Havoline Supreme

[211311]

Found some Chevron supreme in the SL vintage at Tractor Supply $1.68/Qt. How would this stack up against SM vintage Havoline for the same price? 10w30 and 10w40 weights.

Your title says Havoline Supreme. SL will have less zinc/phosphorus and less volitility. But they should be pretty close.

Havoline vs. Supreme

 

[Ray H]

"SL" has MORE zinc/phosphorous.

 

[Highroller]

i think SL should have more.

I think it will have zero effect in the differences of lubrication in your engine for 3-4,000 miles.
