no it doesnt, the thicker the oil the more chance to starve the turbo bearings from oil you have, the oil pasages on the turbo are small therfore using a 20W50 is just looking for trouble, you dont see the effects now but soon you will by starving an engine and turbo

The maker recommends 20W-40 for hot weather. Anyone using it? Has anyone ever seen 20W-40?

I had always ran 5w-30 then I switched to SSO 0w-30, then to Dominator 10-30, and now that I have the FP Red, I switched to 10w-40 and it take a while to heat up. Now, my car feels like it don't want to go, untill it is warmed up.

When I talked to a rep at Amsoil they told me to run Dominator 5w-20
