No doubt I could run longer but they don't recommend using the filter for more than 15K so I change it every 10K and then change the oil every second filter change. I believe Mobile1 doesn't recommend going over 10-15K miles. But that is great if they are getting those miles out of it.

Thanks for the details..I usually try to get about 4 gallons an hour thru the shrader valve for my bypass filters..I have a new Huge p90 amsoil bypass filter now, but it is pretty big for 2.4 toyota 4 cylinder..So I may put another pf35 adapter on it..Dam- good truck, but age is making me want somthing sportier..Not nice to fool with father-time? I totally believe in the bypass system for engines, if it cost a whole lot then the pre-oiler sytem is very good too..We bought them for our Cummins gen-sets..Nice..Yup ...
I didn't drain and totally change out the oil until that sump had over 51,000 miles on it .... and it was likely still good then (I have a sample from that drain I still haven't gotten around to sending in :confused2
Blackstone's report forms make it a little confusing - it's the same oil sump from mile 135,283 to mile 160,259 on the odometer and the makeup oil listed is a total up to that time on the last two UOA's, not cumulative (IOW, 5.25 total quarts over 24,976 miles)
Consulting my maintenance log, I see that the entire sump (around 10.5 quarts) was eventually changed out at 186,657 .... so 186,657 minus 135,283 = 51,371 miles on the sump before changing ....
A Motor Guard M-30, modified by Ralph Woods of Texas .... essentially it's a TP filter (toilet paper - I mostly used Scott 1000) .... similar to a Frantz ....
I usually changed the filter every 3K to 5K miles (roll of TP is less than a buck) and added maybe a 1/4 to 1/2 quart of make up oil.
Right now the bypass filter is off the truck - I got tired of changing the filter so often (I'm lazy and I run a lot of miles) ....
I have a centrifuge (Spinner) filter I haven't gotten around to installing yet .... should require less servicing.
Worthwhile investment if you run a lot of miles or hours IMHO ....

Only would I run that far{25K] if i had a bypass filter installed...Even with the Mobil 1 filters..I did not like changing the filter only at the mid-point of service..Everyone wants their engine to last longer..Now I am driving it less so the year time factor comes into play?

Get back to me when they both reach 300k then we will know if there was any damage? Since both these vehicles can easily go that long with 6k mile oil changes on dino oil.

I run synthetic in everything I own.I change every 8000 miles but if I can't get to it before 10,000 It doesn't worry me.Amsoil has a guarantee that if you buy their engine cleaner and then change to their oil with their oil filter, you change the oil filter every 3000 miles and top oil off,Never actually changing the oil,If you ever have a oil related breakdown the will foot the bill in full even if it means a new motor.I shyed away being their products are very high priced

That oil guarantee is about as good as me guaranteeing you will not get ran over by a Pepsi Truck today. I have been around equipment for my entire life and never seen a "oil related failure". Its always a oil pump went out, low on oil, ect. Non of this is oil related, its mechanical failure or stupid operator. It makes the sheep feel better but it really does pay off.
I know of a guy who accidentally put hydraulic oil in his motor after servicing his tractor. Did not catch it for 100 hours till he realized the 5 gallon jug of oil had not been opened and his hydraulic oil 5 gallon jug was down the 8 quarts. Long story short he changed the oil and keep a eye on it and 1000 hours later its still running fine.

Im another thread i have learned that in Europe they have one oil that they put in the trans/hydro as well as engine. Its spected that way! But i think they said a 5 gallon pail of hydro oil is aabout $100.
And i agree on the amsoil stuff.

I have seen an oil related failure once. It was a dodge stratus with a 2.7 L and about 35k miles on it. They never changed the oil on it since new and when we took off the valve covers it was not pretty looking. Black, burn, gummy oil everywhere. This was dino oil.

Well thats neglect. Im pretty sure D.P. was talking about someone who actually makes an effort to maintain thier stuff. If your using amsoil and changing filter every 3k i bet the oil will last basically forever as your pretty much adding a qt every 6k miles.
I would go to say that even if you used a cheap store filter and house brand oil since new i bet you would not have a problem, same as if you used mobil one and changed oil every 10k or whatever.
I have used walmart brand oil for close to 100k (really warren brand) and pretty much fram filters in my ranger. That was pretty much the second half of its life. The last 30k or so has had name brand oil and filters as i catch it on sale at parts places, but still add off brand when burned. It now has 290K on it.

That is not a oil related failure, that is a dumb azz operator. My uncle did the same thing with a 4.0L Jeep. 35,000 miles give or take on that one also. A oil related failure in my eyes is the oil falling apart or failing in some fashion well before normal change intervals or even at it. 35,000 miles is 10 times the normal change rate on dyno oil.

I have used JD 0wx40 and Shell 5wx50 oil with extended miles. The JD has gotten has high as 13K-14K before the lab recommended an oil change. The Shell might have gotten up to 10Kish before I changed it but it was just fine.
How many miles your oil can go depends on your use. One oil change on the truck I had fuel in the oil. The amount was still within spec but obviously you don't want it there in the first place. Fuel had never been in the oil before or since. Why was it present? At the time my route went into a town that had what I called the Valley of Death. The valley had two lane roads and huge amounts of traffic passed through the town during rush hour. The roads were being worked on so which made the traffic that much worse and I routinely would be stuck in stop and go traffic for 15 minutes during a 60 minute commute. I figure that 15 minutes would not matter much since it was such a small part of my drive. Maybe it was or maybe it was not. Certainly there were a few times in the Valley of Death where I was in traffic for 30 minutes or more. That stop and go traffic with low idle speeds gave me the fuel in the oil. My route changed after that oil change and I have not had the problem since.
Oddly enough my tractor had fuel in the oil at the same time. I don't run the mower and thus PTO speed but a few times a year. The tractor would run at 1600-1700ish RPM which apparently was not enough to keep fuel out of the oil. Again it was within spec but I increased RPM to 1800-1900ish and no more problems.
I have never used up the TBN in the oil. Strangely some UOA have the TBN still at 10-12 after very long miles on the oil. Most of my driving now is rural 55 mph roads with very few stops. I think that helps the life of the oil. YMMV.
