I've been lurking for a while, asking questions regarding others' auto matters, but now it's time for my vehicle's next oil change.
Vehicle Info:
Since I have all the service records (in Excel to boot!), I know the car had religious OCI's of 3,000 miles. None but the last entry prior to my owning it listed the type of oil used. So when I bought it in 6/2015 it was running PYB 10W-40 with a Fram Tough Guard.
My history
Mobil 1 0W-40 with an M1-301 filter at 79,000 miles. The 0W-40 created a lot of valve chatter. Made me nervous.
Drove 500 miles, put in a new M1-301 (read somewhere it was a good idea...who knows).
1,000 miles later, changed the oil and filter to Mobil 1 5W-30 & M1-301.
Next OCI was 7,000 miles (7 months) later with the 5W-30 & M1-301.
I'm right at 5,000 miles since the last OCI and thinking I'm wanting to change the oil now before winter sets in. I'll be ordering a UOA (have the kit) to see what's what, but in the interim, I'd like some opinions and input. For what it's worth, I'm happy with the current Mobil 1 5W-30, M1-301 setup. That being said, I've read on here that M1's 5W-30 may not be all that stellar. I've also read that some XJ folks have had good luck with Castrol and Rotella (T6, I think, which is now TS??).
If you're not yet rolling your eyes, or even if you are... let's have it! Oil is getting changed in the next day or two.
Vehicle Info:
- 2001 Jeep Cherokee Limited
- 92,XXX miles (I'm the 2nd owner. 1st owner was a Jeep Dealership mechanic, bought it off the lot, took extremely good care of it and kept records. Buuuut, never washed it during the Pittsburgh winters and thus the underbelly is covered in rust)
- Driven in Virginia; lives on a dirt road; sees a bit of light off road, but mainly driving up and down the foothills of the Blue Ridge and long shots up and back to NYC
- Driven conservatively...that in-car computer is always tuned to the Avg MPG display... and relatively babied. I'm just looking for solid engine protection and efficiency
- Only issue seems to be a worn out kick down cable that causes the transmission to not kickdown when desired. No leaks, no burning oil, nada.
