Question:
Will High-Mileage Oil Cause Problems in Low-Mileage Engines?
Will the high mileage oil harm an engine that has low miles?
-- Dan Mooney, Gillette, WY
Answer:
No.  Mobil 1™ High Mileage, an advanced full synthetic motor oil, is designed to help maximize engine performance and extend the engine life of vehicles with more than 75,000 miles.  Specifically, it contains extra anti-wear additives for added protection, and seal conditioner to help prevent leaks and reduce oil consumption.  Typically, low mileage engines do not need these extra performance reserves.  We recommend you review your owner’s manual to be sure the Mobil 1 synthetic motor oil you select matches the Industry specifications required by your automobile manufacturer
