Frequently Asked Questions (FAQs)
1. Does high mileage oil really work?
Yes, high mileage oil is designed to work effectively in vehicles with higher mileage. It contains seal conditioners that help restore worn engine parts and prevent further wear and tear. These seal conditioners also reduce oil seepage from the engine, ensuring better performance and protection.
2. What kind of oil is used for a high mileage oil change?
For a high mileage oil change, it is recommended to use high-mileage oil. This type of oil is usually a blend of semi-synthetic oils, which offers the best combination of qualities and the right density balance. High mileage oil is specifically formulated to meet the needs of engines with over 75,000 miles on them.
3. Is high mileage oil better than synthetic?
While full synthetic oil is generally considered better, high mileage oil is a suitable choice for vehicles with over 75,000 miles. The decision between the two depends on factors like cost and the age of the vehicle. If your vehicle has high mileage and you want to address specific issues related to aging engine parts, high mileage oil can be a good option.
4. What kind of oil should I use for 150000 miles?
For vehicles with 150,000 miles or more, it is recommended to switch to high mileage motor oils. There are specific high mileage motor oils available, such as Valvoline's High Mileage 150k+, which is specially formulated for engines with over 150,000 miles. These oils provide the necessary protection and benefits for older engines.
5. Should I use thicker oil in a high mileage engine?
In some cases, using a thicker oil can help improve oil pressure in older, high mileage engines. Thicker oils have a heavier base weight, which can provide better protection for worn engine bearings. However, it is important to consider the manufacturer's recommendations and consult with a professional to determine the most suitable oil viscosity for your specific engine.
6. What is the disadvantage of high mileage oil?
One potential disadvantage of high mileage oil is that some thicker oils, like 10W-30 full synthetic and 5W-20 full synthetic, can make it harder to start the vehicle, especially in colder temperatures.
