Engine oil Mobil or OEM Volkswagen

I used to run 0W40 in Lexus IS250 (4GR-FSE engine) with great results, towards the end of it's life (maybe... the car was stolen at around 200k miles, so not sure when it actually died) it was burning little bit of oil when 5W30 was used. However, I have noticed that when I changed for 0W40, it has not burn any oil at all and oil was noticeably cleaner.

As long as the oil is VW 502 00 spec, it’s fine to use. I always go with either Mobil 0W-40 or 5W-40.

Mobil 1 Advanced in everything, with OEM filters... Use it in my Tucson, Mustang, Corvette, and Dodge pickup... Really, any quality full synthetic oil is fine.

Been using Mobil 1 5w-30 full synthetic since I rolled it off the lot. Zero issues. I do my own changes every 3-5k. I did swap out to the FL400s filter to make it an even 6qts.

I went back and forth between Mobile 1 and Amazon full synth for 140k miles without issue. Just change the oil every 5000-7000 miles

Mobil 1, Valvoline, or Motorcraft. Ive used them all and have no complaints so far, usually i use Mobil 1 since i can find the 6 qt box for a decent price at Costco.

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.

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.

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'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.
