Sierra Blue Premium TC-W3 2-Stroke Outboard Oil – 1 Gallon | Part #95003
Sierra’s Blue Premium is a high-performance TC-W3 rated 2-stroke oil formulated for carbureted outboard engines that mix oil with fuel — either through oil injection or pre-mix. It exceeds the TC-W3 standard across all major certification bodies and is designed to burn cleanly, protect against wear, and reduce aquatic impact compared to conventional 2-stroke oils. The gallon jug is the practical size for boaters who go through oil regularly or want to keep a full season’s supply on hand.

- Optimum burnability — formulated for clean, low-smoke combustion
- Maximum lubrication and detergency — keeps engine internals clean and running smoothly
- Reduced aquatic toxicity — lower environmental impact compared to many conventional 2-stroke outboard oils
- Will not void manufacturers’ warranties — suitable for all outboard engines specifying TC-W3 oil

Parts Desk Insights
Best use case: The gallon format is the right choice for boaters running oil-injected outboards who go through a full gallon or more per season, or for those who pre-mix fuel for smaller carbureted 2-strokes and want to buy in a size that lasts. It’s a cost-effective everyday TC-W3 oil for recreational outboard use — reliable protection without the premium of a full synthetic. For smaller quantities, the Sierra Blue Premium TC-W3 2-Stroke Oil, Qt. – 1895002 and the Sierra Blue Premium TC-W3 2-Stroke Oil, Pt. – 1895001 are available. If your engine or operating conditions call for a full synthetic TC-W3 oil, see the Sierra Fully Synthetic TC-W3 2-Stroke Outboard Oil, Gal. – 95403 or the Sierra Fully Synthetic TC-W3, Qt. – 95402.
Compatibility note: TC-W3 oil is for water-cooled 2-stroke outboard engines only. It is not suitable for air-cooled 2-stroke engines or 4-stroke engines. Always confirm your engine’s oil specification before use. This product is sold in case packs — confirm case quantity at time of order.
