Is HX7 Plus engine oil fully synthetic?

[SophieMarie]

New Blue Shell HX7-Plus is a fully synthetic lubricating oil, available in three viscosity grades: 5W20, 5W30, and 5W40. The specific details are as follows: 1. This engine oil is an entry-level fully synthetic oil that utilizes Flexi-Molecule instant response core molecular technology. It can operate under harsh conditions such as high temperature and high pressure, inhibiting oil oxidation and forming a protective film on friction surfaces to provide long-lasting and comprehensive protection for the engine. Whether it's turbocharging or automatic start-stop, or whether it's congested city roads or long-distance driving, HX7-Plus can handle various working conditions. 2. However, as Shell engine oil's reputation grows, counterfeit products are also becoming more common. Therefore, in addition to purchasing the corresponding oil from official stores, car owners should also verify the authenticity of the oil before adding it to their vehicles.

I was also curious before whether the HX7 PLUS engine oil is fully synthetic, so I checked Shell's official website and user manual, confirming that it's not fully synthetic but a semi-synthetic oil. Shell positions HX7 PLUS as a premium semi-synthetic, meaning its base oil is blended with synthetic components but doesn't reach the 100% pure synthetic level. If you're looking for fully synthetic oil, I'd recommend checking out Shell's HX8 or Ultra series, which are true fully synthetics. HX7 PLUS has its advantages—it's quite cost-effective, sufficient for daily driving, and offers better cleaning performance and durability than conventional mineral oils, making it especially suitable for urban commuting. I've used it once myself and found it good for fuel consumption control, though the oil change interval isn't as long as with full synthetics. Don't worry about the brand misleading you—today's engine oil market is transparent with information. Before buying, comparing the API standards or viscosity grades labeled on the packaging can save you a lot of hassle.

As a mechanic who frequently works on cars, I can confirm that HX7 PLUS engine oil is not fully synthetic. It belongs to the semi-synthetic category, where some synthetic technology is used in the base oil, but it doesn't completely replace the mineral components. Shell's design is to grade the HX series, with HX7 PLUS in the middle tier—better than conventional mineral oil but a step below fully synthetic oils like HX8. In terms of performance, it offers good wear resistance and anti-deposit properties, providing solid engine protection at a high value. If you're after ultimate protection, fully synthetic oils are more stable under high temperatures or during long-distance driving. Using the wrong oil isn't a big deal; just check the dipstick regularly for color and level, and don't wait for the warning light to come on. I've seen many car owners damage their engines by using the wrong oil—nowadays, checking car forums for feedback makes it easy to get the right information.

HX7 PLUS engine oil is not fully synthetic, it's Shell's semi-synthetic product. In my opinion, the highlight of this oil lies in balancing price and performance, making it suitable for most family cars. The synthetic components enhance its cleaning ability, resulting in smoother engine operation. If you frequently drive on highways or own a high-performance vehicle, fully synthetic oil would be more durable and reduce oil change frequency. From my past experience with car maintenance, I've found that the most reliable indicator on oil labels is the 'fully synthetic' wording - since HX7 PLUS packaging doesn't state this, it isn't. Don't just believe advertisements; what matters is the minimal change in fuel consumption during actual use.
