(quoted from post at 12:14:18 12/27/11) I have a 2N Ford and I was planning on using 30W for my tractor this winter in Michigan. Will this hurt the engine in any way or will it just make it start harder.

30 weight oil at zero degrees will just barely flow out of the can it came in. You be the judge, but if that tractor were mine, it would be using 10w-30, or even better would be 15w-40.

Thanks Rusty. I appreciate your response on the oil weight.

I would use 10W-30 if it is going to sit outside in the winter, otherwise use 15W40 year round.

It's a gas engine. I'd use 10W-30, 15W-40 is more a diesel oil.

Agreed.

Unless the engine is worn out 10W30 will give it all the protection it needs year around.

Run 10W-30 if you need to be able to start your tractor in sub-zero weather. Speaking from experience.

Would adding some slick 50 help?

...and yes, that is a question.

Even down in So. Texas in growing up, when single viscosity oil was all that you could get, 20W in winter months and 30W the rest of the year. On that tractor agree with the multi vis 10W-30.

Do a test on 10/30 and 15/40 oil samples in the freezer.Tell us what you see.

I think slick 50 is good in any motor, anytime, not just for winter.

may be but the company that sells a big portion of it calls it "all fleet" as it is good for all of the vehicles in your fleet including MIL's.

Tried running 30w in my 9n once when I was first getting it going. One cold winter day it started just fine but it blew oil out the filter cover seal. Having no thinner oil at the moment I added diesel fuel to thin it. (I don't recommend this, I just needed that day) It took 3quarts of diesel to get it thin enough. I recommend 10w-30 or 10w-40.

I have went to 10W in the winter, but didn't do any thing else but feed a few bales hay. Doubt if the oil ever got hot. Keep eye on oil pressure and it was always fine.

I have over 15 engines I maintain...3.5hp lawn mower to 200hp V6 GMC pickup and everything in between(autos, tractors, crawler loader, mowers, etc.) Got tired of keeping 4 different grades of oil in the shop for them, so I got a 55gal barrel of Rotella 15-40. I have been using it in everything I have year round for over 10 years with no adverse effects. One size fits all.

To throw another hat in the ring and confuse things even further:

For gas tractors I've always been told to use straight SAE 10 in the winter and straight SAE 30 in the summer.

If you are operating tractors in sub zero F temperatures, you really should have water and oil heaters on them. Even a multi viscosity oil
gets thick and won't pump at those temps. I don't know how equipment ever ran back in the 30's,40's,50's and 60's with those unadditized straight weight oils. Heck most of the old Farmalls ought to be junk by now if viscosity was such a big issue. LOL
