We have a 2005 Passat TDI. And I just received a notice from the dealer for "Supplemental Oil Change". What is this and why do I need it? Or is this a dealer gimmick?
Have had zero problems with the car and they did the 10,000 mile service when it came due. We haven't hit 13000 yet.
The manual lists standard oil change intervals but usually has a comment that oil should be changed at shorter intervals if the car is driven in the cold, does short journeys, is used for towing etc., etc. The "Supplemental Oil Change" is usually justified based on these subjective criteria. All organizations that make money from changing oil suggest more frequent oil changes than the car manufacturers. Many people argue that its cheap insurance.
Unless it is as Christopher suggested a change based on time not miles (you would need to be a low mileage driver and I really don't think that is going to come into play for a 2005 car yet) then it is supplemental income to the dealer.
BTW remember that you don't need to have any of that maintenance done by the dealer. It needs to be done, but it can be done by yourself or an independent mechanic and you can save a few dollars.
It was my understanding by reading this group that hardly anyone but the dealer was able to acquire the correct oil for this car. Or is it available, but for an outrageous price?
The owner's manual will tell you what specifications the oil must meet. Likely a 50N.NN number and maybe a CX-N code. Oils meeting those specifications may take a few months to reach the public after a new car and specification is released.
I know the oils required from my 2002 TDI can be found at many locations including Wally World.
Not only do you need need to buy your oil from the dealer, you do not need to go there for service, other than warrantee service.
