Strangest place I found peak global: my local 7-11, price: $7.95
Full concentrated gallon! The owner of the 7-11 stopped carrying it. I should see if she can still get it..
You won't find the G-05, Pentosin's, BMW, M/Benz, etc.. at big box retail parts stores. heck, autozone believes the "universal" is just that. They sell dexcool, "univesal" and old skool green (valucraft). You ask them for anything beyond what they have, and they try to push the universal on you. It's not their fault, they listen to the reps and the labels.
As BITOG members, we know better that to fall for that!
