Are all dealers overfilling engine oil?

[NOV87]

...but IMHO there is still absolutely no excuse for them not to be trained how to do it properly. It is probably the most basic and perhaps the most critical service as well.

Training takes time and cuts into shops profit. I have heard of some young "mechanics" pencil whipping oil filter replacement and only replacing oil, otherwise they'd fall behind allotted time. Scumbag shop owners, most of them are, unfortunately...

Heres a video of a Ford dealership doing an oil change. Looks like a NASCAR pit crew Check out how he bangs the door into the lift at 0:25. He checks the oil level at 9:00. No way he can get an accurate reading on the dipstick 5 seconds after the engine shuts off.

Guess I should check my oil. I had it changed last week. I've already made the decision to start changing the oil myself. The last two times I took it to the dealership they added too much air to my front tires. Supposedly need 60 in the front and 80 in the rear. They switch those every time! When I get home I check the pressure and sure enough they have 80 in the front and 60 in the rear. I can understand the mistake once, but twice? That borders on incompetence. I'll be checking my oil level today.

Watch it when U get oil ref yer 6.4, because they will put in same barrel oil that they use for the 5.7, which is not the recommended for the 6.4, just saying...

There are 2 ways to do a oil filter change

The first way is to fill the oil filter & then screw it onto the engine

The other way is to screw the new empty oil filter onto the engine

No matter which way it is done is OK, IF only 1 person is doing the oil change..

Often 2 people are doing the oil change & that is when the most mistakes are made

I never have filled a new oil filter with oil first, but the hemi is the only one that even seems possible, due to the filter being placed vertically (aside from the fact that it was placed in a ****** location).

Should I fill it first?

I about half fill so I can oil threads and gasket

I think the Techs trust the automatic shut off too much, if they ever even check the setting between vehicle oil changes

This has been my experience also. In addition to once claiming they changed it when they didn't. Ask me how I proved them wrong. Then they were nasty to me. Done with dealerships.

Yes - pre-wetting the element allows fastest oil flow-thru for minimum oil starvation time on the poorly-lubricated valve lifter rollers. I fill my filter, then drain the oil. After I put the drain plug back in and take off the old filter, I know the new filter element is fully saturated with new oil.

Then I pour the new oil out of the filter back into the bottle, and install the filter. Simple.

Since it's so easy to fill a filter I always fill first before install.. on my 5.7 And lay rags on the steering part to absorb messy oil.And spray carb or ether spray to remove any old oil from it that may have gotten thru anyway.Imo an old 2.8 chevy v6 was a worse engine to change the oil on in comparison.And a dealership will never change my oil.

I personally have never filled an oil filter 1st on any car/truck. But since the Hemi is vertical, not an issue. However, on my flat bore V6 Honda 1833 CC MC engine, it is highly recommended to fill filter till saturation and then at least 1/2 way up. Due to the flat 6 cylinder, U end up with oil starvation on a newly changed oil/filter job (takes 10 seconds when filter dry, at least, till U build oil pressure), worst thing U can do to a bike motor. I just did my Honda the other day, and the filter is not vertical, it is horizontal. Just lost a few drops. Just do not fill the filter to the very top.

With my new to me ‘19 bighorn, I had a few issues, even with it being a certified pre-owned. Currently, I’m getting a “putt putt” sound, if you will, at start up and while driving. Almost sounds like exhaust issue (had one already just before the muffler). This sounds like it’s at the bottom of the engine. I checked the oil since I’m getting an oil smell after driving it a little while. After the truck sat for a while, I checked the dipstick. Level is high. 1/4”-1/2” above the top dot. Dealer did oil change last. I read a lot through this thread about overfilling won’t usually hurt the motor, but would it cause cavitation? Could that be the sound? (Can’t figure out how to upload the video I took for the sound)
