Oil analysis measures additive levels, wear metals, contaminants (such as water or internal coolant or fuel leaks), soot levels, viscosity, oxidation, and nitration. First, the oil is checked for viscosity loss (thinned out oil) and thermal breakdown (too much heat). We also check for signs of fuel and coolant caused by faulty injectors or leaking head gaskets and we check for nitration that may indicate improper fuel/air mixtures. We can tell all of that from the analysis plus we can detect the early stages of wear on internal parts. Periodic oil analysis enables you to find these problems in the early stages long before real damage occurs.

Quality RV Inspection offers advanced oil analysis, designed to give you data that allows you to tell if your current oil and coolant service intervals are correct. The data will show if you’re changing too soon or if you’re running too long between service intervals. There are (2) reasons why this is so important. First, advanced oil testing gives you the data you need to save money by safely extending service intervals. In fact, some Class-A “Diesel Pusher” (DP) owners are already running up to 25,000 miles between engine oil changes. Secondly, let’s say you purchased a used Class A with an Allison transmission. Advanced testing can show you whether or not you’re running the Allison “long life” approved fluid. If the transmission fluid test shows you’re running an older technology DEXRON-III type transmission fluid, you’ll have the data you need to support changing the fluid over to the long life (Allison TES-295 approved) product and save even more money over the life of your motorhome.
