MSG I sent to the AMSOIL tech department

I have a 2008 Suzuki Hayabusa and I have a few questions about different oils in Amsoil line up. I know that Amsoil offers some motorcycle specific oils but I want to know what other oils Amsoil offer that do not have friction modifiers added. HDEO are widely used in shared sump bikes with no clutch problems. Is Amsoil HEDO FM free? I am a member of bobistheoilguy.com and questions like this come up often. Is it possible to provide a list of oils that are FM free? If not, here are a few that I am interested in.

European Car Formula 5W-40 full saps

DOMINATOR 10W-30 & 15w-50 Racing Oil. (Has FM)

Z-ROD 10W-30 Synthetic Motor Oil

Heavy-Duty Diesel and Marine Motor OilSAE 15W- 40

Series 3000 SAE 5W-30 Synthetic Heavy Duty Diesel Oil

Thanks

When I spoke to the Amsoil engineers regarding oil for our gixxer 1000 and 600 track bikes I wanted to use Dominater but the motorcycle oil was better for my application.

The 20W-50 is stout stuff, Sunrah tested it and had noting negative to say.

I switched from Rotella 15-40 to Amsoil 20-50 motorcycle oil to help the shearing problem in my Shadow 1100. It helped that problem and as an added bonus after 500 miles the clutch grabs much firmer now. The clutch feels totally different - it engages much faster with no slipping. I now believe there is a strong case for using a motorcycle specific oil. I don't think there is anything wrong with the Rotella, I just believe the Amsoil is better. Roger

i wouldnt say amsoil is "better" as a blanket statement.
if you compare price...those 500 more miles came at a big cost.
some on here (mkilroy is 1) think SRT makes for a grabby clutch and dont like it. so your weak/slipping clutch with SRT seems opposite of most.
not all oils work in all bikes, but SRT has a long record of working in most.

kjack, use the amsoils with confidence. just be sure to wear your parachute on that rocket!

I would think that while Amsoil HDEO's don't have friction modifiers, they also might have less anti-foam additive than their motorcycle specific MCF and MCV oils? That's the main reason I lean toward motorcycle specific oils is a focus on foam resistance is (or should) be one of the objectives when they formulated the oil. HTHS is a bit higher on their 10W40 (MCF) than their 15W40 and 5W40 HDEO. Also read on here that while both their HDEO and motorcycle specific oils are PAO/Ester blends, the motorcycle formulations have a higher ratio of Ester to PAO than the HDEO's. Something to consider for off-season down time since Ester's polarity should allow a little more oil to stay on the metal during periods of non-use? It was in a post a few yrs old, however, so it is possible the blend ratios could have changed with formulation changes since then.
