1976 Harley-Davidson Oil Recommendations
The 1976 Harley-Davidson lineup is built around the Shovelhead V-Twin (and earlier Panhead and Knucklehead Big Twins on the oldest pages), engines that pre-date the synthetic oil era entirely. AMSOIL 20W-50 100% Synthetic V-Twin Motorcycle Oil is fully compatible with these vintage motors and gives them the heat resistance, shear stability, and oxidation control they could never get from the petroleum oils they were designed around. Sportster (KH, XL, XLH, XLCH) models from this era are listed below alongside the Big Twins.
Synthetic 20W-50 V-Twin oil also handles the wide oil-temperature swings vintage engines see between cold-weather rides, slow-speed shows, and long highway pulls. The oil's broad viscosity index and resistance to deposit buildup keep these older Big Twins running cleaner than they did when new. Pick a model below for engine capacity, oil change interval, and the AMSOIL part numbers for engine oil, primary fluid, transmission fluid, and oil filter.
