The Difference Between Shell Blue Drum and Gray Drum
2 Answers
The differences between Shell Blue Drum and Gray Drum are as follows: Different Properties: Gray Shell is fully synthetic oil. Blue Shell is semi-synthetic oil. Different Oil Quality In terms of oil quality, Shell's gray oil is the best. The grade of Gray Shell oil is higher than that of Blue Shell oil, so in terms of price, Gray Shell oil is also slightly more expensive than Blue Shell oil. Different Uses: Gray Shell oil is more suitable for vehicles with turbocharged engines and medium-sized luxury cars, while Blue Shell is suitable for most compact and medium-sized vehicles. However, if the car's engine is not precise enough, fully synthetic oil is not as good as semi-synthetic oil.
I've used Shell's blue and gray barrels several times. The blue barrel refers to the Helix HX8 series, and the gray barrel is the Ultra series, right? The blue barrel is significantly cheaper, saving me dozens of yuan per oil change. It feels like the engine noise is slightly louder when driving, but it's perfectly adequate for daily commuting, and fuel consumption is well controlled. The gray barrel is more expensive, but the performance improvement is noticeable, especially with faster and smoother engine response during acceleration, and better stability at high speeds with less engine heat. The biggest difference is that the gray barrel uses better fully synthetic base oil, providing stronger engine protection and extending the oil change interval to nearly 10,000 kilometers, whereas the blue barrel might start getting noisy after 6,000 to 7,000 kilometers. If you have a new car or frequently drive long distances, the gray barrel is worth the investment; otherwise, the blue barrel is more economical.
