Engine oil Mobil or RED LINE

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 use Redline but it’s about the same price if not moreso.

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 use Redline 10w60.

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'm running Amsoil 5w40 or Castrol Syntec 5w40. I ran Mobil1 10W30 a few times and I heard too much valve noise. When I opened the oil cap after driving around on the freeway it was smoking..which I'm not all that happy about. So I stopped using this oil.
