What Oil to Run - Synthetic or Regular?

Gray I noticed the Golden Spectro is on the AMSOIL list but not the Platinum Spectro(full synthetic) do you know how if it is better than the Golden Spectro? At my local shop the Platinum Spectro is $3 less per quart than AMSOIL. What would you advise?

I'd advise you to sign up as a preferred customer and pay less for the Amsoil.

But, if you download the current version of the white paper, Spectro Platinum is in it.

I don't know what oil you use, but by your posts, I'm going to guess Amsoil.

It really depends on what you consider "friction modifiers". The term isn't defined well in industry trade law. I am an Amsoil user, and preferred customer, and have been for quite some time. That does not change the fact that it contains high levels of zinc "anti-wear" compounds, and quite a bit of moly compounds for the same purpose. At one time, these were all considered friction reducers, and that is a fairly accurate description of one of the things a boundary lubricant accomplishes. But the oil does not contain these in concentrations regarded as high enough to qualify the oil as "energy conserving", so it isn't a "friction modified" oil, and they don't have to call it that. Besides, as was pointed out, no 40 wt will ever be rated EC II, anyway. This is one of those areas of the oil bidness where literal accuracy suffers a bit, unfortunately.

I'm sorry, too, but it's still ridiculous. The JASO standard, MA, and the later MA2, are oil standards that address primarily two issues: boundary lubrication and compatibility with wet clutches. Most contemporary motorcycle oils, including synthetics, are either certified MA/MA2, or labeled as meeting that standard, which specifically means that they are perfectly OK to use with clutch components made by Hinson or anyone else.

I use Honda oils in my crf 450

and I am a fan of Amsoil.Use it in my truck,and will use it in my yz as soon as i get it.

If your interested to see what oils are Jaso MA certified, here's where the list is found. http://www.jalos.or.jp/ on the left menu click the "jaso onfile" tab, then navigate through to the motorcycle list.

As you can see there are brands that submit for certification, other choose not too and simply state they meet or exceed the spec. (which may or may not) sometimes there is one portion of the test they wouldn't pass so will cite the standards they do pass by number. The consumer isn't complicated enough to know what the numbers mean so assume it's certified.

Just an FYI. Marketing is one thing, but misrepresenting a products ingredients or certifications, for example, is illegal. Two different concepts to keep in mind.

That's interesting...Thanks for pointing this out.

That's a pretty risky business proposition if you ask me. The consumer is being mislead and that ain't good. I hope they have the have some good legal counsel because a judge can request those products pulled from shelves real fast.

Amsoil plays that game. as do other specialty bottlers. In the car oils they claim api specs but don't submits for testing there either. Their XL line of oils have been cert. because commercial accounts have demanded it. the dirty little secret about the XL line, is it is not synthetic (it's group3) but they label it as so. Something they have criticized other company's for in their marketing.
