it doesnt do anything to your octan contain to my knowledge, its a cleaner that dissolves dirt.Kevin Hoare said:What does it do to your octane rating? Do you have to be careful when it's in the tank?
The real bk44 is most likely only availible though either dealerships or service shops. It's not something you can really do at home. You tap into the fuel rail, unplug the fuel pump, block off the return line and the cleaner is put into a pressurized tank(by shop air-compressor) and the car is ran off the cleaner only. It usally runs for around 20 mins or so. The toyota stuff comes in it's own pressurized canister, but you still need the right fittings to do it. I think we charge an hour labor(70.00?haven't checked for awhile) and the price of the cleaner.(appox.40.00) Short of removing the injectors and sending them off-this is the only way to really clean them. I don't have much faith in the type you poor in the tank-it gets so dilluted and mixed I don't see how it can be that great. It might clean out your lines and filter, but then you might have "sludgy" gas going into your injectors that may harm them in the long run(just a theory) The bk44 does however also include a can to pour in the tank as well. I have had much success with the bk44-i think it does a better job than the toyota brand stuff. I run it though my mk3 about every other third or fourth oil change. As far as fouling plugs-I have never seen in myself but if I were running the cleaner and installing plugs at the same time-I would do the cleaner first and than the plugs. I would give it a shot if you have the cash-call around-most dealerships can do this. I always recommend this whenever someone brings up this topic.-hope this helps............supra178 said:toypro, where can you get a can of bk44? what is your experence? please share with us. thanks.
