How Green is Your Car's Oil?
How green can a fossil fuel possibly be? The answer lies in how often you change your engine's oil. Many people stick to the 3,000 mile rule when it comes to changing their vehicle's oil. Others change their engine's oil when the oil appears black (fact: it is still doing its job, despite its sooty appearance). The number of miles you can go between oil changes varies; it depends on the make and model of your car. CheckYourNumber.org helps you calculate how often you really need to change your oil.
Changing your engine oil too frequently does not actually make your engine more efficient or extend its lifespan. In fact, all that does is drain your wallet and hurt the planet. CalRecycle reports that if all motorists in California changed their oil according the manufacturer's directions, 10 million gallons of oil would be saved every year. By taking two minutes (if that) to calculate how many miles you can drive between oil changes, you can reduce your use of fossil fuels, while saving yourself time, and money.
NOTE: CalRecycle's calculations are based on normal driving conditions. The CheckYourNumber.org website lets you know what it defines as normal driving conditions.
