    Well, we have really just ignored it for a long time. That has had the unfortuante effect of making some believe what they hear is true. So what are they doing about it? They are having myslef and the other technical trainers in my group answer filter, spark plug and coolant questions on various internet forums with engineering facts, no marketing bs, just facts. I hope you buy my compnaies products but I am only here to educate, not sell.:D

    Sounds like you engine is pretty sound mechanically. There is no telfon in any of our filters. There was a time when PTFE was in vouge with oil and engines (Slick 50). It later proved to be of no real benefit so most poeple making PTFE containing products have discontinued them. Your oil pressure is fine, you should have above 14psi idling in gear and then around 10 more psi for each 1000 rpm. For example, at least 40 psi @4000rpm.

    Thanks for the info. I remember the Slick 50 era-heck I used it.It was pre-internet.

    Yes, it is a good idea to have Fram folks countering those rumors. Whenever Fram comes up-all forums- there is plenty of negative info attached to it. I still use a primitive type of fram filter in my old1 SR500- a single cylinder Yamaha 500.

    Yes, my 5.7 must have been well taken care of.I got it at 194,000 miles-211,000 now.It gets an honest 21 mpg on long 3000 mile(New Orleans-Flagstaff) highway trips with the CC set at 68 mph(actual average driving speed is probably more like 63 mph-road work). This is actually measured mpg, not NAV mpg. I have no idea how GM manages that with a vehicle like that. Guess they had lots of time to perfect the SBC. It isn't really geared very tall-1725 rpms AT 60 MPH-maybe 43 psi in the tires.No other hypermiling tricks other than driving at a reasonable speed, and gliding up hills, overpasses.

    Thanks

    motorking,

    Great to have you aboard! I agree that it would be better to talk facts and data rather than "I thought I heard once that...". I know there's gobs of ways to talk about what makes one filter better than another. I've seen you mention a few numbers, but know that there's a lot more information you haven't given us yet. Are these available? Will they be? Specifically, I know filters can be evaluated by:

    efficiency vs. partcicle size plot over a wide range of particle sizes
    restriction at a given flow
    restriction change with temperature
    how restriction changes over the life of the filter (as it fills up)
    pressure to collapse or burst the filter
    Bypass pressure
    Durability validation
    process/quality control
    How all of the above compare to competitive filters

    I think the trouble for us consumers is that the only folks with enough resources to do a really scientific comparision of competitive filters are those that want to sell us one of them! If they let the test results be seen, we've gotta wonder "hmmm.. I wonder if they're just showing us the results of the tests that made their product look good."

    you are right about that. Independent testing costs a fortune and even then, any manufacturer could pick out the pieces that are favorable to themselves. We are in discussion here trying to figure out how we could present this info in a unbiased manner.
    BTW- even though I am a big high Performance guy, i have squeezed a combined city/hwy 25mpg out of my 400hp Cadillac CTS-V using hypermiling driving techniques. to me that is really a feat of engineering, a car that does 13 sec qtr miles and can 180mph delivering that kind of economy. SWEET!
