Amsoil synthetic motor oils for auto and lite trucks come in three grades.

Amsoil Signature Series
 Amsoil Signature Series synthetic oil is Amsoils top grade synthetic motor oil.  Amsoil signature series most popular is 5w-30 oil, but Signature Series comes in many viscosities to meet the requirements of most manufacturers, Oil drain intervals are 25,000 or one year in all Signature Series viscosities.  This drain interval is not new Amsoils first synthetic oil supported 25,000 drain intervals way back in 1972.  Amsoil was the first full synthetic oil on the market and today Amsoil is known as the leader in synthetic lubrication.

Amsoil XL (Extended Life)
  Amsoil XL offers the same engine protection as Amsoil Signature Series but with a shorter drain interval.  Amsoil XL is engineered for a drain interval of 10,000 miles or 6 months.  As with the Amsoil Signature Series, 5w-30 oil is most popular but XL comes in many viscosities to meet most manufacturers recommendations.   In research Amsoil discovered even today, extended oil drian intervals are hard to accept for some even though manufacturers suggessted drian intervals are in the area of 5,000 to 10,000 miles.  Many still follow the 3,000 mile oil drain intervals common for older conventional oils.   The extra additive package in all Amsoil full synthetic oil effectively raises the total base number (TBN), a measure of an oil's useful service life, and provides superior protection and performance throughout the entire drain interval. 

Amsoil OE (Original Equipment)
 Amsoil Original Equipment engine oil is for those that feel more comfortable following the manufacturers suggested drain interval stated in the auto or truck owners manual.   As with the Amsoil Signature Series and XL, 5w-30 oil is most popular but XL comes in many viscosities to meet most manufacturers reccommendations.   AMSOIL OE Synthetic Motor Oil is specially formulated for the longer oil change intervals recommended by vehicle manufacturers today. Its advanced synthetic technology resists chemical breakdown for maximum wear protection (and peace of mind) well beyond the traditional 3,000-mile oil change interval.
