AC + Oil leak?

[sh4g]

So I have a new to me 2021 Tahoe which seems to have some form of oil leak, but only when the AC is running. If the truck has the AC running, I'll get a puddle of water mixed with some oil (rainbow-looking surface). However, I drove 2 hours without AC and there was no leakage whatsoever. My engine oil is good as I've checked the dipstick numerous times; everything's good on that side. AC is cold and vehicle drives well. Any ideas on what this could be?

Could it be that whatever component the condensation is dripping onto/running off of has some oily residue on it, but that you're really just seeing condensation? That'd be my guess.

Ok well first off, every vehicle with a/c drips condensate just like your home or any A/C system, so thats your puddle of water. Depending on where you are parking, is it the same spot every time? It could possibly be the surface you are parking on. Is it asphalt or cement, such as a garage or driveway? Is there a rainbow in the rear puddle of condensate drip(from the rear a/c) has ghe driveway or road youu oark on been recently repaved or sealed? Asphalt is an oil so any mix of water or oil will produce a rainbow look. Check the rear puddle and area you are parking and report back

It's just dirty evaporator water.
