Well after my motor swap, I started using 5w30 mobil 1 synthetic oil. Recently I've had a lot of problems, and basically got really frustrated and took it to a shop because I didn't feel like messing with it. They found oil leaks everywhere, and after they found and fixed them they changed my oil, but put regular 10w30 motor oil in. I wasn't quite sure if you were allowed to go from synthetic to regular back to synthetic, which is why I made this post..

To summarize: After using synthetic oil for a while (motor only has 35k miles on it) then going to regular, can you go back to using synthetic?

 

sure can. just drain the reg. and pour in the syn.

 

should not be a problem switching back and forth...

 

Thank ya'll very much.

 

not a problem
