Question ???

Jersey Titan · 03-26-2006, 09:24 AM

I have read all the posts about using synthetic oil, pros & cons. I have an 04 "LE" 4x4 and have changed from factory pensoil (dealer uses pensoil) to Mobil One at 9500 miles.

Question ?
Once I to change to synthetic oil, can I go back to factory/regular oil ???????
I now have 12000 miles. "Rumor control" states that once you change to synthetic, you can't go back. ?

P.S. My Titan still burns alot of fuel, so synthetic oil made no difference.

No problem, you can switch back or you could mix the engine doesn't know the difference.

I've been told that if you back to dino oil, the seals tend to start leaking.
There has to be an authority to ask if it's true.

I don't believe that, maybe 20 years ago. But todays engine seals should be fine. If a engine didn't leak switching form dino to synthetic, then why should it lead when switching back? It will be fine.
