had 4300 miles on the syntec.
As bad as this sounds, i may drain it for something a little thicker. The car was warm when i first drove it after i changed it, but i dont know what the oil temp was. I ran it to redline to see how the car felt after about 5 mins of running (coolant temp was already up). Above 6k rpms i heard this noise almost like a rattle. I dont know if it was the exhaust shield i was messing with or lack of oil pressure to the valve train. I'm praying it was not the latter. I tested it again after i was driving on the highway for a few mins and nothing but sweet engine sound all the way to 6800 rpms.
If it was an oil pressure issue, and insufficient oil pressure was reaching my valve train, shouldnt the oil pressure light be on? Is it possible its too thin for this engine? Or am i just nuts?
And i paid 5.99/qt at AAP.
