anybody tried the local truckstop antifreeze?
shell makes one called Rotella (same name as their long-life motor
oil)
that has claims of 600,000 miles (in a truck) or 12,000 hours.

and
http://www.rotella.com/products/rotella-elc.html

now the Gotchas ... 600,000 miles in an 18-wheeler is ...<drum
roll>...
about two years. hmmm. just about the interval we're supposed to be
replacing our antifreeze anyway! ;) maybe just a co-inkydink.
i do notice that the blurbs mention that you do NOT have to have a
filter
on the cooling system, and in fact, mention that you should bypass the
filter
when using this product.

anyway, nobody mentions how much it costs. if it's cheap enough,
it might be a local supply that we could use. most towns have some
sort of truckstop or truck repair place nearby.

anybody tried it?
