[QUOTE="Pisshead Pete"] What does it do on the highway? I just checked mine after a tune up and got 11.2l/100kms from the 17 y.o. 350 Chev at legal speeds (which is entirely not indicative of average anything!). [/QUOTE] It gets about 10l/100 kilometres on the highway with the cruise control set at 110 kph, the 42 psi in the tyres may help here also (recommended pressures). Boxer
