Not a problem. I wasn't very clear in that, and virtually always on this forum warranty means vehicle OEM warranty. I guess it comes so many years of looking at things from the oil wholesaler's point of view and assuming everyone else does too.
Quaker State-Pennzoil frankenblend?

My 5.4 3V has three or four different grades of dino, synthetic and hm oil mixed together and is running fine at 215,000.
Nothing wrong with a good Frankenblend! We even had a recent (last year) thread dedicated to our mixes:
Post your latest FrankenBrew
Just did 10,000 km / 6,200 miles on a FrankenBrew of Penrite Vantage 10W40 semi-syn, Valvoline SynPower 0W40 full syn, Castrol Magnatec 10W30 semi-syn, Castrol Edge 10W30 full syn and Valvoline DuraBlend 10W40 semi-syn.

I mix 50/50 QSFS and PUP in the winter for extra protection and the moly. Just did my 5k OCI and my GF's Forrester with it last night as a matter of fact. I'm 5W30 and She's 0W20. I save my PUP for the winter since it's $$$ now and run QSFS straight the rest of the seasons and since I have a stock pile of it.

So going through the odds and ends in my garage, stuff I had leftover from my old car, my next oil change will be
1 qt Pennzoil Platinum HM 10w30 SP
1 qt Pennzoil Platinum HM 5w30 SN
1 qt Pennzoil Platinum 5w30 SP Dex1G3
1 qt Quaker State Full Synthetic 10w30 SP
That leaves me .5 quarts short. The engine is a Buick 3800 Series III from 2005 with 154000 miles. The current fill is PP 5w30.
