I've asked 4 audi dealerships from SD to Oakland about which oil to use.
They all said mobil-1.

You can get a case(6) of mobil-1 from costco for $30!!!

I went to Wal-Mart at lunch time. The 5qt jug of Mobile 1 and Castrol "fully synthetic" goes for $20. Super Tech (previously and incorrectly mentioned by me as Syn-Tech) goes for $14. Considering what I'm protecting (mainly my wallet), I think it's worth the six bucks to spend for Mobile 1 and Castrol. I haven't checked yet, but I'm going to bet it uses more than 5qts of oil [:@]

 

I'd use one of the name brand synthetics. Maybe I'm a sucker for marketing, but an extra $6-8 a few times a yearsounds like cheap insurance when a turbo replacement is over 3 grand. (But I'm still using midrange gas because I haven't seen any performance difference and it adds us when you drive 1000 miles/week.)

I believe the 2.7T takes a little over 7 quarts.

 

PPGOAL...I agree. Cheap insurance it is. Also, you answered another question I've been meaning to ask. If anyone used mid-grade fuel. Unless you're on a track, I wouldn't think that it would matter much. In daily driving, I wouldn't think we'd really have to worry about carbon buildup or anything and that the turbos would work just fine. With this being my first turbo vehicle, I wasn't sure if it would foul up the plugs or if I'd develop a knock.

 

My uncle is a dist. for RP, and from what I have seen it is a good oil. I used to build oil testers for him and we would do demos and RP was the best performing. I haven't heard anything about it in awhile or really payed attention for that matter, but I remember alot of hype about HP gains, longer times between oil changes etc.... I know on his 1995 F250 diesel that now has 400K+ miles, he used to go on like 18,000 mile oil changes and would send off a sample to be tested and the oil was still good.

 

royal purple is without a doubt a superior product
ive been building race engines for years and have never seen motors look cleaner internally than with the RP

amsoil is my low cost solution as its readily available to me, seems to work better than mobil1
i have customers whos cars used a quart between changes, with the amsoil theres no need to top off at all
the mobil 1 seems to burn off at a higher rate than others which leads me to think the film strength isnt as high as the others

 

When looking for a synthetic oil, just make sure it meets the VW 502, 505 standards. I use castrol syntec in my 96 avant and it states on the bottle what auto manuf statdards they comply to.

 

Amsoil since 1993 for me!!

 

i have heard that you should not put synthetic oil into a car with high miles (mine has 147k)

is this true?

 

I've seen people use Royal Purple, perticulary my friend who has a Vr4. It works great on his car and also another one of my friends who has a sr20det 240sx uses Royal Purple, if its good enough for an sr20 motor i think it shouldnt have a problem in the Audi's motors. That said I still use Mobil 1 in my 2.7t. It just seems that this is the oil that is most commonly used and I never have had engine problems while on it so it has to be good. Royal Purple is expensive and hard to find compared to Mobil 1 so I stick with Mobil 1.
