How often should Shell HX7 Plus engine oil be changed?
2 Answers
Shell HX7 Plus engine oil has a relatively short oil change interval, possibly requiring replacement every six months or so, but the specific time should be determined based on actual conditions. Here are the relevant details: 1. It adopts Flexi-Molecule technology, which enables it to work under harsh conditions such as high temperature and high pressure, inhibiting oil oxidation and forming a protective film on friction surfaces to provide lasting and comprehensive protection for the engine; 2. Shell HX7 Plus engine oil comes in three viscosity grades: 5W20, 5W30, and 5W40. It is an entry-level fully synthetic oil, but compared to semi-synthetic oils, it offers superior performance and an overall better driving experience.
I often use Shell HX7 Plus oil for my car, feeling it's a semi-synthetic oil, so the oil change interval shouldn't be too rigid. Changing it every 7,500 to 10,000 kilometers is reasonable. If road conditions are poor, like city traffic jams or dusty environments, it's better to shorten the interval to around 7,000 kilometers. Remember to check the oil level regularly. If the oil is too dirty or becomes thin, change it earlier to protect the engine from excessive wear. Personally, I check the dipstick every three months and maintain a service record, which helps the car last longer without unnecessary expenses. The manufacturer's manual usually recommends changing every six months or by mileage—don't push it too far. Otherwise, the oil's performance declines, lubrication suffers, the car starts sluggishly, and fuel consumption increases—what a hassle! Developing good habits saves you from costly major repairs and keeps your driving worry-free.
