IMO its good to clean every 30K - 40K. it increase the fuel consumption and remove the sludge's from engine and i have notice the engine sound gets better.
That's a fabulous shot!however be cautious when you go into these muddy waters , because there is every potential that the catalytic converter be damaged.

im also bit curious about this as i heard only thing catalytic converter be damaged is by using leaded petrol - according to EURO standards EURO 3 + is recommended for catalytic converter fitted vehicles. where what happens is the led will distry to platinum layer on the catalytic converter which will be useless after that.
