### Tool changes

- 2026-10-17 `suggest_for_vehicle` added
  - Matches the viscosity grade and specification a vehicle's owner's manual lists to AMSOIL products, with shopping links carrying dealer referral zo=30734402 and the official AMSOIL lookup link for confirming the exact fit. It does not look up vehicles: give the requirements from the manual. Without them it returns questions to ask (needs) instead of guessing.

- `nearest_distribution_centers`: The three closest AMSOIL distribution centers in the same country as a U.S. ZIP code or Canadian postal code, by straight-line distance. These are AMSOIL facilities, not A1 locations, and the nearest one may not fulfill an order.
