When I got my TSX almost two years ago I used to put in 93 octane, but during Summer 2004, I switched to 89 octane. Gas prices went up and my budget wasn't that high to keep paying for fuel and I travel a lot during the summers, so every penny counts. I haven't noticed any problems with 89. I wouldn't use 87 octane though....-phase- said:i agree..91 octane if i can..but if im low on cash..89 once in a while cant hurt too much right?
what is your fuel consumption figures?Revenent said:I fill up with Chevron Supreme 92 octane... Actually, my TSX hasn't drank anything else.
:nod: :nod:Noel said:When lower or using un-recommended specified octane rating fuel. The ECU will retard ignition timing which prevents detonation and pinging. These 2 will no doubts cause engine damage. Whilst retarded ignition timing also means a reduction in power output, in some extremes up to 25% until when correct octane is re-detected. The ECU will slowly "un-retard" and return to specified performance levels.
I will bet youmoney the owners manual says its okay to use lowr grade gasoline.TSX 'R' US said:oh...and if something goes wrong with your car and the dealership finds that you're using an unrecommended octane gas (so they can blame it on that), your warranty is useless.
