Easy Question

[bg11]

Hi guys (and gals)

Just got my hands on a nice R32 GTS-T. Completely as stock etc etc. Am lovin it so far but just have a quick question about fuel.

I have had a look at other topics about it but everyones askin about R33's.

Im not stupid so i gather BPUltimate/98octane fuel is the way to go (i am currently running this anyway)

However... How would using only 95 octane (standard premium, not ultimate) affect my engine. I dont plan on it anytime soon but just curious in case I'm strapped for cash at some point or something. And im not going near basic 91 unleaded. But yeah.

Feel free to driect me to another topic on the same thing (my search skills are somewhat limited as yet .

Thnx in advance

Stick to 98 RON.

Japan and the rest of the world have better fuel then we do in AUS and when you car came to AUS it would have been tuned for 98 RON (I assume).

Stay with BP Ultimate or Mobile 8000.

if you must run it on 95 octane fuel, retard the timing a bit. you will have less power, but it will make it safer on your engine

Ok cheers guys.

It was designed for 95 ron.

Pop your bonnet, look on the label, should say 95.

As long as u dont use regular unleaded you will be fine.

i just saw in the initial post where he said it was stock as a rock, so yeah, 95 should be fine without retarding the timing. i think the standard premium in japan is 96 ron. their standard unleaded is about 90 and their super premium is 100.

Just hijacking a bit...if the car's tuned for 98, but it's available, would 95 combined with a very light right foot work for the time being? Or is the engine going to start detonating regardless?

^^^ 95 will get you around.. just go light foot

[mad082]

also depends on the ECU. if it is the stock ecu then it can be fine to even drive hard (as long as the knock sensors are working properly) as the ecu will knock the timing right back if it detects detonation

[bg11]

So basically I'm cool to run 95 even with a lead foot until I start with the mods?

Also as it is 'stock as a rock' would running 98 for the time being really give me that much difference. I know it cleans the injectors, engine etc and runs nicer... but doesnt normal premium do that to a degree as well?

Cheers

if you can run 98 then do it. even when stock it is best to run as high octane as possible. so don't just run 95 for the sake of saving a few cents if you can afford to run 98

[bg11]

Fair enough. Thanks fellas

Yes. My car is tuned on 98 too.

I was stuck in gympie, didnt have enough fuel to get to the bp, so had to use the matilda=95ron or 91 ron can't remember.

I just had to cruise home on the motorway, nothing went boom, as long as you don't putting crazy amounts of load on the engine you will be fine. My DET didnt go over 15
