Can I Use 91 Ron In A Stock R33?

[Jez33]

Hi guys, im just wondering as the title says if i can run my car on normal unleaded. I have heard a lot about increased risk of detonation and things, and a lot of people tell me better safe than sorry. but im still at school and im struggling to afford to fill her up, so how necessary is it?

Sorry if this has been discussed before

Any experience with problems asociated with running stock cars on normal unleaded would be appreciated, my car is a r33 gts25t completely stock

cheers

Generally, the higher the octane level, the lower the chance of detonation. Detonation damages your engine internals. Your car WILL run on 91 octane, but it's not smart to do so. If you HAVE to run the car on 91, then keep it below 5000rpm and lay off the boost.

The difference is only 10c per litre... Thats only like $6-7 per tank... Buy "home brand" bread and milk instead and give your car some decent juice man

The quality of fuel in Japan is higher than here too. Australian premium fuel is pretty much comparable to standard fuel in Japan from what i understand. That means that our standard fuel is definitely not sufficient to run a 'performance' car built in Japan, and designed for Japanese fuel.

Hope this helps..

Id stick with the good juice...98 only....but each to their own

If you do run 91RON, I wouldn't be hitting boost at all. Unless of course you can afford a rebuild....

I use 91 RON fuel....always have...with never an issue to speak of......

.......in my 1996 Briggs and Stratton mower.

lol

the factory spec's say 95 at minimum. any less any you could hurt your engine a lot, and your pockets even more. invest in good fuel and stick with it.

If you can't afford an extra $5 a tank sell it.

Read this question again, and think about the Correct answer. no point being deconstructive.

used 91 ron once because it said on the fuel filler cap "unleaded petrol" - i dont knwo about you, but my car didnt really like it...so I used half of it, then put 98 ron.

Would it be alright to run 91 for weekdays and then fill up with 98 for the weekends? As in use the 91 for daily(no boosting) and 98 when you want to give it a trash? I would assume it'll be fine aslong as you keep it off boost.

Yes it would be alright. It would be totally fine to put inferior petrol in your car. Nothing bad will happen. There you go, is that the answer you were looking for?

[Baconer]

think of it this way, your saving money by going cheap on petrol and causing damage to your engine. As someone said your only saving about $6-7 per tank and when your engine dies you will have to shell out 50x more then you have saved so far on petrol on an engine rebuild.

Dont be stingey

Seeing that we're on the topic of what type of petrol to use, what would happen if we were to put diesel fuel into our cars?

You would rip a hole in the fabric of space/time

Actually we're all using diesel (yes, all of us). You get about twice as much torque than unleaded. We didnt want to tell you cos we thought it would blow your mind.

Actually your car will knock even more because the octane level is reduced... The oil in the fuel would probably accumulate in the valves, and screw your cat converter. The engine would definitely overheat and crap itself eventually.

I use Jet A-1 in my skyline.. I get fewer funny looks when I'm cruising at low altitude.

These engines aren't designed to run 91 octane fuel. It would probably cost you more $$$ in poor fuel economy than the added cost of getting 98 octane stuff in the first place.

If you shop at Coles, you can get the discount vouchers to buy Optimax. Woolies/Safeway, you can get Caltex Vortex 95 octane (worst case). Shell probably have a 95 as well.
