The dipstick is where you fill it.

 

Wow,ok,thx. The drain bolts were super hard to get to The holes in the skid plate didn't match up with the location of them had you stuff a funnel in between which got most of the oil. I hope everything's not this easy to work on.

 

So ppl just vac the oil out of the dipstick to save on the mess. Other make the rear skid plate removable. So try all type of different funnels.

 

get a Curtis valve

 

sheesh i paid alot of money for this thing, just thought they it would be a bit more refined in the simple stuff. my old Cfmoto was easier to do an oil change and the had a better manual too. metal removable fasteners on the skid plate ,STOCK

 

X3's are super easy to work on. Anybody who says otherwise has never worked on something difficult. I read dozens of posts online like yours where people complained about changing the oil before I did mine, I was amazed at how wrong they all were. A cheap silicone funnel is really the only "specific" tool you need.

 

Buy a MavR and then change the tranny fluid. First time I spent more time cleaning the car and the garage than the oil change.
Curtis valve is the way on an X3.

 

Your X3 has been sold to the public for nearly a DECADE. It’s not like there is a lack of information out there regarding these types of things. It just takes a little research on YOUR part. Welcome!

 

After the oil change and after taking the 1st drive where I could let loose and open her up,I'm hooked. put it to the floor and launch. i think id like to race,not to get the best time,but to go as fast as i want without responsible me always more concerned about someone coming the other direction.

Yes, it's a challenge the first time. You have two good options moving forward: either pump the oil out of the dipstick port or get a Curtis Valve. Either option provides a fast and easy oil change. I use an old-fashioned metal funnel that gives me about 24" of length to get the 3.7 quarts back in.

Curtis Valve: (replaces your Oil drain plug, watch a YT video on how to do it)

 

After I figured up how derpy I was being, I added the Curtis valve in the right spot, in front of your tire, not the rear diff, and it makes total sense.
After I did everything including the "drain mode" I was able to get 3.7qts. Take it from me and I did everything wrong, but once I figured it out, I can see how the Youtube videos only take the oil change 10 mins instead of two evenings. I haven't done my next oil change yet, but I put the hose on and it should be a no muss no fuss deal.
There are folks on here that have it down, but the 24" flex funnel is a must, I bought a 18" but got things done.
Curtis an aircraft company and the valve is high quality and I do have faith in it.

Listen to the others and take advantage of their years of knowledge.

Just my 2 cents
