for anyone that is interested this is the bypass system I use. there are others, I just decided on this one because of the type of filter, and other info I read about. they used to be called oilguard but looks liek they are jumping on the eco thing to get more exposure.

centerpin and mr ed,
Please elaborate on the statements of more soot and fuel dilution in the later DPF equipped engines. You have a better controlled fuel injection compared to the earlier produced engines and the mileage is similar between the 2 generations of engines. So please explain how these conditions occur.
Thanks,
Randy

What is all the noise about warranty. i had my 7.3 in for warranty work a few times and Ford did not even mention service. Now 11 years and 140 K miles later it is still rattling along.
Common guys someone come up with the scoop on all the "void the warranty" posts.

An oil change on my 7.3L takes about 13qts at $11/gal or about $33 in oil and another $10 for the filter and I have changed it even with heavy towing about every 4,500miles. I have done OA (13 so far)since new and the oil is always good, but don't do OA to extend the interval since $40 every 4,500 miles is reasonable for what I use my Van for. I use OA to check for potential problems such as turbo bearings going and to watch how well my air filter is doing and to watch for fuel/antifreeze contamination issues.

Another interesting read Lubricant additive addresses fuel dilution issues with biodiesel blends. As I understand it some states already mandate B5 blends, so something for the DPF crowd to be aware of.

My owners manual says 7500 miles but most of the miles on the truck are towing so I change between 6000 and 7000.

IMHO it REALLY depends on your driving conditions both environment-wise and also how you work your TV.
I live in NW Ohio...the weather is not extreme here either way. It's not blistering hot for long periods of time nor is it arctic cold for long periods of time.
As for how I work my X, it really only tows the TT and that's it, any other time it's a "normal driver". Added to that, it never does "in town" driving with lots of starts and stops or trips where it doesn't run long.
I live in a real small town (one stoplight), and almost anything we do causes us to travel to a bigger town 10 miles away...so highway driving is the norm.
I normally change mine every 7000 or so in my X...

I have a 7.3 Ford and I do mine between 7500 and 8000. Ford dealer said I could go longer, but it takes me close to a year to get to 8000 miles.
I use Rotella and have noticed zero oil consumption to date.

Changing oil at 3000 miles or every 3 months (which ever comes first) is pure marketing by the Quickie Lube industry to increase sales. It's almost as brilliant as the marketing guy who dreamed up the scam to double shampoo sales. "Shampoo, lather, rinse, repeat"
I wonder if there are really any people that would change their oil after 3 months if they only drove a few miles???
