In an article about the longevity of cylinders in aircraft applications the author claims that engines that use little to no oil aren't letting enough oil into the ring step area of the cylinder, causing a significant reduction in cylinder longevity. (In case you aren't familiar with aviation-speak, "TBO" means time between overhaul. Many general aviation engines go between 1200 and 2000 hours of operation between overhauls, and most OCIs are 50 hours of operation.) The author asserts that unless your engine is using a quart of oil every 20 hours you aren't getting good lubrication of the ring step area. To put this is automotive terms, you'd need to be using a quart every 1,000 miles or so. Now, I've never had a car that guzzled oil that quickly. In fact, my current cars use no oil during 7,500 mile OCIs. One has 45,000 miles on it and the other has 92,000 miles on it. So, from my experience in the automotive world this author's theory sounds like bunk. Is there something special about aircraft applications that would make this author's theory valid?
