I bought a '98 Camry, 4 cyl, with 60,000 miles on it. The motor seems prety clean inside, from what I can see. For my 1st oil change I mixed 2 quarts of Mobil Drive clean and 2 quarts of Mobil 1 synthetic, both 5w-30. (Actually 3.8 qts total). The oil has 2ooo miles on it, and is still very clean. This car is a snap to change oil on. I bought 4 quarts of Mobil 1 Synthetic at Wal-Mart. $3.60 a quart, everyday price. The other 2 wal marts are 4.50 qt. Then I noticed Advanced auto had the Havoline 5w-30 synthetic on sale for $2.98 a quart and I bought a case of 6. This is the blue Chevron-Texaco bottle. Is it any good, should I stock up on more, and should I do the Havoline of Mobil for my first oil change?
