Engine oil LIQUI MOLY or Castrol

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.

5w-30 Castrol LongLife in mine in Europe. But often interchangeable, but always depending on what the manual says. Top thing though I’ve found after 120k miles in on a TSI is: keep it near top of dipstick to bypass chain and turbo issues (turbo especially relies on good oil supply). Listen for rattling chain and listen to turbo note, can often hear changes and usually due to lower oil level.

I had a 2009 VW Rabbit, and I'd often buy Castrol Syntec (full synthetic). I haven't seen this 'Euro Car' formula, but it says it's full synthetic, so I think it would be fine.

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.

Castrol a good engine oil, albeit more expensive. Stopped using them when the price went up significantly

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).

If you want to do 5k oil changes, best to switch back to Castrol GTX or any cheapo oil as you'll have no significant advantage using synthetic for short periods of time.
