The correct synthetic oil change interval for the Amsoil signature series is 25,000 miles or 1 year, whichever comes first under normal conditions, or 15,000 miles under severe conditions. Amsoil is a pure 100% synthetic oil with superior additives that will make your car engine last longer. Mobile 1 has not stepped up to the plate to prove that they have a better product. Most car oil manufacturers will state that the recommended oil change interval is based on the car's owner's manual instead of stating a specific interval, costing you time and money. In addition to this, driving on an extended drain interval will not void your car warranty.
