This is probably a dumb question, but what the heck...I changed the oil in my 69 Chevelle today and tonight it dawned on me that I had forgotten to put oil on the gasket of the new filter before installing it. I think this happened because I am 58 and my memory has gotten very bad. I try to take Ginkgo Biloba to help but I keep forgetting.
Anyway, I was wondering if I should take the filter off immediately to keep it from sticking and being very tough to get off in three months. I only put it on hand tight but I don't want a repeat of the few filters I have had to destroy to get off aver the years, (however, these were tightened with a wrench). Thanks for your opinion.

As cheap as the AC filters are at "Wal-Mart", I would take it off, chuck it and put a new one on with whatever oil you need to top off. I have the same problem with the memory deal, 54 soon to be 55.

I almost never oil the filter gasket on a Chevy. There's plenty of oil on the casting that the gasket contacts, and you'll remember that the oil spills over the edge of the filter when you unscrewed it.

You've got no problem there.

Yeah, as long as you don't tighten it down with a filter wrench.

As a semi-mechanic, 1 out of 10 trucks that came in I could pull off using a regular filter wrench, the others were always completely mangled

Just my opinion but I would change the filter. It would worry me the whole time until the next oil change that it would stick. You can always get them off but they always stick when you don't have time for them to stick if you know what I mean. Like when you're getting ready to take the car somewhere the next morning you don't want a stuck filter. Just change it.

If it bothers you that bad you could just unscrew the filter a bit(remember how the oil started running all over the place when you changed it?) I really dont see a need to change filters or even take it all the way off. But like Schurkey said, oil was all over the surface of the block, unless you wiped down the sealing surface like I do
(it probably aint a big deal but I get a little fanatical at times)

Sticking is why you oil the gasket? That never occurred to me! I always oil mine but some still stick ocassionally, especially with my diesel engines. I always thought the purpose of oiling the gasket was because the gasket was made of the type of rubber that expanded when exposed to hot oil. Installing the filter hand tight was OK because the sealing would increase when the gasket expanded. Was I wrong?

By the way, kiss off that Ginkgo Biloba crap. Memory is a function of nerve synapses. Take six potassium gluconate tablets a day. One tablet is only 3% of the RDA. Potassium is the electrolyte you need to get those synapses working!

You guys are the Youth of this Country to me. I would not worry at all on the filter...especially if not wrench tightened. I fill the filter with oil before mounting, but there is plenty of oil left on the mounting area if you fail to oil the filter gasket. I notice many posted opinions on filter quality. There is a big difference in major brands ...to satisfy yourself, cut open two and look at how much difference in paper area (pleats) and the difference in how the paper is secured in the filter. Two major brands that are used on our engines are very different inside; one has 30% more filter area and supports the element with a steel cap ... the other has sloppy filter spacing and uses a cardboard plate on the end. Forgive me for being old and grumpy, but I bought a nice El Camino recently ...leaking at oil plug ...had to put short cheater pipe on wrench to get plug out of pan. Why does ever oil change place have to overtighten??

If you change your oil every three months I don't think it will stick badly in that short time period.

When I was in school I worked at a local garage. Day 1 the boss said,
"I'm gonna teach you how to change oil. I know you've done it 1000 times on your own but this is how we do it here."

Part of the procedure is to wipe the gasket mounting surface on the engine when you take the filter off. I no longer remember the primary reason he gave for this but he added,
"...and you don't double gasket the new filter."

Sometimes the gasket stays on the engine when you spin off the filter.

Since that day I've always wiped down where the gasket seals on the block.

Another guy that worked there did the double gasket thing more than once. You should see the trail of oil you leave when you do this.

Talk about trails of oil... I forgot to remove the thin canister style gasket one oil change. The concrete slab had 3 qt. of oil in a matter of seconds. Time to get the cat litter! Since then I've gotten pretty good at changing the canister style oil filters.

I believe that the reason for putting oil on the gasket is just so that tightening the filter is easier. It helps make sure you can get the filter tight enough by hand. It probably also prevents the gasket from tearing or slipping.

You should wipe off the oil filter flange. Not to remove the oil, but to remove the dirt. Dirt can accumulate around the oil filter during normal use. When you change the filter, this dirt can cause the filter gasket to not seal properly.
