I'm talking days here and not years ;)

The reason i ask is that lately when i get down to below half a tank the car does'nt seem as urgent as it usually does and then when i fill up again (Optimax+NF) its flies again

Now i know i'm not imagining it and temperature conditions don't come into it, so i must be going mad then :D

Scott

yep the men in white coats will be coming for you soon :D
but seriously i know that you get a lot of ****e at the bottom of the tank with diesel so its not a good idea to go to low on a tank.
Maybe you need youre tank cleaning out???.

Cleaning already! its only 9 months old :D

Could i get this done on warranty and would it affect my insurance ;)

petrol does go off esspecially high octane fuel like we all use (optimax)its the additives they put in to raise the actane rating that goes off , but i would not have thought it would go off in the time it would take to use half a tank ?

i fill up around 2-3 times aweek so mine never gets chance to go off :)

Along the same lines as Scott, does NF octane booster "go off"?
I'm asking cos I've a couple of bottles sitting in my garage that I haven't opened in a couple of months? :rolleyes:

Cheers,

Rob.

Soz 4 da thread hijack but does the NF say on the bottle it's CAT friendly also?
Si
PS cant say as i notice optimax going slower 2wards end of tank & i usually fill up ever other week, maybe it's kuz i drive so slow;)

Scott,

Im told it goes off great if you put a match to it.
