Volkswagen rarely limits the thier vehicles especially their four cylinders to just using medium of high grade fuels. You should have no problem using any grade of fuel in you volkswagen. use shell 87. It's my favourite for power and mileage. Your vehicle requires a minimum octane rating from fuel to run smoothly because of its ability to ignite the mixure. Octane rating describes fuels willingness to ignite under pressure. Lower grade fuels are actually easier to ignite so in a premium vehicle where the tolerances in the engine are tighter a lower grade fuel may ingnite prematurely due to the pressure in the engine and not due to the firing of the spark plug. This is known as knock(or piston slap) and is very bad for an engine and will eventually lead to complete failure due to a hole in the piston.

We just purchase a 2010 CC sport 6spd manual. Wondering which grade would be best? If we use Shell 87 octane will we sacrifice power or fuel efficiency- lower miles per gallon compared to 91 or 93 octane?

Look on the Gas Door it should say which is suggested to use. I have a 2012 CC 2.0 Turbo and it suggests 91 or above. I also asksd and it is known that you will not get the best gas mileage under 91. Hope this helps

The Octane rating will affect the performance & fuel economy of just about any vehicle. If you are not Racing your car or looking for the best mpg, 87 Octane is just fine. You can experiment with the higher Octanes without compromising any damage to you motor. Try using fuel system cleaners & follow manufacturers recommendations. These will clean interior parts in your fuel sytem for peak performance & better mpg without having to use the higher Octane. Good Luck....
