What is the recommended VAG oil change interval in Bulgaria?
You'll hear plenty of conflicting opinions and recommendations on this subject. But you and I aren't here to waste time talking nonsense or kidding ourselves. We're here to work out what's best for your car and your wallet.
If you drive an Audi, VW, SEAT, Škoda, Porsche or Bentley in Bulgaria, the LongLife oil change interval of 30,000 km simply isn't suitable. And chances are, you're not replacing your car with a new one every year or two, as some German owners do. Not 15,000, not 20,000, and certainly not 30,000 km. Change the engine oil and oil filter every 10,000 km or once a year, whichever comes first, regardless of which oil you use! Leave those LongLife intervals to countries such as Austria, Germany and Switzerland. Wondering what makes them different? The answer lies in much better driving conditions and longer journeys from A to B.
Which engine oil and filters should you choose?
There are thousands of products on the market. Personally, I favour genuine parts and consumables because I believe nobody knows what's best for your engine better than the manufacturer that built it. To me, that's the most logical choice for all of us. The trouble is, not everyone can afford to avoid making compromises when it comes to their car, so they turn to aftermarket alternatives.
Here's my answer:
- If you can afford them, choose genuine parts and consumables.
- If your approach is to save money on servicing, save a little now and pay for an expensive repair later.
Whatever you choose, remember that everything comes at a cost. Sooner or later, you'll pay for it. The real question is whether you'd rather spend more upfront to save money in the long run, or spend less now and then...
Which VW oil specifications should you know before choosing engine oil?
VW 500.00
A Volkswagen specification for multigrade engine oils for petrol engines, with SAE 5W-X / 10W-X viscosity grades. This specification applies to engines manufactured before 2000 (up to August 1999).
VW 501.01
This covers conventional engine oils suitable for certain VW engines manufactured before 2000, much like VW 500.00.
VW 502.00
An oil specification for petrol engines that supersedes VW 501.01 and VW 500.00. Recommended for engines operating under demanding conditions. It must not be used in engines with flexible service intervals or engines requiring a different oil specification.
VW 503,00
An oil specification intended for VW petrol cars with WIV (LongLife service intervals). It also meets the ACEA A1 specification and is available in SAE 0W-30 or 5W-30 viscosity grades.
VW 503.01
This specification was developed specifically for models including the Audi RS4, Audi TT, S3 and Audi A8 6.0 V12 with more than 180 bhp. It has since been superseded by VW 504.00.
VW 504.00
The VW 504 00 specification supersedes VW 503 00 and VW 503.01. Oils meeting VW 504 00 are suitable for engines that comply with Euro IV requirements.
VW 505.00
This specification is intended for diesel engines. It meets standards that specify a maximum evaporation loss of 13–15%.
VW 505.01
This oil specification is used for certain common-rail engines. It is also used in some turbocharged V8 engines.
The viscosity grade is SAE 5W-40.
VW 506.00
These oils are suitable for diesel engines with extended service intervals. The viscosity grade is SAE 0W-30.
VW 506.01
This oil specification is designed specifically for Pumpe-Düse engines. It is a low-SAPS oil suitable for Euro 4 engines and almost all VAG diesel engines manufactured after 2000.
VW 508.00 / 509.00
These specifications (508.00 for petrol engines and 509.00 for diesel engines) cover oils with a 0W-20 viscosity grade. The oil contains a high concentration of additives designed to improve engine efficiency. It was first used in VW / Audi 2.0 TFSI 140 kW and 3.0 TDI CR 160 kW engines.
How do you choose the right workshop for an oil change?
What looks like a straightforward job can turn into a nightmare for you as the owner. What do I mean by that? Modern vehicles have specific servicing requirements, such as tightening different components to the correct torque in Nm using a torque wrench. On engines with timing chains, there's also the requirement to fill the oil filter before starting the engine. If this isn't done, the chains can run without proper lubrication on the first start-up and may jump timing, leaving you with an engine that needs major repairs. Then there's the need to prime the fuel filters on diesel engines. Get that wrong, and the high-pressure fuel pump can start shedding metal particles, potentially damaging much of your engine's fuel system. These are just some of the seemingly 'minor' mistakes a workshop can make during an oil change, and they can cost you dearly. That's why my advice is to ask plenty of questions before leaving your car with a workshop, even for a job that seems as simple as an oil change. Find out whether the people working on your car actually understand what it needs. Pay attention to how they respond. Do they brush off your questions or take the time to explain things properly? Do they offer genuine parts and consumables, showing that they care about your car and want to look after it properly? Or do they immediately suggest a cheap alternative because, to them, you're just another customer who's come in for a service?
