Is this a good additive to use to clean my fuel-injected V6? Thanks for any advice. ...I guess the other alternative is engine dis-assembly? I have over 100,000 & all of it but maybe 1000 isnt mine.Dont know when the injectors were ever cleaned,but my 99 Galant GTZ 3.0 V6 'seems' to be running fine.But I figure whatever can be done to get every bit of gas mileage I can out of it these days,would be a good thing
