Engine oil LIQUI MOLY or Shell

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.

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 used it often this product and like it very much. (I used it in my 2005 E320 CDI; I haven’t used it in my W123).

I've been using liqui moly for a while now and its been great.

As to which one, the two that are reported to induce the *least* consumption are Liqui Moly Leichtlauf, and Fuchs Titan Super Syn.
