Good to have period information like the Felicia Workshop Manual dated July 2000, I note the "Ausgabe 01.98" at the bottom of the page which in English manuals usually/often means the original issue date of the information but  I would never be certain about what VW mean, Google translates ausgabe as output.

 

IF "Ausgabe 01.98" means issue date then the information is from 25 years ago.  I find information from when the car is new is usually a very good starting point and often the best finishing point but not always as things change and sometimes there are improvements.

If they were both 10w-40 then my apologies, there are far to many posts on oil for me to remember the details (and yes I have contributed a lot too).

As for your VW colour chart my wife and I are in trouble as my wife's VW/Skoda had the VW/Skoda Dealership carry out the annual service this September, (this time is was the 8 year/80,000-mile service) "to manufacturers specification" using 0w-30 engine oil and even in England we have outside temperatures of above 60f/15.6c, in 2022 locally we had 40.2c (104.36f).  I will have to tell my wife we can only use the car for short periods when the outside temperature is above 60f/15.6c, that should save a bit on petrol expense if nothing else.  Religion (including sports), politics and figures are always highly debated.  🙂

I wonder a 5W-40 engine of 1998 era is the same with one from 2022-23?

For example who knew ENEOS oils in year 1998?

You would have to ask the particular oil companies, possibly there is also a wider range of 5w-40 oils now as consumers simply must have more and more choice of consumables.

 

I didn't know of Eneos until now let alone 1998!  😄

 

If you have not already done so read the articles from a link put up in that Cz Skoda Felicia forum thread but bear in mind the articles are simplified (and to my mind generalised), they are from 2004 publication, pity part four isn't linked. -

Don't get too carried away with numbers, and what ever numbers you see you need to consider how long these numbers might remain when the oil is in active arduous use over a period of time in the engine.  If you want to carry on with the numbers games, after reading the articles above then perhaps have a look at the following link and/or any articles you find yourself, for information the internet world is your oyster.  😄  - https://www.q8oils.com/energy/viscosity-index/

So it seems that many more oil can be run but 10w40 is a no go for more than 20c environmental temp

Actually you are reading the diagram wrong. Yet, you have the excuse of trying to read a difficult/confusing diagram. Not sure who was the genius who drawn that mess, but you can't draw two or multiple viscosity engine oils into one single temperature interval.

When I say "temperature interval" I refer to the minimum and maximum temperature for a given oil where its viscosity allows easy engine starts and decent lubrication.

A better understanding of optimum temperature intervals function of the SAE number is the one below.

 

Also bear in mind a "thin" (for want of a better word/description) say 50 or 60 could drop to the 40 or 50 band with use.

 

Thank gawd for that chart, I don't need to try to restrict my wife's use of the car, well as long as it's below say a chart 37.  😀

I don't like your chart, for my wife it's dropped the about 37 to +35°C.  😒

What's the difference between those 2 charts? Green (Owners' manual) and Grey (Workshop manual, so called the ''latest").

There is no ''update''.

 

On the other hand, Skoda at 1998 told us about Halogen bulbs, didn't knew that some years after we could install HID and LED bulbs with much better performance in the same front light (which was designed for Halogen bulbs).

Do you beleive the Skoda chart that the 10W-40 is only for 15 °C ambient only?

If that was true all the Skoda felicia in Mediterranean area would be blown.

Very useful.

Keep in mind that Castrol here in Greece has the worst name because many e-shops sell counterfeit Castrol semi-synthetic oils.

When we see cheap Castrol we say it's ''monkey'', there are videos how to spot a fake one.

As for the ''we buy engine oil from one compnay and we add additives and sell it with different brand name'' it's common here with Gasoline.

Some companies buy from here https://www.helpe.gr/the-group/products-and-services ,then add their own additives and sell it in gas station with their own brand name.

Also the 95 octane becomes 98 or 100 or Racing accordning to the ''recipe'' of each company, the basic 95 octane gasoline is the same for all of them.

The diagram is made to confuse the hell out of people. To me it is useless, and the single reason I posted the "last version" of it is that you mentioned my initial diagram was issued before your owner's manual edition.

So rest assured that what you know about oil engines now is enough to allow you select the best engine oil for your car.

 

My conclusions about this (futile) endless topic are below. They will allow you to choose the perfect compromise for your engine lubrication.

• First, you have to respect the PERFORMANCE LEVEL recommendation of the manufacturer of the engine oil. In our case, it is the VW standard.
• Then you have to choose the SAE viscosity grade (xW-y) of the engine oil
• x refers to the viscosity grade at lowest, constant winter outside temperature (WOT) in your area. An empirical formula is this: x = WOT + 35.
• y refers to the viscosity grade when the engine is running at its optimum temperature (roughly 100°C). Since Felicia has not an oil radiator to compensate for high engine loads and high summer outside temperatures (SOT), y must be correlated with SOT. Again, an empirical formula is this: y = SOT.

That is about it. I would not beat this subject to death or lose sleep for scientific details. If you want to keep your Felicia engine happy, drive it without beating it to hell and change your engine oil as often as your pocket allows. Remember you are not driving a rally car, but a small family car which put a smile on our face for being reliable, easy and cheap to maintain.

 

Here is a video that explains what I wrote above in more detail.

I wonder: those 2 different Felicia owners must use the same engine oil?

I'm not for or against Castrol oils (in the UK Classic Castrol Oils are marketed by the MG Owners Club) and you can't blame any manufacturer or blender for people buying counterfeit products from dodgy suppliers just because they are at low prices.

 

Personally I would not worry about VW's dictates on an old design of engine like what is in your Felicia unless I'm told VW done a lot of improvement work on manufacturing and building the engine, the quality of Skoda dropped when VW first started taking over but by the end of the 90s I expected things would have improved as VW quality then was not as it was into the next century and now.  And VW superseded the specification numbers anyway, I guess later engines the oil additives packages may well be required to help squeeze the last nth degree out of such ancient technology as the internal combustion engine and perhaps help with engineering requirements from compromised development and build of those engines.

Those 2 are for Felicia.

 

VW 500 00: 

Volkswagen specification for multigrade mengine oils for petrol engines with SAE 5W-X/10W-X viscosity. This is an "old" oil specification and is applicable to engines built before model year 2000 (up to August 1999). Oils with an approval made post March 1997 were given an alternative, later VW specification.

VW 50101: 

Conventional motor oils suitable for some VW petrol engines built before MY 2000. This is an “old” oil specification and is applicable to engines built before model year 2000 (up to August 1999). Oils with an approval made post March 1997 were given an alternative, later VW specification.

 

 

All i said was that here i us, cheap Castrol oils from e-stores have bad reputation.

Yes I know, my wife has a VW product so I had to learn about the VW dictates and oil specification numbers.  With my wife's VW/Sskoda car the Owner's Manual (called "Operating Instructions" and the infotainment book is called "Owner's Manual" surely not a VW mistake) states the VW specification number of the oil required but not the multi-grade weight or refill quantities.

Yes and I put you can't blame any manufacturer or blender for people buying counterfeit products from dodgy suppliers just because they are at low prices.  Do you know of a counterfeit product supplier with a good reputation, other for bringing in money for themselves and/or the criminal gangs.  This is why it is better to buy from a good reliable legal source and perhaps pay more than the lowest price available.

 

There was no English language option on that video but I don't buy Castrol off dodgy e-shops so I am not too concerned - not that, I guess, counterfeit products have not made their way into garages over here, a lot of very dodgy characters work in the British motor trade.

 

''Chart-o-mania'' or ''Give Chart to the people''.

 

I have lost the account from oil viscosity charts, anyone publises anything he wants about engine oils.

Take a look 2 examples, look the 5W-40.

At last "the penny drops".  With whatever chart, or other information, you have to look at the parameters, scales, testing system/specifications and ranges and allowances and the source.  A better product may be able to go further than a lesser product and for longer and less wear, meeting more than the minimum standard.  Like the UK MoT, it's a minimum statutory standard that must be meet once a year, at one point in time, much of it to one trained person's opinion, a pass does not mean the car is good in other ways and only that it meet the points I put. before and not necessarily better than the minimum standard required.

 

Now it may be the minimum or a bit above minimum is adequate for your wants and needs and those of the majority or vast majority of your vehicle model owners or you can decided differently if you want/need, it's up to you and you know you have lots of choice with oils and now so much information that you may feel you no longer know, as we say over here, "your arse from your elbow" but I am sure, as The Beatles almost sang, you can work it out.  You will come to your own conclusion.

 

"Enough already" with the charts, they have served their various purposes.  😁   

While waiting for the next engine oil change (from Synthetic 5W-40 to 10W-40) i post some photos in that non futile  and thankfully endless  topic.

For first time in the latest years the fuel consumption is getting Lower (same route in city traffic).

 

 

 

 

 

As the weather is getting Cold the fuel consumption will lower more, i will post some photos as a prove.

As the weather getting worst the fuel consumption is lowering !

 

 

 

 

 

 

 

 

 

Not good quality photo but it was night and i had no time.

 

 

 

 

As the ambient temperature start rising a bit the fuel consumption followed, one click ''worst'' than Cold weather, i will post some photos in my next post.
