Mineral oil will hardly meet VW specs if they specify Full synthetic, would it????????Quote:

Use an unapproved oil at your peril if something goes wrong.
Get it in writing what they are doing.
To the best of my knowledge, there is no mineral oil that will meet the minimum VW spec (502.00) for that engine.
If they do change the oil, get written instructions on how they want the car driven to facilitate the bedding-in process & also when they want you back for an oil change.
There is no way any mineral oil will be good for 15,000km or even 7500km in that engine - I would go 3000km at the very maximum.
Tell them straight that you've lost confidence in the product & the dealerships ability to provide a permanent solution to the oil usage issue.
Haha that's a good one! Mineral oil that meets VW specs. Sorry couldn't help but laugh.Quote:

502/505 as far as I know can be a blend of mineral and synthetic oil or full synthetic in various grade but never heard of a VW spec oil made from pure mineral oil - specially with Europes strict emissions regs and Europes weather.
By all means do what the dealer says after all they are doing your warrantee work but I would be asking for a officiall letter like brad said - again I don't expect them to give one to you.
I don't mind admitting when I'm wrong.
Penrite HPR30 20w60 is 502.00 & full mineral. I wouldn't run anything that thick in a modern, unworn engine
HPR Diesel5 5w-40 is 502.00 & semisynth You could get away with this.
There must be others
So are you saying that they are correct in implying that they have a mineral base oil at the right specifications?Quote:

Neither of those two are on the list of APPROVED oils I have. Buy some Penrite Enviro+ And never be wrong About $69-$79 at SupercrapQuote:

Oils approved to VW standard 501.01 can be met using a mineral base and often have viscosity grades of 10W-XX, 15W-XX or 20W-50.Quote:

If the dealer goes ahead with its plan, they would be overriding the original factory recommendation.
For the record, the owners manual for most VW vehicles suggests driving at moderate revs and loads during the first few thousand km - even for the Audi R8, with its 309 kW 4.2 L V8 using either 502.00 or 504.00 oil.Quote:

After 5000 km, the engine may use up to 0.5 l per 1000 km before it is considered excessive.Quote:

Penrite claims that both products are able to meet 502.00, but neither product has been tested by VW for approval - so your claim that there are no mineral 502.00 oils can still stand.Quote:

Shell Helix HX7 10W-40
To my knowledge, no engine oil that has VW 502.00 approval is made from a mineral base (in contrast to VW 501.01)Quote:

I also use engine flush from Amsoil and VW engine flush once each. 5000km or 3 months drain interval after the run in is completed. I only get oil lost of around 100ml every 5000km. I used to have higher oil lost of 200-300ml with other types of oil. My previous Hondas all started burned oil after 20,000km as I was ignorant about warming up the oil temp and uses water gauge as an indicator just for info.
Yes you are. :)Quote:

The early oil changes are important to me too.

The VW and other car manufacturers were wrong with their service recommendation so may times, so why on earth I would take their word for it that the engine will be fine when it gets the first oil after 15,000km/12months? You can't save the planet while changing the oil once a year or even every 2 years, you will just pollute it more because more engine/parts/cars needs to be made. Just look what's going on with the transmissions/gearboxes that are filled for life? :facepalm:
The others have answered for me.Quote:
