No, I agree it's not the same company as your link. But Coast
line Chemical Inc. is also referred to as CCI,
Coastline Chemical Inc.. It's just an ironic coincidence.

but is it really worth the hassle of multiple coolant flushes and changes? most of those OE genuines are 50,000 mile minimum, and the new ones are up to 150,000 miles. and when I've called around, it's always $20 or less for the concentrate. so I guess the question is, is it worth the $8 for the peace of mind? I'd say let those automotive engineers figure this out, buy a lifetime coolant, and never have to worry about it again...
You see though many auto manufacturers recommend 2-3yr/30k subsequent intervals no matter the coolant, even OE proprietary, including Nissan green, and Toyota red is meant for that interval. So with that interval for me Peace Of Mind with the readily available full strength universals is not an issue.
I don't consider 2-3 yrs to be unrealisic or excessive flushing. I sure wouldn't try to run dexcool in a GM, or other car, for the recommended 5yr/150k.
But again, everyone should use what they are comfortable with. If dealer propriety give you Peace Of Mind, and price no factor, and you can get full strength, then that is the way to go.
