Evening gentlemen

I recently purchased a 2013 LS460 and am loving it. Such a smooth ride and everything else. One thing I noticed was that there was slight vibration at idle and would go away in neutral. I can feel the vibration from steering wheel. Out of curiosity, I went ahead and grabbed a bottle of techron fuel system cleaner at chevron and have my car took a shot. The vibration was still there after couple hundred miles of driving or until the tank went empty. I grabbed another bottle on the next fill. The second tank is almost going empty and now, the vibration is gone, or I can hardly feel the vibration. With the music on(not loud), it feels like the engine is off. My car has 61000 and I'm wondering if techron really works reducing engine vibrations?

 

Not that i have heard of. It is a slight issue for many LS's . Did you turn on your seat warmer/cooler button recently?? Keeping something on like that will cause the rpm's to stay just above 500 and will keep the vibration away at idle.

 

Does your rpm gauge bounce a little when your stopped at a light? Ppl claim it works for all kinds of things. If your feeling the vibration at idle and not in neutral that just means that the issue lies with the engine and not the transmission since they are disconnected when in neutral and connected when in drive. I've used a combination of Techron, Seafoam and Berrymans B-12 over the years and At times I felt that they all worked but never felt that they made my engine run better. I used them mainly to try to keep the valves and cylinders clean and it makes ME feel better in that regard but I have no proof that they do that either.

 

i use the Super Tech Motor Treatment, 16 Fl. Oz from walmart for $4 it make the 460 feel great
