I just put a new top end in after 300+ hrs, only ran Motorex in engine. Cylinder walls still had crosshatches in it. Compression was still great,only changed piston cause of the hours. HIGHLY recommend Motorex. Its the only oil I will use!Read All Reviews

2006 yz125 50:1 with 46.7 hours on top end running strong pulled it apart at 40 hours and it had very low carbon build up and was well lubricated nice film on piston and cylinder sleeve honestly think I could get away with 60:1 pricey but worth it! Try it out!Read All Reviews
