Best Answer: According to the mobil1 website your car manufacturer recommends 5W-30. It allows the oil pump to force a greater volume of oil to frictional surfaces during hot and cold starts. Low viscosity motor oil (5W-30) cools the inside of the crankcase quicker also.The oil pump turns easier, freeing-up horsepower and increasing fuel economy. It's energy conserving oil, 20W-50 is not.Take your car back to the mechanic and demand he drain the oil, change the filter and install the correct viscosity oil in the motor. Heavy-weight molasses oil in a street car spells impending death during cold starts.t allows the oil pump to force a greater volume of oil to frictional surfaces during hot and cold starts.

Germany and its allies in World War I were the first countries to adopt daylight saving time as a way to conserve energy for the war effort. Britain, other countries in Europe, Canada and the US followed suit.
Two U.S. states currently do not observe daylight saving time: Arizona (except the Navaho Nation) and Hawaii. The U.S. territories in the Pacific and the Caribbean also do notâ¦ observe daylight saving time. Until 2006 or 2007, much of Indiana did not observe daylight saving time, but that is no longer the case.
