Hello fellow V10 Super Duty owners!!

I have a 2002 F350 with the V10, 6 speed manual, and 4.30 gears. I use the truck for off-roading and hauling my Subaru station wagons to the races on a flatbed trailer. My Subarus weigh somewhare around 2700-3300lbs, I don't know the weight of the trailer. I live in the desert south of Tucson, AZ.
For oil, I'm running Motorcraft Synth Blend 5w-20. (Factory Recommended)

I have recently installed an aftermarket Oil Temp / Oil Pressure gauge and I was wondering what is considered too hot for the V10. This gauge just has a bar graph for the temperature, but I can configure the three zone ranges of green, yellow, and red.
I installed a sandwich adapter behind the oil filter and installed the sending units in that.

From my research on conventional oils, 212-230 seems to be the happy range and 250 is the pull over and let it cool down point.

Therefore, what is considered too hot and what is considered normal operating temp of the oil in our wonderful V10s in towing situations?

Thanks!
Ted

 

those numbers match the info in my memory. You’re good!

 

Thanks! 🙂

It’s great to have a temperature gauge to monitor something, but it’s useless if one does not know how to use that information!
i burned up an engine in my first car because I didn’t understand the information I was reading from the gauges. I knew accurate coolant and oil temperatures were valuable, but I didn’t know what the ranges were, so, I was still blind.
Now, I am learning what the information I’m reading means and hopefully, will be able to not harm the engine when I’m pulling heavy loads. 🙂

 

What are your observed ranges so far?

 

So far, I haven't set the ranges on the gauge as of yet. So, I don't have actual numbers!

With the gauge's factory set ranges:
Normal daily driving, it stays in the green range.
Cruising at 65 mph in 5th gear during the summer, in the low range of the yellow.
Cruising at 80 mph in 5th gear during the summer, in the mid range of the yellow.

Cruising at 65 mph in 4th gear during the summer with my Subaru wagon on a flatbed trail climbing a hill, the high range of the yellow to just in the red range.

I do not know what those ranges relate to actual degrees, but that's where it runs at.

I have pegged the red range when I was hauling a friend of mine's 1960 Chevy truck between San Simon, AZ and Sierra Vista, AZ. Long uphill grade. I was in 4th at 65-70 mph (quite a ways in the 4000 rpm range). Coolant temp gauge never moved and I didn't have the ScanGauge yet. So, I have no idea what the coolant temp was at the time. However, the truck evidently got hot because I suddenly lost the upper 2/3 throttle and it wouldn't rev past 4000 rpm. No indication on the dash that something was wrong. Once I let it cool completely down, it was fine and I have never seen that again.

I will get the gauge calibrated sometime this week and will report back.

 

Would you mind posting a link to the setup you're using for oil temperature?

 

I have a picture of my gauge set:

The oil pressure/oil temperature gauge is by Innovate Motorsports. It's their MTX series. It's not a cheap gauge, but it's two in one, fully digital, AND it has an I/O port that you can connect either your computer to, or there is an optional module that allows you to data log to an SD card.
I have this gauge, their Boost/Shift Light, and Wideband gauges in my Subaru WRX. It satisfies my inner geek and I have datalogging when I need it.

I don't have a picture of the sandwich adapter, currently. And...I have my Subaru XT6 today, not my truck. lol I will do my best to snap a pic and post it later tonight.
