Thank you for everyone's input & comments this a great forum & I am glad I could contribute, hopefully I can keep it interesting.
Update: I did have a lengthy conversation w/ Dave @ Red Line today. GREAT GREAT customer service & I am not even a customer yet! He actually felt the oil held up really well considering the heavy fuel dilution and agreed the wear numbers looked good in such an extreme environment. He agreed with my strategy of running another race simulation on Mystik 15w50 w/ the corrected limiter protocol and gearing. Then sample again. I was blown away, most companies would recommend their product as a cure much less say a competitor oil held up well. I told him we would do that w/ the Mystik & then run another identical race simulation using Redline RACING 40wt (15w40), which is what he recommended for our application. Both samples will be sent to Dave and will share them on here as well. Right now we are in a holding pattern b/c of COVID19 and the track is closed but the owner said he will let me know when we can get back to it. As a side note I also race two Yamaha R1's which we will be running the same sampling program & I will make sure to post as well in a separate thread. As for everyones input plz see my responses below:
Nice UOA. The viscosity loss might be a combo of shear and 2% fuel dilution. I'd say the oil is doing just fine except you are WAY off of Mystic's specs. You could try the M1, 15W-50 or 10W-40 racing 4t or similar Amsoil product and see if the shear changes. As both the Amsoil and M1 motorcycle oils are among the most shear resistant of oils in those viscosity ranges. The Amsoil 10W-40 being a little more viscous at 100c @ 14.2 vs 13.4 for the M1.
The M1 15W-50 is fairly shear resistant in MC use. It also has a great HTHS viscosity at 150c of 4.5 or so. And 18 cSt at 100c.
Mystic publishes info for the 15W-50 of 19.5 cSt at 100c. You are way off of that.
Oh, and how about a few pics of the bike!!!
I'm an old guy who, due to health problems, can't ride anymore. But my idea of heaven is populated with big-bore dirt bikes! My last bike was a KTM 380EXC, and it was down on power...
Cujet thank you & I will look into a hosting site for pics to be uploaded. Shes a neat little machine w/ quite a bit of work into her.
I would be curious to see how T4 Rotella 15w40 would fare in comparison. Surely it would hold its own in 4 hours.
Kris we feel the Mystik has a more robust additive package & that is why we ran it. Rotella is great oil just felt in this application the Mystik held the edge. Our biggest issue right now is excessive fuel
a race only machine needs racing oil, + of course Redline comes to mind to protect your investment. you can call + get recommendations from one of their techs.
Ben you are correct sir & we do have experience w/ both Motorex & Motul. The results were not worth the price point of the oil considering that our change interval is every race and or practice. However that being said if things do not improve we will sample Redline while continuing to run short OCI's.
Redline oil and sprocket changes
He's way off of the published viscosity numbers because it has a flashpoint of 350 due to the fuel dilution. That's no fault of the oil. He outlined why the fuel content was so high.
Nothing wrong with running a synthetic oil, but this UOA shows great wear numbers. My feeling is why would he need to run a synthetic to protect his investment?
Bonz, we agree 100%. Fuel is our biggest problem.
The engine is defiantly high out put. Frequent oil changes are probably a good thing considering its use.
CT8 its getting ready to be even higher. We have built a 2nd motor w/ the head decked, ported & polished. Cam & valves. Funny thing we learned at the National, we were probably a good 10hp from the rest of the field in the pro class.
