Combines Conklin products good or bad

If Francis uses them and grows 500bpa corn, then it must be a good thing to do! Really I don't know a thing about the products, but it's most likely about like selling seed corn or feed from your farm. If you are a good salesman you can sell anything to anyone. IlNH

We have used their Fertilizer products and they seem very good. The synthetic engine oil products are ok (expensive) however they recommend you change your oil something like every 10,000 miles. We have a neighbor that is a sales person for Conklin and follows their recommendations on oil changes and has to replace his engines about every 70-80000 miles. Personal opinion... stay away from the engine oils but give the other products a try.
