Synthetic oil is a great way to go and can save you time, money and gas. It’s a good choice for high output, turbocharged or supercharged engines, vehicles that are used for towing (especially during hot weather), and vehicles that are operated in extremely cold or hot climates. Though more expensive than mineral-based motor oils, synthetic oil can improve fuel economy. You also have longer intervals between changes which saves on time and ultimately will actually cost you less that mineral-based oil changes.
