cheap or what
cough cough... ;)

btw
original posting on tyresmoke.net :)

have you filled the landy then?? :lol:

Is it a high octane fuel?

Is it a high octane fuel?
yer 102, compared with the normal 95 or the superunleaded 98.
-
you should notice a difference...and not to just your wallet!!
-
kiss good buy to those valves :lol:
-
Audi loves it, but its no where near that high round here.
-
i think it was top gear or 5th gear who did a test
unless you own a performance car which would benefit from higher RON then you wont notice that much difference
we're talking scoobies btw
although if your car is tuned and modified it would notice but your average petrol chugger wont notice
your wallet will though

regular unleaded 92p super 98 ron 94p 12 months ago it was 83p regular 94p 98 ron.........guess which my bandit NOW uses ;)
makes a hell of a difference too...

If an engin has been tuned or was built with a high compression ratio - say 11-1 then it will require higher octane fuel to avoid pre-ignition which would cause vave and piston damage! Performance or race engins running this sort of compression ratio would benefit from 100+ octane. Higher copression would need higher octane or octane boosters. Running a standard road engin (and they are built to run on the standard poor quality fuel sold at todays petrol stations) would not realy benefit from higher octane fuel but would probably appear to run better because of better quality fuel. At best you would gain a cleaner burn and shouldn't have any valve problems. It you want better performance from your fuel, run the recommended grade but use a primium brand, Shell or BP and avoid supermarket brands. To benifit from the extra potential power in higher octane fuel the engin has to be built or tuned to process it efficiently.
I run a 1200 Bandit, Wisco Big bored to 1216, Kent Cams, balanced crank, stage 3 Dyno jetted, blue printed head, dyna 2000 ignition etc.etc and it does 157.8 bhp on std pump fuel Compression is estimated to be 12.5 to 1.

legalise red diesel i say :wink: :lol: :lol: :lol:

What octane rating was the 4-star leaded fuel?

legalise red diesel i say :wink: :lol: :lol: :lol:
you mean its not legal :?:
why do I see all these garages selling it then :?:
thats just asking for trouble
:lol: :lol: :lol: :lol:

I think the old 4 star leaded was about 97/98 octane.The old 5 star leaded was 101 octane.But that went out years ago
-
Most performance and more modern engines that dont use a static map in the ECU will benifit in some form from this. In my case the engine has been rebuilt and its like filling up with rocket fuel.
Its possible in engines that dont get a power gain that you'll get better economy as the ecu senses the changes in exhaust gas content and backs off the mixture.
-
Yes. but mainlybecause most modern pump fuel is [!Expletive Deleted!] compared to what used to be sold 15 - 20 years ago. Modern engins are designed to run on a wide range of fuel qualities. The fuel sold in say Brazile or India won't be the same quality as that sold in say Europe or USA. Yet the cars sold have to run on what comes out of the pump. Use any quality or better grade of fuel and you will get an improvement.

So this would perhaps be good for the classic cars such as the GT6? :?:

Its perfectly legal to use red on the road, as long as you go and pay the required extra fuel duty on top to the customs and excise, or alternatively (not sure if its still legal these days) farmers use to be able to run comercial vehicles/land rovers on red, but with serious restrictions on the amount of road work they did.
