Which elc are cat ec-1 rated?

[BearDZ]

I called my local Oreilly auto parts store to see if they had any cat ec-1 rated coolant that was concentrate. He said he'd have to call me back because he never heard of that. He called me back a half hour later and said that all of the extended life coolant meet the cat ec-1 rating. I don't really believe him and was wondering what you guys think. It doesn't state it on any of the gallons that I looked at when I was in there before. Anybody know?

Oreilly's carries Final Charge Global Part #FinalCharge 20.99/gal
Napa carries Zerex Extended Life Part #ZXED $18.59/gal

You may have to order the ELC, my local Oreilly's did not have FinalCharge in stock but the NAPA (large store/warehouse) had the Zerex in stock.


I know those two for sure, but Shell Rotella, CAT, and a few others make ELC too.

Has anyone tried the Amsoil elc (https://www.amsoil.com/storefront/ant.aspx) I am going to do a full flush when the weather gets warn and I was interested in my options. Also where can I get the full procedure details to do the full flush?
Thanks

If it doesn't say Cat EC-1 rated on the jug, find another brand of coolant.

I agree with Snake it does not carry the EC-1 rating, per their website and the price is higher than well known/proven ELC brands. For the flush procedures, there are a few threads further down this page & the next page. Good luck!

Amsoil glycol is a propylene base antifreeze, the same as Evans.

Most of the extended life coolants you will find don't say ec-1 and still contain the cilicates that you don't want. Like stated above, if it doesnt say ec-1 you don't want it. I had to look long and hard to find it by me. A local oil supplier had delvac ec-1 50/50 and baught 6 gal. for installation after stud job. Becouse of water dilution from the distilled water left in the system after system flush, the freeze point only tested at -7 deg.f. I had to drive to the cat shop and get two gal. of their concentrate to make the mixture correct. The stuff is hard to find.

interested as well.

would be handy to have a good list of all the know good coolants and part numbers.

i know im going to be buying my coolant soon, as soon as the restore/restore+ shows up at my door step.

Except for the fact that the Amsoil is propylene glycol based, like topdawg stated.
It is different from the other ELC's, and like Snake said, does not carry the Cat EC-1 rating. Basically the Amsoil product can't achieve that, since the Cat EC-1 rating is for ethylene glycol based coolants.
You CAN use the Amsoil coolant.
Heres the rub for both products:
Cat EC-1 is sold as premixed.
The propylene glycols are run full strength.
How do you ever achieve the true 50/50 mix when there is always around 5 quarts of water left in your coolant system after a flush? You can't add more 50/50 mix to that much water and end up with a 50/50 mix. You need concentrate. Same issue with the Amsoil (and the Evans), they should be run FULL strength, 0% (or very close to it) water. Thats not easily achieved either.
