I've read on here before that it's fine to mix say PP and PU. But what about adding a third brand in there?
Say the car wants 4.5 qts. So you put in 2 qts of PU. 2 qts. of PP. And half a quart of motorcraft synthetic blend. Keeping the same weight and viscosity.
Is mixing the motorcraft in with the two pennzoils going to be an issue?
