Synthetic fluids

[JLC]

Does synthetics in the hydro's, motors, cutter deck gear boxes, etc? I just wondered if this makes any noticable difference in power. Trying to eek as much out of my 25 horse Turf Tiger as possible.

Usually the difference is a reduction in friction. While this may increase hp a small amount the most noticeable change is lower operating temperatures, an increase in oil pressure to the vital engine componets and increased longevity of parts.

My 5.0 F-150 had a 5 lb. increase in oil pressure and a 10 degree decrease in coolant temps after switching to Mobil1.
