What are the differences between Helix HX7 and HX7 Plus?

[LaCora]

The differences between Helix HX7 and HX7 Plus include: 1. Different prices: HX7 Plus uses fully synthetic oil, while HX7 uses semi-synthetic oil. From the perspective of raw materials, fully synthetic oil is made from the better components of crude oil, so it is naturally more expensive than semi-synthetic oil. 2. Different performance: Engine oil is made from base oil and additives, where the base oil determines the basic properties of the lubricant, and the additives compensate for and improve the shortcomings of the base oil's performance. Therefore, HX7 Plus, which uses fully synthetic oil, performs better than HX7, which uses semi-synthetic oil.

I recently switched to Shell Helix HX7 and HX7 Plus, sharing my experience. HX7 is a semi-synthetic oil, quite suitable for daily driving, affordable, and provides basic engine protection. But HX7 Plus is its upgraded version, and I think the biggest difference lies in the additives—it has Active Cleansing Technology, which effectively prevents sludge buildup and extends the oil change interval. Officially, it can last over 15,000 km, more durable than HX7's approximately 10,000 km. In actual use, Plus offers better lubrication at high temperatures and reduces engine noise. If you drive frequently or in dusty environments, Plus is worth the extra cost. When choosing oil, always refer to your car’s manual—new and old cars have different needs.

From an economic perspective, let's compare these two oils. Over the years, I've tried both HX7 and HX7 Plus. HX7 is more budget-friendly at around 50 yuan per liter, making it suitable for cost-conscious car owners. The Plus version is slightly more expensive at over 60 yuan, but I believe it's worth it: its extended oil change intervals reduce maintenance frequency—for example, requiring only one oil change per year, saving on labor costs. HX7 Plus has superior cleaning power that minimizes wear, leading to lower long-term maintenance costs. Don't just focus on price; consider your vehicle's condition too. For those who frequently drive on highways, Plus offers greater peace of mind. Using the wrong lubricant can damage your engine, so I recommend regularly checking the oil grade to ensure it matches local temperature conditions.

When it comes to oil performance, there's a distinct difference between HX7 and Plus. I found HX7 basically adequate, but noticed more engine vibration during long-distance drives. Plus is different - its upgraded formula contains more anti-wear additives, providing smoother cold starts and better oil film stability. It also cleans engine internals more efficiently, preventing carbon buildup. Technically speaking, Plus is better suited for aggressive driving with stronger protection. Oil selection should match driving habits - HX7 works fine for suburban cruising, while Plus is better for stop-and-go city traffic to reduce failure risks.
