I traded PM's with Bob Jusnes on here asking him about the benefits of a bypass filter. He said there might be one or 2 members on here with one.

For those of you who do have one? have you seen the cost benefit in yours? how is the condition of your oil? etc... questions like those that i have. Any info you have, i'd appreciate it. -Mike-

 

what the heck is a bypass oil filter?

 

a bypass filter is a specialized filter that is used to keep oil clean all the time. Different brands of bypass's use different media to filter the oil. Alot if not all bypass filters can filter oil down to 1 micron and further smaller. They remove any signs of fuel, dirt or any other contamination in the oil to keep it clean all the time.

Most semi big rigs have these to help reduce costs in oil changes and aid in clean lubrication at all times. A bypass filter can help keep the oil so clean that basically you don't need to change the oil, just the element every 3000 miles or so and top off with your choice of oil. I never ran a bypass filter because i feel that i don't drive enough miles to take advantage of the benefits a bypass filter can offer. I suppose if i was an extreme perfectionist about my engines lubrication, i would run one. I'm just stating what i have learned about them. -Mike-

 

i thought the lubrisity of oil breaks down over time which causes a loss of lube when compared to new oil? the filter just takes out some of the junk, but i thought used oil loses its special doohickeys to make it better, not just cause its 'dirty' and, oil in a broken in engine shouldnt really be 'dirty' cause nothing should be getting past the piston rings, if it is, you got major problems. thats my thought on this.

 

Oil loses its vescosity after 3000 miles(unless we are talking about synthetic) and no filter can help regain an oil's vescosity. IMO, change your oil and filter every 3k and dont worry about claims from manufacturers that "improve" or "extend" the life of your oil. Oil isnt cheap anymore, but its cheaper to change the oil and filter at 3K than it is to ruin an engine with "experimental" bs...

 

I run the amsoil bmk-13 duel remote by-pass set up. I use the eao-15 full flow filter and the eabp-90 by-pass filter along with there 0W30 oil. I can do nothing but praise this system, it works as they claim. I was using oil anaylisis and changing the full flow filter at 10,000 miles and changing the by-pass every 20,000 miles. My samples always came back clean. With there new ea series filters the full flow is supposed to be good for 25,000 miles and the by-pass for 60,000 miles. I don't have enough miles on the new filters to compare, but it is looking very promising.
