mounted behind bumpers? in the trunk? under the car?? highly unlikely anyone with a classic car is going to mount a bypass filter there. lets be reasonable here... these analogies of "keep it in the garage if you dont want it to break" or "you will have to pull an engine because it wears out without a bypass filter" are severely flawed & rather misleading... not using a bypass filter is not going to cause any engine to break or wear out in anyones average time of owning it. apparently the fact that modern cars go to 200-300k+ miles regularly with standard filters is overlooked or avoided by some.

classic cars are driven so rarely these days that it would take 30+ years to reach 90k miles for most & even with poor oil change intervals the engine would still run fine after that & not wear out with modern oils. on a daily driver it would take just as long to reach 200k+ miles, who keeps their daily driver cars for 20-30 years? most people change the oil a lot sooner than needed & by design oil keeps debris in suspension that never see any real metal to metal contact, these ultra fine particles mentioned that will allegedly make an engine wear out never really touch anything to cause any measurable wear. has anyone here ever compared an engine with a bypass to one without & saw excessive wear from the normal filter within an average lifetime of the engine/car? if so please post the results. again, over the road & fleet vehicles will see a benefit with 500k-1 million+ miles, the average daily or classic car, not so much.

& you cant say youre not going to belabor the point of bypass filters when you write multiple long paragraphs about it... this thread wasnt about bypass filters at all, but they sure do get brung up an awfully lot when not asked about... my post was just stating facts about the reality of them compared to standard filters in the average car.

bottom line is use one if you want, but the fact is hardly anyone will bother with them when they dont have much of a measurable benefit to the average or classic car & its been proven for decades that millions & millions of engines do just fine without them.
