Maybe you meant MCV AND ARO?

AMV was replaced by ARO which was replaced by MCV. Neither AMV or ARO or offered any longer

FWIW Amsoil 20w50 MCV is probably the highest viscosity motorcycle 20w50 oil on the market. It's viscosity rating at 100'c is even higher than Redline 20w50 by about 5%. What that means to you is it will protect your engine very well and has a fairly large margin for shearing before it shears out of grade. I don't sell or use it but just happened to be looking at the data between Mobil1 Vtwin, Redline & Amsoil today and was surprised by the data.

They don't play the false chart use game.

All the charts in the world are useless...the only way you can really tell is with used oil analysis (UAO) or virgin oil anaylsis (VOA).

Used oil analysis is an excellent measure of the remaining life in an oil however, it is autonomous to the particular engine. Depends on the mechanical condition of that particular engine and how it has been treated.

Charts are another good measure of an oil provided they use the Industry Standard test methodology which is the ASTM Standard. If that Standard is used it means that anyone using that standard can reproduce the same results and it is the only test data recognized by the Automotive Industry. The standards are available on the web.

If the test isn't according to ASTM Standards and performed by an independent Laboratory, it is purely Subjective. Not many companies publish ASTM test results other than AMSOIL. As a side note. We have over the road Tractors that have a million miles on the pan oil changing filters every 20 K and using used oil analysis using AMSOIL Diesel Oils.

Boy, what did we do  back when all we did was, change oil and ride? At what point in time did we all obsess about what oil to use and how long before changes?. all the internet did on this subject was give people more useless oil information then anyone needs. if anyone had a real problem with oils, and motors were blowing left and right, it might be of value. But thats not the case. I doub't anyone has blown their motor due to brand of oil or wether it was dino or synthetic with normal changes by the book. but people want the best for their "forever" kept bikes ,that are the first thing that gets sold when times get hard. look on ebay at the pitifull milage people put on their bikes in 5 or ten years. these are the guys that worry the most about which oil is best to use. only to sell their prized possesion for a fracrtion of what they paid for it. I'll bet you don't worry about what goes in your car when you take it to quickey lube. And you'll use it harder and keep it longer. todays oils are better then oil's were 10 years ago so use whats called for and don't waste your time worrying what brand is the best.,,,

At the point when the EPA started mandating emissions specs on air cooled motorcycle engines. If you study oil technology you will se the difference between automotive oil and motorcycle oils and it is only getting worse as time goes on. 20 years ago there were no prohibited additives in oil for automobiles and no fuel injected Harleys. Today's air cooled engine is probably the harshest place for a motor oil to run. How many water cooled engines run at 220-300F? ( dino oil starts cooking off it's additives at 250F) How many use oil jets to cool the pistons and are set extremely lean to meet emission standards and still have huge tolerances and higher compression ratings. Same reason you don't see air cooled VW bugs or Porsche 911's being sold here anymore. Today's Harley TC engine is not like the old ones. I wish it were.

Comparing you car engine to an air cooled motorcycle engine is ridiculous. If you don't believe me go get a 260F thermostat installed in your car and see how long it runs. BTW your automatic trans will melt at 250F.

I don't own an automatic transmission so melting isn't a worry I have. and I'll stand by what I've said in the other post. this obsession with brand and manufacturers specs is more then anyone needs to know. use the right weight and go with it. the Harley motor is a glorified lawnmower motor whose final days are comming near.there are guys that run the factory oil and others use the cheapest 20/ 50 they can get, and run the motors for years with no problems. so their motors only last 30 years instead of 40 years. I haven't seen any proof useing $10 a qt oil helps your motor last any longer just alot of opinions.,,

I'm with you Big K. I have never seen such fussing over friggin oil. Just change once in a while and run the piss out of it. You'd think these guys were running a jet engine. This engine is just a simple air-cooled 4 stroke. See that the new ones breathe better, get more petrol and run-em!!!

I think the big C is right to a point, but all the same I think I'll look into getting the right stuff in the right hole. It gets pretty hot here in Fla.

Back to the original question, the biggest difference is the absence of friction modifiers in the motorcycle oils, which allows them to be used in wet clutch applicaton.  The ARO and other engine oils have them.  The motorcycle oils are also designed for the harsher environment of a cycle engine..heat resistance and oxidative breakdown.
