i've been wiping off the small amount of power steering fluid from the boot(passenger) every time i do an oil change, and topping off my ps resvivor. (1-2mm drop off from hot max)
I thought about getting a stop leak for my power steering..

what is the best brand for me to use, that won't affect anything long term.
i've heard lucas does damages.. not positive on this

 

Don't.

Try flushing the entire system with new fluid. If it continues replace the rack.

Stop leak will kill the pump and rack over time.

So deal with the leak or replace the rack or use stop leak and replace the rack and pump later.
