Unleaded or Super?

[road2ruin]

Hi guys,
Being new to this game I am after some advice, again. I have a TVR S3 and need to know if there is any benefit from running it on premium unleaded or will regular do just as well? Aslo I have had the car for three weeks and have yet to find out whether the stereo works, havent felt the want to turn it on.

I run super, but to be honest I never see a difference between super and regular, but I have heard some cars dont run well on regular? I run super purely because its better for the engine, which on a car I intend to keep a long time, is important.

Enjoy

I would always use premium unleaded from either BP or Shell. Even though the petrol comes from the same refinery, different manufactures add there additives in afterwards. BP & Shell have a good cleaning chemical that’s does clean the engine plus it ran at a higher octane. I used it on my Endurance bikes and it did make a difference. The best stuff is the racing fuel at Silverstone…

I think the S3C was actually designed for 95 unleaded but several owners reported that it was much happier with 98.

Either 95 or 98 will be OK but you must have the ignition advance set accordingly (ie retarded slightly for 95 compared to 98)

I used to have a daily Honda Accord Type-R and found huge differences in power output when i was 'in the zone' and at high revs. That was the first thing to convince me that Optimax was the way to go.

The second thing was when i had my S2 Unichipped at Austec & the insides of the engine were so coked up with soot from cheap 95 ron fuels that Austec couldnt get the best out of it, I blasted loads of fuel cleaner & flush through the system & went back 500 miles later..... then they got another 10hp out of it from being clean.

I also had it tuned (timing set & chip fuelling done) on Optimax so now it performs so well with it, normal unleaded just feels 25hp shy.

I am unhappy at the current cost often being over 100p per litre - but hey ! you pay your money, you take your choice.

By the way there is a new Tesco's fuel available at 99 RON and I beleive BP have a new racing enthusiasts fuel at over 100RON available in London & Milton Keynes at £2.49 a litre. I havnt tried it yet !

I tried the Tesco 99 Ron today - it makes the car run really nicely, i cant say theres any more power than Optimax (97.8) but it likes it.

However i wont use it regularly as it doesnt contain the cleaning agents that Optimax & Ultimate do, IMHO.

mine runs well on the tesco suoper unleaded.... ran a bit lumpy in hot weather on 95

mine won't breath flames on 95 ron or BP ultimate so it has to be Optimax, just to really scare those boy racers who desperately try to keep up in their corsa's.
