I recently bought an '87 Syncro.  Having never owned a VW, I'm not used to
running the engine at a higher RPM rate like people have told me.

The speed seems to max out at around 3500 but I give some more gas and get
it past 4k before shifting, but I've heard you should go atleast 4.5k or
5k.  I was hoping to get input on what others typically run their vans at
before shifting up.

Thanks
