You can't tell enough about an oil filter by cutting one up and measuring it to be able to make any sort of pronouncement as to its actual effectiveness as an oil filter.

Corvette guy has collected a truly impressive amount of data, none of which is more than peripherally related to the effectiveness of an oil filter in actual use. It's pseudo science. The only test of an oil filter is to run "dirty" oil through it, while measuring flow rates, pressure drops, and how much dirt of what particle size is in the "before" and "after" oil. That's the purpose of the SAE tests which he dismisses out of hand.

Buried somewhere inside the narrative where I'm not going to try to find it again is also the admission that he doesn't have the equipment to measure these actual parameters. Without that, this "study" is not worth the digital paper it's not printed on.

The fact that one or more of the oil filter companies have gone after him is not any more a validation that he's onto something than is your answer to the classic question, "Have you stopped beating your wife yet?"

Here are the pictures I promised.

Folks, Im not stating that this filter is an EXACT duplicate, and everyone that has a 2005 Merc 60 BF should use this filter. As chip stated there are many more tests that can be performed to further analyze and compare. The tests I performed were for ME, to satisfy my OWN curiosity. I am just sharing what Ive found, and the results of some testing that Ive done, with the tools I have.

From the results of my tests, and the 100,000+ miles Ive driven on a SuperTECH filter, Im confident in its abilities to adequately filter my outboard motor oil. I am using this filter.

Kmclemore,

Thanks for the information on the Alpine. I think they had Roots engines in them. . . which I know nothing about.

Yes I am familiar with the Griffiths. One of those have been on my Christmas wish list for many years. (along with many other toys) I had an opportunity to actually drive one on a racetrack many years ago.
Like MeMine stated, very fast. With the incredible power to weight ratio, and the short wheelbase, it was very squirley. Hard to keep engine coolant temps down too.

I actually got involved in TVRs in 1982 when I purchased mine. My father-in-law used to race vintage cars. That is how I got introduced to the manufacturer. His collection was unusual, a 1958 AC ACE Bristol, a TVR vixen, a TVR 2500M, 2 Elvas, a Lotus Elan, an E type Jag, and a Jomar. If your not familular with a Jomar, it was the 4th rendition of the TVR. TVR started in 1949 by Trevor Wilkenson and they were as follows: TVR No1, TVR No2, TVR No3, then, the Jomar. They made only 6, 3 of which made it over to this country. Three were hard tops. His was a HT. The unusual thing about the Jomar (named after Trevors children John & Margaret) was the front and rear body. They came out of the same mold. They were powered by Coventry Climax engines. The CC engine was originally used for fire pumps, as they were light enough for 2 firemen to carry.

The Brit sports car I lust after the most is the Daimler Dart SP250. I've never driven or even ridden in one, never seen one up close, haven't seen one in person in probably 30 years. I don't care if they're known to be POS, that car just exudes "cool" and I want one.

Next on my list are the all Jag XK Roadster/DHCs: 150, 120 and E-type in that order. MG-T series (any) A-H 2000-3000, and the aforementioned Sunbeam Tiger to round it out.

Harrison - nice work and nice shots.

I would stick my neck out and say those two filters were made in the same place and were labelled differently to the two distributors imho...

what was the price delta again...like $10???

The Daimler did have a 2.5 V8 (thus the "250," I believe.) It was relatively rare only in that Daimlers themselves are relatively rare. That motor also powered the Daimler version of the Jaguar MK II, which I believe was identical to the MK II except for the insignia and the engine. It's interesting that the Jag XK straight six, DOHC engines were putting out 235HP with twin SUs in the saloon cars, 265HP with triple SUs in the XK150 and early E-Types, while the Daimler V8, conventional pushrod OHV (though with hemi heads) also with the ubiquitous twin SUs were advertized at a relatively anemic 140HP. If you look at pictures, you'll see that the rather large side draft SUs, which work well with straight, narrow engines, don't fit so well between the banks of a V8 and result in a pretty messy, very tall package.

I read on a website that the Daimler V-8 was based on a contemporary Cadillac engine of those days, which would almost certainly mean it would have been a cast iron block; I don't believe Caddy made any aluminum engines in that time frame, though I know Buick did and also believe that was the basis for the Rover V8 and several others. I'm also quite certain Caddy, pretty much legendary for the size of their engines, wouldn't have come within a mile of anything as puny as 2.5 liters, so, unless they debored and destroked the Caddy to about half size, the Caddy rumor is probably bogus.

Well, funny you should say that, Chip, because I used to own a Dart. The engine is indeed all alloy (apart from the moving bits), but it's not based on the Caddy engine - it is an entirely unique engine - indeed, it's a 'Hemi'! The car also had 4-wheel disc brakes - I think it was the first production car offered that way. The body is fiberglass and the frame is basically a tube-job, but it's pretty strong. There were three variants and they are virtually indestinguishable from one another, but the improvements were that later models had stronger frames and bodies, mostly. Mine was a type III, the last and best of them. Electric overdrive was an option and mine had that - made highway crusiing really nice.

Interestingly, the British police used to use them as chase vehicles on the (then new) Motorways... quick as heck they were! Sort of like an English Corvette!

Ill buy into the first few miles of running a car are hard on the surfaces, but I doubt it is documented that the first few seconds of startup, where the bypass issue is relevant, causes "most engine wear"

Please correct me with a source or study of course.

I guess I'll have to back off on the "well documented" part of my statement. I've spent several hours researching this and have found a bazillion articles that make the same statement. Oil additive merchants, Oil companies and gadget peddlers aside, even the EPA and American Lung Society, make the same statement. I have even found it in several major university research papers. But, none of them, zero, zippo, nadda, gave refference to a study on the matter. It appears that this is one of those well known "facts", that is so well known, that no one knows where the "fact" came from.

Further research is required, but for now I will surrender.

I think I was in exactly the same mode - Ive heard that over and over again, and I did the same look for a reference and found none. I didnt spend hours though.

THis would not be an easy thing to test - you would have to gather up a significant number of engines (like > 30), and measure the wear on bearings and crank/cam shafts after enough cold starts without oil pressure to get a good wear measure and quantify. Now measure high mileage engines and compare wear figures of merit.

Ill guess that no one has done this on modern engines/materials. I dont think such a test on vintage engines would be relevant, given advances in metal hardening, etc.

I think this is lore that got embedded without ever being measured. On the surface, it sounds so feasible. You can just HEAR those bearings getting munched up with no oil pressure. But an engine at idle only has the load of the moving engine parts on it to first appoximation - not a large load compared to the mass of the car.

My best guess on the source is the observation that stop and go driving leads to earlier failure of engines that highway.,,,from there one presumes more startup cycles....so startup equals wear.....

,,,and just to throw another can of worms into this barrel of drunken monkeys....how about those commercials where they run the engines without oil for several minutes...?? Does residual oil on the bearings stay protective for several minutes ..Im not sure.

Champion makes your super tech filter as do they make for other companys. I bet they make them for Mercury too.
The super filter (champion) was high as far as filtering.

Heres the link to a more detailed study......My guess is your on the right track .
