What is the difference between Idemitsu Black Barrel and Gold Barrel?
2 Answers
The differences between Idemitsu Black Barrel and Gold Barrel are: 1. Different viscosity: The viscosity of Idemitsu Black Barrel is 0w20; the viscosity of Idemitsu Gold Barrel is 5w40. 2. Different grades: The grade of Idemitsu Black Barrel is SN; the grade of Idemitsu Gold Barrel is SM. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts to reduce wear; 2. To bring heat back to the oil tank and then dissipate it into the air to help the radiator cool the engine. The method of changing engine oil is: 1. Remove the engine oil filter; 2. Unscrew the oil drain bolt of the oil pan and drain the oil; 3. Install the oil drain bolt; 4. Tighten the screws, pour the engine oil into the engine, and install the engine oil filter.
I've been using Idemitsu lubricants for several years, and the difference between the black and gold barrels is quite straightforward. The black barrel focuses on being economical and cost-effective, featuring a fully synthetic SAE 0W-20 oil with slightly lower viscosity, making it suitable for daily commuting or city driving, which helps in reducing fuel consumption. On the other hand, the gold barrel typically comes in the SAE 5W-30 series, with a more advanced additive package and increased anti-wear components, offering better engine protection during long-distance drives and improved noise control. If your car is older or frequently operates at high RPMs, the gold barrel can extend the engine's lifespan. Price-wise, the black barrel is cheaper, while the gold barrel costs about 100-200 RMB more, but it's worth it in the long run, especially with current high fuel prices. Since switching to the gold barrel last year, I've noticed much smoother acceleration on highways. However, for regular family cars, the black barrel is perfectly adequate—no need to overspend. Always check the manual for the correct viscosity when changing oil to avoid mistakes.
