[DeTomaso] Remote oil filter setup

[Ken Green]

Regarding frequent oil changes, I hate those seconds before the oil pressure comes back up.  I think that one advantage of synthetic oil is that it is so much better that even after 10,000 miles, it's better than dino oil.  By avoiding frequent oil changes, I avoid the wear of starting an engine with delayed oil pressure.  I realize that people are getting excellent engine life with frequent changes, so the wear is probably not an issue, but I got 180,000 miles from my last car, with 20,000 oil changes in Mobile 1, and it got better mileage at the end than when I bought it (and it was a Regal GS, not a Toyota or Honda).  The oil stayed so clean, that it was hard to feel like changing it.
 
I wanted to use Amsoil in a diesel about 20 years ago, but with the blow-by, it's gets dirty just like dino oil, but was 5 times the price.  So, I tried the Amsoil bypass filter, and paid for oil analysis.  It actually worked, and the bypass filter kept it clean enough (according to the oil analysis) to run for an extended period.

My 2-cents, and it's only worth about that, is that all gasoline powered production 
automobiles currently being produced come with only ONE oil filter. Yet, they all offer 
anywhere from 50,000-100,000 mile warranties.  Some don't even call for a tuneup until 
100,000 miles.  

Anyway, oil and filters should be changed every 3,000-6,000 miles (always err on the side 
of conservatism - doesn't hurt anything to change it too frequently). I've torn down late 
model OEM engines which showed nary any wear on bearing surfaces after 
120,000-150,000 miles. This is the result of regular and frequent oil changes.

So why would you want two filters? To extend/double the interval between oil changes? If 
it's a redundant system (two identical filters inline) the first filter will catch most of the 
contaminants and begin to restrict flow to the second filter and subsequently the engine. I 
suppose if the first filter has a bypass valve, which most do, then the second filter can 
catch whatever bypassed the first filter. But it seems like a lot of unnecessary complexity, 
as others have already stated.

I would merely use a filter without a bypass valve and change the oil regularly. Or for added peace of mind if you're concerned that the filter is getting "full" and losing it's flow/filtering capacity, change your oil every 3,000 miles and change the filter at 1,500 mile intervals so it's only in service for half the time/mileage between oil changes.

YMMV!
