I agree with Charley… I did that for a while but it was inconvenient, and once I found a proper oil it was pointless.

Consider, if you have to top off your oil by adding a quart between changes (as is common), are you also adding the exact proportional amount of your additive? It’s just impractical to deal with on a regular basis. There is nothing magical about Castrol 20W50.

I didn’t see anyone include a discussion of the practice of adding ZDDP to oil that is lacking in it.  There are several sources where it is available and I have availed myself of it and added it to my  Castrol 20-50 when I change the oil in my 80 MGBLE.
