As a rule, excessive fuel consumption is caused by wear of the cylinder-piston group. After revitalization the geometry of the parts is restored, and fuel consumption returns to normal. In addition, a lower friction factor (surface roughness 0.06 Ra instead of the usual 0.9 to 2.1 Ra) significantly reduces friction losses. As a result you can save up to 30 % of fuel at idle and 5-7% of fuel when driving.
