1994 Geo Prizm Motor Silk

Hello,

I could not resist the temptation to buy MotorSilk and add it to the crankcase after changing oil. I hope it will increase mileage a little, protect the engine and most importantly stop the slight vibration I feel on the steering wheel and even sitting on the seat.

It has not helped with the vibration issue so far.

I had the front struts/strut mounts replaced a few months ago and had an alignment done on the car. (Not for this problem) No change.

What can be the reason for the vibration I feel on the steering wheel, on the dashboard and even on the front seat?
