What weight of oil for winter use.

Derrick In NY · Dec 18, 2009

I was wondering what the recommended weight of oil is for use in a Super A during the winter and also what weight oil should be used in the air cleaner during the winter as well.
Thanks. Derrick

I run 15-40 year round in my 3 Cubs air cleaner too.
Never had a problem with them starting. I only use one in the winter to haul a little wood but once a month I start them all and run for at least a half hour to warm them up.

Derrick -

I use 15W40 both in the crankcases and air cleaners on my SH, SM and Minnie Mo U year round.

All start fine down to 0 deg. (Colder than that it doesn't matter - I don't want to be out running them anyway...!)

Bob, What are your thoughts about using 15W-40 diesel engine oil in these old letter series Farmalls? I've seen a little "chat" about it here on the forum but little from the folks like yourself, Rustyfarmall, CNKS, migraine or glennster on the subject. I believe I read somewhere the diesel grade engine oils contain some elements like zinc (maybe others) which have been removed from the gasoline automobile oils. Would be very interested in your thoughts on the subject, Hal.
Hope you and Glenda and the rest of the family have a wonderful Christmas and New Year. I trust you are probably doing your yearly help with the Christmas tree farm and using your tractor a little in the snow. Happy Holidays, Hal..

I've had to get my 340 running at 10 below before so I run 10w-30 in the winter. 15w-40 in the summer.

The zinc is only an issue with a high performance engine during break in. Oil designed for diesel engines is usually very high in sulfated ash, usually twice the amount of "low ash" gas engine oil.

Considering the fact that most of the letter tractors were built when nondeterginated oils were the norm you could pretty much use anything off the shelf at Walmart and it would still be better than what was poured into them in 1950.

I use 15W40, and stay out of the low ash and high octane gas arguments.

Farmallhal · Dec 18, 2009

Charles, what kind of 15W40 do you use? Is it rated for gasoline or diesel engines? Have a great Christmas out there in western Kansas and hope the snow don't get ya to much. Your comments are always appreciated, Hal.

Shell Rotella T, it meets both gas and diesel specs. Merry Christmas to you too. It doesn't usually snow much out here, but anything can happen. Had about 3 inches last week.

Derrick you have asked one of the more lively questions on this board. The only question you could ask and get more answers on is what spark plug to use.

I am pretty much an old fashioned guy, and I use HD 30 in the summer, and hd 10 in the winter. However, any of the previous posts are also good suggestions. And since I keep my Cub in a heated garage, I just use HD 30 year round (I use the Cub for snow plowing). My other tractors are not in heated buildings, so they get the HD10 in the winter. For ones that don't get used in the winter time (ie. show tractors), I don't even make the change.

Multivis oil is fine, and unless you are really working them hard, I don't see why a 10w30 wouldn't be a good choice.
