quick question, AMSOIL ASL 5w30

[Johnny248]

Since the ASL 5w30 is not actually API certified, does anyone know if the Zinc and Phosphorus levels are still at the low SM rating? or does Amsoil add/keep more similar to the SL rating?

Still SM? This shows it rated for SL:

It is GF-4 though. Dunno how that impacts additive levels.

Quote from the website: "API SM/CF, SL, SJ ..."

No way of knowing unless you test it or if Amsoil will give you an answer.

Here is the latest UOA on the product in question and it looks like SM levels to me.

ASL has the lower levels of P and Zn to comply with "SM rating".

Oh, I didn't see SM along with CF since they were paired up. (glossed over the diesel spec since it's a sparker oil)

Thanks Pablo. So is there a better choice if the car originaly called for SL oil? 5w30 Diesel maybe?

If your car originally called for API SL then the Amsoil ASL will work just fine, as would any other API SM oil.
