Dave

 

i only use shell optimex

 

i use shell optimax in me ERST wouldnt use anything else

 

optimax full stop

 

i use optimax in me cossie only ( and i will just call the AA now instead of using BP )

as for me normaly aspirated cars i use any old unleadded fuel as theres no difference on em IMO

 

optimax in me series 2 tub n V6 ZS sweet

 

Optimax

 

an ST170 should be fine on normal unleaded i'd have thought

 

what does it say in the owners handbook dave_st170, ?

 

Dave ANY normal unleaded fuel is fine.

You WONT see any performance gain buy using optimax/super unleaded because the ST170 has no way of detecting the different type of fuel and making the nessasary timing adjustments, so its a waste of money buying optimax/super unleaded for a std car

Now if you have a bluefin fitted there is a bluefin setting for using optimax/ super unleaded that DOES make a difference to the car because it reprograms the ECU and adjusts the timing for the high ron rating optimax/super unleaded has

I use the cheapest unleaded in my std ST170, which at the moment happens to be shell and sainsbury in my area

HTH

 

Cool.

Thanks guys


Dave
