I took my car to dealer for the 6k oil change .
Right away a kid says GM recommends you add this stuff to your radiator to bring your antifreeze up to SNUFF.
We can do it for $29.99.
I asked how does antifreeze lose its snuff? Age and heating up and cooling.
I told him I'll check my antifreeze when I get home. I need to order a new snuff meter, I can't find mine.

Can antifreeze really lose its snuff?
Or is this the latest dealer con?

Does your tractor antifreeze lose its stuff?
 
Freeze protection lasts indefinitely.

Corrosion protection does not.

Realistic concern, especiallly with aluminum components.

Still, rather than adding snuff, I would simply drain and refill with 50/50 solution of new concentrated antifreeze of proper type and distilled water.
 
Geeeeeee Whiz George, everybody knows that YES anti freeze needs brought up to SNUFF lol

Sames true for old stale air in your tires, you need to hire the dealer to drain n refill with fresh air at least twice a year. NEVER leave it in over 5 years !!!!!!!!!!! Probably worth maybe a hundred bucks but hey its worth it to be safe right ???

SNUFF meters can be found on Amazon or Flea Bay I bet

Muffler Bearings need replaced often

However modern day oil lasts forever, save money dont change it, ask Billy Bob and Bubba. Those are the same dudes who wired their own homes while downing a couple cases of beer, what could possibly go wrong ??

The next time I hear my antifreeze needs brought up to snuff for $29.99 and GM recommends it I'm going to request they print me out a GM service bulletin and state what's in the snake stuff.

Remember the problems GM and Dodge faced in 2008?
I'm reading rumbles that US auto makers may be on the edge of Bankruptcy again,

When I learned in 2007 that GM wasn't going to make the classic body style, I bought a 2007, 8 ft bed, work truck 6 cylinder for $13,400 out the door cash price, all charges and taxes included.. That shows you how bad GM was hurting at the end of 2007 a little before the 2008 crash.

With the increase in Fed rates, GM financing is almost 6%.

That brings up car payments a lot.

I'm going to sit tight and wait for GM to fall again.

My money says we are going to be in for a hard landing again.
 
I thought snuff was the stuff littl old ladies did so they would look like they wre being all prim and proper by not smoking or chewing.
 
I had an episode where I consumed too much antifreeze and I lost my snuff. The next day my battery wad dead and I needed to get more antifreeze, but my snuff was still in my pocket.
 
Yes it can. Typically automobile manufacturers want it changed at 100,000 miles or so many years. It's the corrosion inhibitors that fail.. Truckers use an additive to bring it back up to snuff. NAPA carries it in a quart bottle which will cost you as much as the dealer wants.
 
i could write a lengthy page on the myths of antifreeze that i have found not to have any merit, your most accurate means of determining the level of protection you have is a good tester. years ago me and a coworker were making sure the trucks on the yard had enough antifreeze in them and the owner got to questioning the amount of antifreeze we were using, we had poured 4 gallons in a truck that only held 7 gallons which according to the testers we were using we were about -10, he went to explaining the protection levels of a 50/50 blend and the cost of the $5.00 a gallon antifreeze we had used. my way of thinking what was $20.00 compared to a frozen radiator or engine, funny thing it wasn't long after we got scolded about the amount of antifreeze we had used that a news report came out about antifreeze being used for boil over protection not working as it was basically colored water, which we had most likely got a hold of.
 
At 60K a coolant change is not out of the realm of consideration, or a coolant additive to replace the consumed anti-corrosion content of the antifreeze. Not replenishing the anti-corrosion content via additive or coolant replacement can certainly lead to expensive damage.

While I haven't noted it for cars, such an additive has been the norm for a long time for diesel engines (SCA). For the larger cooling systems in trucks / semis / heavy equipment, adding $20 SCA and getting another 50K miles out of the much more expensive gallons of antifreze is certainly a money saver.
 
Preaching to the choir, bud! Itold these experts many times in the past about some of their facts only to be told I didnt have a clue, when I use to make many of the additives in certain brands of antifreeze. I just stopped trying, on pretty much anything here anymore.
 
There was... and is... a service bulletin on the additives needed for the aluminum engines that needed to be replenish to stop them from leaking.... back in the '80s. Its real... However since I no longer drive a GM vehicle, I dont know if the newer vehicles still need it. I do know my diesels need an sca check and replenishment from time to time. And yes some called the additive package snuff. It was the Northstar series of engines that required the tablets or powder. So, I will go out on a limb here and say its probably a real thing... for you GM... but I would surely look at aftermarket vs the dealer.
