We have great suggestions on making sure your engine is running perfectly. Check out this week's maintenance tips!
1. Heavier is not always better
Use the oil viscosity grade that’s recommended in your owner’s manual for the temperature range you expect for the coming season. Lighter grades (lower viscosity, such as SAE 5W-30), often specified for today’s smaller car engines, will deliver easier starts and better engine protection in winter and improved gas mileage throughout the year, thanks to less internal engine friction. Do not use a heavy grade of oil in cold winter climes or you will risk damage to your engine.
2. Maintain your transmission
Change automatic transmission fluid and filter after the first 5,000 miles (8,000 km) and after every 25,000 miles (40,000 km) or two years thereafter, or as recommended in your owner’s manual. If you use your vehicle for towing, change the fluid and filter every year. For manual transmissions, change the lubricant (motor oil or gear oil, depending on the car) after the first 5,000 miles and after every 50,000 (80,000 km) thereafter. Use synthetic motor oil or gear lube for longer transmission life unless the manufacturer recommends otherwise.

3. Consider adding oil coolers
If you plan to do a lot of towing and your vehicle is not already equipped with coolers, consider having them added. Aftermarket engine oil and transmission fluid coolers are simple, low-cost addons that operate on the same principle as your car’s radiator. The fluid flows through them, and many small fins absorb and dissipate heat. Cooler operating temperatures of engine oil and transmission fluid can add significantly to the life of your engine and transmission.
4. Spark plugs do need changing
The advent of electronic ignition and on-board computers has eliminated the need for regular tune-ups, but you still need to change your spark plugs. Many manufacturers recommend changing plugs every 30,000 or 40,000 miles (48,000 or 64,000 km) to ensure good fuel mileage and engine performance. Some new cars come with long-life plugs (sometimes called double platinum plugs) that can last for 100,000 miles (160,000 km). If your car isn’t so equipped, make the switch after 30,000 miles. The extra cost is only a few dollars per spark plug. While you’re at it, change your spark plug wires as well. Their typical life is 50,000 miles (80,000 km). Deteriorated wires can cause those high-tech new spark plugs to foul.
5. Avoid hose hassles
Check the hoses under your hood every month or two to avoid the hassle of a broken hose while you’re on the road. With the car cool and off, squeeze the hoses. If they are hard or make a crunching sound, replace them. Ditto if they are extremely soft or sticky.With the car warm but off, examine hoses for bulges and collapsed sections. If you find any, the hose walls are weak, and it’s time to replace the hose. Never drive with a ruptured coolant hose, or you are liable to overheat the engine and damage it. Other hoses are crucial to operation of your power brakes and cruise-control systems.
