Michael. 2312 Report post Posted May 17, 2015 I just noticed this at a pump in the North Shore today. Didn't realise it was available other than at Hampton Downs. Having read up about it there seems to be so much conflicting information on what cars it works with and doesn't due to the age of cars and these so called 'flexi-fuel' cars. Some say it will eat 'regular' cars rubber fuel lines and seals, even lead to bad oiling etc but then others say it doesn't and brings many benefits despite increased consumption. Same with the way cars are tuned, I gather its 110 octane? Clearly most NA cars wouldnt see the advantages of this unless having a higher than normal compression. Curious to know who uses this fuel and for what applications? 1 Quote Share this post Link to post Share on other sites
my_e36 43 Report post Posted May 17, 2015 Some American brand cars sold here are Flexfuel compatible. Dodge and Chrysler in particular. Those ones can use that E85 fuel without issue. You are right in the Ethanol does eat the rubber and seals and causing trouble in non-Flexfuel fuel system. Sent from my iPad using Tapatalk Quote Share this post Link to post Share on other sites
jake1829 119 Report post Posted May 17, 2015 I use the E85 gull force pro fuel when doing track days / weekend fun runs Pros 45+HP and 90+Nm TQ over my 98 map Cooling properties of Ethanol that helps with keeping temps down How angry my car sounds + backfires /flames out of the exhaust Cons Few places in Auckland to get E85 at the pump (Hampton, Puke, Hillcrest) Bugger all mileage Don't run it normally for DD as I am lucky to get 300km out of a 60L tank verus my 550km usually on 98 3 Quote Share this post Link to post Share on other sites

gjm 3191 Report post Posted February 8, 2018 Ethanol is a good fuel. It burns well, and cleanly, and in a car set up to use it, it is superior to unleaded fuel. You do normally use more fuel when running ethanol than you would if using 'conventional' petrol. (There's another discussion about octane levels, energy delivered and heat, but we'll skip that for now.) However, there are many different (synthetic) elastomers that are lumped into the category of "rubber" used in O-rings, seals and hoses. Two of these, most commonly used in motor vehicles, and which do not significantly deteriorate with petrol exposure, are Buna and Viton. Viton is more expensive. Buna can deteriorate with heat while Viton is more resilient. Viton also survives exposure to Ethyl Alcohol, while Buna does not. Care to guess which material was most widely used by the motor industry? Typically, the biggest issue isn't elastomer (rubber) deterioration - it is the cleaning effect of ethanol that causes problems, exacerbated by old hoses which should probably be replaced anyway. These things do have a limited lifespan, after all. Quote Share this post Link to post Share on other sites
Benji335i 21 Report post Posted February 8, 2018 Thanks mate for the explanation. upgrading my LPFP and having an ethanol sensor and analyser installed with new lines from the tank to the HPFP. i ideally wanna do E50 but is it easily purchased?
