[10-ton]

Anyone used a pre-oem cat long enough to have any feedback on how it behaves in the winter.

10-ton - I can't comment on the Cat, but I ran my Racor 660R on the frame rail all last winter (without the heater hooked up), and it was fine. At one point, the truck sat in 0 degree weather for 3 days straight, and started right up on the third day, early in the morning. I do run an additive at all times (FPPF).


I'm thinking if you're getting a winter blend already, then an additive, it has to be pretty darn cold to cause problems. Hope this helps.

That's good news Smitty. Currently my hangup with extra filtration (not under the hood). Think I'll wait for a few more reports before committing and/or do a bit more research on the topic.


My problem is living in Albuquerque where it seldom gets to 20 F and then heading North with 45 gallons of ???. I haven't tracked down a refinery person around here to find out just what blend we run in the winter time and over what period of time. The folks at the truck stop I use just look at you with a blank stare when you ask them the question.

If you need a heater option i have a few i'm working on for my kit. they are made by CAT. racor has some to but they cost a bit more.. i still think you'll be fine w/ winter fuel but i don't live where it gets below zero so i can't honestly say!

After a period of time wouldn't fuel returned to the tank and recirculated warm up the fuel in the filter too?

I would imagine if it can start, you should be okay.

i believe the gelling problem will decrease the longer you run the truck for the reason you stated. however i have never measured the temp of the fuel coming back from the engine when its very cold out yet.. i don't know how much the lower temps will cool it before it mixes with the fuel in the tank..

You could always keep some of those battery powered heated socks handy & if the filter ever jelled, you could slip one on for a while till it heated up... Yes?

Regarding the CAT pre-oem and winter. I would highly suggest using good high quality fuel such as BP Diesel Supreme (if available in your area) along with a double insurance of a high quality winter diesel fuel additive such as Primrose 409. A high quality winter fuel additive will tie up free water preventing fuel filter swell/restriction plus reduce filter clogging enabling trouble free operation even in sub-zero temps. Also the CAT, even tho being an effective 2 micron filter, flows much better than a comparable cellulose 10/20 micron filter.
Moreover if you have any question with your winter diesel fuel quality, additize...
