Modern engines need oils that flow well in cold weather. Low-viscosity oils reduce friction and save fuel. Drivers see faster starts and quieter rides from them.

Viscosity grade: Look for oils like 0W-20 or 5W-30 to match your engine specs. These grades flow easily in cold and hot conditions. Check your car manual for the best fit.

Oil type: Choose fully synthetic oils for top protection and cleanliness. They last longer than conventional oils. Tests show synthetics cut wear in modern engines.

Brand and reputation: Pick trusted brands like Liqui Moly or Pennzoil from reviews. Reliable brands offer warranties and consistent quality. Read feedback from real drivers for peace of mind.

Fuel savings: Select oils that promise efficiency to lower costs. Low-viscosity options can save 2% to 5% on gas. Compare test data from brand sites.
