Quote from Blackstone-Labs FAQ page: http://www.blackstone-labs.com/faq.html "What can I do to my engine to reduce wear? We recommend cutting back on excessive idling and short trips, as these driving conditions are harder on an engine. We have also seen very good results from pre-oilers, which are add-on electrical oil pumps that come on when the ignition does to build oil pressure before the engine starts. Much of the wear in your oil is caused at the start-up. Engines using a pre-oiler tend to run very low wear metals and can usually run the oil for longer use intervals." The importance of pre- lubricating new, broken-in, or rebuilt engines cannot be over emphasized. Many of these engines are badly damaged within the first few minutes of operation because of lack of lubrication to vital parts. In every day use, at start up, most of the parts such as pistons, rings, cylinder walls and bearings must have immediate lubrication to prevent scuffing, scoring and bearing damage. In some cases it can take as long as one to five minutes of engine operation for the oil pump to prime itself, fill the oil passages and oil filter, then deliver oil to the various parts of the engine. These unnecessary failures can be prevented by pre-lubricating the parts and forcing oil under pressure to the oil galleries, oil filter and oil pump. This provides immediate lubrication to all pressure lubricated parts and eliminates the time-lag that occurs in the oil pump priming itself and filling the oil galleries when the engine is first started. The oil pump for some engines is not self priming and when the oil pump cover has been removed for any reason, the pump gear cavity must be filled with oil. Normal engine oil pressure, or about 20-30 psi, should be forced to the galleries. The oil supply line from the pre-luber can be attached to the engine at any convenient tapped hole on the outside of the engine block that leads to the oil pressure circulating system in the engine. Hook-up points are located differently, according to the engine. ENGINEGEAR IS LOOKING FOR A COMPANY TO MANUFACTURE AND MARKET THE UNIT. Please contact us if interested.
