AMSOIL 0W-20, 5W-30 and 10W-30 Synthetic Motor Oils join AMSOIL Signature Series 0W-30 to round out the new Signature Series line. The new Signature Series line features all-new packaging and represents the very best motor oils AMSOIL has to offer, allowing motorists to take advantage of maximum extended drain intervals. These Signature Series oils are recommended for drain intervals of up to 25,000 miles/one year, whichever comes first (15,000 miles/one year in severe service conditions).

With the recent introduction of AMSOIL OE Synthetic Motor Oil made for original equipment manufacturers recommended drain intervals and the recent reformulation of XL Synthetic Motor Oil, made for twice a year oil change, now the AMSOIL Signature Series with its 25,000 mile or one year oil change provides motorists with three distinct lines of high-quality synthetic motor oil, appealing to every customer’s need.

In addition to being reformulated to meet the latest API SN Resource Conserving and ILSAC GF-5 industry specifications, AMSOIL Signature Series 5W-30 is recommended for the new GM dexos1 specification.
