I changed my fluid at 154k. Oddly enough, it was still pretty clean when we drained it. But afterwards I switched to this Liquid Chill Synthetic Engine Coolant

It's pretty solid stuff, certainly after a day of the car getting used to it I noticed the way my engine responds. The flatspot at 4k seems to be completely missing. It accelerates better, climbs hills in higher gears like it's new. So overall major boost to the cooling system. I highly recommend it for our cars.

What engine do you have? Do you have before and after engine temperatures or you're just going on seat of the pants feel?

This is Mishimoto's take on RP's ICE & Redline's Water Wetter, I suppose. If one can totally extract the old coolant , Evans Waterless Lifetime Coolant may be the superior option.

is temperature control an issue on our cars?

Nope, but extending radiator life is a plus. PH in coolant changes over time, so w/ its efficacy. Evans Waterless is a product that addresses all the above.

Is radiator life a problem with the Mazda specified coolant and change intervals?

Nah, but if one plans to keep the car long term & wishes to have 1 thing less to do & worry about, there is that coolant upgrade option.

I have a request. I'd like you to measure the voltage across the coolant if you're willing.

The only thing I'm personally interested in is prolonging life if the rad since I plan to keep this car a long time.voltage is an indication of how fast corrosion iis taking place.

So its simple. A range down to 0.01 will suffice. With the engine cold, take off the rad cap. Place the positive lead of a multimeter into the coolant without touching the rad itself. Put the negative lead on a ground such as a bolt head any we on the frame.

This should give us a rough comparison to the OEM coolant.

I have the 2.5 motor.

Mainly seat of pants feel, but I do 200 miles of driving a day so I'm likely to notice changes in the way the engine behaves. It's a lot smoother overall in the revs, the hill climbs are much better as it's got a noticeable increase in tq in the low revs. Gas mileage seems to have certainly improved when cruising at higher speeds above 70mph.

I use the 20% coolant. Then half bottle water wetter and water. AND WORKs fine in the caribbean

The only thing I can think of that would cause such improvements is the new coolant is slicker and/or thinner, thus causing the engine to suffer less resistance when turning the water pump. This would be similar to the effect of using a slicker and/or thinner oil.

About the only way to prove the improvements would be measuring the before and after effects; e.g. the ETs of a 0-60 acceleration run, a controlled course using measured fuel amounts, putting the car on a dynamometer, etc.

For longer term longevity effects, that takes years unless some presumed factors are employed, such as acidity, anti-corrosive ingredients compared with other mixes, etc and etc.

And then there's the faith element.
