Rotating Full Synthetic with Conventional Oil

[Mr_Luke]

Is it OK to rotate between full synthetic and syn blend and/or conventional oils?
I went to an out of town Walmart and they have Super Tech full synthetic for only $14.36 for 5 quarts so I bought one.
Their ST conv is $13.68 for 5 quarts.

I have a 5 qt jug each of NAPA SB 5w30 and 5w20.
I like ST oil tho I won't need an OCI for 6 months.
I just did one a few days ago.

And if I do run full synthetic, it's OK to run an OEM, Federated PG241F, or Fram PH3614 filters with it?

Of course.

Make your own syn blend.
Sounds like a plan.

The ST conventional is most likely really semi-syn and has the same group III as the synthetic in it so switch or mix away.

IIRC someone posted that conventional and syn WPP oils have the same ad pack. If true you could mix 50/50 and get a 75 percent group 3 without any concerns about mixing additives.

Edit...

Forgot you said you had NAPA oil in the mix. No big thing. Switch away.
