Have two different opiions from two different Toyota dealers on this very subject. Darwin dealer use an additive, not sure what type, never asked me to use it on my vehicle and charged me $20 (got that refunded). Went to another dealer on holidays in Tassie (Devonport) asked him about the additive, he said it makes the new engine noisy. Clears too much crap out through the injectors etc. Not completly sure of full details! Just thought it was interesting! Have to say my engine is noisy at times, sounds like a 50c coin bouncing around under the bonnet....
