Any interest in oil test of AmsOil at 12,800 miles

I run AmsOil in my bikes. They state that I can double the manufacturer's stated oil change interval. I have their 10W-40 oil in right now. I was thinking of getting two test kits if there is a good bit of interest. One for the engine oil and one for the rear drive oil. This would test the oil in real life conditions as you guys know where I rode these miles... if you followed Adventuresbyguy.com! No more opinions or conjecture. I would post the results here.
If not a lot of interest then I will just drain and replace.
Let me know

I too run amsoil and plan on switching this bike over one it hit 4k so I can be on track for the service intervals in my head. So that's a yes from me.

I’m interested but those tests seem expensive for something so simple, I do wonder how reliable they actually are.
A little history of mine.
Bought a 1997 F250 with a 7.3 diesel engine with 100,000 miles on it back in 2010. Took 4 Gallons of oil every 5,000 miles. I have heard of AmsOil since the 70's as I was a gearhead-car kid. I was looking at their signature oil series. 25,000 mile change intervals. If I could make it to 12,500 I would break even on cost. Discussing this with an engineer at work. He said he had a jeep that he switched to AmsOil as his commute was over an hr and he was piling up the miles. He bought a test kit every oil change. He tested the old oil so he had a baseline. Then as he didn't trust the Amsoil yet he changed oil at 7,000 miles, 10,000 miles, 12,000, 15,000, 17,000, 20,000, 25,000. He graphed it out and he said his graph looked like a water fall then it flat lined way way down in the numbers. He was graphing nickel, copper, and other metals. Wear products for bearings and engine. He couldn't believe how the numbers dropped. So I ordered my AmsOil. I didn't graph it but had it tested at 7, 10, 12, 15,000. Result... oil still good. Continue to use. That was good enough for me! I did get comments back that there were high level of this or that in my oil. But I had written down that I was burning a 50/50 mixture of used vegetable oil and used transmission fluid for fuel. So they said that makes sense. Continue to use oil.
I went on a trip with my CBR 1100XX Super Black Bird out west. Did around 6,000 miles in 9 days. Total of 10,000 miles on oil. Was curious so I got it tested. Came back. High level of gas in oil. One of the probable causes was a lot of wide open throttle use. Hmmm, ok that makes sense as I was doing a lot of miles at 100 to 105 mph on cruise control. Not much in Eastern Colorado, Utah, AZ or NM and western OK, KS. I checked my Fuel Pressure Regulator to see if the diagram had cracked. Nope... just a lot of WOT time. So to me it's like getting a blood test. It can tell you if things are going bad. I trust them!

I don't know how you'd test the reliability of an oil sample analysis unless you sent samples to two different labs, and even if one disagreed with the other, you still wouldn't know which one was more accurate than the other.

Blackstone Laboratories seemed to have a really good, consistent reputation among the auto and motorcycle communities, so I went with them when I did an analysis at almost 90,000 miles. I don't use Amsoil; in fact, I've used multiple different oils including Rotella and the house brand from O'Reilly Auto. If you want to see what one of their reports look like, I posted it here:

Engine Oil will be in the mail today. I just dumped the rear differential oil when I read it was supposed to be changed every 16,000 miles and it only had 13,000 on it. It did come out looking cleaner than the 2 previous drains. I am suspicious of the 1st drain as it was iridescent due to metal flakes in it. Maybe the first ever drain??? My 2nd drain was only about 1200 miles later. I drained out the organic oil and it was somewhat dirty but I think it was due to flushing out the really dirty 1st drain. The AmsOil looked much better after 13,000. We will see on the next drain in 16,000 miles. Engine oil was way overdue at 13,000. I for some reason thought that the change interval was every 6,000 not 4,000. That one I am curious about... although it will be contaminated with the original organic oil.

Ok, got the results back from oil analysis. Now of these 13,000 miles I was loaded heavy and doing a significant amount of them doing 70 to 80 mph getting across the plains there and back and also in BC or cranking the throttle going up curvy mountain roads. So the fuel dilution is interesting. I have another test kit and I will use it at 8,000 miles as AmsOil states that I can double what the manufacturer interval is and we will see what those results are. Especially as I don't expect to be using the bike the same way. (Not loaded as heavily)
I am also wondering if getting the bike flashed contributed to the fuel dilution.
Before winter sets in I may get 1,000 to 1,500 miles on this oil. So this is looking like a long term project on this thread. Stay tuned!

The fuel dilution is interesting. Did you experience any oil consumption in that interval? I found some on a similarly loaded ride, but at a much shorter interval. For my current annual riding pattern, I'm still doing one oil change per year (4k to 5k each year). That trip was the only time I saw noticeable oil consumption between intervals.

I haven't looked into a Blackstone analysis, so have no idea about fuel dilution or other wear. Not too worried about it given my current OCIs.

We’ll try a different oil and test. at the very least return to a normal interval. That extended thing is not working out. Oil changes are cheap compared to engines. Have seen a bunch lately from Hondas 1.5 having this problem. The forum is a rich source of valuable knowledge. Rotella at 3 to 4K interval seems to yield good results. Remember your oil is doing 3 jobs. Clutch, trans, and engine, My Harley could go longer but it had 3 separate oil chambers, Being air cooled I kept it below 5k.

why run the test if you are not going to believe the results. There are two things outside the norm. Your oil and the interval. If it’s a cost thing you can change your oil twice it will cost you the same given the price of your oil.

every time I do a big trip I push things to 4 or 5 k. I know I have just from the missed shifts to 2nd that go away after an oil change.

I know what my oil is doing. I also know oil is cheap compared to engines. I also like to know. I quite changing oil every 3,000 miles long ago. I understand what they are telling me and I also know I went way to long on the interval too. That's one reason I wanted to get it analyzed. Now I will go to 8,000. I won't wear my engine out going to there once and checking. That's 5,000 less miles. We will see what those results are and I will adjust accordingly. I also have 5 bikes so changing oil does add up a bit. So if it is safe to go to 8,000 as AmsOil says I can then I will as I won't be changing oil when it doesn't need to be changed. I used to change oil every fall on all my bikes. About 3 yrs ago I quit doing that and I go by miles now as my winter down time is usually around 3 to 4 months only then out I go. Where did I say I didn't believe the results? If I gave that impression then I apologize. I do believe...
I do understand where you're coming from and your concerns.
Thanks.

No oil consumption as I filled up the 4 empty quarts. We will see what's up at 8,000.
TG - 4 quarts of oil in your engine: really ? If I convert this to liters i get 4.546 liters the manual reads (either 3.3/3.4 liters when you do an oil change and 4 liters if you tare the engine down and rebuild it) can you please confirm that I have read this right ?

Also if that's the case isn't this dangerous for your engine, cant you be creating too much pressure within the engine case ?
