Since it's my first time doing an oil change. Do you have to jack up the car to do the service?

Personal preference, you have enough room to do the oil change without raising the vehicle and safely securing it on JACK STANDS, or good quality and in condition RAMPS, but its on the tight side.

I change the oil in my Commander (3.7L) with it just parked on level ground, and I'm a lot bigger than the average guy. Makes it tougher to get under it, but I have longer arms to reach. It is a bit of stretch and you do have to lay on the ground to do it.

BTW, people do kill themselves all the time getting under a vehicle that is just supported by a floor jack or tire changing jack, secure it properly. I had a guy kill himself a couple blocks from me, changing oil using the tire changing jack.

The Commander has less ground clearance than other Jeeps, my '95 Cherokee (XK), its a total waste of time raising the vehicle for an oil change, there is more than enough room.

Ditto what Mongo said, better to be safe than sorry. If there is enough room why add the hazard?

Thanks all. I 'll give it a try this weekend without jacking it up. I know I can easly remove the oil filter. I don't know where the hell the oil plug is. I took a quick look the other day and figured it was somewhere under one of the openings in the skid plate.

.... one of the reasons I miss my silverado that had 8" of lift and 37" tires... I was able to sit under that thing with a chair to do my fluid changes! :lol:

I do my oil changes and tire rotation at the same time... so I Jack my whole vehicle up and support it with 4 (3ton each) Jack stands. While the oil is draining I rotate the tires and inspect the brakes/bushing/joints/etc/etc. For some added safety I throw the Jack under one of the crossmembers near where I'm working.... figure is something odd like a minor earthquake hits and shakes the vehicle off the stands ill be a bit safer with the Jack next to me (I know... no earthquakes in NJ... just an example )

Edit: correction, I use the 6-ton Jack stands. They have a wider base and are taller... the 3-ton ones are tiny and don't give me a very secure feeling when "extended" to get the vehicle off the ground. Only need to go up 3-4 notches on the 6 ton ones.

Well I just finished my oil change and found no need to jack up the jeep. The oil filter has very easy access - removing and replacing. The drain plug through the skid plate was also easy to access. I did make a little mess on my driveway but will pickup some driveway cleaner at Home Depot. From start to finish took a half hour. Much better than dropping off at the dealership and waiting the whole day.

My 98 XJ I could just get right under the Jeep, no raising necessary. As someone else said, the Commander has less room underneath so I put it up on ramps and chock the back wheels.

I think I'm going to invest in one of those drain plug/valves because the first couple of times I did it, I didn't take off the plastic skid plate, oil everywhere out the back. The most recent time I took the skid plate off and broke one of the bolts getting it off. It was on ridiculously tight. I'd rather not have to take the plate off every time, but I don't want to make a mess with the skid plate on.

I did look at the Fumoto but to tell you the truth I just dont trust it. I'm sure it's well designed and works fine but I would rather have a plug.

I agree with you, although it would have to be extremely rare that it would get hit by something to knock it off, it could happen.

Yep, it does have advantages, I don't fault anyone that does want to use it, but personally I'll just stick to my old fasioned plug, I have lots of rags to wipe up the bits of oil that get spilled.

I had one of those valves on one of my vehicles. My one issue with them is the relatively slow/steady flow rate. My personal, non verified, non backed up with any data or lab tests opinion is that I "like" that quick/initial rush of fluid when you first pull the drain plug. It will evacuate particles/sediment/debris that's at the bottom of the pan better. However, whether that actually matters is questionable..... and yes that's what the oil filter is for... so I know both sides of the discussion. After the dust settles, my preference is a standard drain plug $.02.

With a fropnt skid plate, the FUMOTO valve is hard to operate.
There is a dealer here that uses a valve to suck the oil out. He says it
gets more gunk out of the engine that way.

Anyway, with the front skid plate on, oil changes are more difficult.

Huh? Ever take an oil pan off a motor? Guess how much gunk is sitting on the bottom that can be vacuumed out by the drain hole? About zero.

Of course, if an owner wasn't taking care of their engine and NOT changing the oil often enough with good quality oil, maybe some sludge would collect on the bottom that a vacuum could suck out, BUT I haven't seen it. Granted I haven't pulled the pan off an abused motor, except maybe worn out 440, with broken rings, etc. but even that was the same, its even coat of stubborn sludge on the surface, that has to be scrubbed off with a rag, maybe even some solvent.

Granted, I can't see how it could hurt, I also can't see why they need a valve to do this, where does that come in?

I think he just means they use a fluid evacuator to suck the oil out through the dipstick access.... You put a hose down through where the dipstick is and suck the oil out.

I do this to for the trans before I drop the pan... makes the job A LOT easier. Some shops have gone to this method for oil changes too which prevents possible drain plug damage/cross threading. It doesn't really get more or less gunk out... just makes it easier for the mechanic :rofl:

Yea, I thought he might have meant that, and I would guess also, no real advantage or disadvantage, just personal preference, since it can make it a lot easier dropping a trans pan, or less spill changing oil.
