This was my 4th GMC done engine oil change

 

All 4 oil changes have been filled to the same level ...

 

It is filled on my dip stick to between the 2 digits (the 2 and the 6)

 

Seems overfilled to me ....

I bet they are using the 8 quart spec for the Gen V 5.3 and 6.2 in the 1/2 ton trucks. I was always catching our guys when they launched those engines and the HD has the carry over engines. They would come up and ask me for a PF63 and 8 quarts 0w20, I'd hand them a PF48 and they'd look at me funny.

 

Heck, might even be possible that they threw 0w20 in it too. Hopefully the right filter as well!

 

Got your receipt somewhere? You can check and post the GM parts numbers that are on it that they billed out. Should be there whether its the free service or not.

 

Should be two lines, both are 8 digit part numbers.

From my Receipt:

 

6 19293002 Oil

1 19303975 (S) Filter

 

Looks billed right. Wonder if they are not letting it drain or are checking it wrong.

My last 3 6.0's were all serviced independently and were always between the hatch xxx marks and the numbers, and I just got used to it

 

My trucks always used about a 1/4 quart every 5000 miles their entire life, and I replace them at about 120,000 miles

 

My guess - Not much to be concerned about with my truck now having 18,000 miles and this will be my last dealer oil change ...

 

just odd it's over full by maybe a 1/4 - 1/2 a quart (?)

They're just adding that lil extra so you don't have to top off every 5,000 miles!

 

On a serious note, it's sad that the tech's won't double check their work. I get it, they see tons of trucks and do the same jobs over and over again. But you can't let your quality suffer just because it's a "routine" job. I was glad to get my free oil changes over with as well on my wife's Traverse....

I wouldn't be worried by it one bit.

 

It has to be really overfull to have issues, the issue that does come up when it is severally overfull is when the crank is churning in the oil as this creates foam and air doesn't lube.

It could be a motivation to overfill slightly like many dealerships have been doing to the oil using AFM engines in the 1/2 tons. that is only about a 1/2 quart more than the recommended fill. Not going to hurt anything.

      The Peckish Synapse

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.

      Diesel hit $6.00 here today at the truck stop.   Payed $2.79 for E85 today too.
