depends on the compression of the engine as to what octane to use also. higher compression you need higher octane. Also, if you have carbon buildup on the pistons over time. you'll ping and need higher octane gas, its artificial higher compression. I use BG 44K every 25,000 miles in all the vehicles and that stuff actually removes the carbon.

my uncle did tests on this stuff. used it on a 100,000 mile Nissan motor. pulled the plugs and used a fiber optic camera to see the tops of the pistons. ran 2 tanks of 93 octane and BG 44K in both tanks. all the carbon was gone! you could see the circle imprints and #'s on top of the piston like new!

regular injector cleaner is just snake oil. BG can only be bought at dealers also.
