How often you change your motor oil depends on a number of things:
The type of vehicle you drive
The amount of stop and go traffic you drive in
Humidity and condensation
The existing wear and tear already on your engine.
The type of oil you use.
The better grade of oil you use the better it will hold up. Older vehicles burn more gas and build up more carbon deposits in the oil. Most new models are more fuel-efficient and burn less gas.
When you drive a vehicle that averages gas mileage of 1 – 20 miles per gallon, and that’s a lot of gas, you get a lot of carbon. Oil manufacturers recommend changing your oil every 3000 miles.
Now a lot of our newer model vehicles are designed to be more efficient at burning fuel. The objective of burning gasoline better is less carbon monoxide. So with newer vehicles getting gas mileage of 25 miles per gallon or better, oil manufacturers recommend changing the oil every 5000 miles.
OK, how about synthetic oil?
Synthetic oil is designed to better lubricate and better dissipate heat. Using synthetic oil, according to oil manufactures, will add about 2000 miles to an oil change, and that is a standard rule of thumb.
Now the thing to know is this – most engines designed after the year 2000 are more efficient at burning gasoline and in the operation of the internal workings of the engine. Lighter softer metals and closer tolerances in most late-model vehicles are designed to use only synthetic oil because it does lubricate better and dissipates heat better.
So, my point is this. Get with the people that care for your car, figure out what the best schedule is to change the oil in your vehicle, and stick with it! And remember to have the tire air pressure checked and corrected at every oil change!
Invest in preventative maintenance by spending a little money every few months and keep your car running safely and efficiently, and help prevent those big-ticket items such as replacing an engine.
