Granted F1 is tougher on the oil than Indycar.
Indy cars DO use off-the-shelf oil; it's written in the regulations. I can't remember the exact wording, but the regulations mention something like "readily available to consumer" or something. F1 isn't too much harder on oil than the Indy cars anymore. Although neither sport rarely, if ever will give exact power figures, Indy engines make somewhere in the neighborhood of 700 hp, whereas the F1 engines are estimated at around 600 hp (engine only, not including the electric motor), although this season especially it varies wildly between engine manufacturers. That works out to about 318 hp/liter for Indy (2.2L engine), and 375 hp/liter for F1 (1.6L).
