Hello All,
Need some perspective on the used motor oil that I drained/filled today on my personal truck.
-1999 Chevrolet Silverado single cab
-5.3L V8
-79,200 miles
-2 wheel drive
Purchased the truck with 75K miles and changed the oil when I got it to Castrol Full Synthetic 5W30 with an AC Delco PF46E filter. The original owner "said" he only used Mobil 1 however receipt records in the glove box say otherwise, so who really knows. I wanted to take my time in cleaning the motor and any potential build up it may have so here has been my approach. I changed the oil again at 77K miles and today once again at 79K miles. At both the 77K and 79K mark the oil appeared fairly clean (dark honey in color) which put a smile on my face, however on all 3 OCI's there have been 8-12 micro sized blue plastic shards found on the screen of my funnel when I pour the used oil out of my catch can and back into the 1 gallon jug to take for disposal. What in the world is this, has anyone else seen this? On a high note the truck runs wonderful, it's quiet and has lots of power. Thanks in advance everyone!
