How many bottles of Chefu Fuel Additive should be added at one time?

[DiCayden]

For the first use of Chefu Fuel Additive, add 2 bottles. This depends on the fuel tank capacity and the instructions for the fuel additive. Typically, the initial use requires 2 bottles, followed by 1 bottle for subsequent uses. Below are the functions of the fuel additive: 1. Carbon deposits: Removes carbon deposits. 2. Atomization: Improves atomization. 3. Engine: Protects the engine. 4. Engine wear: Reduces engine wear. 5. Emissions: Eliminates black smoke and reduces emissions. Below are extended notes on precautions for using fuel additives: 1. Purchase: Pay attention to buying branded fuel additives; do not casually use those recommended by repair shops. 2. New cars: Do not rush to use fuel additives in new cars. 3. Driving habits: Do not rely solely on fuel additives to clean engine carbon deposits; pay attention to driving habits.

As a veteran driver with nearly twenty years of experience, I've used many brands of fuel additives. For the 'Chefoo' brand, I always add a whole bottle—the small 60ml size is perfect for one full tank of gas. Last week, I added a bottle to my old Toyota before refueling, just as the instructions recommend. If your car has a particularly large fuel tank, like a high-displacement SUV or pickup truck, you can add two bottles, but it's unnecessary for regular sedans. Remember to always add the fuel additive before refueling—pour it in first, then fill up with gas—to ensure better mixing. I recommend using it every 5,000 kilometers; this frequency is enough to clean carbon deposits without wasting money. Also, never add it when the tank is nearly empty, as the effectiveness will be greatly reduced.

I'm the type who really cherishes my car and always personally supervises every maintenance session. Regarding the dosage of Chefoo Fuel Additive, I noticed it's clearly stated on the bottle as 'one bottle per use'. Last week at the gas station, I specifically checked the packaging instructions - just pour the entire 60ml small bottle into the fuel tank. For my Honda Fit with its smaller tank, one bottle is sufficient; my neighbor's Highlander took two bottles, but that's a rare case. More importantly is the timing: add the fuel additive when the tank is nearly empty, then immediately fill up with gas. I typically use it once every six months, and always add a bottle before long trips to clean the fuel system. One final reminder: use up the entire bottle after opening, as leftovers can easily deteriorate.

Having driven for just two years, my main concern about fuel additives is whether they're cost-effective. I've done the math on this Car Mate product: a small bottle costs just over ten yuan, and using one whole bottle for a 40-60 liter fuel fill-up is just right. Last time during maintenance, the mechanic told me that using more is completely unnecessary and just a waste of money. Now, before each refueling, I unscrew the entire 60ml bottle and pour it into the empty fuel tank, then fill up with 95-octane gasoline. Using it every 5,000 kilometers works out to just an extra few dozen yuan per year, but it does save fuel. Remember not to be persuaded by gas station attendants to buy multiple bottles at once - unused bottles left in the car can deteriorate under high temperatures and sunlight.
