The very same thing happened to my SUV but at least it didn’t explode - the morons didn’t replace the oil filler cap and blew oil all over the inside of the hood. Don’t ever go to Walmart for any auto servicing; once when I had the battery replaced they didn’t put the bracket back on. Went back next day and they couldn’t find it. Then too, went to have my tires rotated and the manager said they didn’t sell those tires - showed him the receipt that showed I bought them at his store.
Something similar happened to me. In addition, the mechanic attached several tubes incorrectly. I called Walmart, and was essentially told I was lying. That was 10 years ago.
I don’t shop at Walmart anymore.
I went to Wal-Mart for an oil change once, years ago. When they replaced the oil filter the broke off the oil pressure sensor. I left a couple big puddles of oil before I noticed, and had just enough lubrication left in my engine to get back to Wal-Mart to tell them to fix it. They first tried to tell me they had changed the oil the day before I noticed it, so it couldn’t have been their mistake. I didn’t exactly mention an attorney, but I did ask how they they thought a jury might respond to that story, and that’s when the manager decided to, “make it right.” Never used Wal-Mart automotive again after that.
About 46 years ago, a Piper tri-pacer (115 kt cruise) was able to keep up with a Cessna 310K (193 kt cruise).
I had flown my dad in the TP from the farm to Moline, Il to get the 310. He checked it over and asked the flight line kid to put a quart in the rt engine. We both took off: me first, with a few minute lead. When he caught up, he suddenly slowed up. I then noticed the rt engine was shut down. I had no problem keeping up with the 310. We set down at the local county aerodrome.
My best friend was riding rt seat in the 310 and saw oil streaks forming on the rt cowling. The line kid had left the filler cap off. Clean up time. Thankfully there was no fire. And the oil level showed it was only down a quart and a half. A night flight might have been the end of that engine, or worse... a fire.
