The problem is that I have a European specification car with the following engine: capacity: 1781cc stroke: 86.4mm bore: 81mm compression: 10.0 which produces 82kw at 5500rpm and 157Nm at 3100rpm. According to the book, it requires 98 RON (Research Octane Number indicating anti knock properties of the petrol) Premium petrol. What car is it? The car has been modified slightly to meet the DOT safety requirements but *NOT* the EPA emissions (since I was immigrating at the time), so the engine is unchanged (no catalytic converter etc.). Three "solutions" have been suggested to me:- 1) Mix regular leaded and super unleaded in egual proportions. 2) Use octane boosters. 3) Use racing (114 octane) fuel! Any suggestions as to which is the best &/or the most cost-effective solution? Shamim Pirzada AT&T Bell Labs research!ssp (201) 582 5354
