#7 of 26 Found the 502.00 certified oil I wanted
Jun 14, 2007 (5:09 pm)
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.
#11 of 26 some more info on 502 oil.

briskoda.net (add usual http://.www header to make complete) has a forum that discusses a number of oils for high performance VW and Audi vehicles.
The latest seems to be 503.01, which is specified for the Audi RS4, S3, and TTs' over 180 hp.
#12 of 26 Oil Change

I had my 25,000 mile service last week at my Audi dealer. A couple of days later I checked my oil level. It was at the midpoint of the dipstick. There was no leakage and I had driven less than 50 miles. I called the dealer, described the problem and they said that they filled the reservoir to the midpoint on the dipstick due to expansion when the oil was hot. I'm hoping Shippo is reading this because I really respect his thoughts on oil related questions. Is this correct? I've always "read" this as 1/2 quart low over my 62 years.

That's a load of bull. Yes, it will expand when heated, but, um, 1/2 a quart. No. Tell them, nice try, but you'd like the other 1/2 quart, thank you very much.

Yeah, the expansion thing is a bunch of BS. That said, virtually every manufacturer that I've looked at recently recommend filling the oil pan so that the oil level shows about half of a quart low. Why? Beats the stuffin' out of me. I routinely fill all of our cars with about a half of an extra quart when changing the oil, and they always show exactly full on the dip stick.

Thanks Shipo. One really odd thing about this, the dealer is saying Audi's instruction to him is to fill the crankcase to where the dipstick shows 1/2 quart low, while my owners manual tells me I should be thinking about adding oil when it is at the same level. There is a big disconnect here!
I've also done some more investigating and talking to Audi and the dealer's service manager. I'm now at the opinion that my oil was not changed. I bought a bottle of the same oil my invoice said was put in and compared the look of it to what I got out of the crankcase on the dipstick and on my towel. The crankcase oil seems darker to my eye. Also, my car wasn't washed when I picked it up. The practice of this dealer is to always wash the cars before presenting to the customer. Plus my tires were not rotated as I asked for them to be. Really makes me suspicious.
Also, how does one go about getting oil analyzed should the dealer not acknowledge any fault? I've searched the local places on GOOGLE and can't readily find a place which does this in the area.

A couple of points:
1) The color of oil has absolutely-positively zero correlation to its suitability for lubrication of the engine that its in. Said another way, it is entirely likely that oil can darken significantly after only a few dozen miles.
2) Very few of us live near a company that performs Used Oil Analysis (UOA). Most folks, me included, send our oil out for analysis, and many of those folks use Blackstone Labs (they'll send you an oil sample mailing kit for free). http://www.blackstone-labs.com
