What is a good brand of oil to use in a 2004 4cly Camry?

All major brands are Excellent. If your Camry has over 100,000 miles on the ODO I recommend you use a High Mileage oil. I personally use Pennzoil High Mileage SAE 5w30 in my Toyota Truck with 135,000 miles. It does not use one drop of oil and runs perfectly. Just make sure you use the correct weight that is recommended by Toyota.
