15W-50 Mobil 1

[dan58]

Has anyone tried it? I hear it's a nice fix for old motors like mine (1972). Any reason not to try it?

Its not a bad lubricant. You can also try Modil 0W50 :t:

0W-50? Interesting.

I currently am using BradPenn 10w30 oil in my amx.

Got 5w40 in the Hemi and Suburban - no complaints. Can't say that I had much if any improvement in gas milage though :-|

I just put 15w 50 mobile 1 in my 360 Sunday. The idling oil pressure when hot went from about 12 psi to 18. Running at 55 is a steady 40. I was getting ready to put in new oil pump gears and a mid plate. I am going to wait now. Some other users told me to try it. :lo1l: =D>

I have been using it for a little more than a year. Normally about 60psi driving and 20psi idle at operating temp
