i have a 08 rubi that doesn't leak anything, i drive probably somewhat aggressive, no highway speeds though we don't have a road long enough for that speed, but it's subject to extreme conditions in the winter and has over 55000km

My 2008 has 38K and isn't a daily driver, when it's driven we normally check the oil. I have a good relationship with my local dealership so I've let them service my JK since new. I get the oil changed every 5K and never as of yet has it been low of oil.

My '08 JK UX has about 65K on it now and has always been down 1 qt. after 2K miles since it was new. No leaks anywhere. 3.8L / Stock completely. Ive always put regular 5w-20 in it although I have tried 5w-30 and 10w-30 in the past for a change interval just to see if it made any difference. It did not. Dealer said its normal and within specs for this engine and said to just change the PCV to make sure that was contributing. I keep an eye on the mileage and when I get near 2K I pull into the Oil Change place for their free top off.

My 07 has 73000 on it had it since 60000 I would say it would use a qt every 2500 miles or so and I can live with that.

I can live with some oil burning, I just don't wanna get one that drinks a quart every 1000 miles or something. If I do, I'll just deal with it, but I'd much rather get one that doesn't!

My wife's early 2007 with 58k miles uses no oil between changes. But it sees light duty as you can see from the low mileage.

Dealer told me that up to a certain point in 08, the bottom ends were made in Mexico (or something like that). Poor builds were causing the excess oil usage. The problem was recognized and from then on the motors were constructed elsewhere. The dealers have a tolerance of oil usage. I am currently doing a consumption test as I type. The limit is staggering too. It's something like 1 liter used per 1500 kms IS acceptable. I wasn't even reading on my dip stick between oil changes. Anyways, finding out if it's "alright". The dealers are aware and they do know why. Don't let them tell you otherwise.

Welcome to The Dark Side...we have cookies.
One time I changed the oil, it took almost 12 qts...until I realized that I forgot to put the drain plug back in. D'oh!
Mine burns far less than a quart/1000 miles. Not too worried.

You'll never have to worry about forgetting the oil plug !

I have a Fumoto valve now. After installing an oil pan skid plate (River Raider), that thing is worth the $$. Much easier...and cheaper (less oil wasted, haha!).

113,000 miles. '07 JK. I can see some oil usage on the dipstick over time, but never goes below the safe range. I change every 3000 miles with 5w20 oil.

Mine has 86k but, 18k on the new short block. The first engine used about a quart to quart in a half every 3k and also had a spun rod bearing from the get go. One of the Don Pueblo specials I suppose. My current engine harldy uses anything. 3,000 miles still in the safe zone if any oil was used it was very little. I changed my PCV valve and on this last oil change I have put almost 4,000 miles with no oil usage at all. It was time for a PCV valve replacement anyways. Valve wasn't stuck but had a good amount of wear which can cause some oil consumption as well in these engines. Most of the major consumption has been either rings installed upside down or poorly honed cylinder walls that don't have good cross hatching. The other problem on some early JK's were spun rod bearings from poor machine work on the bottom end of the engine. Mid 08 on should not have this problem. I know a few people with late 08s as well as 09-11 with no issues some with 100k on the clock. Its a very solid engine when the rings are installed right and machine work is done correctly.

Can you describe exactly what was worn on the PCV valve?
