The Stovebolt Site Forums The Shop Area Engine Shop Synthetic Oil?

We use jet engines in a fixed industrial application and we almost never change the synthetic oil. I've worked here for 31 years and know of only once or twice that the oil was changed, we do annalysis. The oil is not a one way trip, it does go back to the reservoir many many times. It is not exposed to products of combustion like in a piston engine so it doesn't get dirty any where as bad. We have an oil system that is seperate from the jet that provides its own pressure,cooling and filtering. Dave
