Quicksilver OptiMax DFI 2-Stroke Marine Oil – 1 Gallon

Quicksilver OptiMax DFI 2-Stroke Marine Oil – 1 Gallon – 8M0229799

Quicksilver OptiMax DFI 2-Stroke Marine Oil (Part #8M0229799) is a high-performance marine engine oil specifically formulated for Mercury OptiMax, Mariner OptiMax, and compatible direct fuel-injected (DFI) 2-stroke outboard engines.

Designed for the demanding lubrication requirements of direct-injection marine engines, Quicksilver OptiMax DFI Oil provides enhanced wear protection, corrosion resistance, and reduced carbon buildup to help maintain reliable engine performance.

Its advanced formula contains synthetic additives that improve lubricity and resistance to scuffing, helping protect internal engine components operating at higher temperatures and reduced oiling rates.

Available in a 1-gallon (128 fl oz) container, this oil is ideal for maintaining compatible Mercury and Mariner OptiMax outboards and other DFI marine engines requiring OptiMax DFI oil.

Quicksilver Part #8M0229799 supersedes older part numbers 92-858037Q01 and 858037Q01.
