Recochem released a new "one size fits all, like pantyhose" All-Fleet ELC (Extended Life Coolant) this spring.
Can be used in everything from liquid-cooled snowmobiles to Peterbilt trucks.

Yes, it's a little more expensive at a little under $20.00 / jug ... but it sure is nice not having to worry about what "color" (or "flavor") of antifreeze anymore.
It was getting ridiculous. I'm also attaching Recochem's "Coolant Selection Guide" (2-pages, with page 2 being of the most interest)
