In term's of cold weather performance, think of regular Hygard as a 15w-40 oil and LV Hygard as a 5-40. Which one do you think is going to perform better in frigid temperature's?
The other part of my logic on going with the regular Hygard (besides the fact that I won't be operating in below zero temps much, if at all) is that 99% of my operating is running the tractor in the summertime, wide open, mowing in 80 degree heat.
Since I only put, maybe, 80 hours or so a year on the machine, I elected to pick the hydro oil that seems best for the majority of the time I'm operating.
If I put 99% of my hours on the machine when it was cold, I would definitely go with the low-vis Hygard. You can definitely feel (and hear) the difference when it's cold (say, below about 40 degrees). When I do use the machine in colder weather, I always let it warm up for 5 minutes or so before I do much with it.
