Pep Boys was selling 5-40 diesel synth for half price because nobody was buying it.

I burn diesel spec'ed synthetic oil in my motorcycles. If I could get Rotella in a 5w20 or 30 I would use it in my Yaris. 40 is just a bit too viscous, but maybe not.

What motorcycles are those? Mine calls for 10-40 which has been going for half price at Pep Boys because no one is buying it they want 5-30, 0-20 etc/

I have a Kwawsaki KLR, which is a 650cc single and a Triumph Bonneville, which is a 900cc twin. 10w40 is fine for both, but the additive package in the CJ-4 oils is superior (IMHO) than anything found in S oils.
