If there is a spot where oil could leak out in your engine, then synthetic oil is more likely to leak than conventional.
Do high mileage engines need thicker oil?
A: Yes. This is a practical method to improve oil pressure in an older, high-mileage engine. The slightly thicker oil film from the heavier base weight oil — 10W — can help protect worn engine bearings as well.
Can you go 10000 miles with synthetic oil?
Full synthetic oils will actually last well beyond 10,000 miles.

Is Synthetic Oil Better?
Synthetic oil is by far better for performance. It protects the engine due to lower levels of friction. Additives help clean the engine of deposits. And, fewer impurities mean it burns cleaner, thickens far more slowly, and has fewer deposits to start.

High mileage oil is designed for vehicles with more than 75,000 miles. … This leads to less leakage and oil burn-off, which can be common in older cars. If your vehicle is high-mileage and high performance, it’s suggested that you go with this type of synthetic oil. Not every car requires synthetic or high mileage oil.
Will switching to synthetic oil cause lifter noise?
Registered.
