Spectro 4 is a blend of highly refined, paraffin base oils with the very latest A.P.I. SH technology additive package fortified with additional anti-wear additives to provide smooth shifting characteristics in motorcycles with transmissions that share the engine lubricant.
Spectro 4 uses a shear-stable olefin co-polymer viscosity index improver to resist viscosity breakdown in a motorcycle/ATV gearbox environment.

Applications
Spectro 4 is the ideal choice for all four-stroke ATV's and motorcycles where an economical, high performance oil is desired for touring, competition, and off-road use. Spectro 4 can be used in any four-stroke gasoline engine, but is manufactured specifically to meet the unique demands of motorcycle engines. Observe manufacturers' recommendations for viscosity and change intervals. Recommended for use wherever an A.P.I., SF, SG, SH oil is specified.
