Tunes Engine/Oil Temp

I just came back from Florida on vacation. Ran a canned street tune the whole way there. Loaded Drew's street tune for the drive home and WOW!!! The difference is night and day! I do have some questions about my engine oil temp and coolant temps. Most of the drive the oil and coolant had a 20 degree separation. The oil could be at 197 and the coolant would be 177. What are the parameters?

Re: Tunes Engine/Oil Temp

The typical rule of thumb is 10 degrees difference. I recently purchased the street king tune from Drew and like it so far but have noticed at times my EOT and ECT were up to 13 degrees off on my drive yesterday from Vegas to LA. I feel like his tune is helping keep my Coolant temps lower then they usually are which in my opinion can only be a good thing if it's in the 170s range like yours and I also noticed mine was. Curious to see others thoughts on this.

Sounds like it's time for a new oil cooler with deltas that high

Re: Tunes Engine/Oil Temp

What's the average EOT it should stay at or range between Jgman141?

Oil temp and coolent temp should only be 15 degrees apart at the most when the truck is fully warmed up. Some will say 10 degrees but I don't think that's to big of a concern.

Re: Tunes Engine/Oil Temp

Sounds like you need a new thermostat first, I would install a new one from ford and then check it again, operating temp should be 190-195 for coolant

Re: Tunes Engine/Oil Temp

Yup. Get your coolant to proper temp before you address the oil temps.

Re: Tunes Engine/Oil Temp

As the last 2 said, your oil temp is fine, indicating your oil coolant is in good working order. Your thermostat is what's not operating correctly

Re: Tunes Engine/Oil Temp

Thanks for all the feedback for what appears to be the same issue for myself and txdueselmech84. My truck dies stay less then 15 degrees apart always and usually within 10 but mu ECT is staying around the high 170s to low 180s sane as my EOT for the most part. Seem odd? I will monitor them again on my 4 hour drive back to Vegas tonight also if I do need a new Tstat and that's the reason the ECT is running low can it create any other issues or symptoms that I would notice? Thanks for all the help gents!
