Top 10 Most Common Vehicle Repairs

Basic maintenance is the key to keeping a car running at its best. When motorists keep up with fluid changes, tire checks, filter changes and other services, it helps avoid bigger and more expensive repairs down the road. However, over time, some vehicle parts and components wear out or become damaged. When motorists are educated about their vehicles’ maintenance needs, it allows them to address any issues before they become even bigger problems.

ACEA Oil Specifications: New ‘Sequences’ Mean Better Oil Performance Characteristics

ACEA standards are based on testing developed by the European Engine Lubricants Quality Management System (EELQMS). Think of ACEA as the SAE of Europe and EELQMS as the API/ILSAC in the U.S.

Timing Chain Stretch: It Could Be Neglected Oil Changes And The Wrong Oil

Timing chain stretch is not the stretching of the timing chain, it is an elongation of the timing chain caused by wear to the chain’s components. The most common cause of timing chain stretch is lack of maintenance and regular oil changes.

Oil Level Sensors – More Than A Warning Light

Oil level sensors have been used on import and domestic cars for more than a decade. Some of the first applications only monitored if the oil level was low using a switch attached to a float. The sensor would just trigger a message or light in the instrument cluster and only measured oil levels when the engine was not running.

What Is Oil Testing?

Oil specifications are not about the ingredients in the oil, but how the oil reacts to standardized conditions.

The Evolving Oil Change Market

The only constant in the oil change business is change itself, especially if you’re trying to maintain an inventory of engine oil for all makes and models of vehicles.

Engine Oil Specifications 101

Engine oil can be one of the most confusing and controversial products to select for a vehicle. The reason for this is that engines are becoming more stressed and require lubricants with specific attributes to protect and power gasoline engines with turbochargers, direct fuel injection and advanced internal components.
