Since I am running synthetic oil and it is supposed to last much longer, could I just replace the filter and top off the oil at about 6 or 7k miles? I've been thinking of adding the bypass oil filter because they swear you can run 10-15k miles on your oil (seems like it will pay for itself in a year or two). But if the synthetics can run 10k any way, then why couldn't I just clean up the oil that's in there (aka, new filter) and run the oil longer? Thoughts?
I'm of the same mind as these guys. I just dont risk it and change at about 5k. Recently there was a huge debate up in the 99-03 section though and there's a bunch of guys up there doing 10k intervals. I'll try and find the link.
Again, not saying I agree. It's just an interesting read. Some of these guys oil samples make a guy think.
Thanks for the link - really interesting read. I've always heard that the primary reason for changing oil is that it is dirty, not necessarily worn out. My Blackstone analysis came back really good and even they suggested longer intervals (I recognize this is not actually related to my engine but refers to the oil). So, if the oil is generally in good shape but is just dirty, then doesn't it make sense that you could just swap out the filter and clean it up a bit? Especially with a synthetic oil in there? It seems to me that is all that a bypass filter is really doing anyway. So you might double the life our your oil by swapping out filters at 5k an thereby reduce the cost of the maintenance dramatically over several years. Hmmmm...
I know Glenn was having an issue with his T6 shearing down so be went to schaeffers. My oil analysis come back great from the T6 as well. The shearing and soot are 2 of the biggest concerns with extended OCI's. And soot has a very small micron rating making it very difficult to filter.
I've read that Jim has seen guys getting 250k+ on stock injectors all while using the cheapest diesel motor oil available and changing at 3k. To each his own, but for my money, shorter OCI'S are relatively cheap peace of mind.
What's that line from Tommy boy? They put the guarantee on the box, cause they know they've sold you a guaranteed piece of $h1+. Lol

Well, heck, I'm only 18k away from 250 on my stock injectors, so maybe it's a moot point! lol Kind of like doing burnouts before you replace your tires!!!!

I've been running amsoil in my trucks for years. 15,000 miles between oil changes. I don't do samples all the time, but when I have, they've always come back good, except one time I had a little aluminum, which was the result of a turbo failure. The HPOP is hard on the oil for sure. Amsoil says you can go 25,000 miles under normal driving conditions, but I choose to go with the 15,000 mile changes, which is what they recommend for severe service. 388,000 miles on my 97. It had 116,000 miles on it when I bought it. Other than turbo, injectors, oil cooler, and water pump, no engine problems at all. It does leak some oil now though.
