Amsoil synthetic motor oil protects your car engine because it doesn't break down or lose it's viscosity under extreme temperatures and stress. Regular conventional oil breaks down under high temperatures which leaves harmful carbon and sludge deposits which will make your engine wear faster. This is why you have to change your motor oil every 3,000 to 5,000 miles or so at your local dealer or quick lube business which costs you more money over the long term!
Research shows that synthetic oil is superior to conventional motor oil! Source: AAA research proves that synthetic oil is better than regular conventional oil report
