Stupid oil change question?

[carlrx7]

Use a vacuum extractor from the dipstick. I use them to change oil on my boats outboard from the dock.

I tried this and couldn't get anything using my extraction pump. Anyone have any luck?

Also, FWIW, following FirePunk's advise...I learned after my first oil change that the oil gets dirty quick., but as long as it still feels clean between your fingers and doesn't stain, it's clean.

I took it by the dealer and of course they checked it immediately even after acknowledging it's supposed to sit for 30 minutes. It was only showing slightly overfilled and they suggested to leave it like it was. I just shook my head and left. Wasn't worth arguing over. I had the same problem with my last Cummins and a different dealer. I don't get why they can't get an oil change right. I guess I need to get one of those vacuum pumps.

One thing is you have to make sure the oil is warm.

I now run a Fumoto Valve which would solve your problem. I would start thinking of doing them yourself if you’re able.

I’m able, and I totally agree. I had a “we owe” for 2 free oil changes. Also, keeping my warranty in tact is a major concern. Not looking to give the dealer or FCA any reason to deny warranty. I read this on the fumoto site. I thought it was interesting that they were not more confident their product would not cause any warranty issues.

“Therefore, installing our valve probably won't void your warranty.

In the event that our valve causes any issues on your vehicle, the dealer may not cover the damage. Please contact your dealer for more details, because each warranty is different. “

I think the root problem is that our engines take considerable time for the oil to drain back down to the pan. Dealers and fast oil change places make money by volume sales, they cant allow the vehicle to sit on the rack allow time to drain properly, therefore a good bit of old oil is left in place. The tech looks up the published oil capacity of 3 gallons and sets his bulk oil dispenser pump for 3 gallons and then you have the overfill. Usually not to extent of the op's truck. I still do all of my oil changes, even after letting the truck drain for several hours, i don't believe i ever put the the full 3 gallons of oil back into my 13 before it hit the full mark on the dipstick. More like 11 quarts and a splash for that truck.

Also, for what its worth, i haven't off-roaded with my truck in recent history, but i have ran the fumoto valves on my 2 trucks since 2014 with no issues. Way easier to control the flow when draining the oil

I used to poopoo the idea of an extractor, but now that I have one I love it. Use it on my boat, the lawn mower and snow blower. While I still use the drain plug on my vehicles, its perfect for situations like the OP's where he'd like to drain a small amount out.

Yesterday, I did my fuel filters and drained out a quart of oil using the drain plug. It was very easy to unscrew the plug and tilt it a bit to drain a small amount. It wasn't very messy at all. I'm still struggling trying to figure out the readings I'm getting on the dipstick. I thought my driveway was fairly level where I park my truck, but I'm getting a huge difference checking it in the driveway vs the garage. I don't leave it parked in the garage because I cannot close the door. If I crank it up cold and pull it in the garage then let it sit for 30+ minutes the level is good. If I drive it for 8 miles or so and then pull in the garage and let it sit for 30 minutes it's still over full. I guess when I start it in the morning and then pull in the garage the oil is still cool and it needs more than 30 minutes to all drain back down?

I believe that the dipstick tube traps a bit of oil whenever the engine is run and takes even longer than the posted 1/2 hour to drain back down on our trucks. So checking the level too soon you can easily get a false reading thats shows too much oil. So i generally ignore "warm oil" readings.

I guess no one fills the oil filter with 1 quart of oil before they put it back on. I’ve been doing this for 20 some years on my Cummins. No dry starts.
