I get my oil analysis from Mobil Accutrack. The "extended drain" kit also tests for TBN and F-Soot. The kits are something like $18 each and include postage to send the sample in. I attached a small...

As John said, yup, I'm an OM602/603 kinda guy. And when running well, the 60x do generate less soot. My departed OM617 generated noticeably more... roughly 1% per 3000 miles, but it varied a lot each...

Yes, the Delvac is expensive, but at $16/gallon for 4,000 miles... in 10,000 miles, that's $48/gallon. I pay ~$24/gallon for the D-1 and change at 10k, so you're paying twice as much, and spending...

Red Line is about $8-$9 per quart, probably best to purchase locally, due to the relatively high shipping cost. Here's link to the gallons...

I think as long as TBN is not over 12-14, it should be fine, even with ULSD.

And you are correct, Amsoil is now also offering Group III products in the race to the bottom of the quality barrel and...

The soot is secondary as long as the % is under 2%. When it exceeds what the oil can suspend, and the soot starts to fall out of suspension, it can cause significantly increased wear. Finding out...

True. But it does have an impact on extended drains. You can extend the drain interval based on two main limits... amount of soot suspended (until you reach the limit of what the oil can suspend......

That's fine stuff, just don't let it go for more than 3-5kmi... one of the advantages of Group IV/V synthetics is the ability to go 10-20kmi between changes. Dino oil can't deal with the extended...

Hattie, that AFL (http://www.amsoil.com/StoreFront/afl.aspx) stuff has an even lower TBN! The old D-1 was, IIRC, about 12. The new M-1 TDT is 10.7, and I can't find a spec for the new D-1 ESP. But...

I'm not so sure about the higher EGR rates, and soot production, in the newer engines... but I don't have any data to prove it either way. But I would expect far lower soot with the newer...

Yes they are. As are most of the other manufacturers. Any way you slice it, modified dyno oil ain't a true synthetic, and the performance is significantly below the Mobil / Amsoil / Red Line...

Yep, I know it's emissions related. But they're generally pulling additives that our engines like. And I'm not so sure the newer formulas can handle the soot load that our older, indirect-injection...

The problem is, most other synthetics aren't really synthetics, because they use Group III base stocks (basically, hydrocracked dino oil). Very few oils are true synthetics with Group IV/V base...

Say, do you have an URL for Joe's? All I could find is Joe's Sports... didn't look like they'd carry motor oil, though. Any idea if there is a Boise location?

Thumbs down Mobil done it again - changed Delvac-1 and Mobil-1 formulas

I'm reeeeaaaally getting tired of Mobil's monkeying with their product line. The Delvac-1 formula changed... it is now "Delvac-1 ESP", with a CJ-4 rating. Click here...
