Which means you are payings twice as much for the stock Motorcraft FL-820S.

Since it's a Pure one cartridge with synthetic drainback valve (the S) in a Premium casing.


The Motorcraft is definitely then number 2 choice. $3-4 for an excellent filter.
The only drawback is just like every other filter on the market sans one. It's only tested to 3GPM when our oil pump surpasses 10GPM at 5500rpm (think about 6k, 7k, 8k etc ) That's a heck of a lot of potential oil being forced through the small bypass valve. (unfiltered and superheated!)
Also with an oiling system as efficient as ours that 3GPM is likely in the 3000 rpm range. Maybe lower; Yikes


I run a K&N and it has given me the best oil analysis results.



Hey Demon - I was surprised at how good the motorcraft really was from the last thread! Do you know - is the following chart correct?



If so it appears the motorcraft / pure one cartridge not only filters well, but has great flow capability too.



Well, Scott's graph confirms my Mobile 1 filter choice. Couple that flow rate with the best filtration efficiency, greatest capacity, and highest burst strength of the bunch, and you have a winner.

BTW, the K&N flows even better, but at a small sacrifice in filtering efficiency. So, it doesn't filter quite as well, but it's filtering more of the time (less time in bypass.) Also has lower burst strength than the M 1, but still very good. It's kind of a toss up, depending on what you care to emphasize.
