What oil are you running in your gas tractors

My son and I have been arguing about what is the best oil weight and brand to run in our gas AC tractors (B up thru a 180G). I was wondering what everyone's opinions were and what they were running. I know this has been discussed before, but I wanted a new post with unbiased opinions to let him see what everyone is running.

Thanks,
Tim

Any detergent oil, personally, I prefer multi weight.

Allis B, IB, Low B, G, D10, JD M, 8KCAB, C152

Rotella 15w40

Just an old country boy saved by the grace of God.

Rotella 10/30 as I use tractor in the winter some.

If you start any of your old tractors in cold weather, Mobil 1 Turbo Diesel 5w-40 would also be a good choice. It is also rated for gas engine use.

Im with Dave... 10 w 30 detergent oil ... Wal Mart brand in all my smaller tractors. Use Mobil 5 w 20 in the trucks and SUV.

Like them all, but love the "B"s.

the caseih low ash oil for gas tractors is about the best. the rest of the oils are great but gas tractors are kind of a breed of there own.

AC from the start of my families farming career till the end!

I use 10w30 in my gas engines for years and 15w40 Rotella in my diesels

Amsoil 10W30 full synthetic with Napa Gold filters. Use mine year round.

The oil I add to my tractors has alot to do with which part is leaking. Lately I have had to add alot of hydraulic oil but I just got the power steering fixed so it should just be time to change the 10 w 30 motor oil. Someone told me a long time ago the old gas motors where designed for 30 weight and that was what you should run. Never seemed to be a seasonal issue running 30 weight in the d17 year round here. It has run on that since the 60s when my grandfather bought it and the 226 is still running great. That is one well built motor.

Original manual for all my old tractors (which are gas) say 10W winter and 30W summer so I also run modern conventional 10W-30. I don't run synthetic. I don't think these old engines were designed with close enough specs to really benefit from it over conventional.

I know it's picky, but there is no 30w oil-----------------the "w" after an oil viscosity denotes that it meets the winter specifications for that viscosity. These specifications stop at 25 weight oils. Wink

Actually, when new, some of the engines probably did have as tight of clearances as today's engines. It's just that some also had looser clearances than today's engines as machining tolerances were not as well controlled back then.

Even the worst modern oil is better than what was available back in the day. Change the oil and change it often.

1957 WD45 dad's first AC

1968 one-seventy

1956 F40 Ferguson

From the old old school.

That is when we sold them new in the 30's to the 60's.

In the engine we used sae 30 non detergent oil. At that time we did not have detergent oils available. In fact, when we had customers who bought used tractors they started using the most modern detergent oil available. Worked too good since it cleaned out all the gunk that was keeping the engine from burning oil and leaking.

We would go out with five gallons of our sae 30 oil and change the oil. It worked and the owner got quite a bit more life out of the unit before a major overhaul.

In the hydraulic we used sae 20 NON DETERGENT oil - 10 NON DETERGENT in really cold weather. Some of our customers used detergent oil and they ended up with a case full of foam.

That was how it was in my olden days.

Now I am delighted to hear the excellent results from the newer oils in both the engine and hydraulics.

Good Luck!

a note on oil - Al Gore and is minions have impacted oil. The newest oil for the tier IV is not a "premium oil" . Our resident engineer did some research - the IV diesel oil has had a lot of ingredients that "pollute " when consumed, removed. They charge us more for less. The latest oil is fine I am sure, but is developed not for lubrication , but to pollute less when "used" by the engine. Also automotive oil several years ago had some selenium compounds removed as all cars use roller tappets. This automotive oil will wear out flat tappet lawn mower and tractor engines. Use appropriate Briggs, Kohler oil in mowers or diesel oil. Use the same oil in gas tractors as you use in the diesel.

When told "it's not the money,it's the principle", remember, it's always the money..

Thanks everyone for making my point to my son, I have been running Rotella 15-40 for years in all my tractors, gas or diesel and he was trying to tell me it was to thick for the gas tractors. Thanks again
