A: Hello there. Synthetic oil is far and away ...

Hello there. Synthetic oil is far and away better than mineral lubricating oil due to the drastic reduction in contaminants that are ordinarily left in refined mineral oil. Synthetic oil can resist much higher operating temperatures without oxidizing and breaking down and has much better flow characteristics in cold weather which reduces engine wear. During your next oil change service, which can be done at your home or office by an expert from YourMechanic, you should definitely use synthetic oil.
