I have read most of the info on TCW-3 oils on this site. I have been using Yamalube 2M in my new 2005 90 2S. I am paying about $17 a gallon and this hurts to pay that. So I am going to switch to a cheaper brand.<br /><br />My question is whether or not the different oils will work together? I think I read somewhere on this site that mixing them caused them to combine and glob up.<br /><br />Does this matter?<br /><br /><br />Searun1
