Golden Spectro is a modern synthetic blend that surpasses the lubrication and protection ability of petroleum oils. Formulated with clean-burning synthetics, Golden Spectro will not foul spark plugs. High film strength components ensure complete protection against piston seizure and scuffing due to inadequate lubrication. In addition, special additives protect against rust and corrosion. Because it is clean burning, Golden Spectro leaves your engine free of harmful deposits and offers essentially smoke-free operation when used at the recommended ratios.
