Air Cooled Engne Oils

[oasis]

I used Royal Purple Max Cycle in my '71 Super until the day it died.

I will be using Porsche Classic 20w50 when it becomes available in my '74 Thing.

Porsche's release

I'm sure folks will poo-poo the necessity and others will jeer the probable cost, but I respect Porsche for still recognizing and supporting its air-cooled past. In the end, oil changes are the best and cheapest insurance one can buy.

(While VW doesn't address its air-cooled past except for stray t-shirt or key chain in Driver Gear, they do recommend all sorts of different engine oil for their different engines, so I believe in mating the right product with the right product.)

Hi everyone, I talked to a machinist this past weekend, I've been having oil pressure problems.Our topic digress to oil additives, since he was looking at our entire engine for possible problems and oil supply and pressure. he noted our cam lobs, reminded us that we should add zinc while breaking in the engine. he sell small containers pint size, more like 6 ounces of zinc additive. Has anyone ever heard of zinc additive? also he stated that the zinc was only needed during break in.

I've been using Liqui-Moly additive...but have no idea/evidence if it works or not! But I'm sure it's better than nothing...
