What To Use In My R34 25Gt-T

[v8 eater]

sorry if it has been mentioned before i couldnt find it - I even googled it and didnt get anything back..

ive just bought an R34 25GT-T and loving it. However, im not sure if i MUST use 98 octane on it or not.. i had a 300zx which will backfire/misfire (not sure which is the correct term) when using cheap unleaded.. Im not sure what i should be using.. if I must use 98 and used cheap unleaded, why would it be bad? engine problems or just blocked injectors or fuel ignites in exhaust?

thanks in advance

Yes, 98 must be used.

Low octane fuel normally causes detonation/pinging.

I tried to use 95RON unleaded. Generally, no adverse effects should be expected with RB25 NEO on 95RON mechanically. But what I can tell you from personal experience - I did notice a severe power drop, the car felt like 60hp or so hp down on power, lost response and felt lethargic and unpleasant to drive. Worth mentioning also is the fact that fuel consumption went through the roof, something like 20-22litre per 100km of city driving could be observed on 95RON.

if you want to be a tight ass and run 95ron then i advise you sell the car, as this car is not for you.

The Neo ecu is pretty adaptable. When I'm in has I run 95, it always feels a little slower and I keep the boost down just in case

But seriously, if its pretty close to stock then its not gonna explode running 95, it will just run better on 98
