secondary oil filter isx15

[Rockhwy]

It is called a bypass filtration system there are different systems you can buy, but what it does is it takes oil and runs it through a filter that can filter smaller particles than the filter on the engine, this is recommended to get more soot out of your oil to make it last longer just for reference amsoil oil makes a oil bypass system. Oil bypass systems have been around for a long time 40 years ago when I started trucking almost all trucks had a bypass system if you ever have seen old trucks or old truck movies especially a conventional it was a big canister you might see on side of cowl or battery box with lines going to it those had replaceable elements some are like that some have spin on filters
