Looking for help! Bought new tractor this past Dec 20th for snow removal at my vacation camp in Tug Hill NY. Summer time will probably not see much use. Tractor had 1.5hrs at purchace and now has 10.5hrs being 70% operated full throttle at*PTO*speed for snowblower usage. I would like to wait till at Least 50hrs of operation prior to 1st oil change but that may take over 2yrs. At the same time I would love to run a thinner oil for extreme cold temps we get. I did have a hard to starting it at 0 deg. cranking over slowly. I cannot use a block heater as I drive 5hrs to get to camp and need to open driveway to get to camp ASAP. Would like to run 0w40 synthetic but worried engine is not broken in enough. Would love to hear your thoughts!
