Have ditched DP and now using CEM. Double dose of decarboniser for two full tanks and using CEM's diesel additive as well. Tapping "may" be slightly less.... but overall rattle is definitely quieter. Motor seems to idle slightly better (smoother) and I note that the "pulsing" I was getting in 6th at 100 km/h under light load is now gone.... no idea what caused it, but do know that after each dose of Toyota injector cleaner - that pulsing seemed to go away again after the tankful went through it. CEM seems to improve almost everything.... I have nearly 5 litres of DP left over if anyone wants it - won't be going back to it. frats, Rosco

Thanks KAA

Same here, 164k owned since new.. all oil/filter changes well within recommended. Diesel Power added in exacting amounts every tank, BP Ultimate fuel used almost exclusively - if not, premium diesel... and only twice - standard truck diesel. Toyota fuel injector cleaner added every 20,000 km's. Currently up north with 2.5 tonne van. Had injector values read at St. George.... technician reported them all "within spec"... and told me there was nothing to worry about - "normal diesel fuel knock". Was not offered written injector values.... Had motor tested again Charters Towers... "all within spec" - highest was 1.2, lowest -0.8. Again told "normal".... rattle/tapping noise is not "loud"... and no louder when cold.... but can be "just" heard over wind noise with all windows up at 100 km/h towing van. Seems more apparent at a scan gauge l/100 km readout of between 12 & 17 l/100.... seems to be quieter under heavier load.... no noise coasting (ruling out mechanical constant noise). Watching this thread with interest.... frats, Rosco

Hi folk, thanks for admitting me to the forum. I have two Toyota's... a VDJ200R 2011 LC Silver Pearl Altitude (from new) and an RT104 1977 Corona CS sedan (second owner since 1990). frats, Rosco
