It seems the oil doesn't last that long I would like to run 5w40 t6 and see if it makes a difference. I think it will...

 

I was curious because I'm lazy and wanna change oil less so I rather run synthetic. All the other good stuff that goes along with it is just a bonus haha

 

I used to run T6 a lot but the samples kept coming back saying the oil was shearing down. Schaeffer's is a blend.


I went 7K (didn't mean too ) with the Schaeffer's and the oil sample came back great. IMO, if you want longer OCI, put a oil by pass filter on.

 

So I've heard some synthetic brands recommend there oil to go up to 15,000 miles or once a year. What is this bypass system you guys keep talking about. From my understanding all filter systems should bypass if a filter gets clogged some how.

 

This is an extra filter that filters 10% of the oil flow and filters down to something like 2 microns. Its not meant as a stand alone system, just a system that cleans up, in our case, the soot and the small stuff. Look at FS-2500 Bypass Oil Filter System

 

My 97 would use 2qts in 3k miles with rotella or delo 15/40. After I switched to motorcraft it stopped.

 

Mobil delvac one 5 -40 in my 94.5 F350 7.3 and all my diesels , tractor, mower,car
Called there tech line and they said I was good

 

I'm going to proclaim Glenn as the king of oil know how...

 

I don't know about that Corey, LOL.
