Question
How many people get oil changes after the thousand mile break in ? I have a 6.7 that should be here in the next two weeks hopefully. I know there is a thousand Mile break in before towing which is on another feed lol. I’m interested in the first oil change
I will be doing oil changes every five thousand miles. So do I do the oil change at a thousand miles or wait til I hit the five thousand schedule
 
I did mine and my 7.3 at 1,000 miles ( did myself ) used the Motorcraft oil and Filter. ( check Walmart they have the filters and the Motorcraft oil and it is reasonable.

after a few thousand I now run Amsoil in both 5-7k miles intervals. probably over kill
 
Plan on breaking in my '22 6.7 like I've broken in all past diesels. Around 1K miles of break in with highway and city driving then an oil change before heavy towing. I have always believed in a break in period whether it be a truck or piece of heavy equipment with an early oil change in order to flush out any contaminates from manufacturing.

Might be overkill but we have Cat engines with over 8K hours on them all original and 6.7's with over 150K on the meter.

Just my $.03 adjusted for inflation, YMMV.
 
I went 2500 on the factory oil then switched to 5w40 full synthetic with archoil 9100 friction modifier....now I change every 5000
 
I did my first change at just over 1k and then the second just under 5k and third at just over 9k along with a bypass filter. Used T6 each time.

With the bypass filter I may actually consider going closer to 10k but won’t likely get that many miles in a year so I’ll still change it yearly.
 
I have a new 2022 with only 3100 miles. Oil is black as can be and dash says I have 5 percent left… something seems wrong to me. Getting it changed now.

I agree with changing after first 1,000 miles as recommended earlier. When Jeep came out with the JL, some owners had issues that were traced back to casting sand residuals during production. If I ever get my Tremor, I’ll change first at 1k and then listen to the advice of more experienced folks for the ensuing intervals.

If you do a lot of short trips, especially in cold climates, then the oil will break down quicker. This is what my dash oil life gauge has been telling me as well. Almost every 3000 miles. I have done all my own, first one at 1000 miles and all with T6. 3000 mile oil changes seems excessive to me with full synthetic, but the truck doesn’t know what the oil is and only goes by programming based off the standard oil. I figured I better stick with what the truck says, for warranty purposes and so have changed it when it is around 5%. I have just over 11,000 miles on my 21 6.7 now. I think that miles between changes will increase in the summer, and of course will increase if you take longer trips. All programming based off trip length, outside air temp, engine temp, and I’m sure other factors.

Thanks. I’m having the dealer change the oil right now. I’ll likely do myself after this. The cost to have them do it is ridiculous.
How do you track your oils changes to prove you’ve done them for warranty purposes?
 
I am a FIRM believer in the use of oil analysis. I have used it for the last several vehicles and it yields very usual information. It identified fuel/oil dilution in my 6.4L which lead me to immediately do a full delete. Problem solved. It also gives useful info if someone is interested in extended use intervals(which I do not prescribe to as oil is cheap in comparison to our engines). It will also help to identify any coolant leaks in advance of catastrophic issues. I start with a voa(virgin oil analysis as a baseline) then do every oil change. Also builds a very desirable database for subsequent owners or warranty claims.

I have taken pictures with my phone of the new oil bottles, filter, and old oil drained in 5-gallon bucket each time, along with keeping the receipt from the oil and filter purchase. Phone date and time stamps all photos.

Oh, and of course I keep a maintenance notebook with all vehicles that I write down the date and mileage and details of any maintenance performed. Keep in glovebox with owners manual in ziplock bag.
 
To not have warranty issues, should you follow the owner's manual or the dash indicator?

You can log them in the FordPass app
 
What type of oil are you guys using? I stuck with motor craft filters in my last one and run Schaefer 15w-40

Yea, I try that every time I do it and it never saves it. I do put them all in the fuelly app though, along with my fuel ups.

Just my $.03 adjusted for inflation but I stick with Motorcraft filters and here's why.

On our '13 350 6.7 I tried to save a couple of bucks on fuel filters and went with aftermarket. I was pulling a Cat 279 on a 2 hour trip and the engine compartment filter collapsed and shut the truck down on the side of the hwy in the middle of nowhere. Fortunately there was a Ford dealer 30 miles one way that had filters so we were back on the road after a couple of hours.

Didn't learn my lesson the first time so I decided to go with an aftermarket air filter on our '18 350 and within 20 miles got the dreaded check engine light. Turned out the knock-off filter didn't seal the air intake to spec and threw a code. Replaced with Motorcraft the light went away.

Now I just order several filters at a time on Amazon. Running synthetic in the '18 and plan on swapping the '22 as it's approaching 1K miles. Usually I change synthetic around 5K miles and swap fuel/air in rotation with oil changes - fuel this 5k miles and air the next. Sometimes in the summer I'll change air every time but fuel every 10K.

It's cheap insurance in my opinion for a $90K truck.

I noticed when the dealer does the oil change the app service history entry just says “scheduled maintenance.”

Btw… a tip for dealer oil changes. Buy your own oil and filters and take it to them. Only pay them for the labor. It still hurts, but it hurts less. 👍
