Why so? I find that my Tannis does a pretty good job after and hour or
two.
After all, you don't have to get the engine up to operating temp. If I
have
raised the engine temp 20 or 30 deg I have done a lot of good.


Same with my Reiff. But around here, quite often, raising the temp 20
degrees would still not have it above freezing. :~(

Every little bit helps, even the old "light bulb in the engine compartment".
Thanks, but as so many have pointed out, you do more damage to an engine in
the first minutes of a very cold start than in 100 hours (or so) of cruising
at high speed.

For a turbo'ed (or turbonormalized) plant, the effect can be even more
devastating.

It's also nice to come into an engine compartment that's 80 degrees and have
the cabin heater kick out nice warm air from the 'git go.



Once again, every little bit helps.
