The Correct Fuel

[nightfighter_r33]

Hi, recently bought a N/A r33. Didn't come with an owners manual.

Just wondering if its ok to run the car with standard unleaded (91 Octane) or will this damage the car?

Filled it with premium (98 Octane) the first few fills and it drank a tank in less than 3 days, and i don't drive like a maniac at high revs either.

Its drinking the standard unleaded much more slowly which is good for the everyday driving i do and cheaper, but i just wanna know if this is ok for the car?

Thanks Justin

Your car is built for a higher octane (100?). I would use at least 95

E10 is good, its cheap and should hold off those nasty noises - until you start winding up the timing that is. Even better, E85

Do a search for fuel consumption, plenty on here about possible causes i.e. sensors, filters etc.

I would use only high octane, but I'm not sure if this applies to N/A skizzas as well.

I wouldn't be running E85 on a stock car, thats for sure.

I'm also wary of E10 given that it eats rubber lines etc.

How many KM's did you get out of the tank?

Rather than changing your fuel you might be able to make the most of it making sure your AFM, o2 sensors, plugs, coilpacks are all in good condition.

Japan has better fuel then we do here in AUS.

I would use at least 95 RON or stick to 98 RON (For turbo car, it is a MUST).

BP all the way! If not Mobil.

one of my mates used 91 octane fuel on his skyline and the engine went bang later. higher octane fuel reduces the chances of detonation which is why i only use BP Ultimate 98RON( WA doesnt have Shell optimax grrr ) more expensive fuel but better than expensive repairs.

its an NA guys...

[Crackfox]

I read somewhere that NA skylines were able to run on regular japanese fuel while the turbocharged versions ran on premium. Im pretty sure regular japanese fuel is 89 AKI which equates to around 94 octane so maybe try 95 octane? Keep in mind I know next to nothing about skylines so this may not be true

[Mayuri Krab]

The basic rule of thumb is any RON 95 for N/A & any RON 98 for Turbo.

I use Vortex 98 on my car.

[R33_NICK]

if i had an import N/A, i'll still use 98RON: safer and if tuning, more power i guess

[Johnny]

its true, if i had an NA; id tune it for 98oct so more ignition timing etc but i guess the stocker ecu would keep the tune safe for 95octane fuel if there are no mods etc.

[mad082]

technically you shouldn't get any real difference in economy from regular to premium. the ecu reads how much air is going into the engine and puts in the set amount of fuel for that afm voltage and tps position. other things will affect economy much greater than the type of fuel. you don't just take into account what revs you are doing, but how far you push the accelerator down. someone flooring it but only reving to 3000rpm will use more fuel than someone who revs to 4000rpm but uses half the throttle percentage. also the O2 sensor controls the fuel economy at light throttle loads, so if that dies your economy goes bad. also if the thermostat is shot and your car takes for ever to come up to operating temp then you will get poor economy as well. or you could simply have a slightly dicky fuel gauge. then there is your driving environment. if you have to stop at traffic lights often then you will get poor economy compared to someone who drove the same trip but got a green light every time.

finally, you said that a tank was lasting you 3 days, but the more important information is: how many kms were you doing in those 3 days, and how many litres are you calling "a tank"? i have used a full tank of fuel in a day, but i also drove 600km on that tank.

agreed, you could say you used 2 tanks in one day - but if u were driving from brisbane to sydney that would be understandable..

so more info pls?

i would however stick to bp ultimate or mobile 8000 buddy

98ftw

to me if you can afford to own an import / modified car, you can afford to put 98 octane fuel in it at least! It just never ceases to piss me off that though the price for unleaded can vary up to 20cpl, ultimate etc hovers around the 1.38-1.45 mark constantly!

[Charles89]

When I had my NA 33, I always put V-Power in it for about 1.5years and I went to sell it, after the buyer has put a deposit down, I just put in cheap normal unleaded.

And straight away, I could notice the difference, the car's responce is so much more laggy.

As for mileage, I find putting 98 in, can get me more k's than normal unleaded.

Like he said, if you can afford modified car u can afford 98 octane fuel

Shell V-Power ftw
