So I was sent the wrong oil for an Amazon order last year. Was shipped Opti oil, I have an EFI. This is the Mercury "Synthetic Blend" stuff.
I bought (2) 2.5 gallon jugs. One jug is unopened; I used about a gallon out of the other.
I will let go for $50 firm for both jugs firm, local pickup only (west side of Cincinnati). I will not ship, so please don't ask.
I fish Tanners and Brookville, maybe we can meet there.
