Which AMSOIL tier is best for my vehicle?
This can be a tricky question that can depend on quite a few variables including: cost, value, oil quality and extended drain interval expectations. The best way to start the discussion is to introduce the 3 tiers of AMSOIL synthetic oils available:
- Signature Series = The top tier product that has a drain interval of up to 24,000-km/1 year
- Extended Life (XL) Series = API certified middle tier product for those that prefer to change their oil twice a year with a drain interval of 16,000-km/6-months
- Original Equipment (OE) Series = API certified introductory tier with the lowest cost synthetic in the AMSOIL line for those interested in trying AMSOIL products and maintaining manufacturer warranties by using the drain interval specified by the equipment manufacturer
