AMSOIL Service Life
Interval Chart

1. UMR means use equipment manufacturer's recommended drain interval. N/A means the oil may not be used in the application.

2. Where AMSOIL recommends up to 2, 3, or 4 times longer, it means up to 2, 3, or 4 times the equipment manufcturer's recommendation. Change the lubricant at the time or distance interval indicated, whichever comes first.

3. Oils specifically designed for an application are shown in the green shaded boxes.

4. Blocks not shaded green indicate oils that are not specifically formulated for these applications and are therefore the oil of second choice. Their performance in the application would still be superior to a similar viscosity conventional oil.

5. Oils shown in boxes marked "N/A" should not be considered due to viscosity or performance requirements.

6. All drain intervals can be extended (with oil analysis) indefinitely by using AMSOIL By-Pass Oil Filtration and AMSOIL Oil-Wetted Foam Air Filter.

7. All AMSOIL lubricants are warranted by AMSOIL INC. (see AMSOIL Product Warranty).

8. Oil Analyzers, Inc. offers oil analysis services for all engine and component applications. See Oil Analysis Page for price list and more information. For non-commercial passenger car oil analysis, the Trigard Protection Plan is also available.

9. AMSOIL SDF Oil Filters must be changed at least every 6 months regardless of miles driven. Replace other brands of oil filters at the engine manufacturer's recommended filter change interval.
