Theoretically speaking, VW 505 00 oil is an older specification primarily designed for early Volkswagen TDI diesel engines. However, its influence continues to impact modern global oil technology et maintenance decisions to this day.
In online discussions on platforms such as the popular TDIClub forum, Redditet Quora, there’s an old thread about VW 505 00 oil vs 505 01, where many experts and enthusiasts explore the subtle (yet crucial) differences between VW 505 00, VW 505 01et VW 502 00. This isn’t merely a matter of numbers—it concerns chemical composition, protective performance, and precision engineering.
TERZO, as a global lubricant brand that produces oils compliant with OEM standards, deeply understands how standardized maintenance safeguards diesel engine performance. For professionals, technicians, and dealers worldwide—in regions such as Asie du Sud-Est, Africa, North America, and South America—mastering these standards ensures selecting the right oil for the right engine.
VW 505 00 Oil Definition and Application
VW 505 00 is a Volkswagen Group oil specification for indirect-injection diesel engines et early direct-injection (TDI) engines without pump–duse (PD) or unit injector systems. It ensures proper wear protection, soot control, and oxidation resistance under moderate oil drain intervals (typically 10,000–15,000 km).
It signifies an oil capable of handling moderate soot loading and wear control, ideal for markets where older TDI engines remain active—like in Nigeria, Malaysia, and Central Asia, where robust, easily serviceable engines dominate the market.

VW 502 00 vs 505 00: Petrol vs Diesel
Here’s where many users—and even technicians—get confused.
In the TDIClub forum, one common misconception appears repeatedly: “Can I use VW 505 00 in my gasoline engine?” The short answer: No, and here’s why.
VW 502 00 covers high-performance gasoline engines, focusing on high-temperature deposit control and oxidation resistance.
VW 505 00, by contrast, addresses diesel combustion challenges, like soot suspension and valve deposit control.
Mixing them isn’t catastrophic, but it compromises efficiency and emission control.
For modern fleets, matching the engine family with the correct VW specification is not optional—it’s precision maintenance.
TERZO's Specialsynth 0W-40 et Supersynth 0W-40 both meet VW 505 00 and 502 00 dual-spec requirements, offering distributors flexibility for mixed fleets running both gasoline and diesel Volkswagens.

Choosing between VW 505 00, 505 01et 507 00 depends on the engine generation et regional fuel quality
For distributors serving mixed fleets, stocking both 505 00 and 505 01-approved oils ensures compatibility and customer trust.
Even as automakers move toward electrification, the diesel segment in emerging markets continues to rely on these established VW oil standards.
Real-World Application: What Technicians Say
From TDIClub discussions to real garage experiences, here’s what professionals observe:
“505 00 oils are perfect for older 1.9 TDI engines—just don’t use them for PD engines unless they’re dual-rated 505 01.”
- TDIClub user DieselGeek
“We’ve run fleets on 505 00 spec oils for years—good cleaning ability, no sludge, and smooth idle.”
- Independent service manager, Nairobi
Such feedback reinforces that VW 505 00 oils remain relevant—especially in markets where older-generation Volkswagens and Škoda diesels still thrive.
Not recommended; use VW 502 00 instead.
It’s superseded by 505 01/507 00 but ideal for older TDIs.
Only if the oil is dual-rated for both.
