Gearbox oil works in similar way to other oils in that it lubricates the gearbox, resulting in a smooth and comfortable ride.
Transmission oil helps to keep both your gears and transmission systems in top working order, and it's recommended to change your gear oil every 50,000 to 100,000 miles to help prolong the life of your gearbox, as well as to continue making gear changes feel smooth.
Your power steering system needs to be kept topped up with power steering fluid to ensure it's working at its best and to keep all of the components moving smoothly and freely.
Its important to choose the correct oil or transmission fluid for your particular vehicle, as they can vary so much. We stock a wide range of brands such as Castrol oil and Comma oil, so you shouldn't have any problems finding the correct oil for your car.
