What does her owner's manual say to use? I'm assuming this is a factory car with a factory turbo in which case the Manufacterer will have it's recommendation of what weight/viscosity of oil to use.
Compare that to what they are trying to sell her and determine if they are "upselling".
I've dealt with this plenty of times when going to a big box parts store or oil change place. I'm convinced they keep some old, crappy worn out PCV valve laying around to show people there's is "bad" so they can sell them a new one.
I used to play around with them and change the air filter and PCV valve before going in for an oil change just to see what would happen. Sure enough, one came back and said I had a bad PCV valve and showed be this old oily looking thing they "pulled out" of my car.
I told them that's funny since I personally just replaced it with a brand new valve the day before. They shut up and didn't mention it again and I never went back to that place.
And don't get me started on the counter jockies at the parts stores that try to sell you a spark plug with 100 ground straps attached to it and cost $50.00 each saying they'll give you 5HP.
