Oil change interval

[09stroker]

What mileage do you change your oil at. I used to change at 5000 miles on my other diesel's. I'am thinking i may just wait till computer says its time to change. So far i have a little under 6900 miles on factory oil. Display says oil life OK still... Have 340 hrs on truck & around 240 hrs idling.

On a new motor I would have changed it by 3,000 miles. Going forward every 5,000 unless you use an oil analysis to help you maximize the effective life of your oil.

on mine as soon as i got it i switched to synthetic oil mobile one 5w40 hd diesel oil this stuff is sweet guys it 5W not 15W like normal diesel oil and you can run it year round and is very good in real cold winters like where i work in wyoming it like 30 below zero in winter and i ran this in my last truck and it starts up easy and warms quick you figure 7.99 a quart the new truck is 13 quarts thats 104 bucks roughly and then bout 12 bucks for the filter and you go to their oil website you can run the synthetic oil 15000 miles before changing however it does say tough abuse change every 10-12K miles so if you don't like worrying bout oil changes i would go synthetic i love it i work to much to change it every 5K lol

people might call it unwise but I am going to follow the directions of the owners manual and change it when the computer tells me it should be changed. I will however begin running synthetic when I do change the oil. I had great service with synthetic in my old '05 F250 that I traded in for the new truck and had no problems at all out of the engine.

I was going to swap mine out at 5k. One guy told me i couldn't use syn until about 10k because of the breakin? Do these trucks come from ford with synthetic or conventional?

the manual calls for the oil change at 7500 miles, but I am probably going to change mine soon as I have 5k on it now.

oh i was told they are getting rid of oil change services intervals and the truck will tell you when to change them. I guess the new computer on the truck is pretty smart and the farthest they have seen the truck go was 8,000 miles. To me i would still change it 3-5 thousand just like the rest of the vehicles in the world at least in my book

my customer said he went 8300 miles before it told ho change him to change the oil.

I changed out the factory oil at 5000, (usually do it at 1000 to clean out any engine building particles), at 10,000 I changed to synthetic, will run to 10,000 or until puter tells me to...

Well was on my way to fillup with fuel and my light came on saying to change oil soon. I had 6930 miles on clock. Had 302 running hrs and 200 hrs idling time. So iam at dealer now getting my free oil change. They tried to tell me that I had to pay for the urea top off I said it was suppose to be included in oil change. The service advisor came up and said it was part of oil change service.
