Hello,
This is my second UOA on my Montero. The oil change in 2014 was Royal Purple 10w30 and the latter PUP 10w30. The aluminum and copper have me concerned. The Montero does have an oil cooler, but the truck is 23 years old. At least my iron was down, but viscosity changed. I changed the oil to PUP5w30 (currently). I change oil in Severe service, so next time will be at 3,000. I estimate approx 50 miles was 4x4 in various Hi/Lo in the mountains at high elevations 7.,000 >. I'm open to opinions/suggestions. Considering a different oil and interval. *It took 13 days for BlkStn to receive UOA from NM, via USPS. Great service from BlkStn. They hadn't receive the package until today.
Respectfully,
Pajero!
