Starting a diesel truck in subzero weather puts unusual demands on its engine oil. Thick lubricant can slow cranking, delay oil flow to bearings and…

Older engines often show signs of wear that newer vehicles do not: oil consumption, minor leaks, noisy valve trains, sludge deposits, and reduced compression.…

A continuously variable transmission depends on a precisely formulated fluid to transfer power, control pulley pressure, cool internal components, and protect…

A tonneau cover can protect cargo, reduce exposure to rain and snow, and give an F-150 a cleaner profile without requiring a major investment. For many truck…

Motor oil protects internal engine parts from friction, heat, deposits, and wear. Conventional oil is refined from crude petroleum, while synthetic oil is…

When temperatures fall, engine oil becomes thicker and takes longer to circulate. That delay can increase friction during startup, when many engine components…

A tonneau cover can change how a full-size pickup works every day. It protects cargo from rain, snow, dust, and prying eyes while improving the truck bed’s…

Turbocharged engines produce strong power from relatively small displacements, but that efficiency creates demanding conditions inside the engine. Higher…
