The Triumph Dolomite Club - Discussion Forum

Tescos,and Shell,are the only super unleaded that my Sprint is happy on.It will run on ordinary crap,but tends to run slightly hotter and run on after a long run.If I get stuck,I have a supply of avgas for the racebike.Mine does around 25mpg round the doors,and about 40 mpg on a longrun at about 70-80mph(with overdrive).

I think RON says 97 for BP.

1997 TVR Chimaera 450

As I remember, even the cam'ed engine with twin choke 45s ran fine on general Super (when ASDA sold it) and or 4 star, after 5 star disappeared. I don't think I was using any Super Plus till Optimax, what V Power used to be called, came out.

The only problems, and they were big'uns, have come from running the Sprint engine on 2 star. Though I did have a similar problem once running a 2-stroke Villiers 2T engined DMW Dolomite with double the oil in the fuel. But killing that shiece of pit was a mercy.
