Aston Martin MY13 from 98 octane to 95
I accidentally mixed the fuel tank in my car, I always refuel it with 98 Octane. but today I accidentally used 95 Octane. since I have two cars. So I went home and switched off my car. but when I switched on later after 30 min I got the "Emission System Service Required" Message, yellow hazard, check engine 'yellow and Nav got erased.

Coincidence, according to book of words she can handle 95 Octane. It is detected by the knock sensors and the spark advance will be less, so you'll have less power.
I was forced to get 95 Oct. (nothing better a the only petrolstation around, the good stuff sold out) and I had no problems at all.

95 Oct. did not bring up any messages and I filled 60 liters of the 95 stuff. So my guess would be pure coincidence, the V8 has 4 knock sensors and adjusts spark automatically. I am not 100% sure about knock sensors on early V12s (they have none), there you might get protest messages.

But as mentioned earlier, the car can adapt to lower octanes.

Let's pretend I don't know what RON or MON are. Can you give me a brief explanation. I always figured gas was gas the world round and why did Europe get the good stuff.

https://en.wikipedia.org/wiki/Octane...rement_methods
Research Octane Number (RON)
The most common type of octane rating worldwide is the Research Octane Number (RON). RON is determined by running the fuel in a test engine with a variable compression ratio under controlled conditions, and comparing the results with those for mixtures of iso-octane and n-heptane.
Motor Octane Number (MON)
Another type of octane rating, called Motor Octane Number (MON), is determined at 900 rpm engine speed instead of the 600 rpm for RON.[1] MON testing uses a similar test engine to that used in RON testing, but with a preheated fuel mixture, higher engine speed, and variable ignition timing to further stress the fuel's knock resistance. Depending on the composition of the fuel, the MON of a modern pump gasoline will be about 8 to 12 octane lower than the RON, but there is no direct link between RON and MON. Pump gasoline specifications typically require both a minimum RON and a minimum MON.
Anti-Knock Index (AKI) or (R+M)/2
In most countries, including Australia, New Zealand and all of those in Europe,[citation needed] the "headline" octane rating shown on the pump is the RON, but in Canada, the United States, Brazil, and some other countries, the headline number is the average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2. It may also sometimes be called the Posted Octane Number (PON).

Great news guys, today I rolled my car and the check engine is off, plus the Nav setting is back to normal!. it happened when my fuel indication was in half. Thank you guys for the support I really appreciate it. I've never been a car guy no I am inexperienced.
