Engine oil Shell or PENNZOIL

I use Pennzoil "Ultra" Platinum for my 2010 with 5.4 Triton and it runs amazing. At one point I did try Royal Purple but my engine was actually noticeably noisier so I switched back.

I only use Pennzoil platinum ultra. Only the finest for my baby.

Penzoil full syn platinum on my 02 and she’s chillin. I’ve never had issues

Oil consumption was the biggest issue when running 5w30. Changed to a 5w40, 10w30, and then got recommend 15w40 and oil consumption stopped

Rotella T6 ! Zero issues.

So far itong si Shell yung may pinaka smooth na oil sakin.

I usually buy Pennzoil, it's inexpensive and it works. I check the contents first to make sure the oil isn't full of gunk in case someone swapped it. I do oil change every 5k km, which is once every 2-3 months, hence I don't worry much about too much gunk as I flush it out often.

I use the Penzoil Platinum Euro LX Full Synthetic 0W-30. No issues past 2 oil changes.

Rotella T-Syn is a great oil but for our turbos...i wouldn't recommend it since if any oil gets burnt or makes it way through the rings...the higher amount of ZDDP (zinc) found in the Shell Rotella Synthetic oil will be harmful to your catalytic converter which may cause a failure.

Stay away from rotella conventional. I’ve heard and now as well personally have had a turbo grenade due to their oil quality, that’s the conventional anyways.
