I have a 2002 Sentra 1.8, only has intake a little less restricted, and advanced timing.
On this sample it had GC 0W30.
But right now it has 147,000 miles and it's using a mix of half/half Amsoil Signature Series 0W30 and Pennzoil Platinum Synthetic 5W20.
After this analysis, I added a bottle of Subaru Coolant System Conditioner to the radiator.
