Naturally Aspirated Gasoline Engine - Low Friction Energy Conserving Oil

HTHS viscosity has become the single, most vital measure of motor oil and you can tell how much an oil has wear protection and fuel economy from the HTHS viscosity alone. Notice that most modern gasoline engines don't require also high HTHS viscosity to protect against wear and you can benefit from fuel economy of small HTHS viscosities without causing significantly more wear than with larger HTHS viscosites (in normal driving conditions).
