I had a cheap Volvo S40 commuter with bad valve stem seals back in 2011. I was about to tear into the engine, when a trusted friend/parts manager/guru recommended I try a can of Liqui Moly Motor Oil Saver as a last ditch effort. Within a couple drives the symptoms were gone, and last I heard the car is still running strong today.
I went with Liqui Moly 2332 Leichtlauf High Tech 5W-40 which meets 502 spec. This. German-made. 502 spec. You can get a jug of the stuff on Amazon for a good price. Been using it for over a year now.
LiquiMoly Leichtlauf High Tech 5W40 Easy DIY kits sold online for ~$70 delivered including VW filter and drain plug, has a good reputation in the VAG community
I just did my first oil change at 1k miles. I went with Liqui Moly 2332 Leichtlauf High Tech 5W-40 which meets 502 spec.
I've been using the Liqui-Moly 5w-40 Leichtlauf High Tech since 2500 miles.
You want to know how your oil is doing? Send it to Blackstone labs for testing. Cost $35 but worth it in my opinion. I send my 8k oil (Liquy Moly, from my CC) and it was still very good!
This stuff is amazing, totally worth the extra money.
I use this for ever oil change and I've had no problems, CEL, or oil consumption. I drive it hard with autox and have done 20+hour road trips.
Liqui Moly makes some excellent products.
I can confidently say this ‘leichtlauf’ oil really makes a difference. The engine feels healthy on cold starts, hot starts, hard acceleration, etc. Use this oil????????
