I'm often asked about extending drain intervals using Amsoil synthetic motor oils so let me address that question here. Yes you can significantly extend your drain interval using Amsoil Synthetic Motor Oils. AMSOIL has recommended 25,000 mile/one year drain intervals since 1972. AMSOIL delivers the highest quality lubricants on the market. It’s the AMSOIL identity, and it’s what customers expect. Al Amatuzio coined the phrase “extended drain interval,” and from the beginning, AMSOIL synthetic motor oils have been formulated for extended drain intervals.

Vehicle manufacturers are pushing for extended oil drain intervals. Vehicle manufacturers in Europe have been recommending extended oil drains for years. In fact, the average drain interval in Europe is 10,000 miles. Vehicle manufacturers in the United States are definitely coming around to extended oil drains as well. Most owners manuals
from recent model vehicles recommend 5000 to 7500 mile oil drain intervals. In addition, oil life monitors have become increasingly common on today’s vehicles, allowing and encouraging motorists to increase drain intervals up to 12,000 miles, even when using conventional oil. Vehicles equipped with an oil life monitor no longer recommend oil changes based solely on mileage. The system measures engine operational data such as temperature, revolutions and speed to determine when the oil is nearing the end of its life.

The motor oil industry is faced with the extended oil drain interval issue. The success of oil life monitors has posed a threat to motor oil companies who insist oil must be changed every 3000 miles. It becomes increasingly difficult to maintain this position when vehicle manufacturers are recommending significantly longer intervals with the use of their oil monitoring systems No doubt this is one of the reasons ExxonMobil finally introduced a line of long drain motor oils.

AMSOIL products are available for less. The suggested retail price of the top oil in ExxonMobil’s new line, Mobil 1 Extended Performance, is $5.79 to $5.99 a quart. That’s right in line with AMSOIL 5W-30 and 10W-30, which retail for $5.95 a quart. By registering as an AMSOIL Preferred Customer, customers can pay only $4.65 a quart, and even less when purchasing by the case.

Clean engine formula. Resists high temperature break down that forms sludge and varnish. Lasts longer and offers better protection. Ideal for hot and cold climates.
