Oil Temp Ran Hot Today

[enzo101]

Went for a spirited drive today. After about 20 minutes I noticed it was right at 300 degrees. Car is a 350R and the outside temp was about 89. Seems like it shouldn't be running this hot. Any help is greatly appreciated.

What oil? Last oil change?

Motorcraft. About 2500 miles ago.

When you say spirited, how were you driving the car? Problem with driving in the high RPM's on the street is that you spend a lot of the time having the engine revving high, and consequently generating a lot of heat, but you probably aren't getting up to considerable speed very often to which the oil coolers can really be effective.

The slower you go while also keeping RPM's high, is going to lead to high temps.

Did you check your coolers to make sure you didn't suck up a plastic bag or something?

300 isn't the end of the world, but in those temps, I think 250 would be a bit more normal. I'm down in FL and see it close to 250 as the temps go up. I'm trying to recall my track temps, all out for 30 mins...... Im thinking closer to 275 ish????

More information please.

300 isn't high on a track, but it is high on a street, even with spirited driving.


something isn't right.

At some places around 100mph but mainly around 40-55 in 2nd and 3rd. I hit redline once and stayed between 6-7k RPMs.

I checked and there was nothing blocking them. I slowed down and it stayed at around 250. I kept it slow until passing two cars and could see the temp gauge rise while being in a lower gear.

Thats what I thought. I was in front so I was getting fresh air the whole time.

Mine gets to about 250 or so if driven like that in mid 90s humid air. I think 300 is too much on the street for the ambient temperatures you mentioned.

I'd say repeat the process next time you are out and about.

If it does it again, then I'd look more into it.

Agreed. Unfortunately one time isn't a great indicator of something that is SO incredibly volatile depending on the situation. Even wind direction can cause weirdness with stuff like that. I know it's silly but that's why drifters used to run no fascia so the radiators and exchangers could get airflow. D1 has figured that all out now though.

Damn. You mean I'm gunna have to drive like an ass up a mountain again? Well in the name of science I guess I can. lol

That does seem pretty high.

I had my car on track and it was 91 degrees, at decent altitude so the cooling density wasn't great. When I was really pushing it, the car saw 274 at the highest, otherwise it would roll around 255 or so.

Driving around town in traffic my engine oil temp is between 90c-98C (194F-208F) Outside air about 25C (77F)

I have never seen more than 130C (266F) at the track. Keep in mind I am in Canada so in the summer it does not get very hot here.
