How often should Castrol EDGE oil be changed?
2 Answers
Under normal circumstances, Castrol EDGE should be changed once a year or every 10,000 kilometers, as it is a fully synthetic engine oil. For more details, please see below: 1. Oil change frequency: Normally, fully synthetic oil should be changed every 10,000 kilometers or about one year, semi-synthetic oil every 7,500 kilometers or about nine months, and mineral oil every 5,000 kilometers or about six months. Time or mileage, whichever comes first. 2. Introduction to Castrol EDGE: The Castrol EDGE series is the top-tier fully synthetic engine oil from Castrol, all of which are SN-grade, on par with Mobil 1 and Shell Helix Ultra. Castrol EDGE comes in four viscosities to meet different driving condition requirements. The four viscosities are: 0W-40, 5W-40, 5W-30, and 10W-60.
I've been using Castrol Edge oil for several years and feel that oil change intervals should be determined by individual driving habits. Generally, for full synthetic oils like Edge, manufacturers recommend changing every 10,000 km or 12 months, but this is just an average. For example, since I mostly drive on highways with stable oil temperatures, I can stretch it to 12,000 km. But if you frequently encounter city traffic jams with constant stop-and-go driving and high engine loads, the oil degrades faster, so it's better to change at 8,000 km. Hot summer conditions or dusty roads also warrant earlier maintenance. Don't just focus on mileage - if the car hasn't been driven for over six months, the oil should be checked. I recommend regularly inspecting the oil color and viscosity using a dipstick or oil quality monitor, which saves both hassle and money. Keeping your engine healthy extends your car's lifespan and avoids major repair headaches.
