How to know if oil has been changed at dealership

[Bigkevschopshop]

Pull the dipstick, rub some of the oil between your fingers. If it feels gritty, they damn sure didn't change it. Honestly 20 miles that oil should still be translucent for the most part. I would actually drive back to the service department, pull the dipstick right there and ask them if that looks like 20 mile oil to them? Then ask why the oil filter has dirty oil on the bottom of it if it was just changed. Sometimes the service manager may have to get involved, but normally they will make it right.

Remember alot of lube techs came from places like NTB, and NTB stands for "Not the brightest"

Just like the guys that use tools to install dry oil filters. FML.

Yeah, so simple to pre fill a filter to extend motor life drastically, but dealers are about that $ and speed, and if your motor wipes a bearing, they get a motor job out of it.

I should definitely take before and after pics of my filter and drain plug next time .

I just crawled under and took some not so great photos .

It looks like the filter has a decent amount of oil on it ; it seemed relatively wet still .

It's a known issue that the LM2 oil filter will vibrate loose and leak oil if not installed tight enough. Always go one full turn after the gasket touches the sealing surface with a dab of fresh oil on the gasket.

There's a video on Youtube of an LM2 owner that had a loose oil filter and at least a forum member or two here that also had spotting on the driveway which revealed the filter was coming loose.

What's the deal with these Durajunk engines anyway? Glad the diesel in my Jeep has a canister style filter.

The motor in your jeep was so bad they got rid of it all together lol. Good luck with it.

Thanks so much . I was using this exact tool set , but looks like the dealership torqued it to insane levels . I used all my effort , but at the first sign of rounding the bolt , I backed off , lest I create a disaster

If you used the correct size 6 point socket, it will not round the head of the bolt.

The sad truth of this is , I usually change the oil myself but let the dealership do it months ago so I could develop a rapport with the service department .

I tried changing it myself once again a couple of days ago but found that they had torqued the drain plug to a superhuman spec that I couldn’t untorque, so I sent it into the dealership once again lol

I replaced my plug upon my first oil change with a Fumoto type valve. It is tucked away and cannot be damaged by road debris. Eliminates fighting with issues like this and has worked flawlessly through at least 4 oil changes. Pipes the oil right into my container that I take to recycling.

My 3rd gen seems to have only 1 issue, fuel pump. I haven't heard or seen much in the line of issues for this gen.

Then again, engines are rebuild-able, software is convertible. When warranty is done, I can decide what to do with it. LOL

Based on your pictures I'd march right back in with the information stated above. Oil filter is leaking, oil is black as coal after 20 miles, technician obviously isn't conscientious about their work. Nothing other than a sticker says oil was changed. Make them do it again, with care and precision this time.

Sent in the lm2 Yukon for an oil change today . When I got home i found that it appears that they forgot to reset the oil life monitor . Is there any feasible way to check if the oil was actually changed ? The oil is already pitch black as expected for a diesel

It is very common for them to forget to reset the oil life monitor. I change my oil every 3000 miles so it's difficult to tell visually.

Send a sample to be analyzed. Blackstone. Then you will know and can share with dealer if necessary.

First question to ask is if they actually put oil in after draining. Check the dipstick.

 

[OR VietVet]

There was a time where I lived where I could not change my own oil. I always picked up and checked my oil dipstick before leaving the parking lot.

^^^ THIS. Trust but verify. Or don't trust, but still verify.

 

[petethepug]

Ask them if they really want to correct the issue or do this like gentlemen.

Tell them ABC Indi shop put a torque wrench on the filter. It’s 70+ lb and still not coming off. It’s leaking. The oil is gritty. ABC shop took a sample from the dipstick, it’s gritty & black after 20 miles. The oil life monitor is not reset.

Should I pay you guys to change the oil again? I can send the other shops sample off for analysis in the mean time. I can come come back 45 minutes after you change the oil today and make a 20 mile drive to show you what it should look like?

Let’s get that stuck filter off the truck, change the oil and write in my new RO what the filter was torqued to OK?

You might find the oil was never changed because the dealership couldn’t get the filter off from your last oil change there. You might have a pan they fubar that they’re hoping to conceal and blame on you.

Have a verifiable shop pull an oil sample and check the torque on the oil filter for reals.

 

[BattleTank]

I didn't know oil filters are torqued? Most have diagrams on side indicating, once filter touches, its 3/4 to 1 full turn. No more. Unless specified differently in OEM service manual. Not corporate ****** oil change manual.

Drain plugs are torqued, not with ugga duggas. Anyone using a gun on a drain plug IMO should be fired.

 

[petethepug]

This is definitely turning into a 70 lb of ugguh duggah on a twist on oil filter.

 

[Stbentoak]

I've never done anything but hand tightened plus 1/2 a turn on oil filters my entire life. Never had a leak never had a problem. Same with drain plugs. Finger snug, then maybe one more turn. How hard is it? I don't break out a torque wrench unless I'm working on lug nuts.

 

[GMCnewbee]

Maybe the Dealer mechanic couldn't get the drainplug out either! I have never heard of black oil after an oil change.

 

[steiny93]

from the pics you can see used oil dripping down the filter and on the cross member; those aren't from a leaking filter as the OP would have oil all over his floor and the leak would be covered in road grime

the oil was changed

based on the replies, i'm surprised someone hasn't suggested the OP get a lawyer; guessing that's next
