Grades based off general A, A-, B+, B, B-, C+, C, C-, D+, D, F scale
A being the highest grade and F being the lowest.
Better filteration earns a higher grade, better construction earns a higher grade
lower prices earn a higher grade, higher surface area and volume earns a higher grade.
Final grade is calculated the same as a GPA based on the 4 point system
The higher the final grade, generally means a better overall filter.
Catagories are weighted by importance, calculated weights are listed in column heading
Filteration and build quality are somewhat objective so you can make your own judgments

Trust you read the small print...

In summary, in 2011 Fram made the most effective oil filter for a single Chevrolet light truck spec LS1 engine, as tested on the kitchen table by a bloke called Aloicious, from the Internet

[biggriffin]

Also them all Yankee filters.

[05omegav6]

I was half expecting to see Fram had sponsored it...

[Broomies Mate]

Genuine question;

What difference would any of that make to a standard road car which was maintained correctly and servicing schedules met (if not beaten)?

Surely bugger all?

[chrisgixer]

So what are we to make of this Mr Mog?


Along with previous posts, iirc, there seems to be a great deal of interest in oil filters.

Whyzatden?

The cynic in me would suspect someone works for Fram, or its parent company

[Broomies Mate]

Has anyone on here ever cracked open a filter and seen what it, erm, catches?  I've had the paper filters and not seen anything on them, so, and this is a crazy stupid question.... why bother filtering the oil?  Surely all the heavy globules of shite are just going to drop to the sump anyway and that's what the oil pick-up strainer is for, right? 

Surely if the engine is serviced well, the oil should be changed out well before it's useful days are gone!

[05omegav6]

The idea is to trap all the particles in the oil resulting from wear and prevent them from reaching anything critical such as the cams/followers. The pump supply is filtered by the strainer, and the output side is the forced through the fine filter on its way up the block...

oh dear.  maybe i'm wrong but perhaps this is why people keep leaving the forum.  i simply post a useful link comparing well known makes of oil filter.  i do not work for fram what a stoopid suggestion.  nor did the person posting the article and doing the tests. 

what i think yoiu will make of it sadly is that oof knows best and trade club filters are the only ones to use and i should shut up.

Perfcect explanation, and which I do understand, but even on the paper filter, I've not found an iota of shite.... so, with modern engines and modern oils.... is the filter really necessary?

Air filter, I get - You don't know what is around the corner (road sweeper kicking up loads of crap for example), but in a closed system, if it's properly maintained, should we require a filter?

yes http://www.gmtruckcentral.com/articles/oilfilterstudy.html

Easy there Tiger.  You have actually prompted me to ask a reasonable (in my mind) question..... which was, are filters necessary?..... I don't see any reason why one filter is better than another.  As my experience proves, I've not seen anything other than oil on a filter.  So why is it there?!

It was a serious question.

You may remember my posts on bad experiences with cheap filters so that may affect your reply. But, again, it was a serious question.


....if you'd care to answer? it is a forum, so seems a fair question to me.

yes its a good question ordinarily i would expect you to get sarcastic condescending responses here but they seem to have picked on me for the time being.  I would say the answer is definitely yes they are necessary, have a look at the vid i posted above, and the study that was in the OP.
