2019 Ford F250 6.7L OCI dilemma

[sw99]

So am I nuts...

My 2019 F250 has 3500 miles on the 15w40 but I just passed the 12 months so the OLM says 0% as designed. I am having a difficult time convincing myself that the oil has to be changed. I'm thinking at a minimum, change it in the spring since I might have 5k on the oil by then. The truck was purchased in December of 2018 with 8 miles on it. Current mileage is 17,4XX.

Run it longer or change it thoughts?

It is your vehicle.

 

[High Performance Lubricants]

Easily run it longer

 

[sw99]

Yes it is.

 

[Donald]

This a gas or PSD?

 

[Jimmy_Russells]

If still under warranty I would change it

6.7L PSD

Yes for another 13 months but I wouldn't lose sleep if I ran the oil out another 6 months.

If it's under warranty I would change the oil when the OLM says to. I have no idea but I could imagine that Ford can tell if you changed the oil when the OLM indicates.

I have a 2015 Ford-250 with a PSD and went to 5W40 synthetic and a bypass oil filter and I run 2X the OLM.

As others said, if under warranty change it. Otherwise, I'd run it more.

DO NOT extend changes on these powerstokes. DO NOT follow the oil life monitor. Change the oil 5,000 miles or one year whichever comes first. You will thank me later and your engine will too. I am a former ford tech just an FYI. Use 5w40 not 15w40.

I would like to hear some concrete reasons for this advice. Seems a little hyperbolic.

Time or mileage, whichever comes 1st, has its reason.

I prefer 5w40's because they are usually full synthetic. But, Ford has a great list of 15w40's that can be used too.

If you are under warranty, change it.

If you are not under warranty, do what you want.

Why are you using 15w-40 when it calls for 10w-30?

 

[Fahrvergnügen]

Why are you using 15w-40 when it calls for 10w-30?

It calls for 10w30 for normal use - for fuel economy, 5w40 for extreme use which if someone buys this truck just to ride around in and not work it, isn’t too smart.

So with the EGR and the heat these engines run and the soot they produce, is not smart to go past 5,000 miles. Also no consumer falls under normal service which is for 7500-10000 miles. all consumers fall under extreme usage. With that being said, it calls for 5,000 mile oil changes or 1 year whichever comes first. It even says not to follow the oil life monitor. We even change oil 5,000 miles on all of fords lineup. We have seen what happens to people who extended oil changes with these engines. Go talk to any ford tech and they will tell you the same thing I’m saying.

The 15w40 makes the engine sound like a typewriter. I can’t tell you how many trucks came in with consumers complaining about this noise. It’s from the 15w40.

I service a fleet of these in a 550 ambulance chassis. I have been doing so for several years. They easily see 400 hours between services on a bulk 15w40 with majority of idle time with full emissions equipment. Average engine life is 20K-25K hours. Not sure what type of service your vehicles are but ambulances are about as bad as it gets. Not sure what evidence to have to support your claims.

From my experience the only mechanical wear problem these engines suffer from are the rocker arms. Occasionally you will see tappet failure. Both of these are usually from excessive fuel diluted oil run too long. Just about every bottom end I’ve taken apart on these the bearings are still in excellent condition, even with with over 20K hours.

I will however agree with you that thick oils can cause the “typewriter tap” but usually it settles down a bit into the OCI. There is no harm being done by the noise.

That being said, my personal 6.7L I run 5w40 and use UOA samples every 5K miles or 200 hours to determine OCI. Currently at 8700 miles on current fill.

Run it longer, take out to 5k.
