Here are the latest oil analysis results from my 98 Corvette
Analysis by Wearcheck Canada
5800 miles on oil
Nov 14 to July 18 (8 months)
106,000 miles on the car
Pennzoil Platinum 5w30
NAPA Nascar oil filter
Vararam cold air kit (with a cotton gauze filter)
LS1 5.7L V8 engine
7 qt oil capacity
1.5 qts of makeup oil added
Oil life monitor was at 12%
Iron 18
Lead 3
Aluminum 12
Copper 1
Chromium 2
Tin 1
Silver 0
Titanium 0
Nickel 0
Silicon 11
Potassium 0
Sodium 0
Boron 38
Barium 0
Vanadium 0
Manganese 1
Sulfur 2301
Calcium 3257
Magnesium 19
Moly 57
Phosphorus 763
Zinc 909
Oxidation 69
Nitration 53
Sulfation 57
*note, the above three values are not percentages*
ZDDP 17.5
Viscosity at 40c 58.7
Viscosity at 100c 10.9
Viscosity Index 180
I changed the oil earlier than I had planned (I always wait for the oil life monitor to hit zero) because my Fram Sure Drain plug system was starting to leak oil and messing up my garage floor. Luckily I had a spare new one to replace it.
I refilled the crankcase with Pennzoil Platinum 5w30 again, but this time I am using the Fram Extended Guard oil filter.
