I’ve noticed that my Infiniti M35 seemed a little bit sluggish on the throttle. Not really bad, but i tend to drive that car somewhat aggressively and just felt a bit of lag and uneven performance.
I figured I’d waste some money on a bottle of snake oil and bought a can of SeaFoam, and added it to a nearly empty tank. I took my daughter to day care, went to class and let it sit with a warm engine for an hour or so. After I gave it a good, old fashioned “italian tuneup”, driving hard for about half an hour on the freeway consuming the majority of the remaining fuel.
With the tank nearly empty, I then added another bottle of SeaFoam to thetank, and filled the tank with the same fuel I normally buy.
Surprisingly, it does seem to be more responsive and accelerates more smoothly. It also seems to be running smoother cold. I’m not a huge believer in the stuff, but it did seem to help in this case.
I’m curious if anyone would have any insight on what, if anything, the SeaFoam might have cleaned, and of it’s a false-flag and if the problem will return once the SeaFoam present in the tank has been consumed?
