At the end of the day though everybody thinks about themselves consumer will worry about what effect they will see on their car business what will it do to its profit and so on, policy is not always introduced as it is the best thing there are many other factors ($$$$$ lining big business pocket being the big one)

Ethanol is getting quite common in Sweden. And we're happy about it cause we have a lot of forrests that we can make it out of=)

Ethanol is said to give a 30% hp gain, and you will need 20% more fuel. As the ethanol is cheap up here thats a good alternative. 98 octane petrol is about 2 Aud/litre, and the ethanol is 1,25 Aud/litre. Does not fit all engines though.. -But one of my skylines is gonna get fed with it in the near future :wub: We'll see what happens :)

A $300 saving isn't much when you put it in perspective with the $3500+p.a you would be spending on fuel.

but it would be safe to say at the present time australia would already have an easy capacity to produce 200+ million litres of ethanol per year

My rough calcs indicate this would offset less than 1% of NSW's petroleum consumption.

My big concern is that this is a problem with a time scale of 30-50 years and I don't have the confidence that either the govt or businesses are thinking that far ahead. Politicians think in three year terms.

    • Hey everyone, I recently bought myself a 2001 Nissan Stegea M35, and I've had a few issues that I had to fix, my car would start intermittently and I had a bad rocker cover leak, after a couple days of looking I finally found a part number that interchanges with the OEM starter as the OEM starters at $1300 and I can't afford that, this starter was only $270 and I replaced the start and still had the same issues, I posted a video asking for help online and it went very well, some guy said it was probably a bad ignition switch so I took my dash apart and turns out my ignition switch was half screwed in and was loose, once it was tightened it fired right up, I found a local place called "Boost factory" and they sold me a part of OEM Nissan rocker covers, they were $600 which was a shocker but I couldn't find them anywhere else, so I installed them and fixed my oil leak as the old rocker cover was cracked and warped, I now need to replace my boost air inlet hoses as they have some cracks.
    • I am being real ocd and do not want to make amy mistakes so appreciate all help provided. I am overly cautious so asking for opinion even if i know the answer   few questions,   1.re tensioner, should spring be greased lightly?    2.tensioner has two washers , one pressure washer and other has recessed/ seat. I am going to put the recessed one facing tensioner where edges are cut out and pressure washer on top   3. my car has custom triger kit sold few years ago by guy who initially built the engine. I moved the crank gear and it moved in and out easy, only way to remove belt is to slide the crankshaft gear forward which I did. I have seen these being very tough to move , anything to do with my woodruff key?   it has a crank sensor shown in purple which I assume reads from the 12 teeth position mounted to the crankcase gear   4. timing belt doesn’t have arrow stating front or back just a arrow which I think is direction of rotation . Do you agree?   5.i figured out why my crankcase cover was worn as there was no washer installed over the crankcase cover before the harmonic balancer was put in place. It is missing, anyone knows the part number? It looks like this https://justjap.com/products/genuine-nissan-crankshaft-timing-gear-rear-plate-washer-nissan-s13-ca18-a31-r32-rb20-r33-r34-c33-c34-c35-rb25?currency=USD   https://tinypic.host/image/IMG-4535.382Zy2 https://tinypic.host/image/IMG-4537.382dSz https://tinypic.host/image/IMG-4534.382q4U  
    • CTIS (Central Tire Inflation System) has existed since the 80's. I'm looking into buying a Hummer H1 and they generally included it. 
    • My idle is set at 950rpm though - Moving the timing around 20 degrees is not really what I'd call a calm idle. That said... neither is chop, by definition. The LS ECU likes to adjust timing to hold idle as opposed to air. It'd work, but generally speaking there'd be a discrepancy in the base idle and the IACV would want to move the timing around anyway to maintain said idle. I think I'm just going to keep the timing steady anyway. Preserve my engine mounts.  My aircon is now officially regassed. As the guy was reversing I noticed my reverse lights do not operate, along with my reverse cam. This is a bit distressing, because 100% of guides talk about which wire to connect to backup cams as "the goes with the [other color] wire". Often when doing conversions. Unfortunately the R34 colour wires aren't documented Unfortunately I had a T56 Magnum gearbox with it's reverse switch, which also isn't documented. Unfortunately there's definitely not documentation for people with both of these in the one car. Unfortunately I forgot. After many hours of this, I have a reverse cam and reverse lights again. The wire going through the trans tunnel to the reverse switch had broken. Upon inspection, it looks like this one wire had about 7 spade terminals and extensions in it.. for reasons I cannot possibly comprehend. I also spent the 750 hours required to clean up the wiring behind my head unit which now looks like this: This is a monumental improvement relative to what used to be there WRT triple gauges, head unit, traction control, wideband controller, and whatever the f**k OEM stuff still exists there in various states of connectivity/needed. Next step is to check in at the Exhaust shop to see/confirm how much clearance I have, to decide what mid mufflers or 'resonators' (which are just straight through, narrower mufflers) I can add and hopefully cut out a lot of exhaust leaks, pinhole, v-band or otherwise. But first step will be to 'take a look' before the next step.
