The 200,000+ km thread

I used to use 5W30 , fuel efficiency was better but the 5W40, I see handles heat better and does not get as hot as the 5W30. I also noticed since using the 5W40 the chain rattle o start up is now quieter and I only get the rattle maybe once every 6-7 start ups most times its starts up silently. just my observation i have no scientific data to back it up.

The car was on the alignment bay and I did a walk around under and all 4 shocks are dry .

I’ve also been thinking of 5W40, what VW spec is your oil? I’ve never seen oil temp over 101c though.

I personally use Liqui moly Molygen - that bright green one, no issues , I do use the VAG spec VAG spec 502 if I cant get Molygen but be aware 502 can only ne used if you dont have a DPF - Mine is gutted, just the housing is in place.


On a warm summer day coming up van reenens on 5W30 I got up to 107c with 5W40 I get a max of about 102c - we talking ambient temps of around 30c or more

Liqui Moly Molygen New Generation 5W-40 is formulated for Volkswagen Group vehicles. It carries official factory specifications for older and non-DPF equipped VAG models, specifically meeting VW 502 00 and VW 505 00 requirements. [1, 2]

Key VAG Specifications & Features

• VW Approvals: VW 502 00 (gasoline engines) and VW 505 00 (diesel engines without particulate filters). [1, 2, 3, 4, 5]
• Molecular Friction Control (MFC): Utilizes tungsten and molybdenum additives that are shown to reduce engine friction and wear compared to standard oils. [1]
• Leak Detection: Features a bright green, fluorescent UV dye that glows under a blacklight, making it easier to trace and diagnose oil leaks. [1, 2]
• Viscosity Data: 14.5 mm²/s at \(100\text{ }\text{\textdegree C}\) with a high-temperature high-shear (HTHS) value of ≥ 3.5 mPas. [1]

Local Sourcing & Compatibility
Always verify your exact vehicle's owner manual to ensure your engine requires VW 502 00 or 505 00. Many modern VAG vehicles with TFSI/TSI engines require stricter low-SAPS specifications (like VW 504 00/507 00), in which case you might opt for oils like Top Tec 4200. [1, 2, 3]


One more thing to remember if you change the weight of your oil , you will notice that the engine revs up slightly and i am talking very slightly longer but your fuel usage will get about 1 to 2 litre per 100km higher - here you will ave to weigh your options - better protectin vs fuel mileage and engine speed is very minimal difference but you will notice its running thicker oil
