Hey guys! Planning on tracking my 2016 F-Type R for the first time this weekend and I wanted to do an oil change before I do. My buddy runs a N54 powered BMW and his track buddies recommend adding an extra 0.5 to even a full quart for track to ensure the oil pick-up doesn't run dry on long sweepers. Was hoping for some advice on if that is a good idea for the F-Type too.

 

No direct experience on this, but I probably wouldn't recommend it. These cars seem to be particularly sensitive to variations in oil volume.

 

Thanks Hell Cat, thats what I was worried about too but also thinking it shouldn't hurt for the weekend.

 

When you add too much oil, the excess oil will go towards the crankshaft, and as the crankshaft rotates at a high-speed, the oil is mixed with the air and ‘aerates’ or becomes foamy. This foamy texture of the oil acts like a bad lubricant, and the oil is not pumped effectively. Over time, the engine will be starved of proper lubrication

It is better to run .5 too low than .5 too much. It would be a horrible idea to overfill the oil.

NOTE!!! I am not saying to run too low. I'm just saying too much oil is a bigger problem than too little oil to a point. Obviously, running way too low will be catastrophic, too.

Run the exact right spec. Run what Jaguar recommends.

 

Is the F-Type oil pan baffled? The baffles lessen the chance of oil starvation.

We instructed an F-Type owner at Watkins Glenn back in 2019, no issues with stock components...

 

Yes.
From the AJ133 Technical Training doc:
"Reduced oil foaming • Structural baffle plate".

 

I suggest flushing brake fluid and servicing brakes prior track.

Also, don't over-inflate tires - as you drive tire temperature (and pressure) will go up. If you start at 38 PSI after few hot laps you might end up as high as 45. If tire pressure gets too high, tires will start losing grip.

 

Appreciate the info and advice .. Im not going to take any chances to upset anything.

 

I would have an extra quart with you and check during track time and add accordingly.

 

Owner's Handbook: Oil overfill - Do not drive the car.
As zach05855 says, you can't pump foam.

 

It’s all been said, but: Add extra quart...BAD IDEA!

 

Screen shot below from the 2021 owners manual. I find it confusing. It seems counter-intuitive to increase pressures for very high speed driving, and on the other hand, they suggest much lower pressures for "closed road" conditions which I assume means track conditions. I won't be tracking my car nor driving it over 174 MPH but I assume that their "closed road" example is maybe for autocross or track conditions that don't allow ***** out straightaways where your car could reach speeds in excess of 174 MPH.

 

Its easy:

track driving with high-G forces, heats up the tires more.

High speed Autobahn driving doesn't increase pressure as much. BUT stability is better with less sidewall flex. <--- which I'm sure isn't much with 20" wheels

The important thing is 'hot' tire temperature. On our other car, the manufacturer specifies a higher COLD inflation on street6-driven situations, but suggests letting air OUT (cold) for track.

If you ever watch NASCAR, they start low after a tire change, with the front splitters dragging until the tire temps increase.
