Oil is the lifeblood of your engine. By changâ€" ing it regularly you can extend engine life and avoid major repair. Fortunately, it is one of the easiest mainteâ€" nance tasks. 1. Warm up the enâ€" gine so that the full load of dirty oil will drain from the pan. Heat thin oil, allowing a ready flow. Converâ€" sely, cold oil is thick. Some may remain in the engine. 2. Lift the front of the car or leave all four wheels on the ground. If you lift the vehicle, support its weight on safety stands. Do not work beneath a car which is supported only by a jack. Accidents happen. Engage~the parking brake; place an automatic transmisâ€" sion in PARK and a manual transmission The wrench should fit exactly to avoid damage, making plug removal difficult.

Place a drain pan (sixâ€"quart capacity) under the drain plug and loosen the plug with an adjustable, box, openâ€"end or socket wrench. Whichever one you use, make sure it fits the plug snugly to avoid damaging the plug. 4. Remove the looâ€" sened plug by hand. To avoid burning your fingers, be ready to draw your hand back quickly as oil begins Nowing. Allow oil to drain completely. This takes about three minâ€" utes. 5.

However, to be effective, ‘the gasket must be in good condiâ€" tion. If it isn‘t, replace it. â€" 6. Thread the drain plug into the oilpan (don‘t cross threads) and tighten by hand. Then, using a wrench, tighten the plug snugly . Do not overtighten. You may distort the vilpan. 7.

This means the oil is intended for SE use, but, obviously, also fulfills the needs of SD and SC use. W hen economic indicaâ€" tors suggest the sky is falling, it‘s prudent to seek the shelter of a Volvo DL station wagon. A Volvo‘s durability (average life expectancy in Sweden is 18.7 years) means you shouldn‘t have to return to the money market for a newâ€" car loan for some time. And as your family grows, you won‘t have to replace your Volvo wagon with a larger car. The DL comfortably seats five adults. There‘s even an optional third seat in back for late arrivals. Best of all is the feeling you get from knowing Volvo is designed with safety in mind. Ask your Volvo dealer to point out all the safety features built into the DL wagon. Then, be your own securâ€" ity analyst. You‘ll probâ€" ably end up selling your car and buying ours. VOLVO 1981 VOLVO CANADA LTD A car you can beheve in the Society of Automoâ€" tive Engineers (SAE) that designates the reâ€" sistance of oil to flow. Thick, slowâ€"flowing oils have high numâ€" bers; thin, freeâ€"flowing oils have low numbers. The W following a number means that the viscosity was deter mined at OF. and the oil is intended for use in cold weather. If there is no W, viscosity was determined at 210°F., and the oil is intended for use in w arm weather. Oils with two numâ€" bers, such as SAE 20â€" W40, have the ability to change viscosity as temperature changes, being light enough to allow easy engineâ€" starting in cold weather, yet heavy enough to provide proper engine protecâ€" tion at high temperaâ€" tures. e VOLVO e MAZDA e BMW
