I'm using amsoil 10w 40 and have had good luck. I have done two oil changes now and getting ready for 3 and I think it helped quite things down some.
I've been holding off with my first oil change on the beast but I'm saying screw it. I'm not believing it's the oil that caused problems there just isn't evidence supporting it. It's been awhile since clutch issues. I've always ran t6 in everything with very good luck. I'll be switching this weekend. I'd say wish me luck but I'm over it. I'll talk more with my warrentee guy tomorrow and get the whole skinny he said no on synthetic because of the clutch issues but I'm just not buying it. I've heard two people say Honda didn't seem bothered by syn. We have too many machines to take care of for one to be different. Even the Rekluse in my bike requires Rotella and that's a specialized auto clutch. It's time.
I was unsure prior to my first change and did a good bit of research. I ended up using HP4S at first fluid change, Honda's synthetic... I used it due to it being rated by Honda specifically for wet clutches. It meets all requirements per the manual and Honda. It didn't make too big of a difference in noise-- if any-- as I was intentionally being mentally aware of a possible placebo effect, but Mobil 1 4T 10w40 in the sub trans and RP 75-140 in the diff's 100 miles later did make a difference in terms of quieting the unit down. I believe the RP made the biggest difference in minimizing gear whine.
I asked my dealer about using Amsoil 0w40 when I picked up my machine and he said no problem, he seemed to be familiar with the oil. I am interested in the use of Rotella t6 as I've used it for years in my diesel trucks and tractor, have it on hand and its a lot cheaper than Amsoil, but I have the Amsoil on hand too so I think I'll go with that for awhile. Did you mention Rotella t6 to your dealer? I can understand his reluctance if he was not familier with the diesel oil use in wet clutches.
From my understanding, if you provide the JASO and MA ratings required by Honda to run in these units to your dealer, they cannot deny anything warranty related as you followed the owner's manual and Honda's requirements. I know HP4S follows every guideline as well as is recommended for this unit on their Honda oil website. The one they will not cover is the Syn they make with moly added to it as it specifically states do not use in wet clutch systems.
No he said any syn. I've had very good luck with t6 and I know I'll get flack for using it but it's not just "diesel oil" it's got lots of good additives but most importantly for us it's available anywhere. Until the p1k we used it in everything it makes it so much easier as I do maintenance for others up camping and even if I didn't believe in it it's still fresh oil and things get changed more frequently if we use it. Last weekend alone I went almost 200 miles and haven't done first change. I should have switched then. But enough about Rotella I just would like to know in general. My warrentee writer,lead mechanic,and salesman said any high grade non-syn oil was ok. Is that true??? They told you different, other people? Was I lied too?
No problem, I am just going by Honda's guidance. I don't personally pretend to know for sure what a dealer will or will not do, nor what Honda would do -- I just simply follow what they recommend and hope if I have an issue they will honor what is said in their manual and on their Honda Pro Oil website.@500 you're on top of it thanks again
I need oil change bad this weekend so I'll be all over them today! I hate having the wrong information!! I've been thinking about it for awhile and syn isn't taking out clutches it's obvious
I use it in everything including my rotaries with zero issues.
Me too. Off topic but rotaries are the only thing I haven't played with. A buddy years back had a 79 rx with twin 13b turbos it was so much fun. Rated 565 rear tire with a 13k redline. Kicked the crap out of my 426 wedge Mopar always been impressed!
