Engine oil Mobil or LIQUI MOLY

I'm doing mine a little more frequently now at 280,000km. I do every 7,500km with liquimoly molygen.

5w40 is fine for the summer.. I would go with liqui moly next time if the prices are similar.

(2013 VW GTI) Used to use this exact oil and noticed LiquiMoly 5W-40 (they even have a UV dye version if you have any sneaky oil leaks) performed better for my car specifically. I do frequent changes 3000-4000 miles and the oil doesn’t seem so burnt, I experienced less oil consumption, and the engine oil temp seems to sit slightly lower as well.

If you're skeeved out and want to return it, I usually go with the knuckleheads over at [ShopDAP.com](https://ShopDAP.com) (love their VW/Audi YT channel too). They seem to be Liqui-Moly fans and have kits for the Golf and other 1.8TSI vehicles that you can buy. I use Liqui-Moly 5W-40 and it works great, if maybe slightly pricey. I used to use Mobile 1 0W-40 Euro Car Formula in my old Audi S4 and it would probably work OK in these engines too but I wanted to stick with 5W-40.

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’ve always sworn by AMSOIL and I’ve never had an issue with it. I just got my ‘21 GT and I think this time I’m gonna be running LiquiMoly through it. I’ve read a lot of good things about it so I’m gonna give it a shot and update this thread

I can only vouch for LiquiMoly Street Race 10W50 which I used on my 2014 Daytona 675, and that reduced the cold start sound and vibration, and the engine generally ran quieter than with Castrol.

I've been using this exclusively in 3 of my cars. 2004 ford mustang, 2008 Chevy Suburban and a 2015 Mercedes CLA 250. All cars are over 120k on the clock and none have any excessive wear or leaks. I change the oil every 5 to 6k miles. No problems yet. It's a very solid product.

It’s all I use. No issues, I can’t say for sure if it made any difference with anything but I trust it.

A bit in the expensive side, but I use it and several Liqui-Moly products.

I just did the chains + headgasket and a bunch of other misc stuff on my Corrado earlier this year. My guides were worn pretty bad and it only had 120k on the clock.
