You haven't changed the oil between 345k and 390k ?? If so, why so much mileage between a change?
What gave you that idea? I change my oil every 5-8k.

I thought so. I saw this and misunderstood thinking it was between oil changes.

" By the way, did I read that correctly? Over 345,000 miles? Love it!

That was 2 years ago, 390,780 now."

To find out how healthy the engine is and whether we can extend the oil change. Afterall, the whole 3k mile oil change interval is a myth. No one says that's when you should change oil. At that pace you may as well change it every day. It's no better or worse for the engine.

How are you guys turning that PDF from Blackstone labs into a jpeg? I feel dumb asking but idk how to post mine.

Easiest is to just screen shot it in MAC OSX or print to jpg in WIN

Fleets use Blackstone to change oil when needed, not just on schedule. I think most private owners just confirm their interval is reasonable

This is the most reasonable engine oil thread I have ever read. Lol

I purchased my DD with 189,000 miles, switched to synthetic after I serviced the PCV at 191,000 and now have 333,548. Have done 2 Blackstone oil samples, about to do a third.

My engine has never been opened and developed a leak which I have not fixed at about 300,000.

Look up Print screen in google and how it works.

In Win7 and up there is a Snipping Tool, too... (about the only useful feature in Windows - but that just MHO)

Snipping tool worked great, thanks! I wouldn't be able to fit everything if I did print screen, I fear.

Snipping tool may work miracles, just watch your fingers at all times

Dont run near windows with the snipping tool??

This is the most reasonable engine oil thread I have ever read. Lol

This might be the ONLY reasonable engine oil thread I have ever read...

I don't know, that claim seems unreasonable.
