Hi! There are many injector cleaning fluids available at our service stations. In fact Toyota too have their own such fluid. Do any of you guys have any experience with the use of these fuel additives? Is it any good? And most importantly will regular and proper use of these cleaners prevent manual injector cleaning?
The reason for my query is that my Hilux (brand new Thailand model) has done around 138,000 k.m. Since of late it has developed a vibration on early morning start ups and an odd clatter from the engine as well. It gets back to normal running once the proper running temp is reached. It reached a rather alarming level this morning hence, I spoke to Toyota Lanka. They seemed pretty sure my injectors were blocked. It seems that it has come to a level that the injectors have to removed and the cleaning carried out the old fashioned way. The manual advise the use of their cleaning fluid initially at 75,000 k.m and every 45,000 k.m afterwards. I used it initially around 115,000 k.m. So it clearly has gone way past the manufacturer's recommendation. I most importantly it hasn't worked (for me at least).
Also a word of advice for fellow owners with cars with common rail diesel engines. It is advised that the best place for any work in relation to the engine be carried out by the respective agents as many owners have learned a bitter lesson after work has been carried out else where.
Hope to see some constructive comments. Cheers guys!
P.S : Any idea how much it costs to get the injectors cleaned at T Lanka?
