I purchased a used 570s , paid for pre purchase inspection and everything. The mechanics didn't even bother checking the oil level for me. When i got the vehicle home i check the oil level it was on red too low. I added 2.3 litres of oil exactly to get it to the highest green tick.

With 2.3 litres missing has the engine been damage or am i still safe. 2.3L is alot of oil when thinking about . I couldn't stop thinking for the past few days, that i might have made a big mistake purchasing this 570s with oil too low running around for unknown periods of time. Can someone enlighten me if i am safe or i have made a big mistake.

I assume these high end McLaren come with low oil warning but apparently i found out the 570s does not. The previous owner never checked the oil level between oil change , otherwise would never sell it with oil level on too low.

Lesson learned never assume these expenses cars to have a low oil warning and assume the pre purchase inspection will check the oil level for you. I brought it to a high end shop that specializes in exotic cars too, not just any average shop. They still over look the simple oil level check just like i did too.

Relax boss, get some oil in it and drive it slowly till you do. Its just too low, the engine hasn't been starved yet. It probably had even more oil since it is reading too low right now. The car drinks oil loke crazy like check it every week.

Why would it have more oil since if its was reading too low?
Doesn't the reading reads the level of oil in the reserve tank.
If it was missing 1 litres i wouldn't be concerning but 2.3 liters or 2.5 quartz thats alot.

Does anyone know how much oil much does the oil reservoir tank even hold and whats the safety oil threshold.
I originally add 1L and it was still to low and then another 1L it got to mid green tick. Then another .3L to get to the highest green tick. There's no oil leak i had an inspection. Drove it for a week now still hold at the highest green level.
probably the previous owner never top up since oil change. Or who ever change the oil didn't leave enough reserve oil to burn between oil change.

The manuals says from too low to full is 1L so this car probably went 1L beyond too low. According to the manual it burns 1L for every 10k km.

The dry sump system complicates this. It is documented in the owner's manual.

"High end" doesn't mean that they know anything about McLarens, as they have demonstrated.

What have they said?
Did you call them immediately upon seeing the issue?
Did you document (with photos) the oil level?
When, and where, was it last serviced?

When you have an inspection, you are placing a lot of trust in the mechanic. It is imperative to have someone that knows the particular model look at it, otherwise you're just paying for generic checks, which anyone can do. I suspect that, unless the car fails quickly, you're going to have to put this down to experience.

Sorry for the confusion. It is always advisable to check the car's oil every week or every two weeks depending on the frequency and harshness of the drives. I had my 720 topped up in march but it read too low in about 1.5k miles of street driving (i decided to check randomly one day). But the cars arent actually crazy with the the oil(my apologies again) i just want you to never get top end engine wear.

I posted the a page from the 570 owners manual. It says that when only 1 bar of the segments is full the car is too low and needs 1 liter of oil. The fact that it is reading at all is perhaps a good sign. You said, the car was driven previously to you checking the oil level (specifically in regards to the picture you posted containing the low oil level). When you were driving before checking the oil and if you were driving it hard (touching the redline), a car's engine then may suffer some abnormal wear (think revving a cold engine hard). When i said the engine oil was probably higher before if you would have been kind enough to understand what im saying youd see that i was merely trying to assure you that there naturally had to be a bit more oil than the amount you have in present in the case you were driving the car hard before, unbeknownst to the threat. I checked the 720s manual for you as well. In the 570 owners manual (refer to my first post) when only one bar is full, it says 1 liter of oil is required, the 720s system reads oil level a little differently and requires 0.9 literes at the same point..when my 720 was at the red and too low (i checked randomly after thousands of miles) my dealer said it is fine and just to not hit the redline, they also said the fact that it was reading the oil level was a good sign and the car probably had enough oil when i was driving the car the weeks before..upon closer inspection, all was well but i always check my oil every week. 570 readings again may be different, i just kept my 570 for a couple of months so i dont have the real ownership experience. Mclaren engine oil readings are weird and are easier to overfill than just fill up completely. When you do an oil change you add the first chunk of oil and theres no differemce but the last 1 litre is just about what the car reads on the dash (can someone confirm this is something to do with the dry sump system? Perhaps the reservoir?), this makes it very easy to overfill. Overfill is not your issue, the omission in your pre purchase inspection is indeed unacceptable, but idk what id do if i were you really. 570 (along with otbers) consumes 1litre of oil per 1000km and may consume even more when newer. So it may have read in tbe green just 1.5k to 2k kms ago, but thats for you to figure out given youve been driving it

I have never noticed any oil consumption in my 12C (and I do check). My 928GTS does - 1L every 500 miles is not uncommon. If I had that in a newer car, I would be concerned. More, i.e. 1L per 1000km, and I'd be getting rid of it.

Thanks for spotting that! i did the quart to liter conversion wrong. 0.1 liter per 1000km, 1 liter per 10,000km. OP, your ppi was BAD

They were actually specialize in McLaren, i was very disappointed in them.
What can i do now, the car runs normal, I had confronted them immediately , they said they only check the oil level if i had them do an oil change. Bs excuse
The service history was pretty much unknown, car only had 20k km on it.
That's why i brought to a McLaren specialist.

Sorry, but if they didn't check the oil level, they aren't even a competent garage, let alone a specialist one. Did they give you a report, with or without a checklist?

Other than having it documented that the oil was low, and not checked as part of the inspection, I doubt that there's much that you can do now. However, I would have it serviced, and have the oil that comes out analysed.

Good idea , I'll probably just get the oil sample analysis. There was no oil check list or other check list . they just list a bunch of thing they found that needs to be taken care of like Tire wear ,missing underbody tray ect.... Hopefully someone can learn from my mistake.

I have run into this issue with my 570s. And the car has visited the dealer twice to address this to make sure there is nothing wrong with my car, and there wasn't. Long story short here is what was told to me from McLaren Scottsdale.

1. The motors are hand built, and especially being a turbo'd car some motors may consume more oil than others.
2. Driving style depends on oil consumption, if you are flooring it a lot, then car is going to go through oil quicker.
3. If oil level gets into the red, just add 1-2 quarts as soon as possible, not the end of the world don't worry.

Bottom line is, no car is going to be the same. Some Mclarens never go through any oil, some go through it more than others. Just because your car may burn through oil faster than others doesn't mean something is wrong with it. I drive my car pretty darn hard so I check my oil level often and usually have to add a quart here and there. Do make sure if you haven't already, look for leaks. But don't worry about getting your oil level in the red 1 time. If you were doing that often then it may be a concern, but go add 1-2 quarts and you should be good to go!

Being low on oil is obviously not ideal, yet keep in mind this is a dry sump system which holds 9 liters so you still had 6.7 remaining. The shop that overlooked checking the oil is not worthy of your business.

Note: Edited post to reflect the oil capacity according to the owners manual.

Low oil not a problem. No oil is. Car telling you to just add some. As long as there was enough oil to lubricate the engine all ok.
Not sure but would expect engine management to stop or give a severe warning if oil level critical??

I don't know of anything related to oil quantity, but I would expect there would be safeguards for low oil pressure.
