Opti-4 SAE 5W30 is a premium four-cycle engine lubricant formulated for reliable cold-weather performance and year-round protection. This 20-ounce bottle uses Opti’s patented eutec tic additive technology, which restructures internal metal surfaces to reduce friction, wear, and heat while improving engine run-in. The formula supports easier cold starts, lower operating temperatures, reduced oil consumption, and long-term corrosion protection during storage. It is suitable for small four-cycle power equipment that specifies 5W-30 oil and qualifies for Opti-4’s extended engine warranty program when registered. Show more
