The April 2026 AMSOIL Price Increase — What You Need to Know
In April 2026, AMSOIL implemented a temporary surcharge across most of its product line. This was not an isolated AMSOIL decision — it is an industry-wide event affecting every lubricant manufacturer in North America.
The root causes were supply chain disruptions affecting lubricant raw materials — base oil prices increased significantly, additives were up at least 15%, and packaging costs rose sharply. Exxon Mobil, Castrol, Shell, and Chevron all announced similar increases simultaneously.
- Synthetic motor oils — surcharge of approximately $1 per quart in the US
- Fuel additives and greases — percentage-based increases of up to 16%
- The surcharge is built into the product price — no separate fee at checkout
- All other major brands increased by the same amount or more
- AMSOIL's cost-per-mile advantage is unchanged — the extended drain interval still makes it the most cost-effective option per mile driven
