Comments On Apr 21, 2013:cant go wrong with Moly in the engine side, don't put in the clutch side though. And expect to burn a little as it is slippery and gets by the rings a little. And I would not use it for the initial break in, just to be sure those rings get seated properly

Comments On May 24, 2011:It does matter what you put in your engine. HP4 with moly is the best you can use for HONDA and its worth every penny if you want your engine to last longer.

Comments On Jun 02, 2009:Warning;
This oil says NOT for Centrifugal OR Automatic type
Clutches.
WHY: because it has Moly in it, that will cause slipping, and smoke the clucth plates.
So beware !!!
I was going to use it on my 2007 Honda Rancher.
Ill just use the GN4 oil instead.
Save the HP4M for my Honda lawn mower engine instead.

Comments On Mar 05, 2008:This is the only oil I have run in my 450 honda engine. I recently took my engine apart to build it up and was impressed with how new everything looked inside. It had lot's of hard hours on it and this oil did a great job keeping it all lubricated.
