Just thought I would post about my experience with using acetone in my diesel. Its now coming upto 234K miles on the odo and have been using it since 126K miles. Its a 2000yr (X) 1.7dti with the only mods being the air box cones removed.
Some repairs have been carried out but absolutley no fueling issues have arisen at all. So over 100K miles and its proved to me that it doesnt damage the engine in the slightest.
Anyone else using it? What have you found out? Any problems?........G
