For my 2019 6.2L, the manual has a list of maintenance things to be performed at certain mileages and/or after certain length of times. For example, the first scheduled maintenance is at 7,500 miles OR 6 months, whichever comes first. The second scheduled maintenance is at 15,000 miles OR 12 months, whichever comes first. Had my 250 since November 2019 (15 months) and have only about 5,000 miles on it. I changed the oil and oil filter myself 6 months after purchase. I have not done anything else on the 7,500 mile/6 month maintenance list or the 15,000 mile/12 month list. I see no need after the first 6 months of mainly sitting in my garage to rotate the tires and perform other minor miscellaneous tasks, and then at 12 months (still fewer than 5K on the odometer) to inspect brakes and related parts, inspect exhaust and other driveline parts, lube, etc. I plan on using my Ford points to have scheduled maintenance performed the first three times, then after that I'll perform most myself. Am wondering if I need to be taking the truck into the dealer to be in compliance (warranty) with their maintenance schedule even though it doesn't make a lot of sense to me to do some many of the things when the truck isn't being driven much.

 

A truck that's not being driven is going to require minimal maintenance.

I go by the milage recommendation printed in owners manual and like you, put less than 5K a year on the truck......change oil once per year.

Heck, I may never see the big item stuff like tranny filter and fluid change, radiator flush, front and rear diffs.

 

Any way you slice it, eventually a vehicle is going to "go out of warranty".... The rubber components (hoses, weather sealing, tires, v belts, etc) all have a limited lifetime. I guess my question is, why do you own a truck that sits most of the time ?

I prefer to avoid maintenance in the winter or summer. Hence,,, I change my oil etc. the other seasons.

 

The only maintenance I preform that is time over mileage is my oil. I change my oil every 5,000 miles or 200 hours. I find that I do a lot of idling, especially since covid.

 

Me too, that crawling under a truck in the cold winter doesn’t interest me in the least.....garage or no garage.

 

I go by mileage. I bought a small car a couple months ago for DD use, and already have almost 2k miles on it that aren't on my truck. I will probably be able to do once-a-year maintenance on my truck now...

 

Answer - Why my truck (or any other vehicle that I own) sits most of the time is irrelevant.

 

those miles/dates/hours interval maint schedules are meant to confuse the layman and make it easy for the OEM to void the warranty claim.

Im in the same boat....2019 6.7 bought new mar 2019. so 20 months and 7000 miles. Ive changed the oil at least 4 times, the fuel filters once.

my plan is to do it twice a year if I dont make the miles.

im in what they call severe duty. metro area. we stop every other block and wait 2 minutes for a light to change. big time idle hours.

 

I am a low mileage driver and go by months. Still under warranty so, I will do what the manual says.

 

Got in the habit of changing on mileage/hours or calendar limits - whichever comes first. Before I downsized to one truck, the F350 sat for most of the winter but I still preheated and ran it to the next town at least once per month, and changed the oil twice a year because I never hit the mileage/hours before the calendar limit. Funny things happen to oil that has acquired any byproducts of combustion, build up of acids, etc., and then acquires moisture through freeze-thaw cycles. Moisture + acids = bad. That's why I would at least run it the 100 mile round trip. Shorter or just idling tends to add moisture rather than the other way around. Found that to be true when maintaining an aircraft engine. Pull the oil filler cap after a 20 minute in-place run and see the drops of condensation formed on the underside - at least with the Continental metal oil filler caps. Not as obvious on the plastic. Down to one oil burner truck now, first oil change coming up as I like to do the first way early to remove any excess products of initial break-in. YMMV, don't try this at home, yes i know i am retentive and often mis-informed!
