1981 Volvo DL, GL and GLT Service Inspection To ensure proper operation the car should be taken to a Volvo dealer between the first 600-1,200 miles (1,000-2,000 km) for a service inspection. The oil in the engine, 4-speed transmission and rear axle will then be changed. This is very important since the oil rapidly collects impurities during the break in period. pg. 35 Driving economy Economical driving does not necessarily mean driving slow Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of your vehicle to immediate traffic conditions. Observe the following rules: Bring the engine to normal operating temperature as soon as possible by driving under light load. A cold engine uses more fuel and is subject to increased wear. When possible avoid using the car for driving short distances. This does not allow the engine to reach normal operating temperature. Drive carefully and avoid rapid acceleration and hard braking. Do not exceed speed limit. Avoid carrying unnecessary items (extra load) in the car. Check tire pressure regularly - when tires are cold. Remove snow tires when threat of snow or ice has ended. Note that roof racks, ski racks, etc., increase air resistance and thereby gas consumption. Utilize the transmission to improve fuel economy. Use correct gear! From first to second gear at approx 10 mph (20 km/h) From second to third gear at approx 20 mph (35 km/h) From third to fourth gear at approx 30 mph (50 km/h) If vehicle is equipped with overdrive, use it at every opportunity (at speeds in excess of 45 mph = 70 km/h). Avoid using automatic transmission kick-down feature unless necessary. Other factors which decrease gas mileage are: Worn or dirty spark plugs Incorrect spark plug gap Dirty air filter Incorrect valve clearance Incorrect idle speed Dirty engine oil and clogged oil filter Dragging brakes Incorrect front end alignment Low tire pressure The above mentioned items and others are checked at the standard 7,500 mile (12,500 km) Maintenance file:///K|/ownersdocs/1981/81_dl_gl_glt/81DLGLGLT_02.htm (2 of 13)12/22/2006 10:28:34 PM
