That is oil. Can you check the filter or plug for leaks? Have it put up on a ramp, or jack it up and slide underneath after you secured the car properly.

I didn’t see anything dripping, the filter seems tight, it’s parked on a slight decline too - I’d rather not move it until I ring the garage on Monday and have them tell me what to do, potentially get a truck to collect it if there’s too much oil loss
@StevenMiller
You won’t see it drip. When oil comes in contact with water it spreads over the surface and gives that rainbow effect. A few drops overnight are sufficient to make it look like that.
You can check your oil level with the dipstick.
You can also add oil to top it off if it’s too low.
I doubt you need a tow truck for something this small.
I’d advise you get into fixing your own car/being comfortable doing the small things on your own.
@PeterJames4
Right, it’s probably a very slow drip, it did rain heavily for an hour over the past 12 hours, so whatever dripped spread out.
I am comfortable doing most minor things, but oil isn’t something I’d consider doing myself, especially with the car still in warranty and the dealership where I bought it brand-new being the ones who did the change, it’s their problem to look at.
I checked the dipstick (even though the car is on an incline) and it seems full; I’ll check again by Monday morning and ring the garage for advice/to bring it back.
Thanks for the advice.
@StevenMiller
You can change the oil yourself, use a Hyundai filter and the correct oil and keep receipts because I think it’s awful they recommend 7500 mile oil changes. I do every 5k.
I’m changing my oil in between their intervals and hope it lasts a good while. Watch it still pop at 70k or something. If that happens then I should’ve gone with my gut and got me an old Toyota, something tried and true.
Jack it up and look under there, ain’t gonna hurt.
Honestly if you’re capable I’d find out what it is so you know what’s the issue and the shop doesn’t try to pull the wool over your eyes.
@Lashun
I’m not completely against changing it myself, but it could be very messy, and I don’t have the equipment to make it cleaner nor easier. For the sake of €75 they charged, it isn’t bank-breaking money.
Obviously, they screwed up not tightening something, and the car isn’t reporting any faults on the diagnostics, so I think it’ll be fine until Monday sitting there.
@StevenMiller
Ain’t it a crying shame a shop can’t even change oil correctly? I’d be livid.
A drain pan and some cardboard boxes will keep the mess to a minimum by the way and some old rags; if you’re careful, you’ll maybe get a couple of drops on the ground. By far the most annoying is pouring the oil from the pan to like a milk jug; I don’t always have my dad’s 5-gallon jug on hand but I collect the oil and take it to Advanced Auto and dispose of it for free.
@Lashun
Not even need for cardboard box.
Here’s what I do:
- Buy good oil at the specs you need (most likely 5W-20) - Castrol/LiquiMoly.
- Buy a good oil filter - Mobil 1 is my favorite.
- Have a socket set with extensions.
- Have a tool to remove oil filters (the gorillas at the shop make sure only Godzilla can take it off).
- Oil drain kit (basically a glorified catch pan AND a funnel for oil.
Go ham on changing your oil.
Now, not all mistakes are from the dealership - a) the rubber ring on the oil filter can have imperfections which makes it not seal with the car properly and b) it’s easy to miss replacing a crush washer, which will result in a small oil leak.
rainbow = oil or gas. Since you just had an oil change, it is very likely to be oil.
You need to investigate the source but it could be oil dripping from an accidental splash in the under shielding while draining the oil. It’s very easy for oil to get caught in there and you need to clean after. The quick oil change and complementary dealership oil changes don’t always spend the few minutes cleaning after themselves.
Could have come from another vehicle seeing as the lot is wet.
A/C condensation dripping and running down the pavement. Maybe?

Consensus is it’s oil, and it kind of looks that way; I’ve driven it 3km and nothing was wry, so I’ve parked it till Monday.
Check the oil level. If it’s fine, you can drive it back, over there. The oil pan plug uses a soft metal washer as a gasket. A previous car had one that didn’t seal right and my car was dripping ever so slowly. You can also stick a piece of cardboard under the car to try and pinpoint where the drip is coming from.
Hopefully a sloppy oil change and not a leak. Sloppy is bad, leak after oil service worse.
