Bear in mind this guy is talking about airplanes and VERY VERY high standards of what is 'acceptable' for such an engine. While the basic points of humidity, condensation, loss of
oil on the surfaces over time and acidic properties of water mixing with
oil are all true, I wouldn't loose any sleep over it. Well, unless I was FLYING the plane were talking about.
Fact is many people park their Cobras for extended periods of time. Just check out the typical LOW mileage and compare that to time of ownership. 500 to 1500 miles in two years or more is pretty common. So does engine 'corrosion' occur over this time frame? Well yes and no, I believe from a practical standpoint it's not that big a deal for a car engine.
The BEST points in his article?
Oil has drained from the surfaces of an engine that has been sitting idle for an extended period of time. Initial startup would call for a LOW rpm while the oil is being redistributed. This also makes a STRONG case for light weight oils, like 5-30 wieght, so it's circulates faster. Also, change oil not based on mileage, but based on TIME for the bulk of us 'low mileage' guys.
Best thing you can do for your motor? Use it or loose it, DRIVE it!
