I understand that some of you may be using diesel oil in your bikes with some success. Just a heads up on using diesel oil in your bikes. Soon the only diesel oil that you can purchase will have the spec CJ-4 on it. This is the new spec for 07 diesels with the new emission equipment called particulate filters for the exhaust. This has a totally different additive package that has not been used up to this point and may not work as well with wet clutches as the older version diesel oils that some of you have been using. If you know of anyone using this new oil let us know how it is working out for them.

Is there something that you don't understand about the diesel oil post?

I've been around bikes for a long time, and I have never heard of anyone using diesel oil in their bikes. How about a little background on this use of diesel oil in crotch scooters.

We are not recommending the use of diesel oil in bikes, but merely advising those that are using it to beware of the new diesel oils that just came on the market. If you go to some of the other sites at the bottom of this website and do a search you will see many comments on this. I have been riding myself for over 40 years and have seen a lot of different concoctions used by bikers, so nothing surprises me.

I've heard alot of things about oil and " crotch scooters". I only use synthetic 4 stroke motorcycle oil for wet clutches. Can you use regular oil and work fine?

Some bikers seem to think so. I personally think that the clutch may be affected and also automotive oils are not designed for the sheering forces of the tranny like in a motorcycle. Some of the motorcycle specific oils also meet the GL-1 gearlube spec, which gives it more protection for the engine by keeping the foaming down, automotive oils do not. I think those that do some stunting should not push their luck with automotive oils as the clutch is one of the most important tools at a bikers disposal when pushing the envelope.

I fully understood it and figured it was SPAM...

And my name is Reverand Psycho Sick Balls.... but you can call me OSP.

What kind of oil are you running in your bike? If it is one that I haven't tested yet would you be interested in letting me take an oil sample? We both live in Orlando according to your profile.

H&D full syn... Possibly...

If you are using the syn3 harley oil then I don't need a sample since I have done some already and that oil shears back to a 40 weight, but it doesn't seem to hurt anything as far as wear protection goes. Also if you want to stick with a full synthetic bike oil then on your next change look us up and I will be able to save you a couple dollars a quart by using the Amsoil 20w 50. We have a couple of the dealers from our group that live in your same town.

Amsoil Dealer guy.. what about Rotella T Synthetic, You guys test that?

My bike asks for API SE, SF, SG SH, SJ, or SL

Rotella meets
# API CI-4 PLUS, CI-4, CH-4, CG-4, CF-4, CF
# API SL, SJ, SH

I have copied a few links that show some testing of rotella T against some other oils. The spec's that you pointed out for your bike do not include diesel oils, as the S (for spark ignition engines, gas) before each letter stands for gas engines. C's stand for compression ignition engines (diesels) but some of you do use it with no apparent damage.

But it meets the gasoline parts... Shouldn't that be enough?

If your owners manual only gives you those specs and makes no mention of JASO MA/MA-2 then the oil you are using is OK for your bike, but I think you might be over looking the part concerning these other specs which apply to wet clutch performance.

Hey all,

Oil debate goes on, on, on and on.

HDEO oil = Heavy Duty Engine Oil.

Like all other oils, you have good ones, bad ones, and great ones. Most of these HDEO oils are rated for gasoline engines. (Have never read a bottle that said desiel specific oil).

These oils are rated for use in you cummins, allison, detroit trannys (automatics).

These clutch plates require the same kind of lubrication as that of a motorcycle. These trannys are seriously abused behind 500+ horse turbocharged diesel engines, continuously slammed from forward to reverse.

I have asked this same question before and will ask again "Does any one have any proof of a clutch failure due to the use of a non motorcycle specific oil"?

You make some great points. I have seen slipping clutches with automotive type oils, but never one with a person using diesel oil. Now this might change with the new diesel oils (CJ-4) for 07 and newer diesels. These oils are using new additive packages with ashless additives to keep from plugging up the exhaust particulate filters. Don't know how this might affect wet clutches.

When they change to formula to the HDEO oils check and see if it is not still rated for the above mentioned trannys.

Check out a website called bobistheoilguy.com all sorts of UOA's from all name brands and weights of motoroils, both motorcycle specific and automotive. Some pretty good info here.

That should be simple to check out by taking a look at Shell Rotella T 15w 40 oil that meets CJ-4 specs. Let me know what you find out.

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.
