mine was make a click sound from the engine the frist time i change oil i add someER to the oil help the clicking soundhelp a little. So on the next oil change i use ER and prolong in the polaris oil click soud is gone by 90% or better formula is 2oz of ER and half bottle of prolong mix with 2qts of polaris oil and shake well fill atv to oil level and in joy the piece and quietness of the engine

 

May sound like a stupid question but what is ER...I have never heard of it. Please let me know what it is and where can I get it.

 

ER is energy release it's a oil addtive like prolong. it only seem to work with both, tried each on there own, but work the best with both
