Oil Analysis Results - Scotty_imp - 09-23-2021
I thought I'd share a recent Blackstone report sheet. Maybe others would like to do the same on this thread.
I wanted to know how my oil change interval was looking and, while I've read other analysis reports validating the high quality of the motorcycle-specific Mobil 4T, I wanted to see how it was doing in my 4 cylinder beast. Read the report's comments, including the possible longer internal. This oil has been in there for about a year (3,700mi.) and the bike has seen some very high ambient temperatures (105-110F) this summer.

A little hard to read for me, but overall the report properties summary appears favourable.

Thanks Scotty. Am I correct in assuming that most of the contaminants measured are from bearing material? How much did this analysis cost? Are you planning to perform another analysis in the future?

I've used them frequently with my BMW, but my bike being a Honda, I've never thought to send in my bike's oil
The analysis is $30 and they'll send you all the material to collect and send it back to them.

Thanks Scotty for the findings. Here's an enlargement for the 95% of us over 50 so it doesn't have to be read to us:

Dang this is interesting. I want to do this on my next oil change. I'm interested because I go out of my way to use the highest quality oil I can find and I see higher revs more often.

Hi, well there's wear material and there's contaminants. Fuel and dirt are the usual contaminants. You can look at those in two places: silicone (dirt) and fuel %.
If silicone is high the first place is to look is the air filtration and then intake leaks.
Wear metals on this sample look really good. Tin is the first layer of your crank bearings, so they're looking good. Alu and iron levels are below average, and as they mentioned, this is still a new engine in terms of wear in.

Yes, Mr. P don't forget that it has 6 gears. Give the poor thing a break!
RE: Oil Analysis Results - Scotty_imp - 09-23-2021
I'm a huge fan of Blackstone analysis. How did I get going on this? My father sends in a sample each oil change for his airplane engine (Continental IO470N), and has for a very long time. A number of years ago the wear trend spiked in iron, and they brought it to his attention. Iron is a crankshaft thing, often, so an astute mechanic pulled off a couple jugs and discovered a crank counterbalancer that was slowly working on an escape plan. It would have never been identified otherwise as it was the retaining disc on the pin that secures it to the crankshaft, behind a circlip! So, a history of samples for a given engine can be the true value.
For us, the money spent can also be saved with intelligent and scientific advice on oil change intervals. Frequent oil changes also introduce unwanted variables into engine life, and I've heard the same regarding air filtration. Simply removing and replacing an air filter can unknowingly introduce/release more particulate than would have ever been ingested leaving it alone (until necessary). Something to think about huh?
I'm also an 80 Series Toyota Land Cruiser nut. I'm on my fifth. They have one, and only one, Achilles heel: the original head gasket. It was a materials construction thing combined with a very long iron straight 6 block bolted to a relatively high performance, long aluminum head. Anyway, an oil analysis is the smartest repurchase inspection on any used vehicle IMO. Particularly if it's known to have HG issues. Potassium and other coolant indicators are readily picked up, even if it's weeping very slightly. So when I buy an 80 Series I know exactly where I stand on how soon I'll being doing a top end!

I use 6th gear all the time! Just not when I need powah.
