RevTech® Pure™ Advanced Motor Oil / RevTech Pure™ is the most advanced motor lubricant available for Harley-Davidson® motorcycles. It is formulated using the revolutionary Hydro-cracking refining process which creates greater hydrocarbon consistency and further removes contaminants. The resulting base oil is so pure, it is clear. This ultra-pure base oil provides synthetic-like performance from a petroleum oil. Hydro-cracked oils extend engine life by generating 90% less corrosive acids than conventional motor oils. They also maintain lubrication integrity by reducing sludge formation by more than 50%, and resisting oxidation (thermal degradation) up to three times longer. Using this base oil and our proven RevTech® additive package, our engineers have formulated RevTech Pure™ to withstand the unique demands of air cooled V-Twin engines, whether new or old. RevTech Pure™ meets all warranty performance criteria for Harley-Davidson® engines and its use does not void new vehicle warranties. Sold in convenient resealable one quart plastic bottles. Owners of Harley-Davidson® motorcycles demand the best, and RevTech Pure™ delivers. Meets API CI-4/SL service levels.
