I thought Audi always used Castrol. It could be because they are also a Porsche service center, and porsche only uses Mobil 1.

I thought I remember seeing something that people thought Mobil 1 didn't work well in our engine. Whats the general consensus?

thanks

except for Shell V-power gasoline.

I wouldn't say that's a general consensus, though.

I only have 4500 miles with an oil and filter change at about 2900 miles. For those who drive 1000+ miles/month and/or track their cars and/or plan to keep their cars beyond a couple of years there may be better choices than either Castrol or Mobil.

We have one oil sample on a car that has 17K miles on it, and it doesn't compare well to other oil samples on engines with similar mileage. I'd like to see one or two more M1 samples before I make a definitive statement, and say that the oil is pure crap in this engine.

Care to have Terry Dyson analyze a sample in 3K miles, and see what his recommendations are?

Bob, do you plan on taking a before and after video clip of your car's exhaust note?

If you can't trust the designers of the car, who can you trust?

what's so strange? it would be strange if every Audi dealer used Castrol. possibly you've been listening too much to some people on the A4 and S4 boards.

this is an issue which has not been satisfactorally addressed yet(i.e. drawing conclusions on a couple tests). any conclusions, either way, won't fly.

choose your own oil based on the info out there, past preferences, recommendations, whatever. just keep it in proper perspective.

for example, here in KY, we have Ashland Oil manufacturing facilities (aka Valvoline) so our dealership uses that as well as many specialty blends on local racing teams are tried here locally. Interestingly there are some neat oil studies done over at Ashland and with their sponsored teams that come through.
