Engine oil LIQUI MOLY or VALVOLINE

I switched to valvoline restore and protect on my 06 is250 and it’s working great. The valves are a lot quieter compared to the previous oil I was using which was Kirkland synthetic.

I have a 14 Passat. I do full synthetic LiquiMoly with the VW spec. I change it out every 6-6500 miles.

Liquimoly leichtlauf 5w40. Been told it’s a bit better than 5w30 in a 20+ year old engine due to being a bit thicker. Also does better at higher temps and I drive like a dick

Liqui Moly leichtlauf hightech 5w40. Because it matches the BMW LL-01 specification and was formulated to help with the sticky piston rings issue common to many german engines. Noticed lower oil temp under load and a gradual reduction of oil consumption

Quaker State oil is recommended in the Hyundai manual but you can absolutely use other brand too , i have used Mobil 1 / Vavoline / Castrol and Pezoil the end i picked Valvoline high mileage Synthetic oil the best of all all other brand the oil burn brown quickly

I run LM 5w-40 as recommended by my tuner.

I just do the liqui moly. Also I change my oil well before the BMW recommended 10k.

I used vavoline for my second oil change and so far so good

I often go for liquymoly or Motul 4t 10-w40 fully synthetic oil for my big machine.

For those who aren't certain about which oil to use, I've read that the "fully synthetic" oil in the USA really isn't fully synthetic and the Liquid Moly stuff from ECS tuning might be a notch or two better than the Mobile 1 from WalMart*.
