- 10W-40: This is a commonly recommended weight for high-mileage engines and is suitable for most climates. It provides good protection and can help reduce oil consumption.
- 5W-40: This is a slightly thinner oil that may be suitable for colder climates or if the engine experiences excessive oil consumption. It provides good protection but may not be as effective in reducing oil consumption as 10W-40.
Here are some additional tips for maintaining a high-mileage engine:
1. Stick to the recommended oil change intervals.
2. Use a high-quality oil filter that is specifically designed for your engine.
3. Check the oil level regularly and add oil as needed to maintain the proper level.
4. Keep an eye for any signs that indicate excessive oil consumption, such as low oil pressure or a visible increase in the amount of smoke coming out of the exhaust.
5. Avoid overheating the engine and make sure the cooling system is functioning properly.
6. Use the correct fuel and avoid using low-quality fuel.
