Many times a leak on any spin on type filter is caused from the old sealing ring (rubber gasket) being stuck to the housing and left behind where the new filter ends up being double gasketed. This will result sooner or later in the seal blowing out and causing a massive leak. Anytime an old spin on type filter is removed, make sure the old gasket is removed and the sealing surface is wiped clean and the new seal lubricated with fuel or oil (for oil filters) before installing a new filter.

Also I cannot see what type of fuel filter is being used here but in diesels long ago I pre-filled the filters with fuel before installing. This prevents air from being introduced in the fuel system. Fuel serves as the lubricant for fuel system components.

Some diesel engines may have a manual pump and bleed to purge air from the filter housing.

Just FYI - You can also see it (oil life) on the FordPass app under Vehicle>Status (along with Fuel level, DEF level and Tire Pressures). Data is as of end of the last drive. Kind of handy.. saving you a trip out the vehicle and starting it up. Don't know if you get a warning about oil life as I haven't taken it down that low, but the app does show a "red zone" below 10% remaining.

You do get a warning near the end of the oil change interval.

howson Thanks, I will look into the link you posted. Maybe I am just paranoid but I follow the severe service recommendations when I am towing 6 months of travel per year and get an oil change at 5000 instead of waiting. I also buy from FordParts fuel filters and save a lot of money just paying for labor. The fuel filters get changed every 15k miles. Just got that done last week at the dealer in Naples. They charged $45 labor for it’s the cost of the filter at $72 it was some savings:

In Florida, check prices from Lakeland Ford very good deals and OEM free shipping.

Thanks for the tip. I have not been very happy with our closest dealer in Lake Wales and Lakeland is not much further.

Rob, I have never been to their service center. I
only order parts so can’t vouch for them. I only order through them as my dealer https://parts.ford.com/en.html

I shop all dealers and they are the cheapest. Always get air and cabin filters as well because I do this myself. But when I was in Michigan I tried to order from them as my dealer but it would not allow shipping to where I was for free.

Ugg - I am now at 4 pages of questions for my new truck PDI...if it ever gets here. My dealer is trying hard to see where it is at in shipping, but the Ford tracking system is wonky. It may be soon as Ford says delivery the 18th (passed) to the 24th. I am definitely going to have the service manager go over stuff. As for oil changes my dealer offers specials every month and you earn reward points too. They also have a program where after so many oil changes one is free and they can be any oil changes. Between my wife's and our second car, we saved the free ones for the truck in the past. For the Alaska trip I will be carrying a full set with me - just in case.

Now as to the % oil life it used to be x miles (5000 or 1 year on my 04 if I remember correctly) Is it still something like that or is it strictly per the computer now? I guess I need to look that up in the online manual.

I figured the Ford engineers had a reason for how they calculate oil life, so I use the % and (again) review prior to a trip so I won't have to have maintenance done while on the road.

**Guest** · 04-19-2022, 03:20 PM

How would a truck update miles to service if it spent most of the day idling? Not impossible but also not practical to use miles if an accurate model is capable of calculating when the oil should be changed based on percent.

Jim

**Cate&Rob** · 04-19-2022, 03:30 PM

There are a lot of parameters that go into the oil life calculation depending on how the vehicle is used. See my post #6. For example, someone who takes short trips in cold weather will have a very short oil life because they never boil the condensation out of the oil. On the other end, long low load trips (empty highway driving) will have the most miles between oil changes. Towing will be somewhere in the middle, depending on ambient temperatures and weight being towed. Apparently, my F350 diesel didn't think towing an 11,000 lb 5th wheel to Florida and back, amounted to much of an effort, since I still have 50% oil life remaining

Thanks Howard and Rob. I found some information in the online owners manual beginning on page 628. Its a table showing from basic use 10,000 mile change interval to Extrema at 2,500 miles. It mentions the % gauge. I plan to ask how how the truck can be so smart to tell. I guess long gone are the old days of sending samples off to Blackstone labs to determine if you changed the oil too soon. In my youth I could tell by smell and feel - back when oil was actually oil. Maybe that's why my hair fell out - sniffing oil

. I was looking up the new grading of oil the beast will use - you need a PHD in chemistry to figure out whats in it and understand the certification and specifications it must meet.

**Guest** · 04-19-2022, 04:09 PM

Yoda I was at GM in the dyno labs where extensive oil analysis was used along with software writers to develop their model where a basic outline is in post #3 in how it works. Other makers are most likely doing something similar.

I have told people for years that the smart folks have already done the math so its best just to trust that.
its easy to get way far into the weeds on the issue of oil life monitors

Some of the diesel engine manufacturers state that the filters should be installed and not pre filled (Cummins) in order to avoid possible contamination via the fuel container and the fact that they wanted every drop of fuel passing through the filter. The cost of injectors and pumps is significant. Most of the trucks had a priming process because of this. Of course it seemed like every series from every builder was just a little different. The easiest ones were the big spin on canisters that were on our old 2 stroke Detroits. We always pre filled them, they were pretty robust.

Rob

You need to break open fuel lines to change the fuel filter on the Ford? Seems like a pretty poor design if you do.
