JK maintenance..

Hey Guys and Gals..

Does anyone do their own maintenance on the JK? I do everything to my TJ, but since selling my DD in favor of adding another Wrangler family, I was curious as to how difficult these tasks are (i.e. Oil, Diff, etc.).

She has about 600 miles on her and I want to change the oil at 1K after break-in and was wondering what kind of oil everyone likes... I use a Purolator Filter and Castrol High Mileage in the 2000 TJ..

Also,

Does anyone know how to unearth a FSM for the JK (2009).

I changed my oil the first time at 3k because I believe it provides a proper break in.

Wait till 3k and then do conventional oil. Purolator oil filter is good, but don't do synthetic till 6k plus. That's just my professional opinion.

Be aware- some oil filters are having drainback/dry start issues, even with anti-drainback valves. If you park with the nose pointed uphill, you may have these issues.
Also, I agree on waiting until 3K miles, BUT only if you plan to swap to synthetic at 3k. Otherwise, there's NOTHING wrong with changing at 1k if you're sticking with conventional oil.
Otherwise, follow your maintenance schedule, unless you do heavy off-roading- then, step it up from 6k miles to 3k- Mark W.

Also make sure your drip pain is a good 3 feet beyond the drain plug.

Thanks for the input guys.. I haven't even cracked the owner's manual.. So, 3K huh?? I have always been taught to change a new car's oil at 1K to drain all of the initial metal shavings from break-in..

So, what kind of Oil does everyone use?

Thats true, first oil change at 1000 to 1500 miles. Good rule of thumb.

Those were the old days. Read you manual. Your Jeep came with regular oil, not "break in" oil.

^Yes, but your engine still breaks in. Clearances will open up, friction will cause some extra metal shavings to break loose into the oil. The only way to get rid of them is a good old fashioned oil change- Mark W.

Royal Purple. I change at about 6000 miles. Could go up to 10,000, but I'm a stickler on my maintenance.

Must Say

Really, Metal shavings and such in a new engine. Wow. I cant believe that 'New Engine" failure rate is not astronimical. I have owned multiple new vehicles and have never had metal shavings in my oil. Yes change out the new oil at 500 miles....for peace of mind if nothing else.

Break In - The engine is at 750 to 4000 rpm, every minute. The piston rings are subjected to "how much" linear motion, and thus wear every second the engine is running. How long do you really think it takes to seat a piston ring. This could be measured via cylinder compression but....how many of us actually measure a new engine compression and then subsequent measurements until a optimal reading is obtained. Then switch to Syntethic Oil. Just run a few 500 mile cycles of conventional prior to switching to synthetic. Not complicated at all and you will be fine.

PS: Mobil 1 after the intial breakin. No KN Air filters in my desert environment.

Hate to tell you brother, but EVERY engine at ANY amount of mileage has metal shavings in the oil- why do you think you run an oil filter? Bingo. They are FINE particles, but they're there. The most common time for them to occur is during engine break-in, when wear on piston rings, cylinder liners, cams/lifters, etc. (essentially all points of contact of compression) is highest.
The way to check how bad it is is cut open your oil filter, and look inside. You WILL find metal shavings- if they get big, you have problems- Mark W.

All this worry about engine wear as if you're going to keep it forever. I change mine at 6K and didn't change it before that even on the breakin. I always buy a car new and keep it for usually about 10 years. This usually amounts to between 100K and 200K miles on it when it is traded or sold. Pay attention to the maintenance schedule in the owner's manual and follow it faithfully. Your jeep will last a long time under those conditions. Several cars, between my wife and me and no oil burning problems. Now, I know that some folks have this as their hobby and in that case it is really a labor of love. To those I say whatever turns your crank. Otherwise have a blast using it for what it is intended for hopefully off road once in a while.

Duke, I knew I would take a hit on this. I assume everybody uses an oil filter. Knowing this, one must assume that metal in any form, that can be captured by the filter, will be. My point is this. Why worry during the breakin period, about these metal particles, when the filter is going to catch them anyways. If the particles are catastrophically large, something major is wrong and your dealer will probabely be involved. Other that that, I agree. Change your oil regularly, use good oil, and a quality filter. I just dont get freaked out about it.
I guess what caught my attention and the reason behind my reply, was the term 'metal shavings'. No harm meant

Changing your oil at less than 5k is a waste of money. Oil manufacturers want you to change it every 3k to line their pockets. In the old days, it had to be every 3k. But in this time of nikasil lined cylinders, 5k on conventional oil is fine. If you run sythetic, you can do up to 10k. But spin on a new filter and top off at 5k. It's not the oil that goes bad, it just gets contaminated.

No worries- I was just establishing a position- a hangover was involved... yeah Anyways, a break-in oil change is never a bad idea. During break-in, there is a lot of friction, so the oil filter may become somewhat clogged- that's why they all have a bypass valve- after it can't filter anymore, it will simply let everything bypass the filtering element. Does this happen often? No, but I DO plan on keeping this vehicle until it rusts out from under me (which I plan to stave off as long as I can), so not having to replace an engine ever would be nice
If you plan to keep the Jeep 1-5 years, disregard, and stick the next owner with the bill Mark W.

Mark,

Based on my experience, I would extend that 1 to 5 years to 10 to 15 years, then stick the next owner with it. By that time the jeep will owe you nothing and its resale value will agree. I've done that with several vehicles and even after 10 years, they were not pushing oil. So with my vehicles the next owner probably got a deal according to your logic? (because the engine didn't need changing) I've always used schedule A maintenance which is the longer oil change interval.

I had a VW Golf once. Changed the oil at 56K, two days in a row. Traded it in for a truck the next week. That was just wrong.

Wow, how true is that. I had a huge pan and I missed nearly the first 2 quarts of the drain by not having it properly aligned.... what a @$@$ mess.

Chalk that up to stupidity. Luckily all of the mess was contained to the floor of the test guidance facility at work and not my garage....LOL

Did my first drain at 1000 miles to clear out the factory oil and impurities.
Refilled with conventional dino spec. Did my next at 3500 miles. Moved to synthetic oil & filter. Did oil analysis and all good.

I would just follow the maintaince manual.An oil change at 500 or 1500 miles is a waste of money.If you off road then you should change your oil every 3000 miles.There are no car manufacturers that would recommend that type of maintainance(at 500 miles).Your Jeep doesn't need that type of attention,if you prefer to do that go right ahead,it can't hurt.An oil change at 500 miles doesn't seem right,maybe in the 60's the cars should of had that type of treatment but not anymore.Hey ,you can never treat your jeep too good, right? Have fun!!!!!!!!
