Understanding Black Smoke on a Ford Fiesta ST 150
When a Ford Fiesta ST 150 emits black smoke, it can be a cause for concern. Here’s what the black smoke might indicate:
1. Initial Black Smoke at Start-up:
– If your car emits a little black smoke at start-up, but it clears up as the engine warms to operating temperature, it’s considered normal for some cars. However, if it continues after the car warms up, there may be cause for concern.
2. Over Fueling:
– Black smoke can be an indication of over fueling. As standard, the ST’s run rich (too much fuel) as a safer option, as opposed to running lean (too little fuel).
3. Potential Causes:
– Overfilling the oil can lead to black smoke when revved, indicating a possible relation between overfilled oil and black smoke emission.
4. Action Taken:
– If you notice black smoke, it’s advisable to address the issue promptly. In some cases, draining excess oil and taking the car for a drive may help alleviate the black smoke emission.
It’s important to monitor the emission of black smoke and take appropriate action if it persists, as it may indicate underlying issues that require attention.
