No. It will affect your emissions and you may not pass the emissions test but it will not affect fuel economy.

Wasting too much gas: You need to change spark plugs and leads. Do NOT gap the plugs. Install them right out of the box. If you gap them, you will ruin the platinum coating and you'll be right back where you started.

Also, put a can of Restore® in your oil, it heals the scratches in the cylinder walls. Get it at Wal*Mart, NAPA or AutoZone.

I would personally say you have sludge in your engine, depends on mileage and how you drive it. Of course I don't own a Focus. Again more reason to seek a professional.
