Nothing wrong with using Agco products, they are of good quality.
There is far too much obsession, and hysteria, over fear of the warranty reaper.
One would think there are threads all over TBN, about how someone's warranty was denied, for some silly reason. Except, there aren't.
If you use products in your tractor, that meet the requirements in the owners manual, they cannot by law, deny your warranty claim.
They would be foolish to even try that, now that the internet would spread that news instantly, creating a P.R. headache.
If you have an oil related failure, it will be a catastrophic failure. That only happens during the warranty period, from a serious manufacturing defect. And, as long as I have been on here, there have been very, very, few.
There isn't much to debate when this happens. And, they probably will already know about the defect, and have a silent recall for it.
Yes, use approved fluids, and filters. Sure, keep records, and the receipts. If for no other reason, to show a future prospective buyer, you maintained it properly. Then, relax.
Don't fear the warranty reaper. :dance1:
