Here's a breakdown:
* Clear to light yellow: This is typical of high-quality diesel fuel.
* Dark yellow to amber: This can indicate a higher sulfur content, but it's still within the acceptable range.
* Red or purple: This usually indicates a dye added to identify it as off-road diesel fuel, which is taxed differently.
* Cloudy or hazy: This could signal contamination or water in the fuel.
Important: The color of diesel fuel doesn't always accurately reflect its quality. It's essential to use fuel from reputable sources and check for any visible contaminants or unusual smells.
