Personally Pennzoil! I've always gotten my best mpgs with Penn and wear is low. Could be from the Moly that GTX is missing. All I know is just a bit better on Penn then GTX.
Is there any truth about Moly and better gas mileage ????
Havoline has a ton of moly, twice as much as pennzoil and I still stand by my statement. Even comparing the 3 oils I have always gotten my best mpgs with pennzoil. I wouldn't call Moly the end all bee all to mpgs but it could be a component.
Pennzoil
I just bought a 4 litre jug of Pennzoil for 7.00!!
wooo, looks like Pennzoil 5W30 for next oil change.
oh, Pennzoil.

GTX tested a little better in this report https://www.amsoil.com/lit/g1971.pdf over Pennzoil, so I would probably choose GTX.
I like GTX, but I wouldn't object to using Pennzoil either. They're both good oils, can't go wrong with either! I say take one quart of each, and have someone put one in each hand behind their back, and pick one
It's purely personal preference. Pick one and be happy!

Honestly: flip a coin, as both oils have shown good results on here, and one engine might prefer one over the other but the results should still be very close.

Oh, I want to vote. PENNZOIL
GTX but both are fine. I actually am more likely to buy pennzoil cause it seems to go on sale more frequently around here.
