I've been having very heavy oil usage of late, even greater than the Jeep referenced "standard" of 1 qt/1000 miles. It has resulted in my 2007 being more than 3 quarts of oil low without the idiot light even coming on. I know, check the oil more often, but really, it's a relatively new car and who really thinks they should have to check the oil every 1000 miles on a newer car.
Anyway, there's plenty of comments going around on various boards. Couple of questions if anyone wants to provide some input. Dealer service said a faulty PCV valve can cause heavy oil consumption - no I have no obvious leaks at all. Recommended to replace to PCV. Anyone have a picture of its location? I think it's tucked someplace sort of hard to find/get to. Any tips on changing it?
Bigger picture question is should I be immediately concerned about any potential engine damage already done with running low on oil before noticing it - even if the engine light never came on? I regularly change oil at 3k miles, but I had the oil pressure light ding and come on for 1 second the other day and turned right back off, so I checked the oil, finding it very low.
