I wish I'd seen that sale. My F-250 uses around 5 gallons, and I've decided to run T6 as long as it's available and I can afford it. Needless to say I don't change that one based on time intervals, I'd be dumping out practically new oil.like Rotella T6 synthetic for ~$10 a jug, etc.
I have some like that. I use it for cutting oil when drilling metal. Or little jobs, as mentioned, like door hinges, casters, etc.Guess the 3 gallons of 30w that I got from my grandpas estate in paper cans might be no good???
I’m gonna keep using it.
That's also a very different situation than oil in a sealed bottle.Well there is a reason why they say change your oil every 3,000 miles or every 3 months. Water will get in the oil from sitting in the engine.
In this video they discuss oil change intervals and how the 7,500 - 10,000 mile is bad. They discuss a lot more than just oil like a gapless second compression ring for diesels.
I'm not where I can watch that, but I can guess as to what it's about from the titleWell there is a reason why they say change your oil every 3,000 miles or every 3 months. Water will get in the oil from sitting in the engine.

Motor oil isn't hygroscopic or hydrophilic. It won't absorb moisture from the air or mix with it. Moisture could condense and collect inside of an open bottle, but it isn't going to mix with the oil. It's going to do its best to separate from water. If any water collected in a bottle of oil, it'll be in the bottom with the oil riding on top. The only reason water mixes with oil in the crank case is the blending action of the crankshaft. That's why you end up with a milkshake when a head gasket blows, air and water in the cranks case bets blended into the oil creating the milky appearance.If it is opened I would assume it could absorb moisture over time. I don't worry about those things over here because it isn't humid here. You would have to leave the lid off of the bottle for anything to absorb enough moisture to matter, with the exception being the possibility of condensation during the winter.
