A buddy gave me his straggler his straggler qts of oil and I ran it 6 mo in my FORMULA last summer 2020(MAY through OCT) ~ 1500 mi. Engine ran unbelievably smooth all summer. Then I changed to RGT 5w30 prior to winter storage in which I haven't pulled the car out yet for the season.

Not that I make this a practice anymore as I once did about 45+ yrs ago when money was tight. However, I'll do it now and again with more compatible oils that I have laying around from our own vehicles. And not that I believe that this is an optimal way of doing an OCI but, I also don't think it hurts anything and I have my own proof of this. Lots of it!

In my distant past, I've used 5-6 different grades of oil, each being a different brand as well and my engines(placebo) seemed to run better/smoother/stronger than with the required/recommended oils.

I keep an empty 5qt jug and dump the extra oil in it after all the oil changes I do where the sump doesn't quite take 5 quarts. Mostly 0w20, 5w20 and even a small amount of 5w30. Various brands, mostly full synthetic and some high mileage blends. When the jug gets full, it goes into the car that needs an oil change next whether that be the Van or the Mazda. Last time it went in the Mazda. No issues and the car ran great.
