#1 of 26 Motor oils for A3 and similar Audi/VW turbo 4s
Jun 04, 2007 (12:31 am)
Does anyone out there know of a synthetic motor oil brand BESIDES what Audi or VW wants to sell us at their dealers that matches what my '07 Audi A3 owner's manual specifies as the "Audi oil standard VW 502 00" (p.286)? I went to a chain auto repair store with quite a selection of brands and viscosities. NONE of those brands included meeting this VW 502 00 standard. Many did include standards for the most popular cars sold in the U.S., e.g. Toyota, GM, Ford, Chrysler. I wonder if the last three digits of the VW 502 00 is code that the oil be able to meete the high temperatures for engines with 200 or more horsepower? I bought Pennzoil's best synthetic 5W 30 since this new parts store didn't have the desired SAE 5W 40, which is Audi's first choice in viscosity AS LONG AS IT MET their "VW 502 00" standard."
Are there any code talkers out there?

Here is a link to a post of mine from last year that will unshroud the mystery of the VW oil spec codes:
shipo, "Volkswagen Passat Oil Changes & Issues" #8, 10 Mar 2006 9:48 pm
- Castrol Syntec 5W-40
- Pennzoil Platinum European Formulation 5W-40
For the superior 503.01 (meets and exceeds 502.00)
- Castrol Syntec 0W-30
- Mobil 1 0W-40 (my personal preference)
Hope this helps.

Shipp and Oil Man's rap is certainly of value and I'd tend to go with the oil higher rated than the 502 00, EXCEPT with what I've read about if there's a need to contest oil sludge issues in a VW or Audi, then it's perhaps best to show one used what was recommended in case things go to a court of law so that I can say "well, I used the oil that was recommended and had it changed at the recommended service intervals, so why are you (Audi or VW) giving me trouble?" Comments welcome. The Passat info. is of interest since I'm selling my '98 Passat to a friend (only 70K mi.), and I warned her about oils to use (synthetic, etc.). She knew better anyway because she was driving a Bimmer 5-series and knew of the sludge issue. Anyway, I posed the 502 00 question to the dealer's service dept. (Barrier Motors, Bellevue, Wash., a Seattle 'burb). Haven't had a reply yet, but thanks for the warning about a dealer substituting what Audi recommends for a less-expensive, more profitable oil. I may just go back to having my service guy do the changes with oil I supply. Where are you buying your oil? I go to a chain retailer auto supply store (Schuck's in the N.W.) I "near never seen that Yuro-pee-in oil" where I shop.

No worries about using the 503.01 oil in your car as BOTH of them are certified 502.00 as well. I have a copy of the VW/Audi Technical Bulletin dated 26-Jul-2005 regarding which oils are 502.00 certified, including (among many others) Mobil 1 0W-40.
If you want me to E-Mail you the bulletin, just look up my E-Mail address and I'll fire it right off.

Miramar Audi in San Diego, CA, uses 5W-30 Castrol Syntec because they say Audi recommends it for mild/warm/hot climates, like sunny parts of CA.
They claim the 0W-40 and 5W-40 is for colder climates?

"They claim the 0W-40 and 5W-40 is for colder climates?"
They do huh? If a dealership told me that about my new Audi I'd quickly be finding a new dealership as I'd never trust them to lay a finger on my car.
The fact is that 0W-40 will "out-winter" a 5W-30 AND "out-summer" that same 5W-30 regardless of the time of the year and the prevailing weather. Said another way, for your car that requires at least an oil that is certified to meet the VW 502.00 oil spec, there is no better oil for it than a 503.01 certified 0W-40 (a close second would be a 503.01 certified 0W-30).

I was mainly concerned with finding the proper VW/Audi certified 502.00 oil and didn't want to go to the dealers to buy it. I ended buying a quart, just as a spare for the car, from my mechanic I used for my out-of-warranty Passat -- for five bucks a quart, which I considered a deal. I can't recall the viscosity, but it met my needs that the manufacturer insists upon.

It isn't all that difficult to find 502.00 oil. Virtually every K-Mart, Walmart, NAPA and Autozone that I've been in recently has at least one of the following on the shelf:
Castrol Syntec 5W-40
Castrol Syntec 0W-30
Mobil 1 0W-40
The first is only certified as a 502.00, the last two are certified as both 502.00 AND 503.01 (which means they are MUCH better oils).

Care to enlighten us on how 503.01 is a much better oil? What makes it better? What characteristics and properties does it exhibit, what performance gains are achieved?

Scroll up to message number 2 of this topic and follow the link I posted to the VW Oil topic. In there is the list of applications that the various oil specs were developed for. Said another way, the engines with the highest specific output per liter, the highest pressure turbochargers, and/or the most mechanically complex are the only ones that require 503.01. What using the more robust oil translates to for someone who is driving a car that requires 502.00 is an extra measure of measure of shear resistance, an extra measure of heat resistance and greater level of protection against sludge formation (not an insignificant issue for VW & Audi owners).
Can I give you the specific benchmarks that VW requires for an oil to meet that lofty spec? Nope. I've looked and looked, and as of yet have been unable to find it. What I do know though is that oils based on Group III Hydrocracked Crude can be made robust enough to meet the 502.00 standard, however, not a single Group III oil has ever been stable enough to meet the 503.01 spec, that seems to be a realm where only fully synthetic Group IV oils need apply.
