Is BG44K good to use for a 1999 Maxima SE? If not, can anyone recommend a fuel additive? Thanks.

 

I've had good results with fuel injector cleaners, the kind you put in the gas tank. I recommend it where there is a clear indication of an injector problem. I don't recommend it for use as a preventive measure.

IMHO all name-brand fuel injector cleaners are equally good at cleaning injectors. Techron claims to also clean carbon deposits from the stems of intake valves. Certain engines -- older four cylinder Toyotas in particular -- have this problem. I've never heard of it in the VQ30DE engine used in our 4Gen Maximas. For this reason I would not pay the higher cost for Techron.
