What warranty/guarantee does AMSOIL offer?

AMSOIL backs its products with a limited warranty/guarantee that covers engine repairs under specified conditions and time/mileage limits per the official policy. Review current terms on AMSOIL.com.

Will using AMSOIL void my vehicle warranty?

No. Using AMSOIL does not automatically void your warranty. Use the OEM‑specified viscosity and follow appropriate service intervals.

How should AMSOIL lubricants be stored?

Motor oils: store sealed up to five years. Greases: use within two years. Store between roughly 32°F and 85°F (0–29°C) in clean, dry, original containers.

What happens if the wrong viscosity oil is used?

Using a viscosity not specified by the manufacturer may affect warranty coverage and can compromise protection. Always choose the recommended grade and verify with the AMSOIL Product Guide.
