Honda Car Forum

I think that the bottom line is that in cold weather, you should spend some
more time warming the engine up then in the summer. I agree a 7-10 seconds is
fine in warm weather and maybe 15-20 seconds in cold weather.

A high performance race engine is much different then normal passenger car
engine. The stress level of running an engine at 80-100% of it's potential
for several hours is much less then cruising to work between 1500-4000 rpms
daily. Sorry NetSock but you are comparing apples to oranges.

Just curious what this has to do with warming up the engine

I disagree...please cite the studies you are referring to.

But I am not...the proof is in the pudding. Our studies were done on normal
fleet cars. I've seen the wear with my own eyes. While there is a lot of
opinion on the subject, I have yet to see any other studies or proof.

To each their own...I'm not forcing my facts on anybody...and since I cant
"show" the people here the wear, they can believe what they want. I offered
my opinion based on factual data from a controlled study, and hands on
experience. I'm not here to fight anyone.

Take care.

That's nothing. Parts of I-5 in CA get hot enough that the temp gauge
runs at 3/4 even with the winds of 85 MPH driving. You'll burn your
elbow if you bump the window. Standard 5W-30 looks like chocolate syrup
after a few long drives on that. Synthetic doesn't seem to have a
problem.

It makes you wish that they'd use light colored gravel in the asphalt
mix. Maybe some of the purple rock that's used in Lassen County asphalt.
