Interesting Oil Test

I thought you used you drain oil in your lawnmower AKA KLR

I do. Drain oil from the Triumphs which both get the 20-50 Amsoil. It gets relegated to the lawnmower, rototiller, zero turn and finally, the dirt road.

The KLR gets the 15-40 Rotella T, same as the farm tractors and the cages with the exception of the Powersmoke. It gets 5-40 Rotella Synthetic.

15-40 Rotella is JASO-MA rated even though it's not stated on the container.

The drain oil from the KLR goes bye-bye right away. Because the KLR has a roller and ball bearing lower end, it shears the oil down to a lower viscosity pretty quickly, like 1500 miles between changes.

Put it in, looks like oil. Drain at 1500, looks like water.

It would be nice to include Motul in that test. I have used their oils a lot in race engines and they do very nicely in terms of wear resistance. If a captain come thru the shop and we change oil I usually put in the 5100 in a 10/40.Owners report better gearshifting as an aside.

Nev,
It is looking more and more like Motul 300v 10w-40 and Shell Rotela "Synthetic" 5w-40 will be the other oils included in the test, but Silkolene Pro 4 is running a close third. There are still a few more days for them to make the decision - voting ends late next week.

The oils they are considering:
Redline MC 14w-40
Motul 300v 10w-40
Motul 5100 10w-40
Repsol 4t Racing 10w-40
Shell Rotella T synthetic 5w-40
Shell Advance VSX4 10w-40
Silkolene Pro S 10W-50
Silkolene Comp 4 10W-40
Silkolene Pro 4+ 10w-40
Silkolene Pro 4 15w-50

The Rotella is the only oil I offered to test that is not MC specific, and the low ZDDP levels in the current formulation concern me - it is also the only oil that will not be a true synthetic base stock. But so many run it in bikes, the other forum members are talking me into giving it a run on the dyno.

AmeriLube : American Synthol and Amerilube : synthetic lubricants

I use Amsoil 20W50 and find excellent finger test viscosity and color retention (still slick and fairly clean) at 8k. The clutch or rather shifting begins to become a bit more clunky at 8k. The local Triumph dealer, surprisingly, sells Amsoil off the shelf for nearly $14/qt. I get it directly from Amsoil for a tad less. I too use my drained Amsoil in yard equipment for a season.

The Amerillube 10W50 Eagle G4TC would enable year round protection, for the colder months as well. I'd be interested in the results of this oil in a test up against the better known competition.

Amsoil's white paper: https://www.amsoil.com/lit/g2156.pdf
Page 23 begins the summary and scoring. Amsoil, Motul 300V and Mobil 1 are the top 3 scoring, in order, for SAE 40. Mobil 1 didn't figure into the SAE 50 group and BMW was put in 3rd place.

Interesting, this one is unknown to me and their website doesn't have much info. I will call and talk with them today and report back.

Volatility or flash point for the AmeriLube, if I recall correctly, is not particularly high in the great expanse. Low flash point means carbon buildup. I don't see a great deal of black in Amsoil under 5k. At 8k it's time for a change; before it's won't work in my yard machines.
