 Location: Stones throw away...finally!!
 | I was told last weekend that you should use full synthetic (green) for your main motor.  They said you could get away with the blend (yellow) for your kicker.  The only reason it came up in conversation is I didn't realize that there was a difference until I went to change my lube recently, and noticed that the lube I bought was different than what was in there.  This is just what I was told.  The full synthetic holds up better in larger engines.  Any truth to this? |
