I predict a sudden upswing in usage of your Group A oils, not unlike the current global shortage of #42 press in jets created by lucky in his one man crusade to re-jet the world's SOHC4's carbs!

That's part of the reason why I didn't list my "preferred" oils in prior messages, as there are many that can serve as well as my choices, provided you do the correct homework.  My "A" list oils are easily found locally, and are pretty safe "bets".

As for #42 jets, I believe that is a bogus recommendation based on the inability to make the accelerator pump work as it should, and creates more carcinogenic hydrocarbons for all to breathe, that would otherwise not be a factor.  Then again, the poisoning of mankind does seem to have been a popular pastime for a good long while.   I guess that until one develops a lung problem, inhaling whatever isn't perceived as a concern.

(Me, survivor of pneumonia, twice, and 2 pulmonary embolisms.  Makes you think twice about taking a breath when to do so produces stabbing severe chest pain.  But still, you don't have an option.)

Happy thoughts!   ;D

I hope I have enough baby seals to squeeze the oil from.

If that fails I will try Mobil Delvac 15w40. It has ZDDP of 1000ppm/liter and wallyworld sells it @ $12 per gallon.
From research I've done, 1000ppm is below minimum. I would add extra ZDDP (in fact I do)
Optimum for out old bikes seems to be around 16~1800ppm so I add 2oz per gallon.
Above 1800ppm is a waste of money and can cause corrosion on some materials (I forget exactly what happens, it was 4~5 yrs ago I really looked into it)
Normal Rotella 15w/40 has about 1200ppm and is JASO MA rated and the best part, it's real cheap compared to just about everything motorcycle specific
I fake being smart pretty good
