Optimax in a cinq

is it just me or is this stuff a load of arse?

i filled my cinq up with Optimax (which cost me about 8 quid more than it would with normal petrol) and noticed no difference in acceleration .. all that i did notice is that a full tank lasted me 3 days trips to work and back where as a full tank of normal unleaded has seen me for just shy of 2 weeks (where i eventually ran out at a set of lights...)

optimax hates cinqs

Re: Optimax in a cinq

A higher octane petrol wouldn't do any good in a small and simply designed engine. I believe I read it was designed with VVTI in mind?

Re: Optimax in a cinq

the haynes manual for the cinq states that "these cars do not benifit from a high octane fuel" not sure which bit i read it in but i remember reading it, now regret spending the extra in the yellow 'un lol

eight quid more a tank? It's about 10p more a litre than Supermarket unleaded, so 3.50 extra - max - a tank full. Optimax may offer slightly smoother running, but not really a noticeable power gain. I seem to get 3-4 mpg more on Optimax so I'd suggest you may have problems elsewhere.

Re: Optimax in a cinq

well i get superb mpg on standard unleaded from total heh... my fave garage... a normal tank takes about 22 quid to fill my cinq up .. took about 29-30 to fill this tank up... but anyway... price doesnt matter heh

running wasnt noticably different... only thing that was different was the mpg.

Re: Optimax in a cinq

my cinq ran no better either when running on optimax and my brothers tuned corsa 1.4 uses the same amont of optimax in half the time it uses the normal unleaded but it did make a very slight difference in take off as it cleans etc.

also cinqs seem to hate (well mine anyway) Nitrox hot shots tried the 7 bottle in my cinq and it mad a very noticeable difference to take of to the extent that i totaly lost the car behind me but only for about 5-10 seconds and ever since using that stuff my engine has never been as good or as fast on pull off or top end it seems to have damaged something but i cant figure out what.

Thumbs up Re: Optimax in a cinq

I run both my punto 1.2 mpi and my UNO Turbo on OPTIMAX and will never go back to standard unleaded unless its a last resort.

Found acceleration slightly improved, especially in the punto and actually seems to last longer- full tank of unleaded would last 7-10 days to and from work, but Optimax lasts 12-14 days ?

Re: Optimax in a cinq

I've used Optimax once, in a fit of extravagance! Not much more expensive in my opinion, and although theres no perceptable increase in performance, the little Sei did seem to accelerate more smoothly. Just remember, the Japanese get higher octane fuel as standard! Doh.

Talking Re: Optimax in a cinq

I use Optimax in my Stilo Abarth and really rate it - it should not harm any car and remember it may take more than just one tank to really feel any benefit. I have also used BP Ultimate but I prefer Optimax I felt the Ultimate didn't give the same smoothness. I've yet to try Optimax in my 1.1 Panda - which is probably closer to a Cinq engine.
