I use 87 and the manual says 87 is recommended. Using any more is a waste of your money UNLESS you're spraying or using forced induction. In those cases the increased pressure = better chance of detonation so if you're using those then go to premium 92/93. -
Generally, 87 octane is just fine. However, if you have a high mileage engine with considerable carbon build up and choose to do nothing about it, then a higher octane fuel would be in order to control detonation or, more properly, pre-ignition. Also, if you have reprogrammed, either Jet or HPP3, it is very advisable to use 91+ octane fuel.2001 Camaro M5 Coupe(1 of 2,737), no options, Whisper Lid, K&N Air Filter, Free Ram Air, MAFS Screen removed, SLP Manual Fan Switch, 160 thermo, DEE\'s T/B Spacer, EGR Block-off plate, IAT resistor, CAI to EGR air feed, B&M Ripper Shifter, SLP Replacement Grill, T/A Exhaust, SLP five spoke take-off wheels, BMR strut-tower brace, BMR Tunnel Brace, BMR 32/21 front & rear sway bars with poly, BMR Poly/Combo Rear Control Arms, Clear front & rear corners, HPP3 modified 87 Octane program.<p><a href=\"http://www.cardomain.com/id/red2k1\" target=\"_blank\">http://www.cardomain.com/id/red2k1</a>Comment
