Loose: 1. Not tight. 2. A colloquial term for oversteer.

Loping: Action of the engine when the mixture of gasoline and air to the carburetor is too lean.

Lorry: A British term for truck.

Loss Leaders: Products whose prices are cut with the idea that they will attract customers to the store.

Lost motion: Motion between a driving part and a driven part which does not move the driven part. Also see backlash.

Lotus: The 1958-63 Elite models are milestone cars.

Louver: ventilation slots such as sometimes found in the hood of the automobile, intended for letting air come into the passenger compartment or for cooling in the engine compartment.

Louvre: Canadian and European spelling for louver.

Low: See bull low.

Low beam: The outboard headlights in a four-light system or the main lights in a two-light system. The low beam is used for most applications of night driving. For those cars without day-time running lights, the low beam should be turned on. In fog and heavy snow, the low beam can provide more light on the road because the highbeam reflects light back to the driver.

Low bed: A low platform trailer for heavy equipment hauling, usually on 15" diameter tires. Also called low boy.

Low boy: A low platform trailer for heavy equipment hauling, usually on 15" diameter tires. Also called low bed.

Low brake pedal: A condition where the brake pedal approaches too close to the floorboard before actuating the brakes.

Low Emission Vehicle Standards: (LEV) .

Lowering kit: !!!.

Low gear: The lowest gear in a transmission, usually called first gear.

Low pivot swing axle: A rear axle setup that attaches the differential housing to the frame via a pivot mount. A conventional type of housing and axle extend from the differential to one wheel. The other side of the differential is connected to the other driving wheel by a housing and axle that is pivoted at a point in line with the differential to frame pivot point.

Low pressure indicator: A unit or combination of units which provides a visible or audible warning signal whenever the system pressure is below a predetermined value.

Low pressure tire: A tire with a large cross-section for operation at lower pressure. Increased air capacity permits lower pressure. ATV tires, for example, have only 3 or 4 psi.

Low profile: A tire with a low aspect ratio of a tire (i.e., the section height is smaller than section width).

Low tension lead: See low tension leads.

Low tension leads: The wiring in the ignition system that is distinguished from the high tension wiring. The low tension leads carry only 6 or 12 volts. Includes the battery cables, the coil connections (but not the high tension wire going to the distributor), the wiring to the ignition switch, and the non-high tension wires going to the distributor.

Low speed circuit: See idle circuit.

Low-speed circuit: See idle circuit.

Low speed traction control: See low-speed traction control.

Low-speed traction control: A system that helps prevent front-wheel spin on slippery or gravel surfaces during acceleration at speeds up to 40 kph (25 mph).

LPG: Acronym for "liquefied petroleum gas" or bottled gas or a mixture of butane and propane. In Canada, propane is the recognized term, not LPG as used in the U.S.A. Volatile petroleum gases are compressed to a liquid form. It must be kept under pressure or at a low temperature to keep it in a liquid form. It is generally less expensive than gasoline yet has high octane. It also does not create as much carbon deposit in the engine or dilute engine oil as gasoline does thus reducing the need to change spark plugs and other components as frequently. However, if not serviced and maintained properly, it can result in leakage and possible explosion. Most underground parking facilities will not accept propane powered vehicles.

Lube grease: A very thick lubricating oil that has a paste-like consistency. Used to lubricate the steering linkage, the suspension system, and other moving parts outside the engine. Also see gear grease.

Lube job: The greasing and lubrication of the suspension system, the drive train, and other parts of the vehicle which need it. A grease gun is applied to zerk or grease fittings and the grease is forced into the component. It should be done professionally once or twice a year. It can be done regularly when you change your oil.

Lubricant: Any material, usually of a petroleum nature such as grease, oil, etc., that is placed between two moving parts in an effort to reduce friction. Lubricant can also protect a part from dirt and moisture. Also see extreme pressure lubricant. Grease oil.

Lubricate beads: In order to mount a tire on a rim, the bead of the tire is coated with a vegetable base lubricant. In this way, the tire slides on easily. A petroleum base lubricant must never be used.

Lubrication: !!!.

Lubrication system: The system which stores, cleans, cools, and recirculates oil in an engine to lubricate its moving parts and bearings. It includes the oil pump, oil pan or sump, oil coolers, tubing, filters, oil passages in the block, and dashboard oil gauge. Checking the level of oil is accomplished with the oil dipstick.

Lug: 1. To cause the engine to labor by failing to shift to a lower gear when necessary. 2. A protrusion on an object. Also see dog. 3. An external metal sleeve that holds two or more tubes together at the joints of a frame.

Lug bolt: Bolts which secure the wheel to the hub. Also called "wheel lug bolt."

Luggage rack: !!!.

Lug nut: The nuts which secure the wheels to the vehicle. A lug wrench is necessary to remove the nuts.

Lug wrench: A wrench used to remove the lug nuts which secure the wheels to the vehicle. Some are L-shaped while others are X-shaped. They are usually found in the trunk of the car with the tire jack.

Luxury car: A well-appointed, well-equipped, well-designed and constructed vehicle varying in size from a compact to a large sedan.
