Mobil 1 15w50 vs Mobil 1 15w50 Racing 4T

Motul also recently just updated their Semi Synthetic 4100 series 15W50 to API SP, That is a normal PCMO but also with plenty of ZDDP, +1200ppm, and about half the price of 300V, i used the old SL version a couple of times and liked it.
The specs on the new stuff look good too, -45c pour point for a 15W50 seems impressive, and a 226c flash point, plus a strong TBN of 11.0.

Motorcycle version likely doesn't contain molybdenum in order to be wet-clutch friendly.

@Panda87 is running HPL primary fluid in his 2023 Harley Road Glide. The UOA shows it has 434 ppm of moly.

This analysis was done at the same time as my engine oil analysis in my other post. The oil held up, but there was some form of dirt intrusion going on. I wanted to get HPL’s take on it and got a call from David. He discussed his concern over the amount of silicon in the analysis and recommended I change the fluid to get the contamination out and try to find out where the contamination was coming from. It was super neat getting to discuss this with him! The standard change interval for the Primary is 10k miles. Come to find out, in 2018, HD issued a service bulletin to install a “Primary...

OP,
If you can't get the oil you want M1 15W50, which is a great oil. And you don't want to run a bike oil. There is another Mobil 1 car oil available to you in Europe that is high HTHS and high ZDDP.

M1 10W60 (full synthetic, API SN, ACEA A3/B4)
KV100 = 22.7 cSt
HTHS = 5.7 cP
VI = 178
SA = 1.4 %
TBN = 11.8
Flash Point (D92) = 234 C
ZDDP = 1300 ppm Phos.

Good oil but pricey and not very easily found other than online.
