1. Conventional Oil: During the break-in period, you can use conventional oil with a viscosity of 10W-30 or 10W-40. These oils are formulated to provide adequate protection for new engines and allow for proper oil flow during the initial running hours.
2. Synthetic Blend Oil: Synthetic blend oils offer a combination of conventional and synthetic base oils. They provide better thermal stability and flow characteristics compared to conventional oils. A synthetic blend oil with a viscosity of 10W-30 or 10W-40 can be a good option during break-in.
3. Full Synthetic Oil: Full synthetic oils are formulated with high-quality synthetic base oils and advanced additives. They offer superior lubrication and protection, including improved resistance to oxidation, thermal breakdown, and wear. While full synthetic oils can be more expensive, they can be a good choice for break-in if you want maximum engine protection.
4. Break-In Additives: Some enthusiasts choose to add specific break-in oil additives to conventional or synthetic oils. These additives are designed to help seat piston rings, reduce wear, and improve overall engine performance during the break-in period.
It's important to follow the oil recommendations provided by the engine manufacturer or builder. They will specify the appropriate oil type, viscosity, and change intervals based on the specific engine design and operating conditions.
Note: During the break-in period, it's also recommended to keep an eye on the oil level and monitor for any unusual signs or symptoms. Regular oil changes are crucial to ensure the removal of metal shavings and other debris generated during the engine's initial operation.
