I got my oil changed today at a new place. I had just read a thread that mentioned that my car (07 sti) actually hold about 4.8 qts instead of the factories suggested 4.3/ 4.4. I mentioned this to the guy. He looked at his computer and said 4.3. upon my return he mentioned that the put in 4.3 and it was still reading low so they went up to 4.8...still low. He then said they put in a full 5 quarts. I also just switched to mobil 1 5w-30. Does this extra ol present any problems like blown/ leaking gaskets etc. Also, kind of strange the car seems a bit sluggish when turning at low speeds. I have the Differential set in manual all the way back or locked out. It didn't seem this sluggish before. Any suggestions/ideas?

I suggest you check you dip stick. Putting in 5qts shouldn't kill you. But if it's over then you'll want to let some out. I put in 4.5 everytime. Oh, and I suggest you learn to do your own oil changes.

Yes, definitely learn to change your own oil, not only does it save you cash, you also learn about your vehicle.

You shouldn't have to worry about having 5 qts in, but the manual does say 4.8 with filter and 4.2 without filter I believe if I remember correctly. You should be fine with Mobil 1. I used it for my first oil change. I have an 07 also. Everybody has their personal preference whether it be by brand or benefits. The sluggishness at low speed is probably because you have it locked out, with AWD vehicles one tire turns faster than the other making that feeling when turning.

I usually do my own oil changes. This place had sent out a gift certificate for a free oil change(in an attempt to gain new clients) I leave it locked out most of the time and it hasn't felt like this. I'm going to call them today.

Ok, Now I'm sue somethings up. The cars seems slower at high speeds. Took it out for a run and just seems sluggish when you get on it especially in 3rd gear and up. Do you guys think too much oil would slow it down. Either way i am taking it in tomorrow and making them drain some out.

.2 L oil is nothing to be concerned about.

I also just switched to mobil 1 5w-30. Do you think that could have anything to do with it? The acceleration just doesn't seem as brisk. I spend a lot of time in the car(4,000 miles in august alone) and pay attention to how things feel. I know a lot of people run 4.5 qts do you think thats enough to make a difference .5 ? I don't want to risk blowing a gasket or forcing a any leaks.

Then drain .5 quarts and go on with life. I think it may be in your head. If you want to be completely sure do another oil change on your own and you know exactly what will be in there then.

i always put 5 quarts in my car and i do my own oil changes. ive ben doing it this way since day 1 and now im at 67000 miles with no problems. i only do this because anything with a turbo (even brand new), that is driven spiritidly somewhat often is going to burn oil. thats just the nature of the beast. now i wouldnt go putting anything over .5 quarts in it. a whole extra quart may cause some problems.

mobil 1 5w-30 is good oil thats surely not your problem. i run 5 quarts of it on my oil changes

[EL Capitan]

Well, this is all reassuring. The car is going to get a good workout tomorrow and sunday. hopefully I will burn some of it out.
