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.

Demand = KW Consumption = KWH The difference between demand (KW) and consumption (KWH) is vital to your choices in reducing your energy costs. A simple way to see the difference between demand and consumption is by considering two examples.LIGHTING EXAMPLE: One 100-watt light bulb burning for 10 hours consumes 1,000 watt-hours. or 1 kWh.he difference between demand (KW) and consumption (KWH) is vital to your choices in reducing your energy costs.
