Engine oil Mobil or RAVENOL

I’ve been using Mobile 1 since I’ve purchased my RAV4-brand new. Now at 160xxx miles with no oil burn. Runs like the day I bought it

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

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.

If I could change the oil myself I would do it every 5k using the cheapest 507.00 spec oil I can find. But I can’t so I do it every 10k and use Mobil1 ESP.

As long as it states VW502 on the back, you should be fine.

I used to live in Chicago, and had cut over to Mobil1 0W40 based on feedback from a very respected resource who worked for Porsche. For context, his recommendation was grounded in enabling my engine to better handle the harsh Chicago winter temps.

To be frank, I'm not sure if it made a huge difference but then again I do not have a chemical or petroleum engineering degree.

I drove my VW to 200k miles without any issues.

I used to have castrol but since i chiptuned my octavia i switched to ravenol and the oil temps went down a good bit and it doesnt use any oil but that could also be because the old oil was 0w20 and the new one is 5w40

Last month I replaced the valve stem seals and it helped massively with the smoke. It doesn't really smoke much anymore, there's definitely still small puffs when taking off quickly, but nothing that I can see in the mirror.

You can also try changing your oil to M1 15w50 full synthetic that helped me with my cold start rattling issues and the engine seems to run smoother along with the vanos idle clacking noises going away.

Personally I use mobile 1 extended performance and change every 5k but I’m a bit of an oil critic

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.
