Will the truck stops take 10 gallons of used oil at a time? I think Walmart and most of the auto parts stores will only take a gallon or so at a time.
I’ve only been refused once, at the TA near home, after dumping there many times. Guy was being a jerk, I left it outside the garage door, especially for him. I recently had about 30-40 gallons, stored in an old parts p/u truck I own. Took it to Oreillys, ( they made me take the empty jugs. I hit a couple Autozones near my house. Both had 4-5 gallon limits( per day). Lastly I tried NAPA, by the house. They have a big self serve tank out back. Unlocked during business hours, sometimes they forget to lock it. No limit, Dumpster for jugs nearby. Tomorrow I’ll be making a trip. My 10 gallons, and some Morons 10 gallons that was left underneath our Trailer ( Shop ) at the yard. I usually dump it myself in the pit at T/A. Sometimes they just say leave it, we’ll get it.
That’s a good point, too many times I’ve had to tell them to pre fill filters, Hit the cross fork fittings, fifth wheel fittings, steering column u joints. I’m Training them. They should be paying Me!! A Good Shop is worth the extra charge. You get what you pay for, sometimes. I once saw a Guy unscrew the filler cap, completely on a brand new 600 Cummins Signature. First oil change, dropped the nut and washer into the pan. TA in Sawyer Mi. They told the Guy not to worry. He worried alright, waiting till Monday, for a new pan gasket. A good Shop is worth paying for. I don’t expect anyone to work for free. I don’t.
Good old Rotella or Delvac every 15-20k tops. Cheap insurance, no matter what you pay. I’m currently a little past 20k, but was staying busy. Plan on 15k. No sludge ever that way.
This is an excellent point. The good mechanic is looking for something wrong with your truck while he is under it changing the oil and greasing it. That something wrong is much easier and cheaper to fix while it is in the shop than on the side of the road later. While it isn’t convenient for everyone to do, I have my oil changed every 90 days by the same mechanic doing my DOT inspection. It costs very little extra in labor vs them only doing the DOT inspection. My carrier requires the inspection every 90 days vs every year, but I am ok with it as it works good for me. I have bypass oil filtration, sample every oil change and run very low miles so 90 days is generally very close to my recommended oil change intervals.
On my truck, I just reset its odometer every oil change and once it gets past 10000 miles I get the oil changed,averages about once a month..
