4 â Choosing the Right Oil. Choose your motor oil based on the time of year and the climate you live in. Motor oils are designed to perform to their best throughout the seasons. In summer, choose a recommended motor oil for your particular vehicle. Have a look in the manual for your car and read the recommended viscosity suggestions for the time of year you change your oil.
By recycling your used oil you not only help keep our water supply clean, but help reduce American dependence on foreign oil. It takes 42 gallons of crude oil, but only one gallon of used oil, to produce 2.5 quarts of new motor oil. Many garages and auto-supply stores that sell motor oil also accept oil for recycling.
