Fair point.
The gain is a relative thing.
Per the store's "lifetime guarantee even on oils" policy you buy oil from them, use it, then return it used in its original container and get credit for a new one. Discussed above (even if still not understood by a few, judging by some comments

).
In my calculations, it ends up getting me a $55 jug of 5qts for $10ish (in winter when I don't do my oil change myself) + the hassle to drive to the store (which is nil, as the only Aldi in my area is there and I need to go there every now and then).
In summer I'll do my oil changes myself and recover my own used oil, so I won't need all these gymnastics, and the jug of new oil will cost me just the drive and the hassle.
Indeed. But I bought that car new in September and it has been fed on Motul exclusively after the first 1500 miles. So I want to keep the streak for the first year or two and have some oil analysis done. Eventually I'll probably just switch to Valvoline Restore and Protect (see what I did here

), unless the Motul turns out to be magic (which it is not). I am just partial to Motul, I used it in my youth back in Europe.
That solves it. Let's lock the thread. I already have returned oil to them that has been mixed in a common recovery container with the other oils I drained from my other cars, I'll have to atone for that too.
