Which approach would you do?

[PandaBear]

Near free oil: various 5w40 and 0w20 / 5w20 synthetic (Valvoline, Rotella Gas Truck, Pennzoil Platinum), blending Xw20 to 5w40 will make a 5w30 weight oil, good enough for my use in the beater.

Vehicles: Prius, IS250, an oil burning, leaking beater (Integra, Corolla, etc)

Option 1: use the Xw20 in the Prius and IS250, drain the dirty oil on schedule, use fresh 50% blend of Xw20 and 5w40 in the oil burner / leaker and top off with the same blend. Change the oil burner / leaker on schedule and top off with fresh 50% blend.

Option 2: use the Xw20 in the Prius and IS250, drain the dirty oil on schedule, use 50% blend of dirty oil drained from those 2 cars and fresh 5w40 in the oil burner / leaker and change twice as often, top off with this dirty Xw20 and fresh 5w40 blend. This will basically use up all the dirty Xw20 and still keep the oil in the beater fresh enough, fewer waste oil, fewer fresh oil used, fewer trips to dump the oil

Option 3: use the Xw20 in Prius and IS250, drain the dirty oil on schedule, use 5w40 in the beater / leaker as fresh fill, top off with the dirty Xw20 oil drained from the other car.

Thought?

Either options 1 or 3. Too much to keep track of for option 2.

Recycle the used oil to achieve karma for driving known oil burners.

Separate the oil you like from the oil that you dont like.

Use the oil you like in your main vehicles - piece of mind is worth something.


Use the oil you dont like in the beaters- They wont care or know the difference.

If the burner is that bad on oil, then sure, why not reuse the oil in that.

If the oil was near free though then perhaps whatever is easiest is bestest.

Maybe throw some cheap generic 20W-50 in the burner
