Engine oil LIQUI MOLY or Castrol

Liqui-Moly Leichtlauf 5w40 FTMFW! Switched at \~30k and now going on 90k...both run smooth as silk and don't burn any oil at all...

A3/B4 is a rating for just protecting the engine.

Castrol edge 5w-30 LL is oil with just C3. So it's mostly for protecting DPF. If you have a diesel engine with DPF then this is a good choice. If not something else would be better.

I used the correct spec 0w20 for 150,000 miles and then switched to 5w30. We’re at 208,000 miles now and running great. Always LiquiMolly

You're going to be fine with 5w40 the thinner oil is for fuel economy but heavier oil will make your car last longer so that's the tradeoff.... If you are in a warmer climate then a lower starting weight would matter but I'm in Canada and I'll be running 5w40 liqui moly all year every year.

Also will help with oil consumption.

I switched to synthetic after doing a piston soak. Sticking with synthetic here on out. I initially ran conventional Castrol 5/30 then blend as conventional was not available through Amazon and then synthetic to try to stave off carbon build up on rings after a successful piston soak.

Been using Liqui-Moly 4200 5w30 and I don't lose/burn any oil (yet).

I too have a 2013 passat with the CKRA, I’m currently at 175k miles. I do my oil change every 7500 miles. I only use liqui-moly top tech 4200 5w-30. I usually never have to add oil between changes unless a lot of hard driving in the summer.

I have have had very good experience over the decades with Liqui Moly 5-40 and Total Quartz 9000 5-40 Both are excellent motor oils

Doesn't really matter that much, we ran 0W-20 for a while and now have 0W-30 A5 in our Civic.

The new LM MolyGen or whatever it is called is not as good as the oil that was discussed thoroughly in this thread. I strongly recommend you stick to the LM Leichtlauf (part number 2332). If you engine sounds \"angrier\", and if that's not in your head, then that is a bad thing.
