Rislone Engine Treatment gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages.

• Restores lost compression, power, and efficiency.
• Penetrates better than conventional motor oils.
• Reduces friction and wear, especially at start-up time... improves cold cranking ability.
• Removes engine-damaging sludge, varnish and gums.
• Maintains normal oil viscosity at engine operating temperatures.
