You can get carbon build up with lower octane which will eventually cause power loss. Wrong--use the octane recommended by the manufacturer. Use of a higher than required octane can cause carbon buildup. Most of the carbon buildup will be on the backs of the intake valves, and that comes with any grade. Use a product made to clean things--AMSOIL PI or BG 44K are the best I know Dick in Falls Church, vA 85 Saab 900 turbo
