Debating: Do the oil bypass or spend it elsewhere?

In a few weeks, a fellow forum member is going to show me the ropes on doing an EGR delete, exhaust and plus a few other misc updates and mods. I was going to do the oil bypass while I was doing the coolant filter too. But the guys over at bob is the oil guy ( I KNOW its not Bible, but they are pretty accurate most of the time ) are telling me that the bypass filter isn't going to do much if you do 5k OCIs. It would be money wasted. But on here guys tout that the by pass filters the oil even further and gives our injectors the best chance at a damage free life.

Should I spend the 300 on the NUC bypass, or just go and spend it on something else on the truck?

else where in my opinion. If you were trying to push the OCI longer distances it would be worth looking into, but if your going to change your oil every 5k anyway the stock system is adequate

I think oil and water bypass systems are great investments. That an egr delete seems to be a good start at prolonging life of the motor. I lost one injector early and ford replaced it. The injectors are sensitive to quality clean oil, so ever since I have ran synthetic oil and the FS2500 bypass. Haven't had an injector issue since. Not saying I would of had an issue without the bypass, but I'm happy I have had no other issues. I do not extend intervals of oil. I only change the bypass filter every other oil change.

Clean oil is a must like stated above.....I wouldnt extend my OCI's But Ill tell you what..after deleting my EGR and my Oil Bypass on it at 4K so far my oil looks as if i changed it yesterday....even b4 the egr delete it would stay clean....I sleep good at night knowing my HEUI system runs on clean oil

i have since changed it somewhat...actually might relocate it all to the frame rail but here is my NUC kit

Do the bypass and use a 7500 mi OCI. Used Oil Analysis Reports have shown that to be perfectly save with Rotella T6.

The key to long injector life is good, clean oil. An oil bypass filter is a great investment, but the folks at BITOG are correct. It won't allow you to extend your oil change interval (OCI) significantly enough to earn you a good return on your investment. If anything, it would give you peace of mind concerning the health of your injectors...

Anybody shed any light on something I read at one point.... I'm guessing this was using Amsoil filters and a bypass, but they were stating, 100,000 miles on the same oil with just filter changes. I'll see if I can find it again, but in the mean time....

Would be interested to see those reports. I have an amsoil bypass and have been doing 5K changes with T6. All the 6.0 guys scared me with the oil shear talk after I installed my bypass so i never extended it. I ran the same AMSOIL in my cummins for 20K intervals changing the fileter every 10K and bypass every 20K and had awesome oil analysis result.

I digress, I would love to be able to extend my intervals if 7500 was proven OK on T6 and bypass.

2-3 micron filtration can't minimize oil shear that is a fact

I still run it but do the extreme oil change 5k interval and probably waste a little coin

but I am OK with that LOL but honestly I am sure I could go with the normal interval specially with the bypass

^ i do the same as well....All those trucks that go 20K Plus obv arent HEUI Systems....their engine oil only deals with regular pressures vs 3000psi + on HEUIs. So you lose viscosity and less protection even tho the oil is still clean and fine deposit wise.
