It is an additive in the oil,some brands,and weights have more than others,(cheapo oils usually have the least,or none at all)...Get you some Rotella T6 oil, it has it in it,and won't harm your clutches...

That is why this site works so well whereas the rest are all drama,bullying,bickering over who has the biggest ego,and who can run their fingers the most..We all seem to care about the atvs,riding,and getting along with others while helping one another out instead of being smarta55e5 all the time,or giving non info like a kid begging for attention would...If we all keep helping one another out,and trying to help the newbies out then this place will be around for a very long time,and many people will learn to wrench on their own stuff instead of forking out ridiculous bucks to have some halfa55ed mechanic do a halfa55ed job which will have to be redone in a week,or a month...Keep up the good work Joey...

100% agreed!! i joined several different forums to begin with but this one is the only one that generally has an atmosphere of helping one another and offering factual advise, most of the time, without personal opinions unless they are from personal experiences about the topic at hand. i love this site and intend to do all i can to help it progress and provide helpful info to everyone.

Regarding the ZDDP question...

ZDDP is short for zinc dialkyldithiophosphates, which as DITB mentioned, help "cushion " the metal to metal contact inside engines - normally in bearings and races - but a major consideration in the Hondamatic's piston and cup's contact area. There's a lot of friction in this contact area, especially at low speed and heavy loads. You want all of the "cushion" you can get, and why you don't want thin or worn out and dirty oil.

As was mentioned, most diesel oils have high levels of ZDDP, but automotive oils have very little, because it plays havoc with the emissions system on modern gasoline automobiles.

In general, oils labeled for motorcycles have similar levels of ZDDP as diesel oils, but slightly lower levels of detergent.

One other thing to consider is the film stability, especially during cold starts. Synthetics are excellent in this area. I add Lucas Synthetic oil stabilizer to my non-syn 10W-40 4-stroke motorcycle oil to increase the film stability.

awesome info. what ratio do u mix your oil and stabilizer on a typical oil change? also, would u suggest adding ZDDP to this as well? if so, where can i find it?? after dodging the bullet with my transmission scare, i want all the protection i can get!! thanks.

I have to give another shoutout to joey for this awesome writeup; I find this kind of deep technical stuff to be as fascinating as heck.
