Your engine’s oil is it’s life blood. Proper maintenance and regular oil changes helps your engine stay in good operating condition. We recommend changing your oil every three months or three thousand miles (3 months / 3,000 miles) which ever comes first for most daily driven vehicles. Some vehicles have different service and maintenance intervals. If you are not sure what your vehicle needs, bring it to the trustworthy professionals at Coastal Tire and Auto Service. Every automobile manufacturer establishes recommended oil change intervals for each model they manufacture. Some oil change intervals are 5,000-7,500 miles for many new cars. You should follow your car manufacturer’s recommendations on oil change intervals while the car is under warranty. If your car is no longer under warranty, you can extend your oil change intervals by upgrading to synthetic motor oil. There are a number of quality synthetic motor oils available to choose from. Most lubricant manufacturers will give a recommended number of miles you can drive between oil changes under normal conditions. The number of miles you can allow between oil changes will depend on the way you drive and the oxidation stability (useful oil life) of the motor oil. Call or stop by the shop for more detailed service and maintenance information for your vehicle.
Useful information about motor oil:
The viscosity (or thickness) of single-grade oil derived from petroleum unimproved with additives changes considerably with temperature. As the temperature increases, the viscosity of the oil decreases. On single-grade oils, viscosity testing can be done at cold, winter (W) temperature to grade an oil as SAE number 0W, 5W, 10W, 15W, 20W, or 25W.
The temperature range the oil is exposed to in most vehicles can be wide, ranging from cold temperatures in the winter before the vehicle is started up to hot operating temperatures when the vehicle is fully warmed up in hot summer weather. A specific oil will have high viscosity when cold and a low viscosity at the engine’s operating temperature. The difference in viscosities for any single-grade oil is too large between the extremes of temperature. To bring the difference in viscosities closer together, special polymer additives called viscosity index improvers, or VIs are added to the oil. These additives make the oil a multi-grade motor oil.
10W-30 designates a common multi-grade oil. Historically, the first number associated with the W (the ‘W’ is for Winter, not Weight) is not rated at any single temperature. The “10W” means that this oil can be pumped by your engine as well as a single-grade SAE 10 oil can be pumped. The second number, 30, means that the viscosity of this multi-grade oil at 100°C (212°F) operating temperature corresponds to the viscosity of a single-grade 30 oil at same temperature.
