Running in oil — also known as break in oil — is an essential fluid for anyone looking to ensure long-term engine performance from a new or rebuilt engine. Unlike standard engine oil, running in oil contains fewer additives, allowing controlled wear during the bedding-in phase. This leads to improved compression and oil control down the line.
If you’re looking for unbeatable quality, Millers running in oil is the choice for you. This leading oil manufacturer is one of the most trusted names in the field, with break in oil designed to offer excellent protection during initial start-up without hampering the mechanical process of running in. We also stock options from another leading motor brand, Motul.
Need advice on how long to run your engine on break-in oil or when to switch to regular engine oil? Our expert team is happy to help. They can also help you make the right choice on any other oil you need, including gearbox oil, additives, brake fluid, and power steering fluid.
