Delo 400 is made by Chevron.
Recent word around the campfire in the forum circles I frequent(both bikes and cars) is that even Rotella T has had the zinc levels significantly cut recently and Mobil 1 red cap has had reduced zinc for some time now. Mobil Delvac and Castrol Tection still seem to be good choices that are available at most parts stores. (There are at least 100 less common diesel-spec oil brands, many of which are suitable for bikes)
Somthing that should also be considered when choosing a wet clutch oil is how much molybdenum is in it. Moly will collect on the fiber plates and make the clutch slip. Delo 400 seems to have above average moly content as far as diesel spec oils are concerned.
anyone using Shell Rotella T in their old Honda?
Honda added HP4M with molebdynum disulfide as a friction modifier to there oil line up to bond with top end parts right about the time some V4 owners started discovering a bit of a problem with top end oiling.
After the advent of serious sportbike production the rumour started circulating that the moly could cause slippage on these high performance clutches. In 13 years I have yet to actually witness this occurance either at the parts counter or through the service department. There are a lot of different additives on the market with wildly varying claims and it can get quite confusing when trying to decide on what is right for your particular application. So I thought it might help some of you dispel some myths and clear the air a little bit if you read this: http://www.ford-trucks.com/article/idx/ ... ative.html It certainly opened my eyes a bit! Although they don't discuss moly in particular, they do provide a bit of insight to the ways of the industry that might change the way you think about what your putting in your precious motor!
Is it simply a long-standing rumor with no credible evidence, or is it based in fact? Has it been completely proven, disproven, or does it cause problems sporadically on a case-by-case basis? I'm not trying to grill you; just curious because 'd like to get my facts straight and make sure I don't spread potential rumors in the future.

I have not found a VERIFIABLE source for the rumour, that is, a case where NO OTHER cause for slippage could be proven, and an excessive molebdynum disulfide deposition proven. There may well be a lab out there with the hard cold facts of it, but apparantly they're not talking, due to "proprietary reasons" no doubt. That's one of the things I like about the article, they really went at it with a Missouri attitude. Talk all ya want, but ya ain't sold me til' ya show me the proof!
There is a little exception that you have to think about here, now. We don't have to worry much about particulate solids clogging our filters, no sir, unlike modern bikes we have centrifugal oil filters. Which means that any additive in our oil is not getting past our filter unless it's lighter than oil! This whole thing could be a moot point, as our fancy oil is gradually being purified back into plain old oil as we unwittingly motor our way down to pickup another quart of that brand x stuff that we swear by. I'll stick to breaking in fresh motors with Spectro 4 and a splash of Marvel Mystery oil to the top end, and Spectro Golden (synthetic blend) afterwards. Hasn't let me down yet. I guess the only lessons here are the same old ones that we forget everytime we hear about something new. Hey, we want to believe it if we think we'll benefit in some way, that's how they always take us in. Caveat emptor. Buyer beware. Read the fine print. If it sounds to good to be true, it probably is. DO YOUR HOMEWORK! I'll tell ya what, though, if you really want to save on gas, I've got this magnetic crystal pyramid that you put in your gas tank..........
Yes I agree with you. It is a very interesting website and tells the truth . Buyer beware and snake oil does not work and you can't prove me wrong. You are right about the centrifugal oil filters, they get a coating of all kinds of stuff. I used to use Castrol oil and always had a thin film of some gray stuff in the filter. Keep up the thread, are slipping clutches a myth or not.

I figured that's what it would boil down to. It probably doesn't work as well as my micro x-ray emitting oil additive reactivator crankcase drain plug!
