There is a release switch on the interior door panel; pressing it will open the fuel tank. Below are relevant details: 1. Definition of gasoline octane rating: The gasoline octane rating represents the fuel's resistance to knocking. For example, 95-octane gasoline contains approximately 95% isooctane and about 5% heptane. 2. Anti-knock properties: Since isooctane has better anti-knock properties compared to heptane, higher octane ratings indicate superior anti-knock performance. 3. Engine considerations: Whether to use 92 or 95-octane gasoline depends on the engine's operating temperature and pressure. Generally, naturally aspirated engines require 92-octane gasoline, while turbocharged engines typically need 95-octane gasoline.

















I find the fuel filler cap location of the C260L quite interesting. It usually doesn't have a dedicated button on the center console but is positioned at the lower left side inside the driver's door. To be precise, after sitting in the driver's seat, look towards the door side—there's a small lever or release handle near the bottom of the door panel and the edge of the seat. Using it is straightforward: first, park the car securely and unlock it, then gently pull the lever, and the fuel filler cap will pop open slightly. The advantage of this design is its direct and convenient operation, avoiding the clutter of extra buttons and reducing the risk of accidental activation. During daily driving, if you can't locate it, you can check the owner's manual or temporarily ask a mechanic—safety first, especially on highways. A small tip: regularly check the lever's flexibility during maintenance to prevent it from getting stuck and affecting refueling.

When it comes to the fuel tank button of the C260L, I often get asked by friends. Actually, it's right within reach when you're driving, located on the inner side of the door next to the driver's left leg. Position-wise, it's somewhat like a small handle—just pull it after unlocking the car to open the fuel tank cap, simple and straightforward. I find this arrangement quite user-friendly, unlike other cars where you have to search all over the center console for the button, making it hassle-free. When refueling, remember to close the cap tightly before driving off to avoid any issues from road bumps. Also, for safety reasons, don’t let children play around with that area, as driving involves fundamental safety concerns. During maintenance, pay extra attention to dust accumulation to prevent the lever from getting stuck.

The operation of the fuel tank cap on the C260L is straightforward. Located inside the driver's door at the lower left, there's a lever. Simply unlock the vehicle and gently pull the lever to open the cap, with no need to search for additional buttons. The exact position is by your leg when seated in the driver's seat, making it very convenient to use.

I was deeply impressed by the fuel tank cap issue when driving my C260L. The release lever is located on the inner side below the driver's door. Every time before refueling, I'd park the car, unlock it, and just pull the lever - it opens effortlessly. Remember to operate it steadily, don't rush to avoid forgetting to close the cap. Safety first.

Many people mistakenly believe that the C260L has a dedicated fuel tank button, but it typically features a lever inside the door. The lever is located on the lower part of the driver's side door frame. To use it, gently pull the lever after unlocking the car to open the fuel tank. This design is simple and reliable, reducing clutter on the center console. Remember to check that the fuel cap is securely closed after refueling to prevent it from popping open while driving—safety first. During maintenance, ensure the surrounding area is kept clean.
