What Is Oil Testing?
Oil specifications are not about the ingredients in the oil, but how the oil reacts to standardized conditions.
Flex Fuel: Ethanol vs. Gasoline
For political and economic reasons, the use of ethanol gasoline in the U.S. has always been controversial.
Ride Of The Week: 1984 Hurst Olds Named Sorceress

Ride Of The Week: 1957 Echarger Pontiac Chieftain Catalina Hardtop
Jonathan Goodwin of H-Line Conversions is the owner of a racy looking 1957 Pontiac Chieftain Catalina Hardtop that’s equipped with a prototype version of his Echarger, a device bolted on the car’s engine that improves its fuel efficiency and reduces harmful emissions.
Top 10 Fuel Pump Fails
Ten problems to be aware of when a vehicle’s fuel pump fails.
Contaminated Fuel Can Wreck Havoc On Fuel Delivery Systems
Although cases involving contaminated gasoline are relatively rare nowadays, they still occur. In many cases, the technician has replaced the fuel pump or mass air flow (MAF) sensor to address a P0171/P0174 “lean-condition” DTC with no result. In all likelihood, the technician didn’t consider the possibility that the vehicle’s fuel might be contaminated with E85 gasoline, diesel fuel, stale gasoline, or, to a lesser degree, sugar and water.
Engine Bearings Under Pressure
Engine bearings have to withstand punishing loads in today’s engines. Smaller displacements, turbocharging and higher horsepower ratings mean crankshaft and connecting rod bearings are being subjected to heavier loads. This has led to the development of some new bearing alloys and coatings that enable these parts to survive.
Fueling Choices: Factors For Carburetion Or A Bolt-On TBI Fuel Injection System
If you’re building a performance engine, should you fuel it with a carburetor or some type of electronic fuel injection (EFI) system? If the application is a late-model vehicle that came factory-equipped with EFI, that decision has already been made for you.
Import Oil Specification Primer
As engine technology has evolved and fuel efficiency standards have tightened, oil specs have increased in importance. Using the wrong viscosity could set a fault code in some applications or interfere with the normal operation of the variable valve timing system.
Tech Tip: BMW TPMS Systems
BMW has offered Tire Pressure Monitoring Systems (TPMS) on most of its vehicles since 2002. Some 2002 and 2003 models have an indirect system called Flat Tire Monitor (FTM) that compares the inputs of the wheel speed sensors to detect a flat tire. These early indirect and direct systems were implemented not to meet the
