SUCCESS ! Motorguard installed and functioning

[96 Cherokee]

Just got the thing installed this afternoon and it appears to be working fine. I "T"ed off the oil pressure sender and ran the filtered oil back through the oil filler cap. I am suprised how much oil is flowing at idle. I thought the flow would be smaller, having to go through that tiny hole in the restrictor.

Ralph, what determines when the TP needs to be replaced? I know your recomendation for 6 cylinders is every 3000 miles, but my Jeep is a rural mail route delivery vehicle and that is severe service IMO. Stop and go all day long and a lot of idling. Approximately 20 miles of my 90 mile route is gravel road. Will the oil flow slow down when the filter gets dirty?



Now I need to find a way to get a Motorguard squeezed under the hood for the tranny fluid.

The instructions that come with the Motor Guards are over 30 years old when engines ran a lot less efficient than they do now. In those days the oil got black fast because of poor carburetion. As long as the oil looked like new and the element wasn't hard as a rock when you changed it you knew you were changing the filter often enough. It's more complicated now. On gasoline engines you don't have the soot to tell you you need to change the filter. In the 60s we just recommended that the filter be changed every 2,000 miles whether it needed it or not. Since the TP is very effective at removing water it had to be changed more often in cold weather. It's kind of a guessing game. I go by the look and feel of the oil. Here in the Dallas area you have to watch out for oxidation putting a coffee color in the oil or viscosity increase that you can feel.

OK, thanks much for the information. With the Amsoil dual remote bypass I just removed, 15,000 miles was the maximum OIC. Just got a UOA report from Blackstone a few days ago, and the report showed that the 5w30 Series 3000 diesel oil had thickened up to a 40 weight. Not good in the winter. I'll keep an eye on it.

Don't forget to post the UOA in the UOA section.

Mileage isn't the best method for determining filter change interval in a delivery vehicle. Monitor fuel consumption or install a timer. Every 100hrs or 100-gallons would be a better choice and reasonably consistent. You can UOA the oil prior to the TP change to adjust the fuel or timer count for you specifics.

100 hours would be about 1800 miles, or less than 4 weeks. I would like to post the UOA, but it's in PDF format, and I am not a computer oriented person. Means I am technically limited and don't know how to do that. In the past some folks on this forum have given me tips on how to do it, but it's over my head. It would take a while to hand type the whole report as there are 3 prior UOAs on this vehicle also on the same page. I have seen where some have posted the Blackstone report with the the owner's name and address removed. If I could do that, I would post sure post it. I just figured that 15,000 mile OCI was over 800 hours. I guess that is not bad, but if this TP filter will mostly eliminate complete oil changes, I would be tickled pink. Thanks for the suggestion.

Just type it out. Take someone else's UOA data section and then just edit in your data. That way, if the site that you post your UOA on goes away, the data will still be here for others to look at.

I agree, steal someone’s text that is in the same format as yours. Open word and acrobat next to each other, and change what you need to. then paste it into a new thread. No reason to work harder than you need to Just don’t tell who you stole it from so they won’t be able to sue you for plagiarizing.

Have Acrobat, but not Word.

I use notepad. It is part of the basic programs under "accessories." Just highlight on BITOG, paste into notepad.

Here is "TOMJONES76" UOA Universal Format that I copied and used. Tom Jones Universal UOA format

Just Highlight it. Copy it. Paste it into Notepad. Then put in your numbers and paste it back. Use the "code" function if you want to keep your spacing from notepad. Then save it in notepad for adding another row for additional UOA's. Once you have it in your computer, it is not that bad. The copy and paste feature is the only way to go to save yourself major keystrokes.

Its a matter of using a submicronic filter and getting the right amount of new oil added. Additives last a long time in clean oil. I have used the Frantz Oil Cleaner since 1963 and the Motor Guard Oil Cleaner I was experimenting with extended filter change intervals. I get right to the problem. If my oil is running too hot I will install an oil cooler. If the system didn't work I probably would have figured it out in over 40 years.
