Oil Consumption --> Engines-List message posted by: Mario Nolte Hello Konrad, if I would recognize increasing oil consumption my first reaction would be performing an oil analysis. (And, if its the first one, resent that I cant compare to the outcome of earlier tests) That way upcoming problems are recongizable quite early and can be taken care of before greater damage is done.

Right from Lycoming. When talking to their reps at OSH, they merely dance around the answer, and essentially say "it is designed that way" or "that's the way it is", with no technical info as to why. I was promised some forthcoming (twice), but never received anything. With the vast amount of technological advances today, they insist on living in the past. There may be beaurocratic obstacles in the way, who knows?

Not going to run it till all the oil is gone. As for my 300hp engine, if I were to fill to the 12 qt line the first 4 quarts would get dumped overboard pronto and settle at 8 qts. > Not if you have a 12qt system in that 300hp, and then burn roughly 1qt/hr.?

Good question. Like the O-320/360 series with an 8 quart sump on an engine that works best at 6. ________________________________ Message 8 _____________________________________ Time: 11:05:20 AM PST US From: "Jim Baker" Subject: Re: Engines-List: Oil consumption --> Engines-List message posted by: "Jim Baker" > And then you still have 8hrs. until the seizing of the engine... > > Why do they make it 12qts anyway if it can't hold it in the first place, but pukes oil until its down > to 8qts? I've never seen an engine that didn't have it's own oil-level comfort zone. Some are more, some are less. The 12 qts was ostensibly for oil cooling of the engine, expecting that the greater oil surface area would dissipate more heat through the case walls, oil cooler, and oil pan, from the piston crowns and, marginally, from cylinder barrels. I've seen some that were happy with 9qts, some with 10, and rarely some with 12. Sometimes the same engine model in the same type aircraft had a different quantity level...go figure.

Regarding for instance a Lycoming "O-360 A1A", I understand there is a wide deck and a narrow deck model. Is that the only difference among these engines, or is there something else that might be different among various "O-360 A1A" engines? thank you, skip ________________________________ Message 10 ____________________________________ Time: 04:32:21 PM PST US From: Hopperdhh@aol.com Subject: Re: Engines-List: Max.

Oil Consumption Did not take the time to analyze the formula. Just as given by Lycoming. To the best of my knowledge, this applies to all their piston engines, therefore the 4 would not fit. As far as I am concerned, one quart between oil changes is enough, but have been there before, and have told people how it is done. (albeit against manufacturer and FAA edicts) Nuff said.
