Just wondering what type of petrol everyone uses and if anyone notices any differance in econemy and/or performance with one type of fuel or another, just curious

if you look in the search area there are many posts about this and people will be able to tell ya what they use...

i jus use whatever premium fuel is available at the garage

shell optimax, all my cars run better and smoother with it and better fuel economy as well.

Short answer is, as little as possible, for first start. Then I switch to LPG, and can actually enjoy the performance without going bankrupt.

LRP, usually its 93 octane, but if i can find it i put 95 octane

i have to run my car on 98 super unleaded i nomaly use BP

Nice one Brian but to be honest if I was that bothered about the amount of fuel the old girl uses I'd have got a 1.4 TDI Polo. I just wondered which fuel made the cars run the sweetest

Mine runs by far the smoothest on LPG, and engine life should be doubled - not really relevent on a M20 of course, as they do 300k + anyway.
LPG consumption is not affected by driving style anything like as much as petrol is. No excuse for not keeping foot hard down!

99 every time.
but i run a lead converter too.

95 Ron shell unleaded only, thats what she's mapped to, and thats what she likes to drink( a lot )

what does LPG stand for?

I use LRP four star in my 318is gives it much better performance.

i only use optimax,especially after the tests 5th gear done that showed a high performance engine gained 14bhp more just by using optimax, i dont even think about economy or mpg.

Most of the time i used leaded 4 star, which is still available if you know where to look. Chuffing expensive at around Ԛ£1.30 a litre, but the car seems to go better and run sweeter with it on the leaded. I don't run my car everyday though, it's very much a second car for me so the difference in cost isn't that much, if it was a daily driver there's no way I could afford it.

Of the 'normal' fuels I've always rated Shell Optimax, it's always made a noticable difference to other cars I've used it in.

95 unleaded but with a bottle per tank full of Millers octane increaser, asused in my supercharged 840, i swear by it

Yep just put a tank of Optimax in mine and it does feel more responsive

We dont have Optimax over here in NI yet (none that i know of anyway) so i usually just use normal unleaded but every 3rd tank i put in super. The car def runs better with super and performance is noticably perkier.

Hope they bring Optimax over here!!!

In europe they call it Shell V-Power, if you've got that then as far as I'm aware it's the same thing

Thanks Stevetigger, just wantede to make sure, we dont get that over here.
cheers

You sure? Never heard from anyone in SA running on LPG, but never heard that it's not available either.
Also known as propane.

V-power is 100RON and is something quite different to Optimax (which is UK only) Its not cheap even on the continent too, last time I went we were paying Ԛ┚¬1.30 a litre in Germany!

I just started using Tescos 99Octane Super, and i DID notice a difference! It was mentioned in one of my driving mags here so i thought i'd try it.... great stuff!

A question for the Tech Guru's but can the cars (e30's) actually automatically map themselves to this high octane fuel (98,99,100 ron)

Becuase if it cant then why pay for it?

I would be surprised if that age of vehicle does much in terms of advancing the ignition to take advantage of the higher octane.

So the slower burn rate will probably lose you power on the standard chip.


Personally, i cant tell the difference between 95 and 97 on mine at all from driving it, neither in economy nor performance.

On a standard or near standard E30 engine, in good condition with clean internals, it's all in the mind.
As long as the RON of the fuel is high enough to prevent "pinking", then a higher RON will give no benefits at all.

Sorry only saw this now
Yep thats right no LPG here in SA, its either LRP, or ULP or Diesel.
We get propane, but no one puts it the cars, the garages dont have the right pumps for it i think.
cheers

i use esso 97 octaine, for some reason i get better miles out of a tank if u use esso fuel.

Sainsbury's 97 octane fuel. Seems alright, MPG is slightly improved plus its not too expensive.

At last someone else who see's sense

I have tried it...It made no difference...ThereÔš's a difference in appreciating nice clothes and food, its tangiable, you can see, feel and taste what your paying the extra for.

Running 100RON fuel in a car designed to run on 95RON is giving you the feel good factor because of its marketing,thats all.

RiDE magazine tested these advanced fuels a few months back on a couple of 600cc, 15,000RPM sports bikes, on a dyno, in controlled conditions...The difference compared to "normal fuels"?

ZIP...

So, if a 200BHP per litre sports bike canÔš't benefit, what makes you think an standard E30 can

Its your money, all im saying is a standard road car(unless specified by the manufacturer) doesnÔš't need itԚ…

Some of the rubbish people write about these fuels(and chips) makes me laugh, ive heard people say that after filling up with 99RON they had the traction control light on everywhere

Pleeeeeeeaaaaaaassssseeeeeeeeeee!

Is this a good thing?

I heard somewhere that supermarket fuels lacked the detergent component and should not be used all the time

Load of bolox...

How much carbon deposit do you think a fuel is going to "clean" off a 15+ year old engine...You'd struggle with a scraper..

I run my Hayabusa and E34 on tesco's standard unleaded , there designed to run on 95RON and do so quite happily...If it runs rough or has lost some smoothness it needs a service not a fuel change!

makes no difference to my car so cheapest stuff available for me! not paying shit loads extra Ԛ£ for f*ck all extra power.

I always put 95 in my car before it went bang as there are no sensors to detect the difference. I might try some 98 or 99 when its back on the road and see what happens except for the extra dent in the wallet.

Isn't BP 97?



If youre buying 95 then it shouldn't matter where you buy it. All the petrol stations in the same area will probably get their petrol from the same refinery.
