Re: 5W-30 on the Autobahn?

["Ron Buchalski" <rbuchals@xxxxxxxxxxx>]

Henri,

5W-30 is a multi-grade oil.  When it's cold, it has a 'weight' of 5 (the W 
stands for Winter, not weight).  When the oil is heated to operating 
temperature, it thickens up to a 'weight' of 30.

On a recent trip to Germany (August), we visited a BMW dealership in Munich 
and purchased some parts.  The oil that they were selling was 0W-30 
synthetic.  In August.  For cars that drive on the autobahn.  IN a country 
where gasoline costs over $4/gallon.

So, it's not a USA mandate to run lighter weight oils in cars to improve 
fuel economy, at the expense of engine life.
