There has been a lot of discussion here about HyGuard. I asked the very same question you did. For what its worth, there are other quality brands out there sold at other dealerships like New Holland, Massey Ferguson & Kubota. I was going to buy my HYGuard from New Holland who has convinced me that my JD would not get a tummy ache on New Holland's formula & that it was 100% compatable.
However, as stated here in this thread, it is better in this case to stick with the JD stuff which is what I did in the end as well. However I fully undersand your asking because I too find the prices at the JD dealer to be freaking out of line insane. That dealer who is charging you $25. a gallon should really explain that to you. Im down here in SC & the local thief I go to charged me $18. per gallon. There can't be that much of a regional difference in price???? Maybe next time you & I should ask our respective dealers to give us at least one kiss before he sc..w's us.
