The title pretty much says it all. Does anyone have any sulf ash content numbers for oils rated for spark only?
 
It varies on the formulation but here are SJ numbers for Chevron to compare with the SL of today if that can be found on their website.
Chevron
5/30-.068
10/30 .068
10/40 .068
20/50 .068> Flash Point 500F

30wt 1.03
40wt .085
The straight wt's are PCMO's not HD's

Phillips SL's are all .08 in those wts except they have two 10/30's,the Turbo 10/30 is .085.
The were just quick easy to post numbers I have.

Of course HD's with the SL designation is a different story,,ranging from 1.0 to 1.6 that I have seen recently.
