Re: injector cleaner

Yes. Injector cleaner won't hurt anything. If there are any deposits in the fuel system the cleaner should remove them. You may even want to consider putting a can in every three months just to keep things clean. Another issue that you don't want to forget is to change the fuel filter periodically.

Re: injector cleaner

Do you have any mods? Octane booster? Worthless and a waste of money.

If you use good quality top tier gasoline which has detergents in it you don't need any fuel additives.
