False economy

[redpoint5]

There is a reason I spend most of my forum time here instead of Diesel Truck Resource. The people here are generally brighter, and emphasize facts, mathematics, and science rather than repeating old dogma.

It's the car/truck enthusiast forums that warehouse those who can't think for themselves and make claims like "a cold air intake will improve MPG", or "my MPG improved 20% by installing a K&N filter".

Make a comment on other forums based on science, that opposes the flat-earth commenters, and you will get flamed because you don't have 20,000 posts on that forum, and don't hold the title of ASE Certified Master Mechanic.
