i will be using after market additive tomorrow to clean my injectors. was wondering does it make ne difference if i use optimax or normal ULP. yes i havw use search. did not answer question. also is mobil injector cleaner ne good. nefing ppl recommend

All the bottle injector cleaners would do the same thing,
they're just solvents + detergents.

How effective they are is open to debate but will never be as good as
an off-car injector ultrasonic cleaning (=$$$).
But probably worthwhile as a preventative effort.

I have bought just about every brand out there, from no names to big names.
Can't say I've found much difference; usually buy Wynns, STP or Valvoline (when 2-4-1).

i used one once the nextday my fule gauge dident work just goes straigt to empty even with a full tank:rant:
