Now debating over AMSOIL or some Rotella from my stash......
I am an AMSOIL dealer but yet I love running HDEO's, I have been researching VOA's and UOA's for a week and it seems the Rotella T5 has less moly. than the AMSOIL but AMSOIL is a tad higher in ZDDP's and Calcium, and I'm pretty sure they are using calium as an ester in this case (a detergent or cleaning agent).
I would like to try regular Rotella in the summer but not sure about the 15w yet, it does not get all that hot here in central PA and some small engines react better than others with 15w. I have had UOA's go south with silver and other heavy metals when I switched certain small engines over to 15w........ I write it off as lack of flow capability @ startup on summer mornigs.
please let us know more. I feed off info like this.
