Default NAPA Synthetic Oil

Has anyone used the Napa full synthetic oil? Any reason to stay away from it? It is one sale this month. http://www.napaonline.com/Flyer0710/Main.asp

I am planning an oil change and thought I might use it this time.

It does not say what specs it meets. If it does not say on the label that it meets the GM 4718M spec, stay away.

You should look to see if it meets GM spec "GM 4718M"

P.S. Tom73 beat me to the answer. Great minds think alike!

Mobil1 is sale priced at Wal-Mart. Why would you want to experiment with oil?

I would pay $20/quart for Modil one before I would ever shop at walmart!

As long as the NAPA oil meets the GM specs I think it would be fine. I am sure some other company manufactures it for them. You may want to try and find out who makes it for them. But, I prefer to spend the extra and run Amsoil or Royal Purple. Just my $.02...

I don't understand why. They have great prices there. It's usually $20 for a 5 quart jug of Mobil 1.

For starters, wally world has been horrible for America (just do some research if you don't believe me.) Second, I cannot stand to be in the store for more than 5 minutes. As a matter of fact, I have not been to wally world in 3 years or so. Third, there is nothing they sell that I cannot find for an equal or better price somewhere else. Finally, you are going to get door dings in their parking lot, because, most of the shoppers are lazy and stupid! I don't understand why you cannot push a cart 5-10 feet to a cart corral?

If you read your owner's manual, you'll see that GM does allow alternatives to the 4718M spec. There is a good article here:

http://www.idavette.net/hib/C5diy/c5diy1.htm

Scroll down to "What kind of oil?"

Here is an exerpt.

The second oil selection issue to address is the Service Manual statement that LS1s operated in North America use only an oil meeting GM Standard 4718M. The Manual also states that oils meeting 4718M might be hard to find outside North America and that LS1s operated in such places can use any 5W-30, 10W-30 or 10W-40 petroleum or synthetic oil meeting APIĘSJ and Association des Constructuers Europeens de l'Automobile (AECA) Standard 3-96.

I use Castrol 0w-30 full synth, German made. Excellent oil analysis results.

I use Castrol 0w-30 full synth, German made. Excellent oil analysis results.
Here is what the '04 owners manual says:

Look for two things:
• GM4718M
Your vehicle’s engine requires a special oil meeting GM Standard GM4718M. Oils meeting this standard may be identified as synthetic. However, not all synthetic oils will meet this GM standard. You should look for and use only an oil that meets GM Standard GM4718M.
Notice: If you use oils that do not have the GM4718M Standard designation, you can cause engine damage not covered by your warranty.

• SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it is going to be 0°F (-18°C) or above.
These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.
Oils meeting these requirements should also have the starburst symbol on the container. This symbol indicates that the oil has been certified by the American Petroleum Institute (API).
You should look for this on the oil container, and use only those oils that are identified as meeting GM Standard GM4718M and have the starburst symbol on the front of the oil container.

Your vehicle’s engine is filled at the factory with a Mobil 1® synthetic oil, which meets all requirements for your vehicle.

Substitute Engine Oil: When adding oil to maintain engine oil level, oil meeting GM Standard GM4718M may not be available. You can add substitute oil designated SAE 5W-30 with the starburst symbol at all temperatures. If temperatures are above 0°F (-18°C), you may substitute SAE 10W-30 with the starburst symbol. Substitute oil not meeting GM Standard GM4718M should not be used for an oil change.
