80,000 Miles......No Full Oil Change

Posted

That's what I'm approaching now!!!:cookoo::stuned: I've officially got about 130 miles to go before a "full" 80,000 miles without a complete oil change, but I thought I be pro-active and tell y'all prior!!!!!:cool:I plan on taking an oil sample and sending it to Blackstone for analysis at the next scheduled TP change out. That'll be just over the 80k mark, but close enough. I'll post the results when I get them. Those "butt wipe" filters work well!!!:smart:

Works with... The stock OE filter is a full flow filter and a Motorguard / Frantz is a bypass filter that only filters a small percentage of the oil flow.

IIRC, the MotorGuard and the Frantz divert off about 5% of oil pump flow for the bypass filter. Still even with that small amount of oil, the flow rate threw the TP bypass filter averages about 1 quart per minute of engine running at normal operating temps. The OEM full flow filter flows way more than that............it has to in order to lubricate and cool the engine!!

Another option you can try is a Fleetguard Venturi type oil filter LF9028 or Baldwin 7313. These filters are a full flow lube filter and bypass filter all in one. A friend and I are still working on fitting a Fleetguard CH41102 Centriguard Centrifugal bypass oil filter to our trucks. I think this is the best possible option.

So how do you install this? Any none reverse able steps? I don't want permanent change.

Well with the Frantz Filter it gets oil feed from the oil filter housing and returns it back to the oil cap on the valve cover. So you can remove the setup anytime you wish.

For my MotorGuard bypass, I have the oil returned to the pan via the STHB (Self-Tapping Hollow Bolt). According to Ralph Wood (Mr. MotorGuard) the STHB used to be supplied with the Frantz bypass system. Don't know if it still is. I've not heard of it happening on a Cummins engine, but I went with the STHB because I didn't want to risk "misting" the oil via returning it to the valve cover or the cap. I'll see if I can dig up a picture of my return line to the pan.post-7-138698177201_thumb.jpg[ATTACH=CONFIG]2730[/ATTACH]
