Pentosin CHF 11S or an equivalent hydraulic mineral oil.

Brake Fluid:

DOT 4 or DOT 5.1.

Engine Oil Leaks:

Common leaks from valve cover gaskets, oil pan gaskets, and front crank seal due to age and heat.

Turbocharger Wear:

Turbocharger seals can wear, leading to oil consumption or reduced boost. Regular oil changes are crucial.

Cooling System Leaks:

Aging hoses, radiator, and water pump can develop leaks.

Window Regulators:

Electric window mechanisms can become slow or fail.

Suspension Bushings:

Rubber bushings in the suspension can degrade over time, affecting handling and ride comfort.
