hello
i need some help
can i put euro unleaded fuel in my sierra cosworth sapp 2wd

 

Yes, but if there is any doubt about the fuel quality just take it easy.
Ie if the car has been mapped on say shell v power in uk then going abroad(hols etc) and using another unleaded won't do harm so long as it's not foot down all the time, just drive sensibly.
All cossie can use unleaded as std, but ignition may need adjusting, there are some wires that can be joined to effect this change on the std ecu.

thanks
but is it also possible with oct 95

 

TBH I always run mine on Unleaded and so 95 octane, I do occasionly put SUL in but don't see what all the hype is about as I never noticed any difference.

The 2WD when new run on Leaded, although the seats etc are hardened, so can run on Unleaded as well, but in any car when doing so as said your supposted to retard the timing by a couple of degrees IIRC (Again as said there are two connectors one for diagnostics and the other for minor timing trimming in the loom)

It depends if it's been mapped for SUL or not, if so take it easy when you use unleaded.
