Here are the results from a 400,000 mile oil change: http://www.amsoil.com/lit/g1343.pdf?zo=1181889 .

Tim, can you please provide real data like component measurements, filter change intervals, make up oil, oil analysis tests and history, qualifications of the "independent" engine rater, whether or not Haywood Gray is an AMSOIL dealer. The sales literature you posted is nice...but lacks are real data.

The brochure did list oil analysis for lead (30ppm) and iron (150ppm) at 409,000 miles. The Certified Engine Rater worked for Lubrizol. He noted that 95% of the crosshatching was still present in the cylinder walls.

In 2005 he reports he currently has his filters changed and oil analysis at 50,000 miles. His current truck has 519,000 mile on one oil change.

I see that a Haywood Gray is listed as a current AMSOIL Dealer. But since just a dealer I don't see that he sells much. Probably too much seat time in his truck and motorcycle.

This brochure may have the component measurements you are looking for: http://www.amsoil.com/lit/g2578.pdf?zo=1181889 .

Here is deposit and wear data on 60,000 mile oil changes in New York taxi cabs. http://www.worldsbestoil.ca/taxi-test.php .

Here is one with oil analysis and wear measurements: http://www.amsoil.com/lit/g2695.pdf?zo=1181889 .

Here is a school bus study with used oil analysis: http://www.amsoil.com/performa...unty.aspx?zo=1181889 .

Tim thanks for the other info, but I am more interested in the Mack. As for the oil analysis, did Haywood Gray take it himself and only once at the 409,000 mile mark? Perhaps he took samples at 20,000 mile intervals. I would like to see the trend lines of the TBN, Vis, additive packages, etc. Did he top up the oil level between filter changes effectively sweetening the additive package? Did Haywood supply the information to AMSOIL or did AMSOIL run a controlled test on that particular truck. Did the Engine rater take actual measurements that are published, or did he just "eyeball" it. My main area of curiousity is the TBN and Soot due to the dirty nature of the Mack engine. The flyer is a nice piece of advertising literature, however, without real data it is anecdotal at best. I've seen the sizzle, now give me the meat and potatoes!

You are welcome John. Sounds like you need to contact Haywood for the used oil analysis. Hopefully I have left enough hints that you can find him. I did read the soot levels were fine. My read in the brochure and other info on the web was that he took regular oil analysis at the time of his 40,000 to 50,000 mile filter changes.

Here are some soot and TBN numbers taken every 20,000 miles over a 125,000 mile oil change. http://www.amsoil.com/lit/g554.pdf?zo=1181889 . Also has more wear and deposit measurements.

How are them meat and potatoes? Getting full yet?

I think the take home message to the original poster is that if your oil analysis came back fine, then your oil has not worn out. Even at over a half million miles on Haywood's oil change.

Thanks Tim, I got the same idea on filter change intervals and regular analysis too. When we do oil analysis on a particular piece of our equipment, we keep a running record and use that to develop trends. I just thought it would be neat to actually see documented oil analysis on that particular engine of Haywoods. The other info is appreciated, but not pertinent to the Mack with 400k oil change. Take care.

You are welcome John. What kind of equipment are you using oil analysis on? Can you share the data?

Tim, we do testing on diesel engines, hydraulics, portable compressors, gearboxes, etc. Most of the analysis is consistent in sample intervals. Limits are used to trigger additional testing (micro patch, etc.) or oil change. The data isn't mine to provide. Take care.
