FYI Relatively clean oil after 5000 miles?

[Joe Hogan]

Interesting I checked the engine oil to day before two month trip. Can still read the hatch marks through the engine oil after approximately 5000 miles. The engine is a 450 hp diesel Cummins.
Granted the engine only has 15k on it, but my experience with diesels I was expecting black nasty stuff. Something to these “clean” Diesels

Yes. And as my buddy boldly told me…
GET YOUR OIL TESTED BEFORE CHANGING IT!

He ran a fleet of trucks and saved a ton of money with a simple $50 AMSOIL sample each year rather than just dumping it for no reason other than the “recommendation”.

I want to start doing that too.

It is on my list to do at Spartan this fall. Got two sample cups from Blackstone Labs. One for the new oil and one for oil to be drained. The new oil test gives a nice base line for future testing.
