the info with my motor/driving habits and such.
first i must say that my motor is a mystery. it has reoccurring issues that no one is really able to figure out. so a rebuild may be in store...
the motor has 325,500 miles to date, original motor,tranny, everything is original, no rebuilds nothing. as long as I can remember I have used Mobil 1 full synthetic 10w-30, I recently obtained the cherokee from my dad (it is a 1999 by the way) from what I know he has always used mobil 1 products and I would like to keep it that way. he has used different weights but the last 100k for sure has been 10w-30. every now and then I can hear a knock/tapping noise which i am hoping isnt from a lifter, but with this many miles...
my dad said it really has always made that noise and it isnt anything to be worried about, (he works on high end race cars so I'm trusting this advice) other problems are it having a messed up exhaust (leaks from header as well as multiple places down stream) it has a random misfire that occurs when you rev it to high for to long, which is cleared up by, you guessed it, reving it even more lol. recently I have put in Lucas Oil heavy duty oil stabilizer, I heard that stuff was junk so I stopped, on my last oil change I used a silver can from auto zone, it was simply called engine restore, apparently it eats all the sludge and from what I experienced it gave a smoother idle literally 5 seconds after start up, and the throttle was a lot smoother and responsive. Is this stuff worth continuing use?
i live in arizona where the summers can see 120+ degrees, and the winters Im up early in low 30s, I also head up to the snow often. my stepmom who put the first 200k miles on it drove it like a race car, she has road rage issues...my dad put on 50-70k after that and he drove it easy, then from there to here i try to drive it easy, but i do get on the gas quite a bit. id have to say most of my driving is highway/freeway at 75-80mph. although I do go through lots of stop and go to get to the freeway and sometimes sit in stop and go on the freeway.. I use fram tough guard filters, I also heard these were junk. they are known to cause oil pressure issues, but for others they are perfectly fine, I have the dummy guages so I have no way of monitoring my oil pressure, do you think I should switch to a higher end filter like Mobil 1 filters? the only thing I have to say is, the filter I dont care what brand I use, the oil I want to continue using Mobil 1. do you guys think i should switch to extended guard, high mileage or keep it with the regular stuff, any weight suggestions? hopefully only have to see one more AZ summer then I'm off for the air force next year.
oh also, I do change the oil every 3-5k, the longest I have gone personally without a change was 7k. the rear main leaks and I am always adding in more and more fluid so at the time I wasnt to worried cause it was getting fluid often...
