Oil Filter Change Frequency

[Marcus van Bers]

It has always been my practice to change the oil filter every time I do an oil change. However, in reading through other threads on oil changes, oil issues, etc I get the impression that not everyone changes their oil filter when they do an oil change. I am curious if this is a common practice with others or if there are just a few outliers that do this?

And if you don't change the filter every time you do an oil change, how often do you change the filter and do you still suck the oil out of the canister that remains when you drain the oil.

[David Jones]

I have always changed the filter every other oil change and I always remove the filter canister to clean it out. It is not difficult to remove and is just as quick as using a turkey baster which can be messy.

[Ned Hamlin]

As with David, I change the filter every other annual oil change. I remove the filter and I'm one of those who sucks the oil out with a turkey baster. Fortunately, I only put about 1000 miles on my driver per year and the Swepco never gets very dirty..

Oil and filters are CHEAP, motors are not, I change the filter every time. ............Jim.

How about the sump plate?

How often do we pull that off?

[Dave Erickson]

I pull the sump plate every oil change. Then I look at the iron dust attracted by the magnets and thoroughly clean them. I added a pair of extremely strong magnets to the inside of the sump plate. Strong enough that they hold up my ⅜ ratchet when I am loosening the nuts.

Smart!

When my 1962 356B S was a daily driver, I used to change the 10W40 Quaker State about every 1200 miles and the filter every 10,000 miles. These days I change the 15W50 Mobil 1 every 2,000 miles and the filter every 10,000 miles. When I change the filter, I clean out the canister. None of my filter canisters leak. (I still have the 1962 1600S bottom end, the pistons, cylinders, and heads, have been changed. Mileage is pushing 160,000. Engine bearings are still std.)
Note that the dirtier the filter gets, the finer it filters. The dirtier the filter gets, the greater the pressure drop across the filter. Draw your own conclusions.
