Engine oil Mobil or AMSOIL

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.

I use AMSOIL signature series 0W-30 but the Mobil-1 suggested by others is totally fine — AMSOIL is awesome but is expensive.

I ran Amsoil in my 2002 7.3 for years and it worked well for me.

I use 0w40 Mobil 1 all year round. I live in upstate New York, so our winters can get pretty cold at times, and summers can be in the 90s F for days at a time.

My V70 2.5T is almost at 190k miles. I add about 1 quart of oil between oil changes at 5k intervals and my car has been trouble-free since I purchased it at 107k miles in 2017.

Do not cheap out on oil. I use Mobil 1 high mileage but Castrol is also good.

Valvoline is ok, but that specific oil does not have the rating required for your vehicle. AMSOIL has by far better additives to clean/restore the engine. If you are currently using AMSOIL, then continue using it.

I used Amsoil 5w40 European Car formula or Gulf 5w40 Formula G in my A6 previously. Technically Amsoil doesn't have the have the VW 502 00, 505 00 certifications so I think I will start using Gulf Formula G or GX exclusively in my R, either the 5w40 or 5w30 grade.

im actually running that oil right now... I hate it tbh. 3,100 on the oil and it has allowed excess engine noise since day one, SUPER harsh cold starts, and now its burning through faster than the catrol I ran when I first got the car. a WHOLE QUART over 750 miles. the oil is thinner than piss going in, and it just doesnt stand up to what my engine can put out like Shell Rotella T6 has been doing...
