Hey all

I noticed my car was starting to blow a bit of smoke since my last oil change. I used a 10w40 synthetic and i think it might be too thin.
So i topped it off with 20w50 and it didnt seem too bad at all.

(Im running a Smallport 16v 4age)

Anyhow I got pulled over today and defected by the cops for blowing too much smoke. #$@!$#@!~@!
I think they were trying to get me for anything.. measuring my height, pulled me up on the color, exhaust ... everything.

anyways..

Questions:

A) Whats the best thing to stop this ? Can I use Nulon Stop Spoke additive or are they bad for your engine? Has anyone successfully stopped smoking with this kind of thing?
Is there anything Better than Nulon stop smoke?
Should i do an oil change before putting it in?

B) Assuming it is Piston ring wear.. how bad can that be for an engine? Does performance deteriorate with worn rings?
Should I stop red lining it ? Do I need an rebuild or can the engine live on with worn piston rings? I thought 4ages were tough.

Any advice would be good.

thanks
