In the 90's they were refueling the cars so 6 seconds was considered fast. But here, they could run through the pits as fast as the car could go.
Now, the pit stop world record is 1.82 seconds, but pit speed limits have increased the amount of time spent in the pits compared to 90's.
If you get on the highway, set cruise control to (pick a MPH) and stick with that MPH you are likely to burn less oil. And if that MPH is a sane speed, your engine will run cooler and you will exceed EPA mileage.
If, on the other hand, you get on the highway and treat it like a race track...
The pressure the oil pump creates just cause oil to flow through the engine.
As long as the bearings do not get all of their oil thrown out and become dry, they remain lubricated.
Lubrication has to do with oil viscosity not oil pressure.
I can tell you that in my 1995 Ferrari F355 that the oil pressure stays at 75-80 PSI on track up to at least 300ÂºF. This car does have an oil cooler built into the dry sump system. In recent times, I try to stay under 275ÂºF.
But that if I have to pit without a cool off lap, the idle pressure...

It is done all the time in engines with dry sump systems.

Had more to do with Scott Kalita than airborne-edness.
In the distant past, stock block rule essentially meant stock heads, too.
When unlimited amounts of money get involved, the heads end up racing heads, and the stock block has more displacement, more boost, and thereby higher power.
Shame about Mansell.....

I used to get 96 and 104 at about $6.00 per gallon at the race track.
But the quantities used per year, of this kind of gasoline, is less than a single refinery's production for a single day (maybe a single afternoon).
