Ethanol fuels. A FYI and a Warning!

[dat2kman]

The common Ethanol blended fuels, as found in many petrol stations, ie, E10 blend,

along with the more exotic "race" type blends, eg E85,

are not all that kind to our older cars,

Have a read,,,,

they are not kind to 90% of cars when talking about E85.

 

Usually a whole fuel system requires converting when wanting to run e85, you need larger injectors capable to run usually 25-35% more fuel delivery, you need to replace all the fuel line as the ethanol perishes regular fuel hose.

 

That and its i believe hygroscopic, so leave it over time in the tank and it will absorb water from the environment. So you need to be re filling a full tank weekly or so.

 

Ive considered converting the S15 to run a flex sensor with a Haltec, so i can run both fuels on the fly, but i have a million other things to pay for.

Yes, correct, on e85

The article/link is mainly concerning the very commonly available at most petrol stations e10 fuel.

For newer cars like CroS13 said you just have to change your fuel system. im running E85 on my daily (FG XR6T) had the full upgraded fuel system new lines, 1000cc injectors, new in tank pump and a 2.4Lt surge tank. I love the economy averaging 23.4Lt Per 100km haha.

 

After every couple of tanks i swap it back to 98 and havent had a drama yet.

 

but given that link it will at least clean every nook and cranny with the E85 through her. its like any thing. if its done properly you wont have a drama.
