Engine oil AMSOIL or RAVENOL

I use Amsoil 0w40 or Eneos 0w50 in mine. For sealing and shear resistance for metal to metal contact, thicker is better.

I run amsoil Signature 0w20.

I ended up returning the Castrol Edge 5W-40 and got AMSOIL European Car Formula 5W-30 Improved ESP Synthetic Motor Oil instead, which is VW Approved and 504 spec. Its quite pricey though, $180 CAD for 12 x 946ml.

Amsoil XL 5W-30 in my 2016. Swapped with a new OEM filter every 6K.

Ravenol VMP (best oil hands down for diesel).

FWIW, I've run AMSoil in my 2003 WRX since new, and I like it. What actually sold me on it was when I did my first oil change. The used oil still feels new when you run it over your fingers. And the engine still runs just fine.

I'm one of those people that uses Amsoil. I use their European 5w40 and change the oil every 10K or 1 year, whichever occurs first. Never needed to add any oil between changes.

I have been using the Ravenol VMO 5w30 formula that you can get through Blauparts.com, I have reduced oil consumption in my 2.0 TSI by using this oil.

I ran either Mobil 1 or Castrol VW Spec oil in my 08 2.0 TSI and had the usual high burn off with no visible leaks for 1st 100K or so and then switched to Ravenol VMO VW Spec oil I buy on line for a premium price but I like the fact there is little burn off in 5L change intervals which should equate to less carbon buildup in the upper intake of the heads. I have not done an oil analysis which would be helpful to know if I should be waiting to 7,500 or more before I change filter and oil. I had the misfortune of a valve spring breaking at 125K that lead to the head being removed and rebuilt at VW Dealer, the head mechanic was amazed how clean engine was (Mobil 1/Castrol) and the honing lines on the cylinder walls could still be seen indicating very little if any wear. I'm at 156K and burn about 1/2 quart every 5K and engine is as tight as Day 1 with APR Stage 1 Tune

Here is what I've been using on the Gen3 1.8t (2014 passat) - http://www.amsoil.com/shop/by-produ...otor-oil/european/european-car-formula-5w-40-synthetic-motor-oil/?code=aflqt-ea . Works really well with a 5K OCI.
