VW 505.01 was developed around the lubrication demands of pump-jet and unit-injector diesel engines, making it particularly relevant to the camshaft-driven injector system used by the TD5.

Find the right VW 505.01 engine oil
Ravenol VMO 5W-40 is the main Twinwoods choice for normal TD5 servicing, remapped road engines, towing, off-road work and other sustained-load use. The same formulation is available in a 5 litre bottle for oil changes and a 1 litre bottle for topping up. Ravenol RUP is a more specialised racing formulation for highly tuned and competition engines.
