Thermal and Fluids Engineer here. I have to give props to Engine Ice's Marketing department. They are very good at misleading people into believing they have a better performing coolant, and are making millions off pure marketing and consumer ignorance. The cooling performance increase of engine ice vs regular coolant is just due to it being ~60% water, 40% Propylene glycol (PG), where normal coolants are 50/50 Ethylene Glycol (EG)/water. Water is a better coolant than both PG and EG, and pretty much any other liquid. So with these coolants, the higher the water concentration, the better the coolant mixture. Engine Ice is just a watered down coolant. A 40/60 mix of EG/water would actually be slightly better than 40/60 PG/water (Engine Ice). The boiling point of these coolant mixtures is only a few degrees above just water. That 256F they advertise is not at atmospheric pressure, where water boils at 212F, but instead this 256F is under pressure of a radiator cap, likely around 1 barG. Straight water at that pressure would have a boiling point of 250F (@ 30 psia), so really not much difference there, Tricked you! Equal mixtures of EG would have a slightly lower freezing point than PG mixtures, making them slightly better; or you could say, for the same freezing point, you could have a slightly greater water concentration using EG, and a better coolant. The biggest difference between EG and PG is the viscosity, where PG is higher viscosity (thicker), taking more energy to pump through the system, and providing a lower heat transfer coefficient than equal EG mixes. EG is also a non-polar molecule, which makes it slippery and a good lubricant, where PG is polar and not slippery. This is one reason PG mixes like engine ice became popular as they are polar molecules like water. When EG (non-polar) spills on the track, it is a slippery hazard, where PG will not be so slippery. For spill safety, some tracks only allowed PG, (or pure water) so people began to associate PG coolants like Engine Ice with: race tracks, racing, and high performance, when really it was only about slippery spills on the track, not anything to do with performance of the coolant, which is actually lower for the same mixture ratios. As far as Deionized (DI) water, that makes zero difference vs distilled. I have DI water systems for power supply coolants, and you have to constantly de-ionize the water by flowing it through DI resin beds, else it becomes regular ionized water within minutes. So that De-ionized water becomes ionized in no time, which is actually good because DI is also very corrosive as it steals ions from the piping walls/radiator etc. So the marketing of DI water in Engine Ice being a better water than other waters is just BS, they tricked you again! The real benefits of PG coolants like Engine Ice are 1.) It is non-toxic. 2.) Spills on the track with PG are less slippery than EG. But in every other way, EG and PG and quite indistinguishable, with EG having a slight advantage in freezing point, and a clear advantage (besides price) in viscosity, meaning lower pumping power, and higher heat transfer coefficient. I use full strength automotive EG, and mix it with distilled water myself to achieve the desired freeze protection I need, where 40/60 EG/water gets down to -10F, and 40/60 PG/water (Engine Ice) would only be around -7F. At operating temp, the EG mixture would have about 15% lower viscosity than the PG mix. EG is the way to go unless you care about toxicity or spill slipperiness, don't get tricked by the Engine Ice marketing.

I know this video is a bit older, but just wanted to chime in. Recently I changed over to engine ice on my GSXR1000, and my normal operating temp was 170 on a 70 to 80 degree day. After engine ice, I'm running 161 F on the same temperature days. My thermostat opens at 180 F, and my fans kick on at 220 (which never happens anymore, unless hitting tons of stop lights on a warmer day) so my engine is staying cooler than before. Anyway, that's my experience with it.

you have to let it run with distilled water until the thermostat opens up, which for most bikes is usually when the fan kicks on, for my zx6r it is at 214 degrees F. Running it for 30 seconds like you recommend doesnt do anything. The water will literally just sit there.

Just purchased some off Amazon. Enjoyed your video. Thanks for the info

I'll buy engine ice when im not mega poor lmao

I have not used Engine Ice so I do not know if it makes the engine run cooler or not but if it does it is not because it contains propylene glycol. Propylene glycol actually has a bit lower thermal conductivity than ethylene glycol.

Dude I love your videos I literally just bought a blue and gold Daytona 675 yesterday.

As you said. 'Propylene glycol used in Engine Ice has better heat transfer efficiency than ethylene glycol.' You should note however, that even though the two coolants have similar specific heats, boiling points and specific gravity (alone or mixed with water), that propylene glycol's viscosity is significantly (1.4 times) higher, particularly when cold (2.5 times). This means in a Ducati system - designed and sized for an ethylene glycol/water coolant - that a propylene glycol/water mixture will circulate slower and with higher pumping losses and stresses on the pump impeller and hoses .

Did your bike originally use Dexcool?

Never warm up engine before coolant change leave engine cool

Dude where are you from?, looks beautiful there. I’m in NY 😢

i don't know much about coolant ,can i use car coolant on bikes(the coolant i am talking about its color is red)?

Did the flies die?

I have a rmz450 that’s set up as a supermoto, before engine ice it was running super hot, could cook bacon at the the top of the radiators, after engine ice the radiators are just barely warm I can tell a huge difference.

Love the first gen mate I just picked one up with low mileage

Nice video. I'm new to motorcycles. I love the hills . I'm in Hermosa SD

Sick thumbnail dude!

Thanks for the Ride!!!

“Leo Vince” 😂 😂 😂

Can you mix regular anti-freeze with engine ice? I have some left over.

Nice vid. Did you say your operating temps before and after the changeover? I missed it, if so.

Imagine using distilled water during the flushing process lol

I just put some of that in my bike

Darn. I have this entire gallon of Prestone car coolant sitting right next to me. I'm going to guess that will not work with my R3. Guess Engine Ice it is 😔

U never said if engine ice runs cooler than other coolants or not and also I have heard that engine ice changes temperature pretty quickly whereas a normal coolant will not change temperatures quickly, is it true?

We live in Arizona where it is over 100 degrees most of the summer. Will Engine Ice help in out our 2007 BMW F800ST?

6:00 :)

Thank you

To be honest it looks just like Yamaha cool antifreeze!

Dam does it run cooler or not

You might’ve said it but where are these roads you’re riding on in the vid?

The Turkey was almost the national bird instead of the bald eagle...

How much engine ice will I need to buy

After how many days or km you need to refill the engine ice coolant ??

Going to buy a 675 because of your videos

Is engine ice is good to duke390 17” running in a tropical country?

Like the video but I think you A.D.D. talking about the main topic and than out of nowhere OH THATS A NICE HOUSE. 😆.

Love the video and I'm gonna use engine ice in my 2000 Honda CBR 600 F4. Would anyone happen to know how much coolant I use?

Hi, some people say that normal coolants have some kind of lubricants which help engine parts but engine ice dont have it and thats why they loose some degrees in temperature but it offers protection. whats your opinion about it.

6:50 my mouth watered 😋

Please do not heat up a bike before coolant change.

No science here! Just opinion & a link to the product?

Not a good road you picked today,lol

It does taste very sweet 😅😳

How has a deer not strode out in front of you ? Perhaps a tad slower would work to keep you riding for years to come,,, or just get enhanced Life Insurance. Love the video. Thanks for posting it.
