Hi Friends,

So I have read Richard Atwells artice on distinguishing between oil grades several times http://www.ratwell.com/technical/OilSelection.html

Now.... I am still baffled. What type of oil do you run in your 2.0 aircooled Vanagon? I live on the California coast, but venture into the valley occasionally (So temps will range from 50 in the morning to 100 in the afternoon. It seems like 10W40 or 20W50 would be best. I just entered the aircooled world, and am curious who has had good luck in similar weather conditions with their grade.

Thank You All,

J

Typically, an aircooled motor is going to run hotter than a water cooled. This is especially true on a hot day. Therefore, an aircooled (at least theoretically) would benefit from a heavier oil in the heat to prevent breakdown. This is a highly debated topic, hence my question.

20/50 Castrol GTX will do your AC engine well.

I have been running Mobil 1 15W-50 synthetic for years in ACVW's, it seems to handle the heat very well. You don't get that dark blackish crud building up inside the valve covers you typically see on engines running dino.

To summarize: Those of us who've been plugging Castrol GTX Dino have been doing a very good thing!

Best!

To further summarize, you gotta keep an eye on the oil suppliers. They may change their formulation without notice. Delo 400 and Castrol GTX remain OK for the time being...
