Anyone besides me run 50/50 antifreeze year round.

50/50 here as well but only 2gallons & the rest distilled water with water wetter, stock cooling system too

As Nick and others have said, water and RM-125 is the best. The post on not using a/f at a race track is also very true. I met a very hi-end car collector a few years ago an he said he would never have antifreeze in any of his cars. When I asked why he said if you ever get a leak in the engine compartment or a heater core leak into the interior with water and RM-125 the clean up and damage is minimal. I never thought about it that way.

I didn't think i would be the only one using the 50/50 ratio.

I have looked at the premixed antifreeze being sold and the 50/50 ratio seems to be the only one being sold.

Thanks to all for replies.

It is because the 50/50 ratio is the sweet spot for all climates.
You cant run too much (>70%) Ethylene Glycol for certain reasons. (See chart)
And you don't want to run too little - for freezing reasons
So 50/50 is the ideal spot (Again - see chart)
Which by the way - the pre-mix is for dummies - or those without another empty jug - i.e. a huge ripoff.

I look at it like oil - I change it regularly.
It just happens to be every spring / summer season.

And PowerMaster fluid, and rear end dope, etc.

Ethylene glycol is mostly there for anti-freeze protection.
Alot of ads are directed to the boil over protection, which a lot of hooey.
Even though Ethylene Glycol does have a higher boiling point, it is less efficient than water at heat transfer.
From Wiki: Additionally, the increase in boiling point over pure water inhibits nucleate boiling on heat transfer surfaces thus reducing heat transfer efficiency in some cases, such as gasoline engine cylinder walls
It is mainly antifreeze protection
And does come with some (many) additives to provide corrosion "protection".
RMI or other similar products provide the same protection.
So, if you would like to run less Ethylene Glycol - by using a cheap hydrometer, you can run the mix that suits your climate.
Be sure to follow instructions, since specific gravity changes with temperature, and you can get a false reading.
Then every spring or summer - dump, flush, and run some decent distilled water + RMI in the hot months to maximize cooling properties.

There would only be 5 months out of 12 that one could guarantee temperatures never drop below freezing. I suppose one could switch to water/RMI for those months.

For the other 7 month you could do like many of my customers and add RMI-25 to the antifreeze solution to supplement the minimal additive package used by the manufurer?

One thing RMI-25 will do that no other radiator additive will do is clean the system as you drive, without any caustic or acidic elements.

I look after a 30 car collection for a real estate developer friend and just trying to keep them all running at one time is a feat in it's self let alone trying to remember which cars have what in the radiators and what to mix with what. I can only help keep it simple

That must be a fun job though What do you use for rad fluid in them and what kind of maintenance program do you use?? Thanks for the input.

have a 55 gallon drum of anti freeze plus one of racing gas to.It's not as fun as you would think .The owner being a good friend from highschool and successful real estate developer with over 150 properties loves collectible muscle cars but has no mechanical abilities. so he usually calls the shop and ask one of us to go and service the car he wants to drive for the weekend may have dead battery flat tire bad gas ,leak of some sort having that many cars some may set for months at a time without being moved or driven.the real money for us when he ask us to restore one or buys one for us to redo which he pays handsomely the rest is just part of doing business.not being paid a wage to maintain his fleet makes it difficult to have any program other then trying to keep them running and make sure they have antifreeze in them in case of power loss to the building in winter some of these cars are quit valuable.that takes the fun out of it is the responsibility if something happens to it while we are in possession of it.It amazes me on how something can go wrong with a car just sitting I will always believe the worse thing on a car is just letting it sit.

I know of a few reasons NOT to use antifreeze all year.

One reason is antifreeze will run hotter than water since it does not transfer heat as well a plain water.
Since we are very aware of the importance of a good cooling system in our climate to protect our expensive engines, we highly recommend flushing A/F every spring, and use RMI-25 the rest of the year.

Exactly what I do, it's kind of a pain in the neck. I drain Antifreeze and flush every spring, fill with RMI-25 and distilled water. Antifreeze goes back in in November whe car goes to sleep for the winter. I keep the antifreeze ratio enough to protect to 0 degrees. If it's zero in my garage we got a bigger problem!

some of our older muscle cars that we take to shows in the summertime and wait in long lines or cruise at slow speeds we will run water and rmi so we don't have to deal with a overheat condition

I run good old 50/50 premix in both my turds. Life is too short to be draining coolant twice a year. I don't need rmi to prevent overheat even with a front mount . I change it every now and again.

Did I ever mention how much I hate winter

As I get older I find myself liking it less and less , each year I find more reasons to say inside lol!

Yeah and needless to say it could be perfect out all day and drop to near freezing temperatures by midnight. Spring and fall is good for that.
