Does anyone know if the Mobil 1 Full Synthetic oils contail teflon or anything that would hamper switching to a different oil after using them? How bad is it to switch to a non-synthetic oil after using a synthetic? Thanks

 

Mobil 1 has no teflon or any other solids in it. As far as the damage when swithcing to regular myth- it is just that a myth. Although, some higher milage motors seem to burn oil easioer with synth.

 

Does it cause your high motor to leak if you use synthetic?? My motor leak after I use it.
