The Lube, Oil and Filter Market
As with everything else under the automotive sun, technology is changing the lube, oil and filter market. To be more specific, modern technology is making it possible to use the vehicle’s on-board engine management system to mathematically determine the length of an oil change interval. At the most basic level, the PCM simply adds up
BMW Performance Upgrades
When you talk about performance cars, a list of several manufacturers comes to mind. Before the explosion of Asian-made mini rockets, you needed to go European, and specifically German, to get the latest in performance machines.

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.

For that
Thermostat Technology

To better understand these functions, let’s first consider that carbon and water are two major by-products of internal combustion that accumulate in an engine’s motor oil. Unfortunately,
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.” When regular engine
Ford Timing Belts & Chains
Timing belt and chain replacement is one service that isn’t going away any time soon. Most Ford engines with overhead cam timing belts have a recommended replacement interval of 60,000 miles to 120,000 miles depending on the application (see the chart on page 54). So if a customer is driving a vehicle that is more
Diagnosing and Fixing Compressor Failures
The compressor is the heart of the refrigeration circuit. It pumps and pressurizes the refrigerant to move it through the A/C system. Compressors work hard and run hot, up to several hundred degrees and several hundred pounds per square inch of internal pressure, yet they rely on only a few ounces of lubricant to keep
