Nope, price is the primary driving factor for what oil I get, brand does not play into my choice.
I used to favor Valvoline, but once I got here and learned more, I found it really does not matter all that much for my needs.
I rarely use the same brand oil for more than 2-3 changes, it really is based on what I have in my stash.
Several of my vehicles will be receiving Rotella Gas Truck for a while because of the clearance on it a few years ago (I have ~60 qts of it).
Only recent vehicle that has had the same brand oil for more than 3 changes is my Santa Fe, just had it's 4th (and last) change with Pennzoil Platinum 10w30. Not sure what will be used next, but probably some of the Rotella T6 0w-40 in my stash.
Just looked, of the 9 vehicles I service, I have 7 different brands of oil (Mobil and Pennzoil are the only repeats).
