This experience really shook me and left me
It was my tested and trusted 03 Accord. There's nothing I didn't think of!

Will be updating and getting to the culprit in subsequent posts...

I woke and started the Accord. Got out of the car to round up a few things. When I got back, there was an offensive odour from the tail pipe. I couldn't also tell if what looked like steam from the exhaust was mixed with greish smoke.

I decided to give it a little gas...to confirm.

It was a sad discovery.

The smoke ranged greyish to bluish while I had my foot on the gas. When I let off, it became an effortless plume of bluish smoke with the horrible smell.

I was numb. When, how, from where?

I know I have an oil leak from the mating area of the oil pan. Could the oil have gone so low that the engine wore?
A family member had been using the car for the prior 4 days. I began to run permutations...

I checked the dipstick, it was low. However, I was parked on an incline, so measurement won't be accurate anyway. Also, I didn't have a CEL. On this Honda, you should get a CEL from oil starvation of the VTEC solenoid when the oil goes low.

It was the suddenness that baffled me the most. Could the engine actually be worn? Maybe I've been puffing bluish smoke gently without noticing?

The culprit... Google is your friend

I took to the Web. Turns out that certain fuel system cleaners can cause bluish/greyish smoke as well as strong odours when used. Especially in the morning.

It was then it clicked. I added the Gumout product below to my tank some days earlier...

The product has Gumout's CarbonClear proprietary tech which has PEA as well as 2 other cleaning agents.

I am still on the tank of Gumout fuel, but the smoke has now totally stopped. The smell is gone too.

It's said that the smoke shows the product is working

I forgot to mention that the water that usually drips from the exhaust now turned black.
This is explained by the carbon being cleared from the engine.

The water is no longer black too

Just in case you want the blue smoke experience
I have a few bottles to spare which I can sell. I'll open a thread in Autos.
