That's not the case and the starting the engine part sound like something
froma Slick-50 commercial. Synthetic and Dino oil do mix and you can switch
back and forth as much as you'd like.
You're fine with the oil for the temperatures you described.

I think that the lighter weight oil has a bit harder time sealing the piston
the the cylinder wall at first.... but then gets going.... and I dont think
that you can go back to regular after you have changed to synthetic cause it
leaves a slight film on the parts that reg oil cant adhear to well and when
you first start up you just grind metal, sort of. Thats what Ive heard
anyway.... any truth in what Im saying here guys????
