Chris, I agree with you about the use of Esso Supreme 99+ as an insurance against ethanol damaging some of the older cars. I am not sure about the use of fuels in a QP V and as you have discovered the manufacturers and dealers do not want to make any statements that may give rise to later claims for damage. It may cost more but most of the older cars have a low annual mileage and so the cost is bearable at present. I still use TetraBOOST in my Indy (1972) and am considering adding it to the fuel in my 1990 Biturbo 222E where it is supposed to counteract for up to 15% ethanol. Neither of which has a catalytic converter. The lead content in TetraBoost would kill a catalyst in the QP V.

Cheers – Keith
