winter oil additives
hi all. anyone ever use an additive for winter use? i have read all this stuff on differnt additives that helps prevent wear on startup but im always skeptical of such things.
anyway,what oil do use in winter? i have 78 f-250 400cid,with plenty of miles,still is running strong but anything i can do to treat it nice is what im trying to do. thanx

You don't need to add any winter additives. I would use a 5W-30 in your engine. The W stands for Winter, not Weight. We happen to have about the same climate here. If the temperature drops to -20 F you can throw in a quart of ATF.

I once used Rislone Winter Start, but have no idea if it did anything worthwhile.
If I lived in Montana I would be using a synthetic 5w30 or 0w30 for winter.
As far as I know, AFT is not recommended to be put in the engine crankcase. But then in the old days they would put 10% kerosene in the crankcase for extreme cold to keep the oil from solidifying.

Yeah... ya know... I've got a few old fords, and I am by far not an expert, but there are a few old (and cheap) tricks you can use. The ATF works, I've used it, I know it works. I know it is a little warmer down here, but still pretty close. The ATF is kind of an emergency thing, if I were you, I would carry a can of Sea Foam, and when it gets cold, dump that in the crankcase.
They do make warm weather grades, they call em straight weights, starting at 20 all the way up to 90 weight oils. I wouldn't recommend it, since the multigrades are way easier to find, and generally cheaper.

I might suggest a block heater or a light bulb under the oil pan on those cold days and nights. Easy to do at home....maybe difficult at work.
How cold we talking here? Oils like Mobil 1 0w30 for example has a pour point of -54*c.
Chevron 5w30 synthetic has a pour point of -52*c
I realize the pour point isnt a safe crank temp. I would think it safe to say -20 or 30*c would be safe. I've had a dino 10w30 in the -20*f temps my car saw for a few days without a noticable problem. Car ran 238,000 miles before I parked it. Engine was fine for 238k miles....car was done.

Say you changed the oil a month ago with 10w-30 and that +2F cold snap comes through . It can help get you by till next change .
You can use it if you like to stock up on one oil for all seasons but mostly with warmer months in mind .
Mystik HD 30wt is just 22 bucks for a 5 gallon pail ya know !
