What type of engine oil should be used for the Haval H6 Coupe?
2 Answers
Haval H6 Coupe is recommended to use semi-synthetic engine oil with a viscosity of 5W-40, or higher-grade full-synthetic engine oil. The type of engine oil used in a vehicle should be determined based on the vehicle's performance and the type of engine it is equipped with. The Haval H6 Coupe is powered by a 1.5T turbocharged engine. Below are specific details about this engine: 1. The 1.5T turbocharging indicates that the vehicle's displacement is 1.5 liters, and the engine's air intake method is turbocharged. 2. The 'T' in 1.5T stands for Turbo, which represents turbocharging. Turbocharging (Turbo-Boost) is a technology that uses exhaust gases generated by internal combustion engine operation to drive an air compressor (Air-compressor). 3. Turbocharged engines available in the market rely on turbochargers to increase the engine's air intake. A turbocharger (Turbo) is essentially an air compressor. It uses the exhaust gases from the engine as power to drive the turbine in the turbine housing (located in the exhaust passage), which in turn drives the coaxial impeller (located in the intake passage). The impeller then compresses fresh air delivered through the air filter pipe and sends it into the cylinders.
I've been driving a Haval H6 Coupe for almost four years, mainly for daily urban commuting. My top choice for engine oil is fully synthetic 5W-30, from reputable brands like Shell or Mobil. At first, I didn't know much, but later learned from the manual that this type of oil ensures quick starts in cold winter temperatures, protects engine bearings, and maintains stable viscosity without thinning in summer heat. I change it every 8,000 kilometers along with a new filter to prevent sludge buildup. For frequent highway or long-distance driving, I opt for 5W-40 for better heat resistance, though 5W-30 is more fuel-efficient for general use. Always choose oils with API SN certification—low-quality oils can damage the engine. I've personally seen a friend save small money only to end up with piston wear and costly repairs. Make it a habit to regularly check the dipstick to spot low oil levels early—safety first.
