I just got this directly from VW in an Email. At the end of the email vw says you can use viscosities other than the 5-40 mentioned in the manual.
The gasoline used
in your vehicle
really does make
a difference...
Volkswagen is now part of a group of leading automakers calling
for higher gasoline standards.
Volkswagen, along with other top auto manufacturers, recognizes that the current Federal mandates for minimum detergent requirements for gasoline do not go far enough to ensure optimal engine performance.
This group of automakers is raising the bar, calling for a premier standard of gasoline performance, with TOP TIER Detergent Gasoline standards. These standards create a winning situation for gasoline retailers, auto manufacturers and drivers.
The issue
Currently, many gasoline retailers provide fuels with lower-quality additive packages that can build up deposits on fuel injectors and on intake valves. Others can build up deposits in combustion chambers and may lead to intake valve sticking. These lower levels of additives can have a negative impact on engine performance and vehicle responsiveness.
Since the minimum additive performance standards were first established by EPA in 1995, most gasoline marketers have actually reduced the concentration level of detergent additive in their gasoline by up to 50%. As a result, the ability of a vehicle to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and driver satisfaction.
The solution
TOP TIER Detergent Gasoline standards help drivers avoid lower quality
gasoline which can leave deposits on critical engine parts, which reduces engine performance. That’s something both drivers and automakers want to avoid.
Here are the retailers that currently meet TOP TIER
Detergent Gasoline standards:

Choosing the right oil
matters a lot more today
than it used to.
The power plant in your Volkswagen is one of the most advanced and sophisticated engines available today. Built to precise specifications, it requires an exact grade, viscosity and quality of engine lubrication.
Many synthetic oils available today provide better engine lubrication that can outlast traditional petroleum-based oils making them a smart choice for use throughout the life of your Volkswagen. Because of this fact, Volkswagen strongly recommends that you use synthetic-based oil that complies with Volkswagen oil quality standard VW 502 00 as a replacement lubricant for your engine.
Whether you use synthetic or petroleum-based engine oil, the oil that you use must conform to Volkswagen’s oil quality standard VW 502 00 in order to help keep your vehicle’s engine running smoothly and help prevent the formation of harmful sludge and deposits that can lead to expensive repairs. At the time of printing, engine oils available in the U.S. that meet the standard are synthetic oils.
Engine oil specifications for gasoline engines in 2005 and newer
model year Volkswagen vehicles
Specification and viscosity
Your gasoline engine was factory filled with all-season, high-quality engine oil that conforms to Volkswagen oil quality standard VW 502 00.
If you need to add oil between changes, or perform an oil change, use only an engine oil with the correct specifications that complies with Volkswagen oil quality standard VW 502 00.
To help prevent the formation of harmful sludge and deposits, use only oil with the Volkswagen oil quality standard VW 502 00 specification printed on the oil container.
Engine oils are graded according to their viscosity
The proper viscosity grade oil for your gasoline engine depends on climatic or seasonal conditions where you drive. You can use oil with a viscosity grade of SAE 5W40 across all temperature ranges for normal driving conditions. However, if engine oil viscosity grade SAE 5W40 is not available, you can also use viscosity grade SAE 5W-30 or SAE 0W-40 as long as it meets Volkswagen oil quality standard VW 502 00 specifications.
