Hello,
I have a F250 2019 KR. I'm at almost 10k miles. I have a maintenance plan but I haven't had my first oil change just yet. Just recently I received an Oil Pressure Low warning when I started the truck. The error went away and the pressure return to normal. Should I be concerned?

Also, the owners manual is suggesting I change the oil every 10k miles? Is this safe for normal driving conditions? I would like to keep this truck for a very long time. What would be the best oil change intervals ?
Thanks

 

I would never run the break in oil for 10,000 miles, especially if I wanted to use the truck for a long time. Your oil life monitor is OK for subsequent changes.

If you had low oil pressure, either the oil level is too low or something is failing, both are bad.

 

My oil life monitor is just now going off.

 

I change my oil when the Oil Life Monitor prompts. ( other than my 1st oil change)

If you have concerns, Send a couple oil sample in for testing. Standard oil test are about $28. Get the result back and feel comfortable about the life cycle or change it to a mileage you are comfortable with


It's as simple as snagging a couple ounces of used oil during the oil change and putting them in the mail.

 

When I bought my new truck 6.7. I changed it after the first 3,000 miles. Than again at 6,000. So I'm changing it every 3,000 miles. I figure I spent huge bucks on truck. I can afford to change oil to take it the long haul. My plans are the same as you keeping truck a long time. The aluminum body should last one hell of a long time.

 

Playing with fire doing 10k oil changed on ford engines.

 

Just follow the Oil Minder unless you get close to a year without change. Also a single low oil event that disappears is not an issue, but for sure check the oil level once off and settled for a while

 

The oil minder will trigger at the one year mark automatically. Otherwise, it's based on usage. Mine triggered around 5K.

 

I went to 5k on my first oil change but I had my Filter Mags on the oil filter at 1k miles so I felt safe. YMMV. If it bothers anyone with the 17s +, change the oil filter and grab a quick sample at the drain bolt to get analyzed at 5k miles. You'll probably put in a few quarts or so of fresh oil. When the sample comes back and depending on the outcome, run it out to 10k and change it. If you want to go to 10k , great. If not, do it every 5k then or even 7.5k miles. This is where all our opinions are different. But one thing, okay two things need to be said:

Old habits die hard

and

This ain't your Dad's oil.

 

Anyone that wants to keep a 6.7 for a long time should be changing the oil every 5000 miles.... and I don't consider 150,000 miles a long time. Those of you that run a truck to 100,000-150,000 and trade it in have no idea what those long OCI did to the engine because it's someone else's problem now.

The EGR adds soot to the oil which is abrasive. The Regen cycles add fuel to the oil. The longer you go between oil changes the more wear the lower half of the engine is receiving.

I suppose if all you do is run on the highway towing a load, long OCI would be okay since soot and regens would be at a minimum. I don't think the majority of SD owners park the truck until it is needed for a long highway trip.

On the other hand if all the emissions systems were disabled it would be a whole different story.

 

Thanks. This makes much sense. I haven’t been towing. Just mainly long highway trips.

I got the oil changed finally, the service tech said the oil still looked new.
They did nothing for the oil pressure warning that I received. They said the oil change should fix it.

 

This pretty much sums it up . . .

 

At 10,000 miles your oil will be black as coal. Any "service tech" that says diesel oil looks like new after 10,000 miles and changing oil will repair oil pressure warnings doesn't have a clue.

 

So what do you think it is ?

 

When a customer reports a low oil pressure notification, the mechanic should check the actual pressure with a test gauge. You could have a defective sensor, a wiring issue or a serious engine problem. Until testing is done to determine the actual pressure, you should not have been told that an oil change fixed the problem.
