Read more about the differences between true Synthetic oils using Group IV Polyalphaolefin (PAO) base and Group III "Synthetic" oils that use modified mineral oils as a base: Synthetic Oil Explained
Quick OverView:
Group 3 - this is a highly refined mineral oil made through a process called hydrocracking. In North America this group is considered a synthetic oil, for marketing purposes.
So, while Volkswagen of America may have approved Castrol, that does not mean it is any good for your vehicle - don't forget; their biggest source of income is not from selling you a car but selling parts and performing service on it.
N.B. Amsoil is not approved nor is it recommended for these German vehicles
Group 4 - these are true synthetic oils, known as Polyalphaolefin (PAO).
LubroMoly and Motul are true Group 4 synthetics that contain the proper additives required by Volkswagen Germany for use in their Volkswagen and Audi vehicles. Additionally, they meet all requirements necessary for BMW, Mercedes Benz and other European marques.
The MoS2 anti-friction lubricant forms a high load-bearing film of lubricant on all friction and sliding surfaces. The MoS2-lubricant film reduces the resistance to friction and allows engines to run so they conserve more energy even under extreme conditions.
MoS2 Energy Conserving guarantees:
Significantly less fuel and oil consumption.
Significant wear reduction, fewer breakdowns and emergency lubrication properties.
Stable to aging and stable viscosity.
Good cold-start behaviour and high operational reliability.
Prevents sludge formation.
Tested on catalytic converters and turbochargers.

LubroMoly 2001 Ventil Sauber (Valve Clean) 150mL
Removes carbon deposits from valves and combustion chambers. Especially important in the mid-1980s LH injection cars that had a high build up of carbon deposits on and around the valves. It also helps protect the fuel system against corrosion and icing. Great for both injected and carbureted cars, and is safe for catalytic converters and turbocharged engines. Just add a can to your full gas tank. Repeat every other oil change for best results.
Cleans the fuel distributor and injectors, improving starting, idle, throttle response and mileage. The improved injection pattern and more precise control of the injected fuel quality means that the engine burns cleaner and uses less fuel. Also, driveability is improved: easier starting, less stalling, smoother idling, better throttle response, no run-on after the ignition is shut off. Add a can to a full tank of gas and repeat every other oil change for best results.
Long life 100% synthetic non-silicone-based brake fluid for hydraulically actuated brake and clutch systems
All types of hydraulic-actuated brake and clutch systems in accordance with DOT 5.1, DOT 4 and DOT 3 manufacturers' recommendations.
STANDARDS
FMVSS 116 DOT 5.1 NON SILICONE BASE & DOT 4 & DOT 3
SAE J 1703
The high wet boiling point 185°C superior to DOT 4 and DOT 3 fluids enables use of this product longer.
The wet boiling point is representative of the fluid after one year of use.
Specially designed for anti-locking brake systems (ABS) :
The viscosity (820 centipoises at -40°C) is much lower than DOT 4 (up to 1800 cp) and DOT 3 (up to 1500 cp) brake fluids. This allows for much faster cycling of the micro-valves and reducing stopping distances.
Perfectly neutral with seals used in braking systems. Anti-corrosion.
