4age Gas smell
In general:

white smoke -> water
black smoke -> oil or gas

If white smoke lasts for 5-10 seconds, most possibly water is condensing somewhere. Are you driving your 4AGE hard ? Happens on various engines.
Black smoke can be various things. Oil or gas, bad piston sealing (pistons, rings, valve stems...) OR to much fuel (various reasons).

4age Gas smell
I also have sometimes gas smell inside my AE86, i guess it's due to two holes on the trunk floor (maybe the car was GPL some time ago) and the smell goes in by those, although they are sealed!

About the smoke... i got no smoke.... and my oil consumption is sometimes big... depends on the type of driving i'm taking....

The white smoke i get sometimes it's water on the muffler caused by night's humidities....

Trying the Castrol 10W-40 for now and see if it goes well! Respect!

when the car accelerated the gas smell increases, does not waste oil, gasoline is closed to the maximum for the inspection.

no smell of burning oil, just a bad combustion.
