98 RON _ URGENT

[The Maive]

Just taken delivery of my Cup and was wondering where the hell do I get 98 RON fuel for, just been to Tesco and its all 95. Whats the difference? Can I get away with 95 for a tank or does it have to be 98? Why 98 I thought that was for Motorbikes, I did know some scooby drivers ran theres on 98?

Help.

Renault recommends Ron 98, Ron 95 will do but the cup will take a different ignition (due to retarding by the knocking sensor) So try to get 98. Ohterwise buy 95 and put octane boost 100 in it, expensive but drives ok.



cheers

It works on 95 but the engine runs rather ruff in my opinion. It uses 98 because of the ignition (rather wild cams) and you should in the futur use 98.

renault recommend 98ron but state 95ron is fine if thats all what is avaliable.

even normal super unleaded is 97RON.

I think BP Ultimate is 97.6 and Optimax is 98.

Stick to useing Shell Optimax 98Ron.......in 2 and a half years Ive only filled up once with 95RON and the car felt a lot slower!

Never use supermarket petrol they dont have any protective additives in them and in a high power car that spells big bills in the future!!

if you ever rechip your car make SURE your fuel is octane 98 !!!

Just find a Shell Garage and park next to the Optimax pump.

Ours idles rough on 95. Put it in in desperation a couple of times and the car just doesnt like it.

Is it worth me driving 6 miles each time to my nearest Shell then everyone?

Tank came full for which there is half left not sure if this was 98 or 95? Can I refill now even if it is possibly 95 or can I just top up now with 98. It may already be 98.

And thanks for everyones input.

put in what you like it doesnt matter if you mix them togethor.

My CRX Mk1 used to hate 95 RON fuel, spluttered, felt flat, no power. Id go 98 everytime, unless you are desparate, in which case just put in enough to get you to a shell garage / BP.

Use shell optimax mate!!

 

[CUP80Y]

Use optimax when you get a chance, but 97 ron superplus, or BP ultimate are perfectlt good enough performance wise. Never use normal unleaded 95 ron cause the performance difference is very noticable.

its like 3 bhp and 3ft or torque you lose out on apparently... which sounds low but you WILL notice it. 97+RON fule needed. Shell, BP and (i think) Sainsburys all have 97+ fuel. You can mix the two types, but it will take longer to filter the crappy fuel out.

Personally I go 4 the more expensive stuff cos I think the car deserves it, plus it is easily noticed. Try it and see m8 and let us know what you think. I guess it also depends on each individual car and how they respond to fueling.

Texaco superunleaded is 98ron, runs really nicely in my cup!

Optimax - end of story, nothing else will do.

Does 98RON make any difference on Willy/Valver? If the car is chipped would it benefit from Optimax?
