Owner reviews for engine oil

I personally use Mobil 1. They all do basically the same thing if you're changing it often enough. I change mine between 3-5k miles typically.

We run LiquiMoly 5W-40 in all of them. UOA testing of heavily modded cars shows significantly less wear on engines running LL-01 oils vs the LL-14FE piss water.

I used the mobile advanced fuel economy, I live in a pretty mild climate. I have seen lots of people swear by asmoil it's supposed to be good.

From my own experiences, M1 is excellent. Been putting it in my 30 year old Celica for 7 years, gotten 160k miles out of it, 320k miles on the original motor in total. My buddy’s Corolla had a bad timing chain slap on startup, went dead silent ever since swapping him over to M1. I just stick to what I know.

OP, love the choice of Pennzoil Ultra Platinum Ultra Synthetic! Anyways, does the jug of Pennzoil Ultra Platinum seem a lot lighter than other 5 qt jugs of oil?

I use Castrol as it’s the OEM product and is cheap if you buy direct from Ford.

I’ve used Mobile 1 full synthetic for years, most manufacturers warranty it.

I *always* find Pennzoil Platinum on sale for like $25-ish/ 5qt at either O'Reilly's, NAPA, or Walmart around the time I go to do my oil change. $50-ish total oil changes, never had any issues with any of my cars.

Mopar oil filter, amsoil 0w20, don’t over torque filter housing.

I've noticed going from cheap synthetic 5W-30 to Liquimoly 5W-40 seemed to help a little with my intermittent light issues.
