2011, 30K, can run at 80 on the interstate and when I push it to the carpet, some gray smoke comes out very briefly like it is running too rich. Never noticed until a friend behind me told me. Ok or what needs correcting? Runs great,zero oil usage, usually I drive very sanely but now and then I just feel like letting her go up to about 135 from 70 which does NOT take long!!
Guidance,opinions,thoughts?

 

No suggestions?No thoughts?

 

You say that gray smoke comes out very briefly. That is maybe not a cause for concern. But if the gray smoke is not that briefly as you say then maybe you should visit a mechanic.

 

Thank you for the response!! My bud behind me said it smelled like raw fuel everso briefly.

 

You went to a mechanic?

 

Two bottles of TECHRON FUEL SYSTEM CLEANER in consecutive fillups seemed to have done it.

 

Oh, nice. Glad it's nothing serious.
