I posted this question once, I think ??? Not sure , so here goes again.
Scenario is as follows:
Took my girlfriend's 96' Mustang ( 6 cyl. ) in for an oil change yesterday. We are on a 500 mile trip, so I decided to add a fuel conditioner to the gas ( Nu Energy, Fuel Injection Cleaner ) in a 3/4 tank of gas. The fuel conditioner was good for up to 20 gallons. My tank would have had 7 - 8 gallons.
About 75 miles into our trip I notice smoke coming from the from the exhaust when I accelerated and then backed off the gas.
I then decided to get Chevron 91 octane fuel when the tank was about 1/4 full.
This did not change anything ..... it continued to smoke when going up steep grades or after acceleration.
The car seems to running fine, but the amount of smoke coming from the exhaust worries me a great deal as this has never been a problem before.
Does anyone have any idea what is happening here ???
Really appreciate any input as we are on a trip and are concerned.
Thanks,
JC

Don't recall the post before and I read posts. I doubt this is the cause and now it's diluted. Hate it when stuff happens away from home like that but it's worth keeping a sharp eye on things. This should be checked and try to deterime what the smoke is. Black smoke is usually rich on fuel, white can be normal for a while when cold, white can be burning engine coolant usually thru a leaking head gasket, blue is oil burning and in some cars vacuum controls to an automatic trans if equipped can seep ATF into intake manifold. Check all fluids and suspect the one(s) if any that are low.
You might detect some oilyness with a clean white cloth in tip of tailpipe. Some carbon would be there normally.
The good sign is it's running well for now. Carry extra oil and coolant if you are worried for this trip and use your judgment as to attempt to get something here fixed now but that's tough on weekends as you would expect.
If it was caused by super cleaning of the fuel system it should quit it soon as more gas is used and that product diluted yet again.
You have to decide based on how well it's running and if you think it's odd enough to get it looked at now. Any smoke out exhaust can be very hard on cat converters so it would be nice to end this as soon as practical to save them. Watch the gauges assertively and decide for yourself what to do about it for now,
