I have a couple injectors that are acting up on my O2 Duramax. I have been for a while and I’ve tried several different additives and nothing made a difference. My truck used to get 17 miles per gallon pretty steady but it was down to about 14.5 until I started using Archoil the first tank. It went up to 17. The second tank was 17 five the third tank was 18.4 and although my truck didn’t seem to run bad before You can tell that it’s running better now.

Difficult to get

Love the product, truck runs great with a noticeably improved mpg, however, having to ship it is super inconvenient and hot shots is sold in stores and is very comparable. If it were as easy to get as hot shots I'd choose arch oil but it's just not convenient.
