What is the recommended mileage to replace a 1999 Chevy Suburban fuel filter?

There's no single "recommended" mileage for replacing a 1999 Chevy Suburban fuel filter. The owner's manual is the best source, but generally, it's recommended to replace it every 12,000 to 15,000 miles, or at least once a year, whichever comes first. However, several factors can influence this:

* Fuel quality: If you consistently use lower-quality fuel, you might need to replace it more often.

* Driving conditions: Lots of stop-and-go driving can put more stress on the filter.

* Vehicle's age: As the vehicle ages, the filter may become more prone to clogging.

Ignoring a clogged fuel filter can lead to engine damage, so it's better to err on the side of caution and replace it sooner rather than later if you suspect a problem (poor acceleration, rough running). Inspecting it during other maintenance might also reveal if it's dirty and needs replacing.
