I run mobil one in every four stroke i own even the lawn mower. I extend the drain time between the oil changes and have had very good luck with it. The only thing i would be careful of 0w-20 sounds too light for the rx/apex. As i remember the apex's manual calls for 0w-30 thats just off the top of my head i would double check. Many would say that the synthetic oil is a waste of money but when you are out in the middle of nowhere its really good piece of mind spending a few extra bucks on the good oil. Just my 2c. I put a quart of dino oil and a quart of mobil one in the frezzer over night and the next day took them out and poured a little out of each the mobil one poured much faster than the dino oil. What this ment to me was oil gets through the engine faster at startup on a cold day and thats a good thing. I thought i might warn you that wifes dont like to find motor oil in the freezer. Do that at your own risk. I forgot what the dino oil brand was but it was a cheap one like walmart or something along the same lines.

I have see in is signature in the pass that Rockerdan use 5w-20,I put amsoil 0w40 in my sled this year so i can't tell if i like it or not.I have always use mobil1 5w30 in all my car and never ad a engine failure.My Honda recommend to put 5w20,but i will try amsoil 5w30 this year.Automotive company push the 0w20 for fuel economy. Other than that i don't see much advantage.

Don't use 20 wt. in a trail sled. 20 would be ok in a stock dragsled only! 40 wt. will rob power!!! Stick with 30 for your trail machine.

Do you think 40 would rob power in a dry sump system? If it did it would be very minimal I would think as it (the crank) is not sloshing around in and through the oil like a wet sump.

I've used redline 5-20 or royal purple 5-20 oil in 2RX1'S and my Apex GT and have never had any problem starting in the extreme cold or using oil.Maybe I am crazy but the thinner oil seems to give the engine better throttle response too.

see..this was my thoughts exactly...but the yamaha service manager at the novi show said not to run any synthetic due to the wet clutch starter!
I know some ams is ok for wet clutch...will check on mobil one...

I agree

I don't know if I would run 0-20.
Us Amsoil dealers got a memo a few years ago when they introduced the the new oil as an alternative selection for Honda and Ford's requirement.
These oils were needed to meet the demands of the tighter clearances of a few models that were engineered to get low emmissions. I thicker viscosity was not recommended by Amsoil, and I think it was said that the manufacturer's would void the engine warranty if a thicker oil was used.

Amsoil warned us dealers about using this oil or selling this oil to customers with "conventional" engines, for the lack of high heat-breakdown protection from the thin oil. Low film strength, if I remember correctly.

If there are any other dealers who remember this, please correct me if I'm wrong.
This memo was from 3-4 years ago.
