Did a search and couldnt find anything. What weight oil are you guys running for track days?

Track day is irrelevant. Motor is designed for 5W30 and that's all you really need. Unless you've rebuilt or replaced all the internals; in which case you should use whatever weight your engine builder recommended. Otherwise, the 30 weight is more than up to the task of anything you can throw at it. A lot of people worry about temps, which is a legit concern on the track, but remember your oil is the proper viscosity up to 212°. If you're seeing temps higher than that, you need to address the temperature, not the viscosity.

I think 5w30 is what the motor was designed for

****, ****, ****...you're right. I meant 5W30. I meant what ever weight the motor is designed for. I misspoke. Thank shineboy...great catch. Going back to edit. Had 40 on the brain for some reason.

All good!! 40 probably wouldn't hurt anything other than a slight decrease in mpg... maybe

I run FR50 in my Coyote Mustang for track days and it holds good oil pressure hot and cold. FR20 runs a little hotter and the pressure varies more between hot and cold. The FR50 is recommended for track purposes because of oil pressure retention to the cam phasers. Didnt know if I needed to run a little heavier weight in the Focus cause of the turbo building up heat.

Run Motorcraft 5w50 like in the RS.

The general rule of thumb is track likes a bit thicker oil, how much thicker is your choice. A 40 to 50 weight is fine. I run a 40 weight.

I run a 10w 40.

Im running mobil 0w40 with a fl400s. Ive been a big fan of this particular brand and weight from experience of past turbo track cars Ive owned.
