Oil filter change interval

[BilTheGalacticHero]

I have a 2016 Ford F150 5.0 V8 that I'm not driving enough to change the oil by mileage. The oil life monitor is hitting zero after one year. I'm running synthetic oil and a Mobil 1 extended life filter. I'm going to change the oil due to moisture contamination concerns but I'm wondering if there's any reason to change the filter or if it can go to the next change (in a year likely)?

Thoughts?

Thanks!

Use a cheaper filter and change it every year

How many miles actually?

I would consider running the filter another year if it’s already on and significantly less than 5K

continue doing what you're doing

I would do what you are doing -- do two OCIs with a top/upper quality filter like the one you are using.
(I do this for my mother's vehicle, which gets about 5-6k miles in two years.)

Or you could use a cheaper filter and change oil and filter every year.

IMO

Where is the moisture coming from?

 

[Hirev]

I got 2 vehicles that don't get many miles a year on so I just change the oil once a year and the filter every two years. Been working out well.

I believe even the "high end" filters recommend to change every year. I would just run a filter you can get for cheap like a supertech or something similar. I got some Purolator Techs and Ones for less than $3 on Amazon before.

 

[JunkdrawerDog]

I do 3k miles per year. I change the filter every other oci per owner's manual.

I would change the oil and filter together so that you have 100% clean oil in the end and not a filter full of dirty oil mixed in. Go with annual changes if you are concerned about moisture.

Combustion blow-by past the rings and into the nottom end. If it's short tripped, and the oil doesn't get hot enough long enough, then the oil can become moisture contaminated. Ever open up a PCV catch-can after a bunch of short trips, especially in cold weather? Or look under the oil fill cap and see the light brown bould-up for condensation build-up?

With a Fumoto valve - leaving a filter on 2x5k is a dream for the 2nd change …

If you're doing once a year oil changes, the cost of a filter isn't even worth thinking about. Change it. If you spent $12 bucks on the oil filter, that translates to around 3 cents a day.

The government announced they quit making pennies, because it costs more to make them than they're worth.

I adding to this good advice in saying to change the oil in the spring if you are doing a yearly oil change. I believe that the winter is the hardest on the oil as far as moisture and fuel dilution.

Most of my engines get very few yearly miles. I don't go by calendar recommendations or I'd be draining good Mobil 1 after 600 miles. They go for years between oil changes. I just go by the recommended normal use mileage intervals. No motor problems either.

The only exceptions are the Moto Guzzi and the Mitsubishi Mirage. Tiny sumps on those so I change the oil at the severe duty intervals (half the normal use intervals) and do filter changes at the normal use intervals. Have cut apart many oil filters and never found a speck of dirt or debris.

Yes. When I worked at a small town dealer 30+ years ago we would see this every so often, especially in winter. Small town - people would start there car, drive a mile, turn it off and walk into work. Rinse / repeat. Hard on oil.

With oil filters being a crapshoot when it comes to build quality, why worry about $10-12 a year for a new oil filter? That’s if you wanted to stay with the Mobil 1 filter for some reason.

I would dump the oil & filter after a year due to dilution / moisture / etc. Just use a cheaper filter so you get a complete / clean oil change. Makes no sense IMO to leave a year old filter on. Ecogard filter would do the job.

 

[Urshurak776]

Well, according to lickity split 10 speed lake dude, the longer you keep the filter on, the more efficient it gets.

Take it for a drive on the highway and any moisture in the crankcase should get boiled off before the engine is even up to full temperature.

As for the filter, I'd leave it on for two years. The main risk of using a filter for multiple years is that it the canister could rust and start leaking, but I've only ever seen that happen with FRAMs.
