increased performance after first oil service?!?

booth · 11-12-2010, 01:59 PM

hey all, i have a 09 335i, love the car, took it in for its' first oil change aka "oil service" this past weekend after putting on roughly 8500 miles in the past 14 months. i've noticed that the car is noticeably faster. is it me or does anyone else notice this? wondering what does this, if there is some computer limit until the first oil service, or what.

i love the new speed, will try to get some performance tests in the near future.

09 335i stock 0-60mph in 4.9 seconds 6 speed automatic DS mode (with a full tank of gas too)

P.S. i also get variable performance, some tests will be 5.2 seconds. seems like the turbo has a mind of its own.

What are you recording those times with?

booth · 11-12-2010, 02:18 PM

I use an accelerometer so yeah not as accurate as other options, have a wire and software but use a mac, so haven't been successful at hooking the computer up to it yet.

Delta0311 · 11-12-2010, 02:24 PM

No your "stock" times are about right... Is your car E90 or E92?

booth · 11-12-2010, 02:33 PM

not sure, will look to see if i can find out. its 09 335i

galahad05 · 11-12-2010, 02:35 PM

Is it a sedan or a coupe, is what Delta was asking.

booth · 11-12-2010, 02:39 PM

its a sedan

2kaccordocoupe · 11-12-2010, 02:40 PM

maybe they updated your software while you were in for service?

booth · 11-12-2010, 02:41 PM

i think that they did, although am wondering if anyone else experienced this. i guess i have the e90

nice

can't wait to get it on the road, i live in a city, so kind of hard to drive it like it wants to be driven

Its because got your oil changed!!! I am not a fan of your BMW computer telling me when its time to change my oil. You spend 50k or more on a car and your trust BMW engineers when you should change your oil. LOL can you say mistake? Remember these are the same people that can't figure out HPFP problem. Do yourself a favor and change it every 5k or 3 to 6 months. I do and my engine thanks me by getting better gas mileage and running way better.

hipnotic · 11-12-2010, 10:20 PM

probably update software

bmwpride335i · 11-13-2010, 01:57 AM

What oil do you guys use or, what would be a good oil brand / grade to use when you do oil change on your own?

Spydeputy · 11-13-2010, 04:52 AM

OP, look at your service ticket, it will say what they did.
If there were no changes made I suspect it is your But Dyno telling you the car is faster.
It's not coming from having cleaner oil, less friction.
Oh, and I strongly recommend you change the oil between what the dealer is doing,
if you plan to keep the car past it's warranty.

CBS told the dealership to change my oil after 1800 miles, August to November. As they say, monkey see, monkey do. Now, when you look at service info, the next oil change is 16,000 miles away.

I'll change it 7,500, but to tell you the truth, with a dealership having a $59.95 coupon, I don't think DIY is worth it, and plus I'd rather have a record of the interval change while I have the BMW extended gold.

maybe they updated the software which reset the AT map.

since you are past breakin and no longer holding back, its probably put the car in a more aggressing mode
