Don’t know about your location, but my Walmart guys have been the same bunch for last 6 years
They let me in the pit check things out
If the Dealer tells you to fuel at a certain station only on even numbered days with a full moon. Go for it. Don’t knock what others do
PS
A lot of boo boo’s have been found after truck leaves the dealership service also
Filter never changed etc etc

Well, the OP does not have any of those engines nor powertrains, and not even a Cummins engine (not Cummings).

Good luck with your Walmart, semi-DIY maintenance. I suspect very few people will want to try that route. Not many places would let a customer work on their vehicle, and I wouldn't at my shop. I will let them in for a "show-and-tell" if they need to see proof of a defect or something, but they generally have 100% confidence in me.

It doesn’t require a lot of intelligence to twist an oil filter off and a new one on. Nor does it require much thought to remove a drain plug and reinstall it after draining the used oil. Taking the cap off an pouring in fresh oil hardly requires an master mechanic.

I fit each of those categories and have been changing oil for half a century. Paying a certified mechanic for such a simple job, in my mind, is like paying a brain surgeon for a haircut.

If you worked in a shop like I do and fixed so many DIY jobs gone wrong, your tune might be different. Just knowing what is the proper spec of oil is not that simple these days. Just witness how this thread has gone wrong. I bet not 5% of folks know what dexosD spec oil is.

"Just throw some Rotella in it" say some folks, "it'll be fine" they say. It's not their $$$ on the line.

Knowing what oil and filter is good, as well as knowing what OTHER stuff needs addressing is key. THAT'S where most DIYers and lube shops go wrong.

To each their own. It doesn't affect me nor my business. I only try and give the best advice I can.

Its as easy as boiling water. No rocket science needed. Even someone that spent 35 yrs. in kg can get it right.

Here is me .02c. My next-door neighbor worked at a local Subaru dealer for 20+ years. Over the years that have had 20~30 entirety level oil change techs ,of those 20+ years the dealer has had to tow back 2~4 cars a year for oil filter left loose or no oil in the pan when the tech parked the car outside for pick up, even a few that made it 2 day on the road and the drain plug the fell out because it was left loose.

Rocket science , NO! Competent tech needed 100% YES

I will take my car/trucks to only someone I know and trust, not some kid that came out of Burger king yesterday and mastered the oil frier.
