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 10w-30. 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).
