Hey Bob... I'm just outside Chicago. I know all you good 'ol boys use NAPA, but up here I avoid them like WM. Case in point; when I was in NOLA and preparing for an oil change, I went to NAPA for 30 gallons in buckets, only to get back to the boat, 20 miles (?) with 15W40. I guess JAMAL couldnt read the label. Mea Culpa for not DOUBLE CHECKING before I left !! That was an 80 mile trip before I was done, and ended up getting a much better deal from the Donaldson Filter guy in NOLA, just down the street, who, BTW, had the oil AND all the filters I needed.
My oil guy did have to call his distributor to order it and it took about 4 days to get here. Try dealing with an equipment / truck supply place. Ricky Bobby runs Quaker State anyway (YUCK). LOL
When I did get the stuff, I had ordered 42 gallons for a 24 gallon change, just to make sure I had enough for my trip in case the 12s starting blowing through the stuff. As it turns out, I was using a quart a day until I started keeping it a gallon low on the stick. Now I RARELY have to add. Hmm.
FWIW, my 12s dont smoke and BARELY leak a drop --- I guess I'm lucky, or fortunate.
As far as SAMS here, they only have Rotella 15W40, and looked at me like I was from YERANUS when I asked them about straight 40. I guess BRENT runs some exotic syntho shit in his nitrosed Yamaguchi, but he can recite speaker impedance on his ghetto blaster. EXCELLENT, DUDE !!! Trust the parts guy with WHITE HAIR !!! ws
