Owner reviews for engine oil

I've used liquid molly for years now, and it's the oil in my 23 GTI right now.

I use Motul 8100 EcoLite in mine. Paired with the appropriate Motul fluids in the trans and diff, and RBF660 in the brake lines.

I have a Fit 2019 and switching from 5w30 to 0w20 improved my mileage from 650 km/tank to 800 km/tank.

Just got in two 5 liter jugs and very excited to fill my Escalade. I currently have in Liqui Moly Special Tec which has run exceptionally well.

Yesterday I took my car in for an oil change and got amsoil. I read countless comments of people hating on the price, this and that, but let me tell you somthing, that amsoil ain't a gimmick or a rip off. My car drove sooooo much better afterwards, it kinda shocked me. Smoother, seems faster, more. Consistent shifts, just left me feeling like she felt the best version of herself.

I use Castrol for my 05 320 cdi. It meets the extended service oil spec, but I run it as "regular" oil.

Liqui Moly 5w40, MB 229.5. Only that one, even though it is PITA to find in Finland.

Local Merceses dealer put Shell and I don’t really have good experience with Shell before so only Liqui Moly for my car.

I use Mobil 1. Meets MB spec and can get 5 quarts at Walmart for $30.

The 2.0 liter gas/petrol engine is the weak link here, due mainly to poor piston ring design. We are third owners of a '14 A4 6MT, purchased in mid '17 with 48K miles. We're at 98K miles now, and with 5K engine oil changes using Liqui Moly or Elf/Total fully synthetic, we use a small nominal amount of engine oil between changes.

Stay away from the XD3 oil. I ran it for 30K on a rebuilt motor and experience extremely high bearing wear. I ended up with low oil pressure.
