hopefully ...someone in the meantime has come up with something we can
use, and maybe it's even better. Shell has this Rotella antifreeze
that is guaranteed for the big trucks for like 150,000 miles ....
trouble is, that's only about six months in an 18-wheeler. :(
so we don't know if it'll last ten years that it would take a vanagon
to reach that miles.
my guess would be no ... that we still need to replace the
antifreeze/coolant every two years or 30,000 miles to get rid of acide
buildup and depleted additives (like anti-corrosion). :(
