Be wary of using some automotive oils as there are a few that contain Moly. IIRC, there are warnings in the Honda owner's manuals about using engine oils with Moly as it can cause the wet clutch to wear prematurely. Trust me, it has happened plenty of times, not just on Gixxer,com, but with many many people with several different brands of M/C. Sometimes the best oil really is an OEM motorcycle oil, synthetic or dyno. IMO, price be damned.

Do your oil research properly, and you'll come out ahead.

I've done well with Royal Purple Max-cycle and a K & N filter on my ZRX.

Here is the best INDEPENDENT oil analysis research done outside of a oil manufacturer/retailer grasp. It's for aircooled Porsche and Volkswagen engines, but many of the areas covered apply to motorcycles as well. Charles of L.N. Engineering can even do an oil analysis for your personal use motorcycle/car.

Moly designed properly for it's specific application does not always cause clutch problems if it meets the wet clutch specs. For example Honda's motorcycle oils do contain moly, as well as other motorcycel oils. Go figure.

Good stuff... I use Rotella 15w40 no problems I understand an read about the CJ-4 and heard guys using it with no problems also
Take a look at some post on the www.600rr.net site. There is two reports of clutch problems using the new diesel oils, but that doesn't mean anything yet as they may have had worn clutches getting ready to go.

Links? I failed to find the posts you mentioned. Anecdotal information should be taken with a very large grain of salt. I'm curious to know how they determined that the clutch was slipping.

It doesn't take a brain surgeon to know when their clutch is slipping. If they don't notice it at first they will certainly know it in time when they can't get off the line. As far as the diesel oil and clutch slipping issues that I alluded to when I get more time I will find the post and will give you the link.

Diesel oil in bikes

Hi,
Very few riders use diesel in their bikes to make the bike perform good and show the excellence in the race and the diesel provides the bike with very well lubrication and pick up.

Vash,
Either Robin knows just enough English to order a cup of coffie or he knows even less about motor oils and motorcycles. He might also be pulling our leg by writing something that makes absolutely no sense. It is kind of funny.

oil

Guys,
Can't we beat this tired thread to death again? To mrAmsoil NOT all ofHonda oils contail the moly the Do offer one without....Having run Ams oil myself its no better than the mtorcycle specific oils out there and if a person is councious enough about their bikes to change he oil more frequently conventional is no worse than anythin else out there....the additive concerning motorcycle specific oils I believe was phosporus....Further if one is concerned there are labsthat wil analyse your oil to find out what type of wear your motor is incurring.....Also if you take out your motorcycle owner manual and check what oil is reccomended for temperature and viscosity index for your temps ost oild will do whether 10-30,10-40,20-50.....I do know from personal use of the mobil 1 exclusively in a 1979 GS850G from 1983 to date.....it runs cooler...not that in the summer its a cool motor to ride....and when I do a valve adjustment and its done yearly....I seldome have to change out valve shims and the internals under the valve covers look fresh and almost without wear.....this bike gets a change every 6 months whether it needs it or not......and still gets about 50 mpg to this day and is within 10% of OEM compression still....The key whether you use or what you use is the interval do it when it needs it and they will last...and as an aside this bike has never shown any clutch slip over the many years....

I think I'll take this one away from George as 90% of my business is Motorcycle.

Yes, Honda offers the oil both ways, with and without Moly. As stated Moly can be used in a Motorcycle oil.

The talk here is about Diesel oils and there have been some concerns as Diesel oils that have been reformulated. You cannot run the same oil made in 2006 in a 2007 and newer diesel. Period... There are several differences.

IF.... IF the oil carries an SG/SH Rating, it is safe to use in your bike.. Now, try and find an SG/SH Rated oil for an Gas or Diesel engine.

The API Ratings for oils Do Not Automatically Supercede. Meaning that if your bike calls for an SG/SH oil, SL or SM is not OK.. UNLESS it carries the SG/SH...

As far as ZDDP... Mobil 1 still has a higher amount than many oils but the Automotive M-1 EP is no longer a PAO based synthetic. Gas Chromatograph shows it is now a Hydro-Cracked oil.

Also, there are a building number of cases where they may or may not have a clutch problem with M-1 Auto, but in many cases, the problem arises when going to another brand oil. Clutch slippage and/or clutch chatter. Now, M-1 Racing 4T is a very good oil and is different than any of the M-1 Auto oils.

I always say:

Regardless of Brand, Synthetic or Petroleum, I always recommend a Motorcycle Specific oil with a JASO Rating of MA, better yet, MA 2, but Never MB.

Reasonable results can be had with a good petroleum oil and a good filter.. Superior results can be had using a Premium Synthetic and a Premium Filter.

If anyone tells you that there is No difference between an Auto/Diesel oil and a Motorcycle Specific oil, they have been greatly misinformed.

I'm not one to really throw down hard on the throttle, but I just recently changed to Rotella T 5W 40 synthetic and my bike shifts 100% easier and smoother than before. 1998 Bandit 1200

Guys,
The JASO designation is sort of new as far as oil specs go.....whether you run a specific oil or not isn't worth a hill of beans if you change it frequently enough....do I feel like spending all that extra cash on private label brands or name brand oils is well a moot point....it gets to running an oil within the viscosity range for the environment you are in.....diesel oil, car oil its all four stroke oil.....all the mfg gots their oils labeled but who makes it and is it worth more than a qt of wtfever oil you want to run......I got no dog in this hunt and I'm not trying to sell anything...if you good fells from Amsoil are sponsors I surely don't mean to offend but the majority of riders that are concious enough to get into one of these threads prolly already services his or her bike like it needs...I do, have for over 30 years......what ever I ride.....
thats why I can still ride and enjoy a 1979 model Suzi.....how I manage to get great mileage from a 1300cc Sport tourer, how my cruiser just runs and runs......Its all about that and if somebody wants to run private brand label
oils thats cool but if you dont and runa conventional ol and service it more frequently ...you aren't doing harm either......Awwww hell lets go for a ride...now whichbike do I want to ride

I really hate it when people post in old threads, but I think this is the most appropriate place for some new information.

Shell's Rotella T6 5W40 synthetic oil and Rotella T 15W40 conventional oil are now both JASO MA certified, i.e., approved for use in motorcycles with wet clutches. This should put to rest the debate on whether it's safe to use these excellent diesel oils in bikes.

Oddly, the T5 synthetic blend is not certified. I would guess they didn't bother to test it.

Cool update, thanks.

Its always been my preference to post in older, directly-related threads rather than creating new ones. Makes finding my info so much easier later.

The thing is that the Rotella you have used in the past, is not the Rotella of today. Shell changed the formulation around Sept of '09.

Also, it is not JASO "Certified" . It has not been tested. Shell, as some other oils, use the JASO qualification from their additive suppliers to become "Self Rated".

Wow thats really interesting. Thnx for sharing!
QUOTE]

Welcome.

Where oils use to change every 4-6 years in the past to keep up with new technology and engine designs, it can now be every 4-6 months in some cases.

That is one of the reasons I am against doing "Searches" on forums. New things can come about quickly and the information will not come to the surface.
