bpd winter oil temps

Anyone with a bpd kit, what do your oil temps look like in cold weather? Just got mine installed without the oil thermostat, eot was hovering around 170, ect 190. Outside temp was 45-50. After really getting on it on the highway I was able to get eot to 190.

Slightly concerned with the low oil temp. I've read some people putting cardboard in the grille to help, but where? Also thinking about a cold weather front if i have to.

Might not be a bad idea to install the thermostat

That is a possibility. I will if I have to. When I spoke to bpd before purchasing, I was told I'd be okay without it. I will call them tomorrow but looking for other options

Mine runs about 170 eot/204 ect around town and about 186 eot highway with similar ambient temps. I have one of the first cold weather kits and I know my thermostat isn't holding temps but it's never seemed to be a problem, even in much colder weather. I'd have to get a completely different thermostatic unit to change it but that's quite a bit of work and I just don't see a reason at this time.

Thanks. Just out of curiosity, about how long would you say it takes to warm up? This morning it was 32 when i started my truck. I let it idle about 10 mins and the eot was in the 130s. After about 10 more minutes of driving it was in the 160s and pretty much stayed there.

I am going to see what i can get with some cardboard up there. It will probably take some messing with. Thinking of starting out with it in front of the radiator, just behind where the oil cooler is. I found a post on another site last night where someone with the same setup claimed he got his oil temps 20* higher with cardboard. He just said it was if front of the radiator, no other specifics. It was in a much cooler ambient temp, so I'm pretty sure it will work unless he's just bs-ing. If i get it figured out I may even upgrade to a piece of sheet metal.

Yeah, even in Orlando, with outside temps at or below 60, oil temps stay low. I use the FIA winter front to solve the problem. The FIA bug screen comes in handy the other 355 days of the year.

Wow, even at 60 huh. It sounds crazy to use a cover at those temps, but i guess using this cooler without a tstat that is just the way it is.

Had a little time to mess with cardboard last night. This morning eot was up 10* from yesterday, so some progress. Going to keep playing with it and make a decision after that.

Cardboard in between the coolers. Have to do it every year below 0c

I haven't thought much about the oil temps but this thread got me thinking. I'm in SoCal and we've had a stent of cold weather lately. I always leave my truck plugged in so it rarely starts at super cold temps. What exactly are you guys doing to help increase oil temps? Should I really be that concerned? I am running synthetic 5w-30 currently.

Thanks
Joe

I'm hoping someone with more info will answer but from what i understand colder oil temps keep the oil too thick so parts don't move as well as they should possibly losing power (fuel economy) or even accelerating wear. I thought i read somewhere that more fuel is used in an attempt to bring up eot, but i could be mistaken. Also without coming up to higher temps, condensation can build up in the oil. One more thing, colder thicker oil will not pass through the filter easily, so the bypass valve opens and oil won't get filtered.

The sweet spot seems to be above 190. In reality, a little lower is probably not too big a deal. Ect is more closely related to fuel economy, just trying to get it closer to "normal" operating temps.

I have tried a piece of cardboard in front of the radiator with a couple zip ties holding it to the battery cable to keep it from falling down. It helped keep eot slightly higher, but still took a long time to get there. Tomorrow i may try it in front of the intercooler.

If I run the defroster (it turns on the A/C compressor) it helps warm up the oil from the added heat.. The cooling system on our 6L is fabulous so we can pull that huge Camper over that steep mountain grade.. but, for plain driving in cool/cold weather it works TOO well.

The oil in a 6.0 is also used as hydraulic fluid to power the injectors, hydraulic pumps don't like thick oil. With 5w40 you are probably ok but I would not run 15w40 unless you are in a very warm climate. The oem cooler is more of a temperature regulator than it is a cooler, it warms the oil in cold temps and cools it when it is hot. The ideal setup would be an aux air to oil cooler while keeping the oem cooler, like the trans uses.

How so? Common sense and physics proves otherwise. Warm coolant through cold oil in the cooler will warm the oil til oil temp exceeds coolant temp then the reverse happens.
