those first few seconds after you changed the oil

[artificialist]

I do get nervous even though I know I did the oil change properly.

My mother's 2005 Jeep Grand Cherokee would always make that noise for a few seconds after an oil change.

Some cars have it worse than others. The GM 3500 V6 made the absolute worst sound after an oil change.

I think it is related to hydraulic lifters or hydraulic lash adjusters, depending on engine design.

Are you guys waiting for hours until the last drop to drip out? A typical oil change is done under 15 minutes or less. I do not see how the engine is going to become "dry" in such a short time.

My new Subie has the filter mounted upside-down, so it has to be installed dry. I've only done a couple of changes, but I have not experienced any abnormal noises thus far. The oil low pressure light also goes out as soon as the engine start cranking.

My reason is the air in the filter getting pushed out down the crankshaft.

On the BMWs, the only time I even saw the oil light was when I had let the oil drain for several hours. I gave that up and change oil like I'm working for Jiffy Lube

My moms Elantra is probably the loudest car I have ever heard right after an oil change.

Filling the filter does nothing.

No, it doesn't. Filter media will usually absorb 100% of the first fill, and not even drip when turned upside down. Some synthetic media filters may not aborb all of the first fill, so you may have to experiment a bit.

The next time I change my filter I'll fill it through the oil filter outlet, to the outlet, and then quickly invert it to see whether any drains out. Even with a dry filter, the oil light extinguishes as soon as I start cranking after an oil change, so I'm not worried about it.

Heh heh, If you thin oil guys would use something a tad thicker than 0w5, maybe there wouldn't be as much start up noise.

I wouldn't worry about it. Just change your oil and filter at regular intervals. The engine should out last many other parts of the vehicle.
