RevTech Pure is the most advanced motor lubricant available for Harley-Davidson motorcycles. It is formulated using the revolutionary Hydrocracking 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 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.
