I do not agree with the whole of the above statement - sorry but...if you want the truck to respond like a civic you go right ahead and enjoy your 87 octane.
Exactly!been using 87 since i bought the truck.... no knocking, no bad acceleration, etc.
Cobalt SS actually requires premium. :devil:Knock sensors: They detect DETONATION then RETARD TIMING.
That means in order for them to do their job and protect the motor from bad gas, you have to do damage to your engine FIRST. If you can't afford gas, stop posing and get a Cobalt.
:yeah:I've ran a few tanks through my truck with 93 octane but mostly use 87. I didnt notice a bit more power or throttle response and damn sure didnt get any better gas mileage...but if you want to buy more expensive gas...more power to ya...
maybe if your pulling a heavy load the high octane would be better so you wouldnt get detonation...but for everyday driving...running 93 is crazy for our trucks
