10w-30 oil in a diesel

[powpow]

I have an 02 7.3 ford,,,,,90k miles on it

heading to tog and there is no place to plug my truck in

I always run 15w-40 rotella, but my truck ususally sits in the winter and only gets used on trips out west.

Was thinking about running 10w-30 rotella for the trip for easier starting for the trip

What do you think?

I wouldn't run 10- 30 in my truck. I think there is 0 w 40 sythetic that is diesel rated. That's what I would try.

Shouldn't need to plug it in unless it's going to be bone chilling cold. Generally not the case this time of year out there. If you are at the lodge/cabins there are outdoor plug in's on the cabins and near the sign out front if you must feel the need for it.

I used to run 10-30 in my 6.0 in the winter because I never plugged it in very often and it makes a huge difference in starting. The manual states you can do this as long as you aren't pulling at max gvwr. For 2000 miles or whatever it is you will be fine with 10-30 for that oil change.

The only occasion my 6.0 didn't start with 15-40 was this year and it was below 0 for a few days.

Here in interior Alaska, I run Rotella synthetic 5-40 year round in my cummins. It will start no problem at -30F if i forget to plug it in.

Another vote for the 5-40...You want to drop the bottom number, not the top. You will still have the protection of the 40wt when running down the highway, but the pour point of the 5wt on a cold start up. I too believe I have seen a 0-40 for the desiels. That would be even better if worried about getting it started with no 110v power.

Another option, is to bring a small generator with you and plug it in a couple hours before you need to start it!

I have a friend who is a Ford tech and a couple years ago he said that Ford had a bulletin recommending 10w30 in the winter for hard starting problems. I ran Delo 400 15w40 in the summer and 10w30 in the winter in my 2000 7.3 and never had any problems. It starts much easier with 10w30 when it's really cold out.

another vote for 5-40 syn. Works flawlessly here in CO all winter.

I have a 99 powerstroke and run 15W-40 year round. I go to school in Pullman WA and it gets down zero and below and I never plug it in. Nowhere to at my apartment

Thanks guys

5-40 amsoil is what you need--never used 10-30 in any diesel

Try that at -30 to -40....Then you will understand why we are using either 5w-40 or 0w-40

That was the recommended oil for cold weather in the 7.3, ran it in several of our with no issues what so ever. 5w-40 syn is your best bet but it is much more expensive. As long as you are using a diesel oil you will be fine with the 10w-30.

Rotella (and several others) makes a diesel rated 10W30 that works great in the winter. It will make your PSD start easier and get rid of the romps right after it starts that you get with 15W40. I use to run 15W40 in the summer and 10W30 in the winter and it made a big difference in starting and initial idling. I now run a 5W40 synthetic blend year round, so I don't have to worry about my oil change intervals coinciding with the change of seasons. I know for a fact that Ford recommends running 10W30 below a certain temp., but I forget the exact temp. If all your glow plugs are working and you have good batteries it should start even with 15W40 though, unless it is way below zero.

Been putting 0w30 in diesels and gas jobs in the winter for many years, in mine and customers vehicles. Put your 10w30 outside in -25c and you'll see why.

I had a guy in my shop from Indiana a week or so ago with a Dodge. He was hauling trailers, got in here late and stopped for the night at the motel next door. That night it was in the mid -40's Celcius with the windchill. No block heater, 15W40 oil and his batteries were as close to shot as you could get. We pulled him in the shop, stuck a magnetic oil pan heater on, put chargers on both batteries and it still wouldn't crank over enough to start after an hour. Finally convinced him to put new batteries in after that. To top it off, this guy was going to tow another guy's Ford down to Minot because it blew up in town a couple days earlier and the Ford dealer here couldn't get to it for a week. I can't believe how ill prepared this guy was for cold weather and even more astonished someone would even buy a truck without a block heater if you know you're hauling into areas that are cold.

I never said at -30 to -40. I just said at around zero or a bit below a 15W-40 works. If it got that cold, I would lower the winter number. Leave the 40 alone though since there are good winter oils for the extreme cold

My local ford shop recommends 10-30 all year. Make sure its h-d diesel oil. Been running in my last 2 trucks with no problems.

i have 1 cummins 5.9, 2 6.7s, and cummins 4 cyl welding machine, all usin 0-30 for winter, will start rite down to -30c without pluging it in. 15-40 in summer

 

[snopropanther]

i used to run i think it was 30W40 in my jetta diesel. i was to cheap to actually fix the problem so i just added thicker oil in the summer and 0W40 in the winter. 2 oil changes a year no matter how many miles. 1 in the winter and 1 in the spring.

up to -25C i never had a problem starting without it plugged in. but after that it was a pain to start.

Ran 10/30 in my 01 7.3 for the last two winters and runs so much beter than the year I ran 15/40 all year. Even on cold starts with my 120 tune in!
