"Been There, Milled That"
The Walmart oil, I don't find very thick. but my bars aren't wearing. It seems OK. but it is now $7.50 gallon.
There's a couple Ace HW around, I'll check their prices.....
I find the Poulan oil very inconsistent. I've got some thin stuff and some thick stuff. I thought it was the old tall gallons that were thin, but I've had the newer squat gallon jugs that have been both. I bought it for the Aux oiler and was disappointed that it got thicker.
I used to get Quaker State at Menards, but they don't have it anymore. I thought that was about perfect for flow and tack. But, I've got about 12 gallons or so to go through before I buy any again....unless there's a sale I can't refuse.
