Yes, Rislone is compatible with both conventional green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) antifreeze.
We recommend you drive/idle vehicle for 15 to 30 minutes. In most cases the leak will be sealed within this amount of time. If the leak is not sealed, a second application maybe required.
No, the sealing particles will pass through the tiniest passages inside of the cooling system. Note: If using Rislone to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core.

Rislone is only designed to be added to the cooling system. If the product is installed in the gas tank, the tank should be removed and cleaned out by a professional mechanic.
Rislone is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine apart to clean all of the parts.
