i recently bought a mint series two and the guy handed me a castrol lead additive and octane boost mix stylee thing and said to use it with normal unleaded cause its meant to run on 4star? is this right? will i fuck sumthin if i use normal unleaded without it? or is it better to use optimax or sumthing? any comments thoughts or advice would me much appreciated!

 

you should use Shell V power(new name for optimax} or at least super unleaded which has a higher octane rating. do you know when was the last time the car had a decent set up was?

 

optimax, ultimate or any of the super unleadeds really mate- i've bin told they don't like normal unleaded so i've never tried.
stick to the premium jobbies and she shud be fine- no need fot the extra, expensive additives mate

 

so will it be sound if i just blast some o that in? without the additive? is that what yous do? no idea when the car was last set up but it think it needs it, its got a flat spot just before 4000rpm?

 

Hi mate. Any Super grade unleaded will do. I like V power (Optimax) as it's quite cheap. No need for addative.

A setup is defo a good idea. If your in Scotland, goto AVA.

 

iv seen a couple people mention AVA, where are they?

 

yea any super unleaded should be good enough, 97 ron is lowest you should use. i put normal unleaded in once, the car ran like a bag of nails and resulted in a injection system rebuild . . .

V power is good

 

I must ask, will car have better oiling (valves...) if I put lead adittives in fuel? and maybe go better? because now I putting in car fuel (in may country) caled "eurosuper 98" or 100 octane. wizh no lead in it.

 

I just use normal unleaded when i had the car set up the guy asked what fuel i have been using i told him and he said its fine never had a prob with it

Fooked if i am paying the price of super unleaded for a every day car would cost us a bomb

if you use 95 unleaded you will have to retard the timing and lose power that would be around 115 bhp on a standard rst

the more its tuned the more power you will lose

 

Its mean if I use 98 with led that I will have more power?

isnt thrue that lead is only good for engine (for oiling) ?

 

97 super unleaded means 97 octane its still unleaded more octane you have the more boost or ignition advance you can have = more power

 

yes, and if I put lead adittives in fuel (98 octane) will I have more power? I mean will I feel liiitle power

 

not really leads just there to lubicate the valve guides and cool the valve seats not really anything to do with power

there as not been a cvh engine thats been damaged by not using leaded petrol or a lead adittive

 

ok thanks

 

AVA are near Glasgow airport mate

 

AND OF COURSE THERE ARE THOSE WHO'D TAKE LIZ HURLEY TO THEIR
LOCAL MACDONALDS INSTEAD OF A POSH RESTAURANT AND WONDER
WHY THEY DIDN'T GET A NOSH AT THE END OF THE EVENING.....


COME ON GUY'S YOU'VE BOUGHT A PERFORMANCE VEHICLE
THEY NEED LOOKING AFTER AND MONEY SPENDING ON THEM!

 

much more is super to normal unleaded?6p?8p at most
so if you fill a 50 litre tank its costing you £4 more to get super than normal,thats me taking it to 8p of a difference think its only 5p up here so thats only £2.50 of a difference for better/safer/cleaner fuel
not really a ball buster after all

 

ok I want say that I bought lead adittives before few hours and put it in tank. and dont feel any diference. just that

but 3 pound for 250 litres of fuel is good price for little engine protection , but maybe unneccesarry.

 

Dont bother with additives, no big power boys use it. just fill up with super unleaded, service it with good plugs and oil and get it set up regularly, end of!

 

get sum super unleded 98 ron stuff and put sum NOS octain booster in thear should bring the octain rating up to about 103 ron the higher the ron rating the beter the burn rezalting in more power and a smother engine also it cleans the injection lines out and the valve faces. shame we carnt get the fule from japan they have 105 ron out thear

 

I do look after it and if it run's fine on unleaded why would i need to put super unleaded in it

We use the car every day and do at least 1 tank of fuel a week min so work that out over a year and it adds up like i said the car has run fine on unleaded for nearly a year now with no prob's

Each to there own at the end of the day

In my country we have unleaded 100. and I hear that this things like octan booster cooling fuel, and that is reason for better going.

 

In my country we have unleaded 99 or new formula V-power that it is better know´n as. But the 98 unleaded does the job

but how much is it pr liter in the UK?

her it is 10,56 kroner for the 95 unleaded, about 0.8£
