'10 Chevy Corvette 6sp Manual
No Make-up Oil
No Additives
Miles on unit-16k
Miles on Oil 5k
Filter-Fleetguard LF16242
Lots of hard pulls, Summer heat, idling.
Blackstone comments: You used a longer run than last time and wear metals are mostly lower. Lead and Tin inched up just 1 ppm, which is hardly enough metal to even mention. These numbers are fantastic after 5,000 miles of oil use so no mechanical problems or poorly wearing parts stand out. Fuel, water, and coolant contamination remained absent, and the air filter did a good job with airborne dirt (see silicon). Low insolubles show the oil filter didn't have a hard time with oxidized solids (insolubles). The TBN read 4.2 - plenty strong since 1.0 or less is low. Excellent report!
Previous fill was Castrol Magnatec 5w-30 Green Bottle, only 4k.
