I recently bought a new Scion xA for my wife as a daily driver. At 500 miles I changes the oil out for Mobile 1 5w-30 and a Pure 1 filter. The engine was silky smooth, and pretty quiet for a four banger. I was getting ready to change the oil again at 5200 miles when my wife pointed out that Scion offers the first three oil changes for free! Here is the dilema...
We took it in for its change. They used a Toyota filter (ok with this) and Valvoline 5w-30 oil (here is the problem). At first I thought we would just change it out right at 3000 miles and have no problem. That was before I drove it. The engine is now noticably louder and produces more vibration.
I asked my wife what she thought of the service as she had taken the care in. She commented that all the guys were really nice, and went on about how great she was treated, and then through in something extra. She asked my why her little baby was a lot louder and buzzed more. Now remember she is car-illeterate, and doesn't know much beyond put gas in and go. So, at least I know I am not the only one who noticed this.
My question is...is there something I could add to the oil to get the benifit of the free oil changes that would help me feel better about the add pack in valvoline, and as a side, maybe quiet down the engine a little. Otherwise I may have to skip the last three freebies, and go back to Mobile 1. I remember some little Valvoline or STP or similar that was actually worth something according to the guys on this site, but I can't remember.
Ps. I would like to be able to find it locally and easily.
