quick oil question

[dgjks6 6]

Hope this is not been asked a zillion times, but I just got a plow and instead of storing the tractor this winter I am going to plow. I use regular 30W oil. Do I need to switch for the winter oil change. I am going to go with synthetic - but should I use a 10w30 or a 5w30?

ok...5w-30 is your best bet. I do not use a full synthetic due to my newest tractor being 14 years old. seals and gaskets get conditioned using fossil oil (dyno oil). when you switch to a full synthetic it want to recondition your old seals and typically this is a bad thing in old tractors.

with that said I use castrol GTX synthetic blend 5w-30 all year around in all of my tractors...even my 1970 electro 12 and I have zero leaks. you have a better viscosity index with the GTX syn winter blend for better all around performance and lubrication.

most engine manufacturers tell people not to switch to a synthetic oil until they have 20,000 miles on an automobile engine (duramax diesel). I actually switched at 22,000 miles in my truck.

so I guess my recomendation as a certified lubrication specialist would be to go with the syn blend 5w-30.

Yep, oil sure can raise some interesting opinions and points. Then

it depends if the engine is splash lubed or oil pump lubed. I like

synthetics myself.
