Mobil 1 oil change and effect on acceleration

georgesti · 01-19-2004, 04:35 PM

I just changed my oil for the first time at 1500 miles.
I reaplaced the oil with Mobil one 15w50, and used a Fram x2 filter.
I noticed after i replaced the oil the shifting was much smoother and when i push the engine the revs somehow seem less harsh, its a little hard to explain but the accelration seems smoother, I'm wondering if using a synthetic oil can in any way effect accelration.

I dont know if i am just looking for sometihng or if the accelration really is different? Also is the oil i used alright for the sti?

thanks for the help

Yes, you can make slightly more power as well has have better mileage w/ synthetic oil.

As for whether that particular oil is the right choice, I'm not sure... i don't think 15w50 is the right oil though....

I use Mobil 1 5w30 and as far as I know the manual calls for this but I might be wrong.

Also, some forum members have said FRAM filters are POS.

Well then no problem, i live in San Diego. and i got the X2 filters from fram, i guess they are considered their premium filters.

Oh well next time ill go for bosch if i can find them at pepboys or autozone.

at least your running a new filter. i actually came across a guy who thought he was saving himself money by just changing the oil and not the filter. anyhow, most filters tend to be as good as the next, as long as you avoid the super cheap ones that some auto part places sell.

One guy on clubwrx spun a bearing because he used a FRAM filter. How you say? Well the filter broke a part and it clogged up the oil lines. Scary stuff to save 2 bucks.

Dude - I would use the factory filter (P/N 15208AA080). You can buy them for fairly cheap from http://www.allsubaru.com/ $32 and change for 6 of them.

wow thats a good deal, ill probably use that for the next oil change.

My fram filter was $10, so i didnt go for the cheap option.

Oh yeah, don't forget the crush washers - all subaru also has those (they are just a service dept at a dealership really). Just give them a call if you have any problems locating them on the web site - they are very helpful.

ya Allsubaru with subygal are VERY NICE, they will hook you up with a set of filters and their service is great.

I may be a little paranoid, but I think the best way to protect yourself in the event you ever have a warranty issue with the motor is to buy the oil filter from dealership and maintain file with documentation.

I just ordered the filters. $32 for six filters! :eek: Very good deal!
