Remember, just a few ounces per fillup is all they claim ya need. I really doubt a few ounces will mess up injectors on a vehicle that burns oil. In fact, if my truck burned oil I'd still give it a try
. This is the same argument I make about adding it to gas, I added 2.5 oz to 20 gallons. That's hardly a drop in the bucket.
