Engine oil Mobil or PETRONAS

Mobil 1 is my go-to... mostly because the level gauge on the side of the container is easier to read than any other brand. I've been using it in my 2018 since new and have never had an issue. Odometer is currently at 260,000.

I have a 2020 Corolla se with the 2.0l and I use 0w-16 from Mobil 1 which makes Toyotas oil for them.

Mobil 1 15w-50, Viton o-ring from any automotive or industrial supply house, Wix or NAPA(mfd by Wix) filter.

I use Mobil 1 15/50 in the engine, rotella t 15/40 in the primary, and Mobile 1 75/140 in the transmission.

I was using 0w20 because of price but got some mobile 1 deal 0w16 for cheap so I'll try that and see if I get better MPG (currently 35-42).

Google the Mobil 1 “million mile car”.

I run Mobil 1 Racing 4T 10W-40 oil for my ZX6R. I love it. I change it every 3000 miles.

Anyway, the only 508.00 spec oil I've found locally has been this Mobil 1 ESP X2 at Wally World. (walmart) Anyone else running it? Anyone seen any deep analyses? I put lots of Mobil 1 Delvac through 2 TDIs totalling 485k miles, so I'm willing to bet on this Mobil 1. I like being able to pick it up locally, and at only $28 for 5 quarts!?

I will say I've done my last 3 oil changes with penzoil platinum and my engine rode rougher and louder than it did before with the Toyota oem oil. So this past time I tried mobil 1 and it's way quieter and rives smoother.

I know when I put my stroker block in with stock head/turbo I filled it with 0w-40 and I would get low oil pressure when deaccelerating down hills.. Low enough the light would flash on, got my freaked out! with the new head. and my 71r 72a/r set up going on I'm swapping to 10w-40 mobil 1, because when I took the old head off there was a TON of carbon build up for the small amount of miles I had driven the new block around(less then 2,000 miles). I had changed the old twice already(once ot get the break in oil out and once again at 500 where I dropped the pan to check for metal and such and up in a new pick up tube for piece of mind). I have good reason to believe the 0w-40 is just too thin for the clearances for stroker pistons and such. I'll report back once the car is up and running with the 10w-40 in it. If the oil pressure problems persist I'm thinking about stepping up to 10w-50, but Im in southern California so YMMV depending on how cold/hot it gets around you.
