What Kind of Oil to Use Go Top
Oils recommended for use in your vehicle can be identified by looking for the "Starburst" symbol. This symbol indicates that the oil has been certified by the American Petroleum Institute (API) for gasoline engines. Look for a major brand of oil meeting API SJ or ILSAC GF-2. If you're outside North America use an oil that meets AECA 3-96.
What Weight Oil? 0W-30, 5W-30 10W-30?
GM recommend 5W-30, but the reason GM recommends 5W-30 is that it's the politically correct choice when fuel mileage is a prime consideration. The U.S. Environmental Protection Agency, which oversees fuel economy standards for cars sold in the U.S.A and believes 5W-30 oil is a significant energy conservation measure. The EPA has pressured car companies into using 5W-30s in their new vehicles. In response to this pressure, many years ago a policy was made by GM at the corporate level that, with few exceptions, the recommended oil for all passenger vehicles will be 5W-30.
When you read the "Maintenance and Lubrication" section of any GM Service Manual, you will soon discover that there are alternatives -- "The recommended SAE engine oil viscosity is 5W-30, however, if the temperature is above –18 C (O F) 10W-30 may be used." If your engine is regularly operated where outdoor temperatures are above 0 F using an oil of different viscosity range might be better in the long run.
Why?
Any 5W-30 engine oil, including the synthetic, uses chemical additives, called "viscosity-index improvers" (VI), to widen its viscosity range enough to make it qualify for a 5W-30 rating. VI improvers contribute little to lubrication and can make a "multi-viscosity" oil less effective at high temperatures than an oil without them. Another characteristic of a 5W-30 that can be a problem in severe service is a relatively high evaporation rate at high temperatures compared to lubricants of more narrow viscosity range. A higher evaporation rate contributes to increased oil consumption and substandard lubrication in areas of high temperature.
There are no VI improvers in quality, 10W-30, synthetic engine oils and their high-temperature evaporation rate is less. Thus, 10W-30 synthetics are better lubricants in severe duty applications.

A good choice is Mobil 1, 10W-30 synthetic. Mobil-1 is made with a synthesized-hydrocarbon, base-stock and Since GM endorses Mobil-1 (Corvettes come from the factory with Mobil-1 in the crankcase), so it doesn’t hurt to go with what GM uses.
Synthetic oils offer the only truly significant differences, as long as its approved to be used in your car, due to their superior high temperature oxidation resistance, high film strength, very low tendency to form deposits, stable viscosity base, and low temperature flow characteristics. Synthetics are superior lubricants when compared to traditional petroleum oils.
You can start using synthetic oil in new vehicles at any time. In fact Mobil1 is the factory fill for the Corvette LS-1, LT-1 and LT-5 engines. Mobil and Porsche also have a partnership whereby all Porsche cars manufactured at the Zuffenhausen plant will be lubricated with Mobil 1. One of the myths that still persists about Mobil-1 (or any synthetic oil -- Red Line, Castrol Syntec, Havoline Formula3 Synthetic) is that new engines require a break-in period with conventional oil. Current engine manufacturing technology does not require this break-in period. As the engineers who design Corvette and Porsche engines indicate, Mobil 1 can be used in an engine from the day you drive your car off the show room floor!
