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.
Rating Newest Oldest. Best Answer: The difference between 5w30 and 10w30 is that 5w30 flows better at colder temperature. 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.

Looking at Mobil 1 synthetic oils, the differences between 0W-20, 0W-30, and 5W-30 are minimal in terms of typical inspection data. Here is a comparison of viscosity index, pour point, and flash point between the three.ooking at Mobil 1 synthetic oils, the differences between 0W-20, 0W-30, and 5W-30 are minimal in terms of typical inspection data.
