Is it ok to switch between synthetic to dino?

Since synthetic doesn't stick as well to bearings I was thinking of running dino oil for when I store the car in winter and run synthetic in summer.

 

From what i know you can change oils as many times at you want.

Some people dont suggest using synthetic oil if your engine has high miles on it due the fact that it might start leaking.

 

Personally I wouldnt worry about.

Hey, isnt it a little late to be storing it, winters almost over!

 

My engine builder recommends 10W40 Quaker State dino oil but alot of the local guys are running synthetic.

He is also pretty old.

Would it be a big deal if I switched to Mobil 1 10W30 synthetic? I'm looking for some extra horsepower, heat disipation, and getting the oil back to the pan faster.

What could go wrong?

My oil pressure with 10W40 sits pretty high at the 3/4 mark.

 

Dude its just changing oils. No big deal. I've just heard that sometimes if guys with high mileage change to synthetic they get leaks. SOMETIMES.

As for extra horsepower......uhhhhh....NO!

Use 10W30 synthetic and let us know how it goes. If anything your oil pressure will be down a few points.
