1930's Packards - need advice on oil filtration

Read our primer articles on High Mileage Oil, Synthetic Oil and Kinematic Viscosity

G'day all, I have over 60 old motor bikes from 1907 to 1970, also 8 Packards from 1927 to 1956. The bikes are not a problem as they leak oil from every conceiveable joint and every ride involves new oil to top up. The Packards, Rolls etc are the big worry as the engine rebuilds are up to $20,000. The Packards run by-pass filters from 1927 and I would appreciate some advice on the filtration size ( I have heard 6 Micron but nothing about efficiency). The 1938 Supers and Twelves ( I have 3 Supers and Lionel Barrymore's Twelve) run a full flow filter (i'm guessing 10 Micron). Later Packards run by-pass filters Wix/FrAM napa 1080. MY QUESTIONS ARE?
1. Does anyone have any factual advice on the efficiency of the by-pass filters typically fitted to these old cars.
2. What efficiency inmprovement could I expect in switching to a modern full-flow or by-pass system. I need the response to be a comparative factual statement, not merely a sales pitch.
Finally, There appears to be a very solid level of knowledge on this site and I would appreciate any advice on the subject.
Best regards from Down Under Peter Toet

How many miles are these vehicles driven annually? Do you perform oil analysis on any of them?

Here is a link for the Wix filter look up - http://www.wixfilters.com/filt...=51080&Submit=Search

Wix 51080 (application: all 8 cyl Packard models) - Beta Ratio: 2/20=6/20
Nominal Micron Rating: 21

Hi Jim, Thanks for the response. Most of the Packards and other vehicles probably do less than 100 miles per year. I do not conduct any oil analysis. I try to drive the vehicles for at least 20 minutes to warm them up and limit sludging. My concern is that occasionally take a vehicle on a few thousand mile caravan. Peter

Hi Jim, I have been onto the Wix and industry site but am not able to locate the source of your ratings. Are those ratings for the replaceable element type filter or full flow. The micron rating is worrying also the Beta ratios. Are they for single or multi-pass? Sorry to appear obtuse but i am trying to suss out if thre is a better available By-pass element for our old Packards. Thanks Peter

Peter the Wix link above allows you to cross reference with a Wix part number any filter you may be currently using.

Here is the detail for Wix filter number 51080 - http://www.wixfilters.com/filt...etail.asp?Part=51080

If this is the by-pass filter size you need you might contact Wix directly to see if there is a model, with the same dimensions, that has better specifications.

G'day all, Does anyone have a link to sites which might lead me to find a reasonably efficient replacement element for the Wix/Napa 1080 ( 51080) or C134PL ( Napa, Fram, Autozone, Krgen, extra Guard.) Does anyone know where I may be able to obtain some Beta ratings for these filters. Or will I have to fit an Amsoil or equivalent spin-on type HE by-pass filter system. Best regards Peter Toet

in my experience, you'll not get any Beta values from Amsoil.

That said, I did find a report (not official) for motorcycles filters done by an ExxonMobil lab guy. Enlightening.(good results btw)

I'll try top find it again
