5W-50? too viscous for new car warranties.

201 VI. Really?

Phosphorous may be high enough to kill a cat. We have emissions testing.

Not near enough info there to make an intelligent decision.

SAe 5W-50
Iso 100

A broad range and a narrow spec. hmmmm.

Nope, not buying it.


Why would the phosphorous kill the Cat. if my engine is using less then 1 qt in 20,000 miles,which is my actual case on several cars. There has been actual emission tests done with synlube to back this. I have never had an emission issue with synlube.

The EPA,FTC,and so forth would be all over the company if that were the case. Yet no issues there as well.
