should be 10W30. had problems when 5w30 was in mine so i made the switch and problem solved.
The oil capacity of a 2004 Volkswagen Golf 2.0L engine is: 4.7565 Quarts/4.5 Liters This is the total volume of fluid the engine will hold after a complete evacuation of the system including changing the oil filter out.
5W-30 is the preferred oil viscosity
no oil
about 4qts
4.2 qts
The 5 and 30 refer to the relative viscosity of the oil when it is cold (5W) and when it is hot (30W). A 5W-30 oil behaves like a 5W thin viscosity oil when the engine is cold, and it behaves like a 30W thicker viscosity oil when the engine is hot. A very thin viscosity is undesirable in a hot engine. In very high temperature situations, an even higher viscosity range, up to 50W, might be called for. Always go by the engine manufacturers recommendations.
what is the perfect oil engine for my golf gt 1989 1.8 8v ???
The wrong viscosity of oil in your engine.
5W30
10w 40
30w
The viscosity of the oil may not be heavy enough to protect the engine.
