Tech Tip: Spark Plugs & Wires – Producing the Spark that Keeps the Engine Humming

Maintenance intervals on late-model vehicles have been stretched to the limit, and spark plugs are no exception. Most original equipment spark plugs today are long-life plugs with a recommended replacement interval of 100,000 miles or more. To some motorists, that means never.

Tech Tip: Flushing Away Engine Problems

When motor oil isn’t changed often enough, varnish deposits and sludge begin to form inside the engine. If the oil is neglected long enough, it will eventually turn into goo and ruin the engine.

Tech Tip: How Engine Oil Becomes Engine Sludge

Fresh engine oil is a clear, free-flowing liquid blend of base stock and additives that contains no fuel, water, coolant, dirt or other contaminants. In engines that have failed prematurely, the oil has very often been transformed into a high viscosity deposit of brown or black goo, commonly referred to as "sludge."

Vehicle Mileage Maintenance

A mere 0.7 of a mile does not sound like much, it is about 3,700 feet, or less than one-third the distance around Daytona International Speedway. On average, the U.S. population of vehicles will get 20 miles per gallon (including light trucks and passenger vehicles). A 0.7 of a mile improvement represents only a 3.5

Flushing Away Engine Problems

When motor oil isn’t changed often enough, varnish deposits and sludge begin to form inside the engine. If the oil is neglected long enough, it will eventually turn into goo and ruin the engine. “Oil sludging” has become a serious problem in recent years for a number of reasons. One is that more new car

Preventing Oil from Turning to Sludge

Fresh engine oil is a clear, free-flowing liquid blend of base stock and additives that contains no fuel, water, coolant, dirt or other contaminants. In engines that have failed prematurely, the oil has very often been transformed into a high viscosity deposit of brown or black goo, commonly referred to as “sludge.” When regular engine

Confronting the Complete Cooling System Service

By now, it’s obvious to most service shops that cooling system service is an absolute “must-do” on any nameplate. Once a cooling system suffers long-term neglect, it turns into an ongoing source of problems for the owner and his service technician because, when corrosion starts to take place, the effects can’t be reversed. For that

Getting “Tuned” Into Exhaust System Service Opportunities

Although stainless steel exhaust systems have reduced the number of exhaust system replacements, it’s important to remember that regular exhaust system inspections remain an integral part of import service. When inspecting an exhaust system, remember that the exhaust pipe and muffler must: Help “tune” the engine for peak performance;   Reduce noise to legal levels;

ls, appear to be the next generation of fuel injection for gasoline engines. The reasons for implementing this technology are legislative, and also include market requirements that drive the need to reduce fuel consumption, while at the same time, meet the increasingly stringent exhaust emissions regulations. According to engineers at Delphi Corp., gasoline direct injection
