Anyone familiar with a Pinzgauer? I need a recommendation for engine oil for an air cooled Puch motor. I am currently running 15w40 Chevron in it. These things have quite a condensation problem so I think I will most likely stick with a conventional oil as it will be changed often. Any brilliant suggestions? I also intend to change the 8 gearboxes to something synthetic. I used Redline shockproof before in my unimog with good results but Redline recommends the 80-140 instead of the shockproof. Why do you suppose they do that? thanks in advance.
