Antifreeze

[Joe Camper]

I use the regular green old style and if it does not have DD on it that's OK just be sure its a low silicon type and it will be on the jug somewhere.

IMO the industry has confounded and confused the issue while lining their pockets with the extended life. And the orange and the blue or whatever ridiculous colors they have added to the field. I never did it. Cat has 2 different additive to their extended brew. One is an activator one is a extender. I still have those 2 bottles on a shelf somewhere never went that way.

So what if U need to drain it every 3 or 4 years the process is 1/5 the time needed to change over like Dale described.

DD includes the charge right in the product but U do not HAVE to use DD brand antifreeze . The additive can be purchased and added to any Green low silicon mix. U can keep it that way going forward with coolant filters with differing charge rates based on what a test strip tells U.

Another thing. IMO 50/50 mix right out of the bottle in any form is not something I never buy. I will add water from the tap instead of paying the price of antifreeze for it. amazing they can even sell that stuff and get the same money for it as 100% antifreeze.

Here is what I used in all my engines Cat DD Mack Cummins . Added this to off the shelf low silicon regular green.

On a service that Im replacing old it usually requires 10 or 12 bottles to get the mix correct. Then when doing oil changes test strip the coolant and replace the coolant filter with the correct corresponding charge that the test strips indicated. The filters come with 2 units charge or 4 units or 6 units ect ect.

Orange antifreeze ....................sheesh come on purple .......... really
