How Can I Protect My Rebuilt Engine? is a question we are regularly asked. Engine building needs to be done correctly with the right parts and the right lubricants to ensure all components are properly protected. It can end disastrously if there’s not enough lubrication when the engine is first started, or if the engine oil that is used during the running-in process fails to deliver the right protection.
Things can, and do, go wrong during the initial start-up as the freshly re-built engine, has to build oil pressure quickly so that all of the critical wear surfaces receive lubrication.
Where a camshaft and/or the lobes are being re-built, we recommend our Competition Assembly Lubricant along side one of our Running-In oils. If the re-built engine does not have a re-built camshaft, then you can safely use a running-in oil without the need for an assembly lube.
Millers Oils produce several products to help during the engine re-build:
As with all our products, the optimum amounts of ZDDP additives are used to provide maximum protection to your rebuilt engine – see our Classic Product Info page for more details.
