Frequently Asked Questions

Is this oil approved for Harley-Davidson?

Yes — Spectro Premium Heavy Duty exceeds OEM Harley-Davidson warranty requirements and is formulated for V-twin engines.

What viscosity is this oil?

20W50 — a heavier-duty weight suitable for air-cooled and naturally aspirated V-twin engines in most conditions.

Why buy a 55-gallon drum instead of quarts?

A 55-gallon drum is cost-effective for shops, multi-bike owners, or frequent oil-change riders. For single-bike use, Spectro also sells quart bottles.

Does this prevent valve sticking?

Yes — the anti-carbon additives are formulated to reduce deposits and valve sticking issues in V-twin engines.
