Not wise it starts to slush at minus 34. If you were realy that on the
ball with this you would not be risking 50/50 at 40 below. The only
thing that saved you is that when anti freeze freezes it goes through
a slush stage first for a while and rated freeze temp and has to get a
lot colder to get solid. I promise you that if you take a bucket of
50/50 and set it outside at 40 below, you will have a big slushy not
liquid. Detriot has got to love you guys.
Never had any trouble at less than 50/50. Never had a slushy at 50/50
either. I had a slushy once with a vehicle with maybe a 20/80 mix at -20
after it sat overnight. It was a company truck that someone else was in
charge of. I found out that the mix was light! It never froze hard enough to
break anything, but I had to take my time starting the engine 4-5 times
until the coolant would flow through the radiator.
Trust me 50/50 will never be a problem or we would have had cracked farm
equipment engine blocks every winter!
Sno, don't you find it strange that you are all alone on this, and many
other points?? Can you find ONE reputable source to back you claims?? Please
post the links!
"If more is good, too much is just right."
I suspect that your practice of running high anti-freeze
concentrations relates directly to you using propane/butane in
your vehicles air conditioning; you can't get either to work
correctly because of your lacking skill set so you hack a repair
using non-standardized (and in one case, illegal and dangerous)
In the trade, you're known as a "Bubba."
yup we have noticed. that's the problem he wont answer the questions.
here ill ask again, and yes SnoMan I'm going to ask until you answer.
tell me where I can find a "Knock Sensor" on a 8.0L v10 (488)
you claim or imply its there.
The manufacturers use a 50-50 mizture based upon testing and chemical
analysis. It has been proven to be the IDEAL ratio based upon millions of
vehicles sold... nothing more.
By your analysis then, the anifreeze manufacturers should want to increase
sales by recommending a higher ratio, right? Visit any antifreeze
manufacturers website and you will see that the recommended ratio is 50-50.
Are they not interested in profit.... please explain that dichotomy?
In fact many offer a pre-mixed product in a 50-50 ratio? If they like every
other business was only interested in profit would they not offer a 70-30
products as you suggest? Please explain that if you can.
THere was a time that detriot said 40/60 was best too. The
I don't understand the physics behind it? That's a hoot! I'm a degreed
engineer with a major in EE and a minor in physics. I have been employed in
the auto industry for over 35 years, the last 18 with DaimlerChrysler. I am
ASE certified, I am a member of the Society of Automotive Engineers, I am
on the advisory board of the local voactional college and a member of the
advisory board for DaimlerChrysler training. Those are my credentials, what
Sorry to say this Snoman, but the others are right.... you are making
yourself look like a fool... it's very sad... very sad, indeed.
Detriot loves lambs to can be easily lead to
"'tis better to remain silent and be thought a fool than to open your mouth
and remove all doubt..."
Yes, ol' "tender tush" has tested them in prepartaion for winter... can't be
too careful I always say..... at least when y'all are freezing your Yankee
asses off mine will be nice and toasty... thank you very much!
Wouldn't it be a lot cheaper to make 2 taco bell stops and just drive an ATV
backwards instead of that big truck with a plow?
Mike, not quite correct, check this URL...
Look down the left side for "Technical stuff" then "Antifreeze and you"
You can see that 60% is the max for minus temps. Admittedly 70% is not
far from it, but since we are tossing around facts, I just wanted to
get your story absolutely straight for you.
Thanks for the reply! It would seem that the folks at Prestone have a bit
of disagreement with your 60% figure.
also, the folks at Peak also indicate that 70% is the max ratio for freeze
Hmmmmm.... curious.... I read your link and it appears this came from a
study by the University of Alaska. Those folks should know above freeze-ups
IMHO so there is a bit of controversy isn't there?
Suffice it to say that the max ratio is somewhere between 60-70%
coolant/water and everyone should be happy except perhaps for Snoman who I
suspect still maintains that pure antifreeze is OK.
Thanks for keeping me honest!
