I usually replace gasket every other oil change.
Just went to part store, the sales person tell me don't need replace if no leaking. Is it correct? Thanks.
Unless I buy an oil filter that comes with a crush washer from the dealer, I never replace it. The important thing is not to crank down the drain plug so hard that you mushroom out the washer.
I would always replace it at every change, their too cheap to take a chance.
"the sales person tell me don't need replace if no leaking" Sure but that's before you removed and re-used it!
We are talking about a part that costs less than 50 cents to purchase. Some of us spend 10 plus bucks on an oil filter but will skimp out on a part that's very inexpensive to replace. I replace it every time on the Accord and replace as needed on her Equinox.
