Seriously, once a week on Saturday. That said, I don't often ADD oil even if it's down a bit. Most vehicles I've owned, by the time they were down a quart (if they used any oil at all) it was time to change it anyway.
Just curious, but how do you get an accurate level reading in this manner?quote:

Funny stuff. Dipstick is immersed in oil, well lubed, removal and reinsertion speed low, makes for low wear on the dipstick. Could coat the upper parts with grease because they don't see much oil.quote:
how long will the dipstick last?
