Heat Ratings. The output of a radiator is measured in British Thermal Units (BTU.s) per hour. (So is air-conditioning, come to that!) 3000 BTU is roughly equivalent to a 1 kilowatt bar heater, just to give you some idea.

If you live in a place where it gets cold often, or during the winter time, you will get better results using 5w30.Otherwise 10w30 oil is good enough, i usually use 5w30 all year round.ating Newest Oldest.

The other major difference is that the 10mm uses a large pistol primer the .40 S&W uses a small pistol primer. The .40 S&W was created (more or less) to duplicate the performance of the .45 acp. The 10mm has as much power at a hundred yards as the .45 acp has at the muzzle.Nuff said!H.ence, the nickname .40S(hort) &W(eak) The two rounds fire the same projectiles, the differences between the two are that the 10mm is .142 longer than the .40S&W, and the .40 is loaded much lighter than the 10.
