Down to my last 2 gallons of Pennzoil 15w-40 "Long Life". Acquired about 10 cases (40gal) for around .50/gal from a company I worked for that went bankrupt as we were clearing out the shops. We used to keep a couple of jugs in the trucks to top-up standby generators in various building we owned. Oil is probably around 15 y/o and predates the Shell takeover, but appears perfect when I pour it. I have been using it for years in my Honda and Yamaha bikes and the old '93 Buick. I really like the "Fun-L-Flo" jugs!
