Oil change on FJ

[spaldam]

I'm on using any trements. A good sythetic is really the best way to go.
I've used Slick 50 and Prolong in the past with no noticable differance. Slick 50 caused foam to form in the oil, so I figured it probably wasn't the best thing to use.

Slick 50 is a once every 50,000 mile treatment not every oil change. I don't think the foaming was an issue on the vehicles I've treated.
