Oil Extractor question - level or slope ?

Getting ready to do my first oil change from factory to Liqui Moly @ 3000 mi.

I plan to buy a Pela extractor as it seems to be the most reliable based on Amazon reviews.

Problem is I have a sloped driveway, and no level surface.

Reading posts here, I noticed some have removed more oil by lifting the front end of the car.

Can someone with experience with oil extractors give me some advice about this?

I can go from a few degrees slope to about 15 depending on where I park it, so can I over do it?

a few degrees will be more than enough. no need to go for more.

OK, a few degrees it is, thanks.
