Owner reviews for engine oil

STP is their house brand. This is ACEA A3/B4 rated, which is what you want. You're not going to get anything VW 502 or 508 rated, since they're not going to pay for that accreditation. It's good enough.

Castrol Edge 5W-30 for me. I live in Vegas where it barely gets under 30 degrees in winter even so it's a better oil for the hot climate in live in

I used mobil 0W30. Seems like they're one of the few that make it

Any major brand of the correct rating and viscosity will work.

That being said, I have an 05 that was used as a DD for 12 years. Short trips, 3 days a week. After 12 years and 47K miles, I added a aftermarket supercharger. Put another 20K on it, including trips to the drag strip and track days.

I then had it rebuilt with forged internals because I wanted higher boost and more power. When the engine was pulled apart and measured. There was no wear. The cylinders were still within factory specs as was the crank.

I had used Amsoil SS 0W-20 the whole time.

I use Mannol 7715 on my 3.0tdi

Fuchs Titan pro 5w50

Fa20 DIT..Castrol edge Euro..0w 40 winter, 5w40 the rest..111k miles, stock block, E85, 400ish whp, drive like I stole it..I change it every 3k, 4k a few times in a pinch...I also run an IAG street AOS

Liqui Moly all day. Now that i’m over 200k in my Touareg i’ve been getting the light green containers which makes any oil leaks detectable with a black light. Not that i’ve had any but i think it makes it easier for my tech if ever the situation arose. As for filters Mahle, Mann, and Hengst are the go-to’s.

Mobil1 and Castrol are all I’ve ever used on my 266k mile 09 rabbit. I replaced the valve cover in nov 21 and that engine was super clean inside. Still runs very well.

My 1.8T has just over 103k miles. I got it at 78k, and until about the 95k mile mark, I've been using M1 0W-40, then switched to M1 5w-40 Truck and Turbo-diesel, since I wanted peace of mind with its extra additives and protection. I figured since this oil is meant for high operating temps and high load in turbo-diesel engines, it would be just as good in my daily-driven and weekend-tracked 1.8T. I change my oil a few days before going to beat on it over the weekend, otherwise I'll change it every 3k to 5k miles. Also, I have had some valve noise (tapping of some sort), the whole time I've had the car. I'm guessing it's lifter noise. I'm not sure, but I was told to try a heavier weight to counteract it, hence the switch to the only decent 5W-40 sold on base. Still no difference in noise.
