I guess I had a rare problem that oil analysis found early and saved me more troubles down the road. Couple months ago I was getting 2.5% fuel in oil with a short 2,000 mile run on the oil. All injectors were tested to be just fine. As it turns out I had an internal seal in the Cp3 starting to take a hike. Truck ran perfect and you would never have known! Replaced Cp3 and oil analysis just came back less than 1%.

 

That is good news!!

 

Worth the money. Dust, fuel, coolant, all sorts of problems can be evident early.

 

Who does your testing ?
