Has anyone used this to stop your engine from smoking? if so did it help?

No I do not believe it will stop engine from smoking though if valve seals are worn and rings worn it may help I use it as it keeps lifter quiet!!

Does rislone high mileage formula engine treatment have zink zddp in it is it safe for catalyctic converters

It is safe for your catalytic converter but they have another product that has the Zinc which is the Rislone Hy-per Lube ZDDP Supplement

Is this safe to use at every oil change

I've used this as an additive ever since I hit 75,000 miles and I do the oil change every 3,500 miles there after.

How do you add it into crank case?

Thank you for your question, and for considering Rislone to help with your automotive needs. To add this product to your engine's crankcase, you would install it into the same opening where you would add engine oil. Do not overfill.
