Shell Optimax Extreme 100 Ron

[ruffryder]

The fuel is now available in australia and i am very excited! But it contains 5% ethanol in it. Will this be ok with our skylines? What are your views on this?

[Wink]

100RON will give more power.

However, this is only if your ECU is tuned for the 5% Ethanol otherwise it will run lean.

Consesus is:

It's good if you can program your ECU but the small number of stations that carry the fuel (at this point in time) makes it not worth it to use it.

I just tanked up some for the track day tomorrow.

I think i still had about 15L of optimax in the tank .... so we will see how we go tomorrow. if it doesnt like it, i will just add more fuel or reduce timing

Put 40 litres in today and after a while i done some testing. My knock has reduced at least 20/30% which is great as a safety feature. Seems to be going quite strong as per usual but if it picked up a few kw's it would be hard to pick, but i will definately will be using it more for the reduced knock

Well guys, even though i used about 1.5 tanks worth of petrol today, I could definitely notice the reduced knock levels, a result of the 100ron fuel.

Id be happy to use it often, but its a pain finding a petrol station that stocks it. Most of them are about a 10 minute drive away, at least

Guys, not sure about this but does the 5% ethanol do damage to the skylines?

After reading the posts, it seems that Optimax 100 will make engine run leaner. Since my Skyline is currently running rich (usual symptoms such as soot on rear bar, poor fuel economy, etc), will Optimax 100 naturally cure the engine from running rich? You opinions appreciated

I have heard that a lot of car manufacturers, including Nissan, strongly recommend not to use any fuels with ethonol, as it corrodes the engine.
