Engine oil Mobil or IDEMITSU

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 use either Mobil 1 ESPx2 European Car Formula 0W-20 available at Walmart or Valvoline Full Synthetic European Vehicle 0W-20 from NAPA. Both are approved VW 508 00 oils and can be cheaper than the oil at the dealer.

Throughout the summer I was averaging a quart every 750-1000 miles, still using Mobil1 15w50 & Viscoplus. This winter it dropped back down to 1 quart every 500 miles, but as the weather has warmed up, my consumption seems to have decreased again. I think that had something to do with the oil, which was admittedly way too thick for cold weather. I would let the car warm up a couple minutes before driving because that oil is syrup in cold weather.

I have been running Mobil 1 0w-40 since new with over 50k miles on different Big turbo(80k total miles) setups and always replacing seals and gaskets due to oil leaks(its some really thin oil).
