Spark plug damage

[FLYARMY]

@Slick Blackwings .....I'm a little offended. I hauled fuel for years and never cross dropped. If you are having issues with multiple cross drops, something is wrong. Poor tank markings, wrong markings, maybe bad drivers, new drivers, IDK. I'd be having a conversation with the drivers or whoever is suppling your fuel. There's no real excuse, but it does happen. My "home" store had 10-14 plus trucks a day dropping fuel and we NEVER had a cross drop in all the years I was there. If regular was crossed with super, or vise versa, it wouldn't effect a spark plug. Gas crossed with diesel, or vise versa, different conversation. The engine would most likely stuffer damage. Bottom line, it's not "bad gas". And most of us fuel haulers work VERY hard.....for you.

I have a question. Did you ever have to pay for gas while you worked for the company.....or did some gas ever "fall off the truck, into your tank"?
Just wondering. Or do they monitor every drop ?

My comment was not to offend anybody, simply a statement of today’s society, not paying attention. As far as our markings on our lids and tanks, they are completely correct neat and tidy. Unfortunately it’s just the way things are today.

Not quite sure what you’re asking there, I don’t work for the company I own it, and yes, every drop gets accounted for.

You really don’t want to know how incompetent fuel delivery drivers are, we own a fuel station can’t tell how many times fuel gets DUMPED IN WRONG TANK! I’m telling you it’s HORRIBLE! So in other words it’s possible to be pumping super and getting something else.

Really? The driver puts Diesel #2 in the Unleaded tank?

I simply made statements which I believe in , maybe you should just let it go.
Final answer from me on this.

The load is pretty closely watched with tank readings at the store and paperwork from the terminal. When it's full, you wouldn't want to even try to steal some, too much pressure. When it's empty, it's pretty much empty. Whatever is left isn't worth trying to get. I did have one store that would make me wait until all the cars left, taking a reading, dump the fuel, and take another reading. He didn't want to be "cheated".

Speaking of "stealing gas". Way back in the 70's during the gasoline crisis.....the cars were all gas guzzlers and my Dad drove a huge Cadillac Fleetwood. He owned a body shop near JFK airport and did tons of work for the many airlines. You would have to wait in long lines at the gas stations for at least 30 - 60 minutes just to get 5 gallons of allotted gas. They used to do ODD/EVEN license plates too. My Dad would siphon about a gallon of gas from each of the airline work trucks that were in the shop for work, in order to avoid waiting in lines. His take on the issue was, they would ALWAYS take at least 6 months to pay him for the work done and he was just taking the gasoline as an interest charge for having to wait. He would also switch plates on his car to take advantage of the ODD/EVEN plate rule.
** I worked as a pump jockey back in the early 80's in high school and had to take readings from the pumps at the end of the night and sometimes use that long wooden stick to measure the tanks in the ground. It was my first real job with responsibilities to open and close the station and count the cash and put it into the floor safe. Only bad side was coming home smelling like gasoline.

Hello, im new to the forum.

I purchased my 22 ct5vbw last November and have loved the car so far.

Last weekend it developed a solid misfire. Found it was cylinder 4 and pulled the plug to inspect it. I found it to be missing the electrode and ground strap and looked hot.

I took it to the cadillac dealership, they slapped a plug in it and said it was all good and guessed at bad gas. I dont accept this answer. I had to talk to the tech who said he borescoped the cylinder and found no damage but did no compression test. Said he did an injector balance test and all looked good so I should be fine.

I spent most of my life as a master technician and now run multiple stores. To me this answer is not acceptable, something had to happen to damage that plug.

After picking it up I feel a slight hiccup at lights which they are trying to say is normal and all blackwings do it. Can anyone confirm if they experience this?

I'll be doing a compression and leak down test on it either this week or next week to see.

My rearview camera also stopped working and displaying a blue screen, they said they updated the software and is working fine, it was still blue when I picked it up.

Anyone have issues with plug damage?

Now that these cars have been around a few years.

Im starting to notice as these cars are reaching 20ish thousand miles, people's plugs are getting eaten.

Mine as well. Ive found THREE plugs on my car with the exact same issue. Electrode nowhere to be found, and plug insanely fouled up. 22k miles....

My cars been nothing but trouble... i should have listened to the "bad motor stay away" posts

So would changing plugs at like 15k solve this or is there a larger problem?

No, something is wrong with detonation if your melting off the tips of your plugs?

Did you tell them it happened at the track? I track mine but worried about being denied warranty from it.

I didn’t tell them because it didn’t have a problem at the track, but they know I track my cars. I’ve never had a problem with GM honoring warranty after track use (unless you tune or do something like over rev on a downshift). I even unloaded my C7 off the trailer at the dealer with track tires and numbers still on it after the catalytic converter cracked.

When cars were first being released mid/late 2021 didn't GM engineers publicly state they're watching for cars specifically at tracks so they could "monitor the performance?"
