Winter Oil

[Army]

Whats a good winter weight oil to run in the D14 Gasoline Engine. Middle Of State Of Wisconsin

 

[cornerpost]

IMHO a good multi-weight even a synthetic 5-30. Just
my thoughts not an engineer.

10 w 30 sae with zinc additive
( Quaker State 10 w 30 high mileage has zinc at the higher level) .
Old manual tell how to run in cold weather .
My suggestion is get the manual and see what they say, or maybe someone that has manual will share there story.

I just run 10w30 year round. Works fine.

Oils have changed a lot in 60 plus years. The Operator's manual for a D14 called for SAE 30 above 90 degrees, SAE 20W down to 32 degrees, and SAE10W below 32 degrees. I would say few follow those recommendations anymore. I run 15W/40 diesel oil, year-round in my D14s and do start them, if needed, even below zero. As others have posted, a 10W/30 (with high zinc levels if possible) should be ok. How much do you run it in the winter? Is it stored inside (heated?) or outside? Those things can make a difference.

I use it for plowing in winter. It is stored in a non heated shed which has me leaning to a lighter weight for start up purposes when the weather is below 0.

10w30 in my Iowa tractors starts good with quick oil pressure recovery down to well below zero.

We ran those engines with 10W30 year around back in the 50s and 60s. Started them in unheated sheds every day to haul manure, plow snow, work in the woods. They ran just
fine. That viscosity was recommended by the AC dealer as well as the oil supplier. My recollection is that, when multi-viscosity oils first came out, that was the only
one available.

You dont need zinc additive in farm tractor engines.

 

[J Hamilton]

I have always heard that oil that is high in zinc is better for the older flat tappet engines.

 

[DrAllis]

High zinc in a flat tappet camshaft engine is a very good thing, I believe. Over 1,000 ppm for sure. More is better.

 

[Traditional Farmer]

I run 15W-40 diesel grade oil in all tractors gas and diesel year round,been doing it for years no problem I know of.

 

[DrAllis]

For winter cold starting, even on diesel engines, 10W-30 oil is faaaar superior to 15W-40 for the starter to spin the engine over. And, in many cases, it's adequate for summer useage as well for engines that really aren't worked hard. I know. There are those who refuse to believe it, but it's true.

 

[dhermesc]

Zinc is only needed if you have very high tension valve springs - like some 1960s performance engines. When the D14 came out I don't think zinc was even part of any additive package of any motor oil on the market. Most of those tractors were probably running nondetergent 30 weight or 20 weight (winter). Any current quality 10W30 oil would be many times better than what that tractor had in the crank case when it was new.


I would use 10W30 or 10W40 in it unless you have an abundance of 15W40 on hand.

10W-30 all year works for me.
