My engine is burning oil after 200k miles. See number 6 for details. Also my father seems to think I should switch to 10w-30 and use lucus oil stabilizer. First off if my owners manual says 5w-20 (I currently use pennzoil high milage 5w-20) is it safe to use 10w-30? Also is that lucas stabilizer even necessary? Thank you. Below are my vehicle details.
1. What kind of vehicle you have-2009 jeep grand cherokee 3.7L 4x4
2. What your owner’s manual says - says to use SAE 5w-20 API certified engine oil
3. Where you live- northwest florida
4. How you drive (easy? hard? fast? slow?)easy and slow. Only drive fast when making a u turn through highway emergency vehicle median haha.
5. What your daily drive is like (short trips? long trips? city? highway?)first 0-60k miles I have no idea(I try not to buy new vehicles). from 60-160k miles it was mostly all highway miles. From 160k-205k miles it was even city/highway.
6. Whether your car has any known problems (leaks, oil consumption etc)- at around 200k miles started to use/burn/consume/magic alot of oil. Basically it would read at the top of the safe line on dip stick after an oil change and 2 months after oil would only show up at the tip of the dip stick...nowhere near the safe line (I can kick myself). Also I have funny noise humming noise comming from ujoint or front differential. Pretty sure it's ujoint.
