Book Bits: Synthetic Oil Solves Turbocharger Problem

From "The Practical Handbook of Machinery Lubrication"

A construction equipment contractor was experiencing premature turbocharger failures when certain engines were operated under full-load conditions and used around the clock. Investigation through oil analysis and diagnosis of the failed components revealed that the failures were caused by coking of the petroleum base oil within the turbocharger oil passages, thus restricting oil flow and resulting in bearing failure.

The initial cause of the oil coking condition was excessive temperatures within the turbocharger housing. A fully synthetic diesel engine oil was selected of the same viscosity as the original petroleum base mineral oil and installed. Premature turbocharger failures did not reoccur and oil temperatures dropped by about eight degrees Fahrenheit.

While we do not run turbo diesels the point is that synthetic oil (any synthetic) provides superior service in high tmeperature applications. For you supercharged guys, you are putting your engines under severe loads and if you don't already run synthetics, this is one more recommendation.

Personally, I was sold on synthetics when I read about how they have less modifiers in them resulting in more of the total oil mass being lubricant, how they flow better when cold and hold viscosity better when hot, and how they are capable of suspending more 'dirt' so that it can get filtered.

The price difference between synthetic and normal oil just isn't enough for me to not run synthetics.

I have been converting my fleet to synthetic oil. :D

I agree...Synthetics :2thumbs: ...good cold flow characteristics on those nasty winter mornings.

Also, whenever I run my Turbo Mustang on the highway, or am into the BOOST a lot, I let it idle for 3-5 minutes to help lower/stabilize the oil & EGT temperatures before turning off the engine.
