Frequently Asked Questions

Is this oil certified for Harley warranty coverage?

Yes — this lubricant meets API-SH/CG-4 service specs and is warranty compliant for qualifying Harley engines.

Can I use this in my Evolution or Twin Cam Harley?

This oil is custom formulated for pre-Evolution engines. Check your owner's manual or contact Klotz for the correct viscosity and formulation for your model year.

What does '50w straight weight' mean?

50w is the winter/cold-start viscosity grade. Straight weight means a single viscosity (not multi-grade), providing consistent film strength at high temperatures.

This 1-quart bottle is one unit of capacity. Check your owner's manual for your engine's total oil capacity — pre-Evolution V-twins typically hold 2–3 quarts.
