So your issue was oil related?Good point. Damit. I'll be quiet now!
BTW It was more of a breather issue, too much crank pressure.
As a general rule I'm very lax on oil changes. I've owned a number of cars that only saw the oil topped up and never changed. I don't really believe "good" oil makes any difference, just have enough.
The only engine failure (spun a crank bearing) I've had was because I was pushing very hard and was down a quart or two.
