As the title states.
Walgreens has the Formula Shell Conventional Motor oil on sale this month for $5 for 5 quarts.
You must buy 5 quarts at once, and there is a mail in rebate of $5.
I ended up buying 20 quarts, for $2 each, then did 4 mail in rebates to 4 different addresses. Comes to $1 per quart.
3 grades available. 5w30, 10w30, and 10w40.
The walgreens in lockport on south transit is totally cleaned out, only has 10w40 left. I bought all the 5w30 at the walgreens on transit in east amherst.
