Used oil Analysis Factory Fill


Recommended Posts

Was curios about Factory fill YES I dumped it early but OLM was at 81% Mostly Hwy 80 /20 split I belive TBN is aprox 6.6 based upon AC delco 5w30 VOA. Engine uses timing chain so I didn't want it to be like the Traverse fiasco with the OLM getting recalibrated (service)

OIL USE INTERVAL 2377KM
FACTORY FILL 5w20

Oil was in use for 2 Months April 2nd- May 25th


REMARKS (From Blackstone Laboratories) MICHAEL: It's normal to find higher metals and silicon in a brand new engine. Iron and copper are from steel and brass/bronze parts. They read higher than average here since they're from brand new parts wearing in and getting comfortable in your engine. Silicon is from the harmless sealers the factory uses to put the engine together. These materials should wash out with a few oil changes and we'll be able to compare your engine to universal averages, which are based on about 6,000 km. The TBN read 4.4, still a
good reading. Check back to build trends

Thoughts on this? I will going for official Oil change end of july then will be doing every 4 Months or according or OLM

Metals in PPM would be from the following :

Aluminium is from : Pistons/ bearings /Cases (heads/block)

CHROMIUM : Rings

IRON : Cylinders , rotating shafts/ Valve train any part of steel sharing the oil

COPPER :copper bushings/bearings brass or bronze parts

LEAD : Bearings

TIN : Piston Coatings , Bearings, Bronze parts
