I have a 2015 Carrera with about 20k miles. Bright it to my garage and had the mechanics look at it. Nothing wrong with engine, they scoped it said everything looked fine but I’m slightly burning oil 1 quart every 2k miles and no leaks or smoke. What else car I look at to solve the problem?

How does the serpentine belt look? I think it’s due for replacement every 6 years so it may be worth a look to see if it worn as well as the idler pully(s).

Welcome. 1 qt/2k miles is not horrible but it’s not great either. What service have you had performed? Plugs, air filters? Last oil change was with what oil? You can get your next oil sample tested at Blackstone to see what that looks like.

This car is new to me, 6 months of ownership and I’m treating it like a car with 40k miles. I’m looking for things to change or at least look at so this is a good start.

i question what type of oil my regular garage in August. I’m going to have it done again with my Porsche mechanic.

This has been driving me nuts because there is a faint smell but nothing major.

Do an oil analysis.

Do a cylinder compression test and look for bore scoring.

1 qt every 2k miles is high. Normal would be 1-2 bars (0.1-0.2 qt) between every oil change.


and your car is NA as well, huummmmmm

1qt oil / 2K miles that crazy.

Did the car actually give you the red warning notice about low oil or how did you calculate?

How long have you had the car?

BTW the car smelling "hot" after driving is normal. If the car doesn't smell hot especially in a garage after driving you're not driving hard enough.

Just to add: I'm at 122,xxx miles and never had to add a drop of oil. If it makes any difference I do change oil every 5,000 miles.

I’ve noticed that after driving my C2S hard in sport mode it has a burnt rubber odor after parking. No oil burn with mine and just changed it with Motul 5-40 and the belt was changed 3k miles ago so you can count them out. I’d do a fresh oil change with good grade oil and check your plugs for oil deposits, plug #1 usual scoring culprit.

Did you ever find out what the burned rubber smell was?

My guess is that is the Porsche approved fragrance. These cars have a smell, especially when driven hard.

For the OP, 1Q every 2K miles is a lot! Per suggestion above, get it checked out.

When I bring it home after a good spirited drive, my wife takes a whiff and says “ Smells like you had fun.”

It smells like....victory.

I’ve changed the oil and the plugs, and it still has the “victory” odor. Based on other comments it’s a good thing.

Plug 1, pic not so clear, has some carbon deposit, car obviously needs some track time 😉

As others said, there are two separate things going on.

The burning smell is normal for these cars, but the amount of oil burning is borderline Not OK. If you go to the dealer they will tell you burning that much oil is within thresholds, but I would be concerned.

First thing I would do is an oil analysis followed by bore scoring check. (foil analysis comes back with conceding numbers)

Good luck

This post relates to the burnt rubber odor aka victory smell. Agree on the loss of oil and believe the OP addressed it already since there were no posts back.
