Actually, the Valvoline 5Qt jugs at my local WMT do have a Walmart logo on them (with a blurb about recycling used oil at Walmart T&L locations.)
But I have not seen it on the Mobil 1 jugs.
Mobil doesn't sell oil in 1 gal jugs. They're 5 quarts.
Sure they do...just saw some at my local Oreilly's last week. I remember thinking...why would I buy a gallon for the same price I can get the 5qt jug from Walmart?
They have jugs filled with custom amounts to get around their "price matching" ads. Around here, I've seen 3.78L, 4L, 4.4L, 5L, 4.73L jugs. Each chain gets a different jug.
Yeah its interesting isn't it, I used my last jug on my fathers Santa Fe...takes 4.98qts no problem swallowing the jug. Theres no need to really change the brand I been using- but I been looking into other brands.
