    Weeping FRAM Ultra XG2

    Probably the base seam crimp if nothing obvious was seen with the gasket or gasket sealing surfaces. Lots of WIX filters have had leaky seam crimps reported, but it can happen to any filter. Contact Fram ... they will probably send you a free replacement or two.

    Weeping FRAM Ultra XG2

    Pull the gasket out of the base groove and look on that sealing side (both the gasket and gasket groove surface) to see if anything looks strange. If not, then it's possible it was leaking through the crimp seam.

    What are safe oil temperatures during spirited driving?

    I would like to hear from someone here who tracks their car that has an accurate digital oil temperature readout, to say what is the oil temperature difference seen between two different oil viscosities (like 5W-20 vs 5W-30 in same brand/additives) ran on the same track in the same weather...

    What are safe oil temperatures during spirited driving?

    MolaKule said: "A thinner oil, while having a slightly lower heat capacity, actually transfers heat quicker because it moves faster." But when oil volume in an ICE is being pushed through the oiling system by a PD oil pump, the flow rate (and velocity) through the force fed circuits and parts...

    What are safe oil temperatures during spirited driving?

    What are you basing the bolded statement on? The word "dissipate" implies that thinner oil will transfer more heat (at a faster heat transfer rate). Not sure anyone can actually prove that except in a very controlled laboratory setting like some of the papers I linked earlier show. Even...

    What are safe oil temperatures during spirited driving?

    The "It" I'm talking about refers to the subject of "thinner oil cool better". Specifically in the application of heat exhangers (oil coolers) since Post #9 specifically brought that up, and that's the main focus I was discussing. But there's also the heat generation aspect of oil due to...

    What are safe oil temperatures during spirited driving?

    Forgot to add, that a less viscous oil (with all other things being equal) will run a bit cooler because it doesn't create as much heat from shearing. So it's possible for oil temperatures to run a bit cooler because of that factor. But that's not the same thing as saying "thinner oils cool...

    What are safe oil temperatures during spirited driving?

    You're "data point" is basically hearsay - regardless who it came from. Did your buddy actually put instrumentation on the inlet and outlet tubes of an oil cooler to see how different oil viscosity effected the in and out temperatures. And did he measure various oil temperature locations...

    Ford F-250 "TRD" Edition

    Maybe he put a Toyota engine in the F-250 to make it more reliable ... 😄 ;)

    CAFE Standards in the US and Oil Weights

    Qualifying engines are sacrificial. As long as it makes it a few qualifying laps it's done it's job.

    Aem dryflow air filter

    In order for the turbo or SC to create boost it will need to increase the air flow through the air filter - what goes into the engine must come in and go through the filter. So I'd say boost does equate to a higher airflow rate through the air filter. Why else would one collapse otherwise when...

    What are safe oil temperatures during spirited driving?

    Your turn ... show me the study or any technical information that supports your claim that "thinner oils cool better". If the info is out there I'd actually like to see it. All you have is some comment based on what you "heard" 10~15 years ago. Lots of people make claims and never back it up...

    What are safe oil temperatures during spirited driving?

    Back to this: Of course the coolant heats up much more quickly than the oil ... that's pretty much true on any vehicle. The heating source for the coolant is mainly from the combustion in the cylinders, whereas for the oil heat of combustion is the minor heating source. So you are comparing...

    What are safe oil temperatures during spirited driving?

    There are other properties of a fluid involved in heat transfer than just the "thickness" of the liquid. You just can't say that "20 weight cools more efficiently and rapidly" than 30 or 40 weight without showing a source where that was actually proven by controlled experimentation. You're...

    How old is my Purolator?

    Is there any other numbers on the can that look similar to that date code - like on top of the can? Not sure if Purolator used letter "Q" because it looks similar to zero. Maybe they did back then, and if so then it's around 2004-2005 time frame.

    Flow rate into parts

    Broad based ... yeah, that's it. What about that "whole different animal" that's not controlled by the PD pump?
