    Hello all.... I have a 04 F-350 w/ 6.0 Diesel..... what type of oil should i use for the winter.... over the summer i have been using 15W-40 Rotella ..... what do i use for the winter months .. 10W-30 ?? Should i use Mobile one or Shell brand... does it matter ?? Do any of you put in synthetic oil in your diesel? I was thinking of using a synthetic but that could get pricey to do that, is it necessary? Also should i add an addiative to my diesel fuel just to be safe in the winter months? thanks :drinkup:

    i use rotella 15-40 they say the cold pour point is only a 4 degree difference.if you can find 10-30 rotella then buy it if not the 15-40 is good .i feel its better to change your regular oil at 3000 miles than use synthetic oil and change it at 5000 miles. when the temps get below 25 degrees go to wally world and buy the fuel anti gell it's cheaper there. i have never had a truck gell up yet. don't forget where you are the service station have to put stuff in it or it would freeze up in the pump .

    Use oils that are API service rated CI-4. You should use Motorcraft Super Duty 15W-40 or 10W-30 only if it meets Ford specification WSS-M2C171-D.

    Ford recommends 10w-30 for the cold weather.
    I read somewhere that they actually ship them from the dealer with 10W-30 installed.

    You can not use regular oil in a diesel, because the diesel rated oils have additives in place to keep the soot from clumping together and causing damage.

    Make sure that your oil has an api rating for S (spark Ignition) and C (combustion Ignition).

    Check out your owners manual and also do a little research online about oil for diesel.
    This web page might help.

    Since this is the Ford section I will assume most diesels are Powerstrokes, either 7.3, or 6.0. In this case Mobil one is not a recomended synthetic oil for any diesel engine with HEUI injectors. This includes several Cat HEUI engines as well as the Powerstrokes. This is per Mobil, they recomend Mobil Delvac 1 as the Synthetic oil For these engines. Mobil 1 can be used in the Ford IDI diesels. I run Delvac 1 in my truck and I am very happy. In the winter it cranks over just as fast without the block heater and Delvac 1 as it used to with the block heater and dyno oil.

    Tom, I live in your area.I just picked up rotella 10W30 from menards of all places for $6.00 a gallon for my 6.0 diesel.If you don't leave town and have access to pluging it in the 15W40 will work fine.I switch to 10W30(if I can find it)or 5W40 synthetic because I also go way north snowmobiling and can't always get to a plug for the block heater.Also power sevice makes a good anti-gell fuel conditioner.Get the stuff in the white bottles.I use it only when it gets real cold around here and every time when I go up north because you never know what kind of fuel your going to get!

    It would probaly be wise to use 10w30 if you can find it just in case you cannot plug it in sometime even if you normally do.

    The first number is the pour point and the lower the number the better it will start in the cold wheater.In the winter I use a 0w40 from Esso and I haven't plug it in since the day I got it .Just make sure it is rated for diesel engine

    I take it that this is Synthetic. What does it cost you?

    I won't tell you what oil to use. I WILL tell you that I use Delvac 15W40 year round and I have over 200K on my 7.3 PSD. Sometimes I use Shell Rotella but always stay with the 15W40. No problems. No hesitation on startup even in cold weather.

    the majority of people never switch.but you need the relize we are talking about the 6.0 which seems to be more finicky about oil than the 7.3 is.

    The 6.0's are very temperamental when it comes to the type/viscosity of the oil. The API rating is a very important issue. A CI-4 rating is recommended, but actually a CI-4 Plus is the newest one out. Just make sure that when you fill the crankcase back up, that you keep the oil level in the middle of add and full on the dipstick.

    I had not heard that one before.
    What's the reason for not filling it to the full mark?
    And also should I be doing that on my 2001 7.3?

    Just wondering.

    Mebes -

    No, just applies to the 6.0 diesel. Some owners are dropping the level as a fix for rough/rolling/surging idle/running conditions.

    Good job Mebes. There is no perfect oil for all temps and if temps get to and below zero a lot with a diesel you need to have a lighter oil in it if you want it to be able to start more reliably with no heat.

    Hello Tom, coincidentally I was in Geneva last night for the X-mas walk. I realize this may be a little bit of a drive for you but you can get Delvac 1 in Huntley,and in Sycamore @ Farm and Fleet. You might try the New Holland dealer just north of North Av.(rt.64) on Randall Rd. You can also try the truck stops at the Hampshire I90 exit. Buck Bros. John Deere at 47/72/20. or as a last resort look in the yellow pages under oil distributors. But to answer your question I would go by the API rating. I do not personally know of anybody who is using that oil in a PSD. Probably because it is not a true synhetic, but a synth/blend.
    Good luck Gregg
