Witch kind of Injector Cleaner you guys are using? is it safe ?

 

The best stuff to use is Techron by Chevron. The stuff works. Yes it is safe, been using it for years

 

Absolute best cleaner.

Pour 8 ounces of Marvel Mystery Oil into your gas. Clean as can be.

 

BG 44K fuel injector cleaner, baring that BG C5 carbon fighter, or BG MI 3000 fuel injector cleaner. They are all BG products and are very serious on the chemical table. The 44K is the nastyiest stuff you can put in you tank. I ran 3 cans in a row through my old cavalier with bout 100,000 miles on the engine. Ended up taking the head off for a coolent leak, the chambers, valves, and pistons where all mirror clean. Dont think you can buy it just anywhere either, as far as I know its only really avalabile through a dealership.
