That said I have ONLY used the cheapest NAPA tractor hydro oil in probably 25 or so different 610s for nearly 40 yrs now......reason being that it works great and I don't have a single machine that doesn't leak at least a few drops (I consider it a leak when it sprays the operator ;-)). I have additionally bought machines that the previous owner had been running auto trans fluid with no apparent ill effects. I have not responded to you "power" question due to the fact there are so many possibilities as to what the problem is. In my view, I would start by isolating two different issues. Is it a "engine power" problem or a mechanical "drag" on the engine problem. You mentioned that work had recently been performed on the engine which makes me suspicious. I have had machines that couldn't make it back onto the trailer due to something as simple as a 'timing' issue.</p></blockquote><p></p>
