Engine oil LIQUI MOLY or Castrol

12 Galant 2.4 always running Castrol edge 5w20 and oil filter change every 5k miles for like 60k miles now has 126k. Cars have never shut off or left me stranded or left any signs of hesitation.

I replaced the cam adjuster magnet and haven't had a problem since and I changed the oil( I used liqui-moly this time).

Last change I did I switched to liquimoli 5-40 and I used a can of Cera tec. Noticed a bit of quieting from the engine after a few miles of circulation and after nearly 5k miles I'm only down mayyybe 1/4 QT. So far so good at 131,000

Generally, brand matters a lot. Amsoil, Mobil 1, and Castrol are all great.

I run Castrol in my older cars and Mobil 1 in newer cars that I care more about.

I usually change the oil every 7500 miles and tend to use Castrol synthetic 0-40.

Molygen (the green stuff) is recommended by Liquimoly for VW 502, but it does not actually have official approval from VW for the 502 spec. Just something to be aware of. I buy the liquimoly leichtlauf which has the official approval from VW.

I just stick to LiquidMoly. It's been in there since I bought it and the difference of $20 bucks over the course of 10K miles isn't that big of a concern. It's worth the slight piece of mind.

I just use German made Castrol Edge 0w40 (502 certified) oil. Ive used this oil since the car had its first oil change and it does not burn a drop and car runs great, i now have 59k miles and shes drives new as ever.

I live on the west coast and use 5w40 LiquiMoly from NAPA @ $36/5 Lt. It made my CF life go from replacing every 10k miles to getting nearly 20k miles/CF.

I've run somewhere between half a dozen and a dozen oils over the last few years with oil analyses for all of them and both the analyses as well as my own personal observations favor the LM by a bit over other high quality full synthetics offered by Motul, Redline, etc. Specifically you want this one: https://www.amazon.com/Liqui-Moly-2332-Leichtlauf-Engine/dp/B00LIC29H6
