when you have a stock engine, and you are given a full flow oil filter, you have no choice but to regularly change the oil and filter. if i wanted to add a bypass filter, that may be a different story...but for people that have original restored cars, or daily drivers, adding on extra filtration probably isnt gonna happen, so in that case what i said about having a stock motor and a factory oil filter setup is correct...change your oil and filter every 3-4000 miles and you will be fine. (no matter what kind of oil u use) i have heard people say "i just spent $75 on a full synthetic oil change, now i dont have to change oil for 25,000 miles" ow! im not gonna be buying his car used! lol
we use added oil filtration bypass filters at work, and coalescers to remove moisture, and it does extend the life of the oil some, but it still has to be changed at regular intervals. Last edited by zeebo; 07-09-2012 at 06:13 PM. |

Daily drivers are the cars that can benefit the most from bypass filtration, not showcars, people that use synthetics have the most to gain by getting maximum miles from their investment. These are exactly the people that shouldn't be draining out premium oils just because their full flow will never remove the solids and when they become to saturated with dirt that goes through their so called filter they drain oil that has much more life left in it because it's dirty due to poor oil filtration.
The fact that motor oil is reclaimed is exactly the same premise that a bypass filter operates on. Keep the oil free of suspended solids and it will lubricate your engine without problems. The car manufacturers are decades behind OTR trucks in oil filtration technology where downtime is money and the more miles that you can keep the oil in the rig and keep it rolling the less downtime you have and the lower cost per mile makes your profit margin better. Many truck fleets use bypass filtration to extend the life of the equipment and the oil. I'm guessing that everyone thinks it's big money to install a bypass filter system, most Frantz systems are a little over $200, cheap when you compare the benefits gained as well as it can be removed and transferred to the next car you purchase. Frantz filters have been around since the 50s and 60s and there are still some operating for over 50 years. Chances are it will outlive the owners. |

If a regular oil change regemine safely delivers well over 300,000 miles, the rest of the car is going to be pretty used up by the time an engine is ready for an overhaul. Especially anything in the rust belt.
So (IMHO) the only performance advantage of installing one of these bypass filter systems, is saving resources (oil), and labor if you are a 'change my own oil' guy. Why try to make your engine last a million miles if the vehicle is going to be falling apart before it ever sees 500K? Note: I realize certain well built vehicles are an exception to this reasoning. And I do understand the economic advantage, when used for an extended time. |

Only difference is the wear at 100,000 will be less with a bypass filter than with the regular oil changes with a full flow filter because the small particulate is not continuing to circulate. As the mileage increases the difference in wear and engine health will also be differentiated further. At 200,000 it will be more of a difference than at 100,000 and so on. Less wear also means better dependability over the long haul. Saving 7 oil changes with synthetic oil will pay for the system in most vehicles for DIYs, if you pay to have someone else change your oil it will be sooner yet. Diesels will payoff even sooner because of the larger crankcase capacity.
The more time I can spend driving my vehicles instead of laying under them is a bonus to me. Just like you can never have too much money, your oil can never be too clean. The element is also a tattle tale type so when you change elements the element is exposed so a casual look will spot anything unusual that is circulating through the oil possibly heading off bigger problems. No cutting open a tin can to look at the filter element.

I run the oil in my truck 10,000 miles between changes. I've had it checked by Blackstone twice and both times they tell me it could have gone further (they suggested 2000 miles both times) before the additive package quit working.
I can see very few situations where a guy's daily driver would need an oil change at 3000 miles.

On my 2011 F150, I plan on 5000 miles on oil changes, using a full synthetic.

Unless your driving it in a strip pit, pulling a trailer, you'll be throwing a lot of oil life away.

I bought my Honda Accord new in 2001 and have changed the oil and filter (non-bypass) every 7,500 miles. It just hit 220,000 miles, it still runs great and it doesn't consume any oil.

1). Seeing how the by-pass filter is mounted using the small sending unit hole for a supply line, how does it keep up with the volume of oil passing through the motor? 2). Frantz says to change the TP cartridges every 3000 miles, but what about the conventional oil filter. 3). How do you test your oil to see if the additive package hasn't broken down? Thanks, Gary |

1) It doesn't the internal engine oiling is still handled by the full flow filter and each filter is independent of the other, it is a closed loop that cycles oil back to the pan. It only cleans it and sends it back to the pan. It has no part of the internal engine oiling whatsoever. Its rate is about 1 quart a minute roughly. 2) Since the bypass filter is doing the bulk of the work the full flow should take forever to get dirty, and if it would happen by some odd fluke plug, the bypass in the engine or the filter would just open same as it does now, because that is the way the engineers designed it, priority is oil to the moving parts filtered or not. The bypass is open more than you think it is in an engine and oil is going through the engine without being filtered. If it makes you feel better change it when you do change your oil, I leave mine on as the job it is doing is plugging the holes in the oiling system. I have doubts it's really catching much dirt at all with the oil being kept clean by the bypass filter. So the answer would be barring any lab analysis 10,000-12,000 miles, myself I'm not worried about changing it. 3) Since the bypass filter is removed at 3-4000 miles you need to makeup a quart of oil at that time, so the additives are freshened. With little work to do the additive package holds up much better than with oil that is only partially filtered. There is only one surefire way to have that tracked and that's by sampling it and having it analyzed by a lab. I have researched it plenty as far as lab results with Frantz filters and I have faith that using a premium oil the additive package will be fine for the length of time I'm using the oil. I hope I've answered your concerns, more questions I'll be happy to answer them. Brad Yost |
