Engine oil Mobil or OEM Volkswagen

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.

I’ve been running mobil delay esp 5w40 it’s been working well for me.

I've always put Mobil1 High Mileage in my 2013 Scion tC, IIRC Mobil1 is what Toyota uses at the factory. I had a heavy upper oil pan gasket leak that's largely stopped since switching to high mileage oil.

5w40 if its drinking oil during vtec, I usually use Mobil but get whatever cheapest

My Mk4 Golf is at 146000. And I've religiously changed oil and filter every 4000. One time I let this synthetic oil go for 9000 miles, it caused pre-ignition and destroyed 2 sparkplugs, needed a tow, and a expensive sparkplug replace at VW.
