Quick question about oil changes
I have 2015 Winnie on E350 chassis. We live in southern California and only use our RV 2-3 times a year. We drive a total of less than 500 miles a year. Question is: is it ok to replace oil every 3...

Condensation is not a rumor. Once you take the oil out of the bottle the moisture in the air gets in it.
Just a question mind you. IF the oil is sealed in the engine, with no leaks, and no way to get air in. Does it still condensate?
The engine is not sealed. Its exposed to atmospheric conditions through the engine oil drain holes and some other places. Engines inhale and exhale every day with the changes in temperature, and when it goes below the dew point, condensate forms on the metal which contributes to rust. When the air cools(contracts), it inhales, and when it warms(expands) it exhales. The other thing that happens is the oxygen in the air starts to combine with the oil in a process called oxidation, which changes the properties of the oil in a bad way. When the engine runs, it makes a gallon of water for every gallon of fuel it burns. It's real apparent at startup when the engine is cold, and you see water coming out the tailpipe. The oil is really under attack from a lot of different directions. What it wants to do is form rust and sludge, the two big enemies of our engines.
