Our suppliers try to provide the best quality oil seals and products are in some cases optimised to improve performance and fitment. Corteco is one of these brands, whose case studies we have listed for you.
Choosing the Right Oil Seals:
Because synthetic motor oil can cost two to four times more than regular oil, talk to your technician about whether it’s the right oil for your car. If you live in a climate with super cold winters or very hot summers, or use your vehicle for towing or hauling, synthetic oil may be the best type of oil for your vehicle. Older engines could also benefit from synthetic oil, as it can help prevent harmful sludge build-up that some older engines seem to be prone to.
Oil seals are used in a great many machines.
