100 RON Fuel is recommended to maximise vehicle performance. Does anyone use standard 95 RON and are there any reasons why its use should be avoided?

FLYNN · 17th June 2012, 11:34 AM

Do not use 95 RON on a GTR unless you want det and a big bill. Personally I only used v power and momentum even though the BP garage is closest

Why do You ask anyway?

bones · 17th June 2012, 12:05 PM

But is there a technical reason? There isn't a warning NOT to use 95. It just doesn't maximise performance?

Anders_R35 · 17th June 2012, 12:51 PM

From the user manual:

VR38 engine
Use unleaded premium gasoline with an octane rating of at least 93 AKI (Anti-Knock Index) number (Research octane number 98) to maximize vehicle performance.

If the premium gasoline specified above is not available, you may use unleaded premium gasoline with an octane rating of at least 91 AKI number (Research octane number 96), but you may notice a decrease in performance. Do not use gasoline with an octane rating lower than 91 AKI (Research octane number 96).

Why do you want to know?

Well I think the OP wants to know what if there is no 97,99 at the petrol station. What about the COBB 95 RON map?

I thought it was because you wanted to save money at the petrol station

This will explain a bit about det/knock

Detonation - Cause and Effects

As a rule do not use normal unleaded on a unmapped GTR. If there is no choice, run it off boost

That's interesting. I wonder what the problem is with BP? Texaco also have a premium fuel.

Are those two fuels 99 RON rated?

BP is 97 rated and Texaco is 97 also AFAIK.

Thats good information. Thanks boys.

bones · 17th June 2012, 02:35 PM

Just another thought. If you mix 50/50 100 RON with 98, does that make it 99? And is it ok to mix?
