My 200 has over 115k kms on it and I switched to full synthetic at 105k once my service contract was over with the dealers. I've had a vibration that can be felt throughout the body, steering wheel and pedals (felt at standstill not while driving). I always brushed it aside as I had an aftermarket exhaust on and thought that caused the vibration but after putting the stock muffler back on the vibration is still there. Asking around I was told it was normal and a characteristic of the engine, Anyone know if the 4.6 in the Tundra do the same and/or the US 5.7?
