The circulating ones are the ones that go in place of the upper radiator hose? I've seen those but wasn't sure what to think of them. Any suggestions?

Letting the thing warm up definitely kills fuel economy. Normally I wouldn't let it idle for that long, but the high just puts too much wear on all of the clutch components taking off and shifting.
