My LS was turbo for about 8 months or so and during that time i switched to mobil 1 fully sythetic. i took everything off my car and kept it stock for about the past 4-5 months or so, and ive kept using the sythetic. i was wondering, is it harmful to switch back to regular? the car is strictly a daily driven stock car now, is it still harmful to go back? thanks

 

What are the benefits of synthetic?

 

No, it's not a problem to switch back and forth.

 

 

thanks
