I have never owned an engine that burned one brand of oil and mysteriously quit because I poured in another brand. Personally, I cannot envision a motor oil that is the so called "magic bullet".
Oil burning is mostly contributed to worn rings and or valve guide seals. No oil on earth, repairs worn parts.
Any of the oils you mentioned are quality products. I put Deere branded oil in my new tractor just to make sure no warranty issues arise. The fat guy at the Deere parts counter plainly told me that Shell (Rotella) bottles Deere oil...but of course, JD oil is superior to Rotella. I say BS! I wouldn"t be a bit surprised to learn Shell bottles Case/IH oil too.
Regardless of who bottles the oil, if it is a quality product from a major producer, you will be well served. Rotella and Delo are excellent diesel oils and lubes a gas motor just as well.
In 30+ years of operating all sorts of equipment and vehicles, I have NEVER had an oil related engine failure....ever! I think folks are absolutely nuts about this subject and every week, a new thread is started on the subject.
I also think people change their oil too danged often...scared to death some gremlin is going to destroy their engine. They harp...oh, it"s just good preventive maintenance. I agree...you should change your oil. 7500 miles is often enough in a vehicle and if you use synthetic...15,000 is about right. In most farm tractors, once a year is fine. If you are running a row crop operation and tilling 5,000+ acres, change it every 100-200 hours. If you have to add a quart here and there, so be it. 200 hours isn"t very long if you are working a tractor everyday.
Consider oil a consumable. It isn"t magic in a can. Machinery wears...even if it is properly lubed, just a fact of life.
Have any of you ever referred to 1950"s IH owner"s manual? They plainly state in there, that just because oil turns black, doesn"t mean it"s bad. That, the carbon suspended in the oil is a lubricant in itself. The oils on the market today are light years ahead of what they had 50 years ago.
WalMart doesn"t own a refinery (yet!) and whatever they sell, is refined by some major producer and squirted in a bottle with their label on it. I know a man who has 240,000 miles on his Chevy truck and it has never had anything but walmart oil in it. It is obviously a quality product. Why is it cheaper to buy? Not because they leave out secret ingredients, but because they don"t have millions in advertising to recoup. I have a friend that worked in a Shell refinery in Oklahoma. He said they bottled oil for many, many different retailers. It all came from the same source...just different labels on the bottles.
So, choose your brand..if you feel better paying $3.50 a quart instead of $2.50, go for it. I apy $5+ for synthetic and change my car oil once a year. At 134,000 miles on the Pontiac, 114,000 on the Dodge pickup and 180,000 on the toyota pickup, I"ve yet to have any problems. That"s called empirical evidence...seeing is believing. The old Super A gets whatever is on sale and the new Deere gets JD oil until the warranty expires. Then, it"ll get a diesel rated synthetic.
Now, call me a fool and continue doing what works for you. That"s all that matters anyway.
