Old School Versus New: Will Your Old Diagnostic Strategies Work On New Engines?
If your primary workflow consists of pre-2008 models, terms like “Gasoline Direct Fuel Injection (GDI), Homogenous Charge Compression Ignition (HCCI), Variable Compression Ratio (VCR) and Spark-Controlled Compression Ignition (SpCCI)” might sound like engine technologies lurking somewhere in the distant future.

On The Brink Of Vehicle Breakdown Season: You Play A Key Role In Keeping Customers Safe And Happy
Just knowing that the average age of vehicles on the road is 11.6 years should be music to your ears. After all, older vehicles rack up more miles, and with that comes more wear and tear. Add to that new AAA roadside research that reveals vehicles that are 10-plus years old are twice as likely to end up stranded on the side of the road compared to newer vehicles, and you’ve got the perfect storm brewing for service opportunities with the upcoming summer road-trip season, says Mary DellaValle, editor of ImportCar magazine.
