High nickel in used oil analysis Jeep
Asked by JacquesRothAnswer
THE TESTING FACILITY, HAD NO CLUE?
MY BEST GUESS WOULD BE ENGINE BEARINGS, CRANK, CAM, ETC
I'VE NEVER READ INGREDIENTS ON THE PACKAGING! LOL!
MAYBE A GOOGLE SEARCH WILL TELL COMPOSITIONS...I'LL GO LOOK!

GAS / DIESEL......SAME THANG!......I RECKON A BEARING, IS A BEARING! MANUFACTURE'S PROCESSES MAY VARY. BEARING MUST BE MADE FROM HARD STUFF TO LAST AS LONG AS THEY DO.

BEEN THINKING ABOUT THIS.....
ARE YOU HAVING VEHICLE ISSUES?
WHY WOULD YOU HAVE THIS TEST DONE?
WHO SUGGESTED IT?
HOW MUCH DID IT COST?
AFTER THE TEST AND YOU WERE GIVEN THE RESULTS, WHAT WAS SAID OR WRITTEN, OTHER THAN THE COMPOSITION OF YOUR OIL?
NEVER DEALT WITH THIS BEFORE, ANY INFO YOU CAN PROVIDE, MAY HELP ME IN THE FUTURE.
THANK YOU!

So far I have had no vehicle issues. I am a pilot and knew oil analysis was often used for aircraft engines. I am just concerned about the mileage on the engine and was hoping to get an early warning if it was about to fail, so I could put a new engine together beforehand and not be stuck for a long time without it. But I don't know if this is the big warning or not. Oil Analyzers, Inc. just gave me a list of quite a few possible sources of nickel -valve plating, shafts, gears, roller bearings, liners (which the engine does not even have). The two reasonable suggestions people have made are valve plating and wear of the babbitt on the bearings exposing nickel underneath. But I don't know which for sure or perhaps there is another cause.
