fuel additives are best for high mileage worn engines? Well not really, as these engines will not be working very efficiently to begin with, and putting a small amount of liquid additive into the tank will do little to improve matters.Most additives claim to help remove built-up carbon and dirt deposits from the engine’s moving parts. However, independent evidence suggests most additives do not work and can actually reduce engine performance by up to 2 percent.The only way this type of additive would work fully is if you used it from when the car was brand new and continued all though its life. Again, the cost of this would add up and it would be cheaper simply to use a premium fuel instead.
