My O'Reilly Auto parts has 5 gallons of 15w-40 oil for $65. It has their name in it. What do you all think about O'Reilly's engine oil?

Don't know if it still is but at one time it was made for them by Valvoline and I have used there oil for decades and never had any problems
BUt.. is it rated for diesel or ignition? If its got the api rating for the service your using it for, it should meet the standards irregardless of who made it. With out knowing its exact properties, I just would NOT run extended changes. For those who do oil samples, can run it till it needs changing for longer intervals.

Look for the API circle, and the viscosity.
It will tell if the oil meets your engine specifications, found in the owners manual.
Very important for late model engines with emissions and high tech variable valve timing, or GDI (gas direct injection).
Old tractors will do just fine on diesel oil or gas oil as long as the viscosity is close. Multigrade is good, but keep the numbers high, no 0, or 5, stay with 10w 40 or 15w 40.
Oreillys doesn't make the oil, they buy it packaged for them. Who knows what the maker actually is, but you can trust it is what it says it is, they would be subject to mega lawsuits for selling something that falls short!

Assuming it's a non-synthetic CK-4 diesel oil, it's probably comparable to Shell Rotella T4, which, when available, isn't that much more expensive at TSC or Wally World. I don't use T4 in my truck, BTW. I stick with semi- or full-synthetic diesel oils.

I know oils are supposed to be the same but I changed oil in my wifes car. Treated it to Mobile 1, consumption doubled. Back to oreily's, back to normal. Conclusion: O'Reilly's oil good, Mobile 1 bad.

We have been using Mobil 1 0-20 for years with very little consumption in our Subaru's.
Almost all modern oils are going to carry the latest API classifications, most others that carry older classifications are single viscosity or specialty type oils. Keep in mind API classifications always supersede older ones. The Oreilly oil carries a dual classification, meaning it passes classifications for gas and diesel engines. Dual classification oils are arguably superior to single class, as they offer better protection and can service multiple engine types.
Omni Specialty Packaging is oil/chemical company that can make, package/bottle and distribute all sorts of chemicals and lubricants for anybody. They more than likely do this for dozens of companies, even in direct competition of each other. They do this for Oreillys and who knows else. BTW I think AZ utilizes STP for the same thing.
