Ok I'm here at my dealership mm Kwai its bobby js so anyways I'm doing a oil change Ana they said that if u were to bring them to get service they would use 20/50 oil in the summer and 10/40 in winter now what do u guys think ? I can't find 15/40 anywhere

I think you are probably just fine with 20/50 in the summer and 10/40 in the winter. Go for it! I couldn't find 15/40 either. I went with 10/40 for my first oil change. Besides, I trust the guys at Bobby J's.

The CFMOTO oil is 15/40. But I certainly can't really disagree with the dealers answers either!!  

I get 15w-40 at Walmart. I would go with the Rotella t6. Good oil and not expensive. I usually switch to it after a couple break in oil changes.

Castrol 10 40 in the engine with a K&N Filter. Valvoline synthetic on the gears.  When you change the oil be advised that the funnel and hose they give you will not fit in the fill hole.  Also make sure you clean around the fill real good to avoid knocking dirt and mud into the crankcase.

My dealer didn't give me one of those funnel-n-hoses. Had to make my own. Yeah..not a fan of where the filler/dip stick is located.

Check your glovebox, that is where my funnel and hose was.  I had to cut the end of the hose on a 45 to get it in.  I might tape on a funnel end like I seen someone else do here .

What ever brand you guys use, be sure it is certified for a wet clutch. Car oil is not. It has friction reducers that can cause the wet clutch to slip too much.

I did start off using 10w40 Motul 4T 5100. The only reason was because i thought I had read it was the "official" oil for CFMoto, but I couldnt find anything after the fact that claimed this. It also has a distinct smell that i liked.

I'm thinking on switching to 15w40 Shell Rotella. Nothing beats a premium diesel oil. The anti-wear additives they put in it is a good idea considering they dont use traditional ball bearings on the crankshaft, the valve guides are non-serviceable, and the camshafts too do not use traditional ball bearings.

I started using diesel oil in my jeep as well because of the anti-wear additives including the zinc, which my old 4.2L engine was designed to have in its oil, something only found in 15w40 now.

K&N oil filter?  Do you have a part # and source for that?

I don't think you want any K&N filter. I won't trust even their oil filter after this. Here's a post on why:  http://cfmoto-forum.com/800ex800/warning-about-kn-air-filters/

If you want to risk your machine, use K&N oil filter KN152.

Other Options include:
HiFlo: HF152
Fram: 6104

do you need special oil for the wet clutch or  regular 15/40 motor oil

Until we get a better handle on it just use a good conventional with the proper rating as outlined in the manual. Historically, unless specifically designed to operate with synthetics, friction devices need a conventional oil or one designed for their operation. There is a Castrol synthetic that says it can be used for wet clutches however we have not tried it...yet  

I am about to do my first oil change.  It seems like recommendations for oil are all over the map.  I ordered a couple of the HF152 filters and am trying to decide on oil to use.

A couple posts up someone recommended just using conventional oil for the first couple changes.  So its not critical to get wet-clutch compliant oil?  (for a CF800).

Also, I am North Florida, so I am not too worried about sub-freezing winter weather.

How much do I need?  seems like motorcycle oil is sold in gallons.

Says in my Z800 manual it takes 2900 milliliters with the filter which is 3.06 quarts. So get a gallon. Next time get three quarts. You can use motorcycle oil either 10/40 or 15/40. Just to be safe, use conventional. I'm using Castrol. Just make sure it has an SG or higher API rating.

The 800s do have a wet clutch so it is critical that you get an oil designed for wet clutch use...

I personally use a 15w40 diesel grade oil (Shell Rotella ) because of all the anti-wear agents and Zinc thats in those oils. I'm not a fan of the "bearings" they use in these motors so I go with a high quality diesel oil to help prevent premature wear. Also, the shoe packs in these arent the best and tend to wear quick. I'm in the process of working with STM Powersports whos making a wet clutch delete kit.

How has this oil been for you since you last posted on this?

What type of oil are the rest of you guys running?
