I use to use shell synth. in all my cars, but have lately been getting good deals on Red Line after getting a job at a new shop. I have reservations about using really good oil to break in my new 4.0, so just wanted to check. Should I just use the regular type to allow the break in process to happen correctly and then switc to red line after a few changes?

Redline specifically states not to use their oil to break in an engine. Personally I use dino oil for the first two oil changes (1500 and ~3000) and then switch to synthetic. Redline is good stuff. Enjoy your new engine! -justin   Ryan Roundy (Rrefxut) Member Username: Rrefxut Post Number: 89 Registered: 12-2003 Posted on Monday, March 22, 2004 - 04:16 pm:    Yup, that's what I figured.

Pointless to waste good oil on such a short period.
