H-D Techie Talks: Engine Oil Filter Replacement Benefits


All of the good stuff caused by that simple replacement to some high flow air filtration system on a Harley are very well known. An improved breathing motor is really a crispier, happier V-twin. It’ll produce much more horse power, much more torque, as well as turn in better miles per gallon. Well, talking about all of this with master tuners that worked tirelessly on a large number of bikes every year. Air filtration system has definitely demonstrated their value, but is it similar with an oil filter?

If you have made the switch to synthetic lube, that change to synthetics delivers pros all its own. Most likely, synthetics do a better job of lubricating a motor, they will preserve their viscosity for a longer period, flow significantly better making the duty of the oil pump much easier, and they’re just considerably much better at cooling down a motor, something important for just about any air-cooled motor unit. Full-synthetics can decrease engine temps from 15 to 25 degrees.

There are plenty of brands of filters out there meant to handle synthetics, though, just like the high quality ones from Drag Specialties and, particularly, the K&N Wrench-Off designs. These kind of filters have been especially engineered to be compatible with those highly-concentrated exotic synthetic lubricants; the filtering media inside will not breakdown, and they make room for the larger flow rates related to synthetics. They are simply significantly better filters by and large. The K&N units additionally load up in 25 % much more filter area.

Yet another great substitute is to grab some of those multiple-use metal-mesh oil filters have become popular for a lot of drivers. Not only would this function as the final lube filter you’ll ever buy through these cleanable and reusable oil filters run more enhanced versus the high quality disposables and the filtering component inside these things is produced with medical-grade 304 stainless steel filtration fabric. Just one square-inch of it will circulate more or less 2 gallons of lube a minute at only 1 PSI pump pressure.

Some even incorporate rare-earth magnets in the base to further trap metallic contaminants and debris before it even goes to that extra-fine filtering mesh. In addition to all that the aluminum containers these filters use, they feature lots of cooling fins that assist decrease lube temperatures a whole lot more. The filtration system turns into, in effect, a mixture of oil filter/oil cooler. There is a sophisticated bypass system built for consistent operation and correct differential pressures and a twist-lock structure ensures positive component positioning inside the container while enabling straightforward disassembly, check up, and clean-up.

And here is the kicker, apart from carrying out a superior job of cleaning and cooling the essential oil, 3rd party testers performing side by side comparisons to these reusable engine oil filters and an ordinary non reusable charted approximately an 8-horsepower increase as well as 10 additional lb-ft of torque. These reusable engine oil filters have already been authorized by the FAA as well. If they are sufficiently good on an aircraft, where you can not exactly pull over to the side of the road if a specific thing goes completely wrong, they can be more than prepared for a H-D.

Getting back to that original question: Will there be performance gains found in something as simple as an oil-filter exchange? The answer is yes, absolutely. And those reusable kinds along with their aluminum finned canisters turn out great also.
