This oil is bottled by Warren Performance out of Nebraska for "Old World Industries". On the bottom of the quart container you'll find a WPP or a WNE for Warren, Nebraska.
IMO...same oil as SuperTech at WM and the Warren brand...Mag1.
I bought a case of this oil, on clearance, at Strauss Auto Parts for $1.79 a quart in SN, GF-5. I bought a 50/50 mixed case of 5W-30 and 5W-20 quarts.....for blending with other oils. (I bought 14 quarts so I could get over the threshold of $25.00 in order to use the $5 off coupon) The actual price per quart was $1.43 for 14 quarts of oil.
IMO...this is good serviceable oil for the price and you can run it, depending on your engine, for 5K to 6K with confidence.
When I get back home to Coney Island, later this month, I'll be using this oil, as well as many other clearance oils from Kmart and stash oils for "a whole Lotta" oil changes for neighbors, family and friends vehicles. This oil should blend well with all name brand oils and store brand oils. After all....it's compatible with all synthetic and conventional oils. It says so right on the container!!!
But for now.....I'm enjoying Florida.
