I've done the search and read thru the topics about AMSOIL Synthetic oils and Fossil based oils.

My question is. Is anyone using a synthetic blend oil?

I've been a long standing Rotella-T user. I've been looking at the AMSOIL Synthetic Blend oil. The AMSOIL site says it has outstanding performance at temperature extremes, but they don't list the temperature ranges like they do for their synthetic oil line. I've also heard that Rotella now has a Synthetic Blend product.

I'm not looking to reopen a debate of oil, just trying to find an opinion on the Synthetic Blend oils.

Also. Anyone try the Rotella-T Fully Synthetic Oil (5W-40) ?
