Spectro Golden Motor Guard Semi Synthetic 20W50
This is the thick stuff. 20W-50 for the big-bore brutes, air-cooled beasts, and vintage rides that run hot, heavy, and hard. Spectro’s Golden Motor Guard blend gives you semi-synthetic protection with that old-school muscle—it clings like a stage-five clinger and shields like a knight in golden armor.
Perfect for Harleys, cruisers, and anything that shakes, rattles, and rolls with attitude.
One quart of “bring it on.”
Your engine’s not delicate. Neither is this oil.
