How Much Oil??

This drive in an oil cooled classic was brought to you by our friends at Dues Customs.

A classic Porsche 911 is an iconic and aspirational car – c’mon, you know you’ve always wanted one. By “classic” we mean a 911 with an air cooled engine.  Technically, it is actually oil cooled.  Engine oil is pushed all the way to the front of the car where one of a number of variants of oil-to-air heat exchangers cool the oil before it is sent back to the business end of the car. That’s a lot of plumbing! In fact, the oil lines themselves hold up to two quarts of oil, not counting the sump and crankcase! So how much oil is in the full system?  The Porsche manual, while known to be hyper-precise in nearly all respects, prefaces the oil capacity figures with “approximately.”  So, depending on which type of heat exchanger(s) may be on particular car, the capacity is “approximately” 13 to 14 quarts!
