Best coolant
I'm running it and so is my buddy. His GTO dropped by 20 degrees in temp running this stuff. It's compatible with ALL type of coolant (dexcool, non-dexcool) plus it's non-toxic (Not that I'm a tree-hugger lol)
Lasts Longer
AMSOIL Antifreeze & Coolant contains a proprietary poly organic acid technology. It eliminates the need for supplemental coolant additives and recharging cooling systems. AMSOIL Antifreeze & Coolant provides extended service life in all gasoline and diesel vehicles. It can be used for seven years or 250,000 miles in passenger cars, light-duty trucks, vans and recreational vehicles. It lasts seven years or 750,000 miles in over-the-road diesel trucks. Also for motorcycles, ATVs, snowmobiles and closed marine applications. AMSOIL Antifreeze and Engine Coolant lasts longer than conventional products.
Compatible With Other Fluids
AMSOIL Antifreeze & Coolant is dyed neutral yellow and is compatible with all ethylene and propylene antifreeze and coolant formulations on the market, including DEX-Cool®, Sierra® and Zerex®. It is also compatible with fully formulated diesel anti-freezes and other organic acid technology (OAT) and hybrid organic acid technology (HOAT) formulations.
Stops Leaks
AMSOIL Antifreeze & Coolant adheres to metal. It self-seals hairline cracks in welds and seams to prevent leaks, without additional stop-leak products or fibrous materials.
to change your dex out, you can even do it w/o the car being put up if it's stock height. slide your head under the front on the passenger side and you'll see a drain plug. un-screw it and put a pan under it and let it drain. use a 50/50 dex and distilled water and fill her up. don't forget to tigthen that screw back up!!! if you have high mileage, might as well put a lower temp t-stat on while it's drained.

THIS IS PROBABLY ALREADY PRE-MIXED WITH A COOLANT ADDITIVE!! WHICH THEREFOR WOULD HAVE THAT BENEFIT TO BE ABLE TO ELIMINATE THE NEED FOR SUPPLEMENTAL COOLANT ADDITIVES!!! IT'S ALL BS!!!
Read my post over. Another member's GTO dropped 20+ degrees and has since been tuned and driven over 4,000 miles.
Opinion v. Actual Proof? I'll go with actual proof.
No one said that Amsoil was simply a coolant. There probably are additives in it. For $20 a bottle, I'd hope so, but IMO it's worth every penny.
And it's not premixed either. They recommend a 70/30 mix for optimal results.
See the direct link for more info on the AMSOIL Coolant with charts on mixing amounts.

we use a dex mix in our patrol cars....stuff works really well, considering we have 5000 pound cars running every electrical thing known to man, and have the a/c running at idle....

I don't drive my Z enough to worry about it, and change the coolant at least once a year. Advance Auto's pre-diluted stuff works fine and is cheap, especially on sale
