My past life is 31 years at an aircraft engine OEM in the engineering and customer support areas. Best advice was always to follow what the OEM says as per FAA, CAA JAR etc rules and not reinvent the wheel if you want to keep your license.

These cars are known to live long and wonderful lives by following the factory recommended intervals and using the recommended type and viscosity of oil. No second guessing required, but as always- do what makes you happiest.

 

-exactly (Lucky for me there are no FARs for maintaining cars in a "Superior to factory recommendations" condition!)

 

Let's put it this way ... if you're going to bother filtering, you might as well filter well.

Then you have to be concerned with flow rate, burst strength, bypass pressure, filtering ability and whether the filter has a anti-drainback that operates as the manufacturer expected.

Not all filters combine these equally well.

A filter spec'd for a particular application can vary widely between vendors. In one example, out of 54 filters for a single application that were cut open the filter media varied from a low of 81 square inches to into the hundreds of square inches.

 

I'd hope that even the worst of the worst filters are up to the task of a 3K or 5K mile change interval, given that the Jag filter is good for 10K.

 

Id guess that Jiffy filters are the worst of the worst.

 

Technically they are made by Fram/Honeywell....

Whatever you DO NOT use Fram filters. They are acknowledged by everyone as being the cheapest filter on the market. Limited filter media, paper by pass valve etc. This has been backed up by by many valid test data. There big claim to fame is 300 (I think) psi burst strength. An engine seldom goes over 50 to 60 psi. Totally worthless quality standard to use. Typical false advertising.

 

FYI NAPA GOLD 7302 is a WIX , Made in USA... I use this brand on all my vehicles.

I really hate being made to stand up for Fram, as I will agree that there are superior products out there. However I think this bashing of a brand without any valid data to back the claim is foolish to pass on.

I would like to know what bench/lab testing has been done to prove Fram does not meet or exceed OEM requirements. Who is that proverbial “everybody knows”?

So far as I have found, the “Fram is bad” gossip is generated by a disgruntled few, and never do they give you the full story like “I built a motor, and put in a high capacity oil pump, and now it blows OEM filters” kinda stuff. Or for all I know, they work of Champion or other maker and use the net to steer customers to them. After all, paying someone to rile up a forum is money in their pockets with no heavy marketing costs.

I can invalidate 95% of the complaints out there (and most of them are 5 years or older now) with ease, just with basic mechanical knowledge.

So it comes down to I'd like to see proof. Without it, I see Fram bashing as just rumors, propganda and wives tales.

Go on You Tube. There are dozens of unbiased comparisons vids with with virtually every other filter made. Just like STP, Microgard etc. they are all the same low price/quality filters. No one is bashing anything I'm simply using side by side comparison.
