What can cause an earlier change in oil color in Corolla 1993 (4AFE engine. Fuel injection, made in Japan).?

I have Toyota corolla 1993 with 4AFE engine. Apparently there is no problem with the engine, but I see that color of the engine oil is turning dark very soon. I can also see black powder in the engine exhaust. I don’t feel any oilishness in this powder. The engine oil level however slightly reduces in a month time. My engine looks good as it is still throwing water from the exhaust however I feel that compare to before engine sound and idle speed is increased a little bit. What could be reason for change in oil color? Can worn-out engine valve seals cause change in oil color? Any ideas?

I’ve been looking and looking for an engine made to run on Hydrogen gas…?

And hopefully specifications on its fuel consumption vs it’s horse power. And then of course pricing.

Has anyone seen the commercial for a new fuel made from water, does anyone know what the website is called?

I saw a commercial for a gas that allows you to get 2,000 miles per tank. It was supposed to be made from water and I cannot remember the website. It was something like gasadvance.com, but that is not a valid web address. Thank-you anybody that can tell me something.
