Buzzed The Net

The other day i was on my way to get my oil changed at walmart. And the day befor that my car was making a very funny puttering noise. At 1st i ignored it but after a while it got annoying. So i was on my way to get my oil changed thinking it might just be the oil. And it turns out it was from the oil but it was cause i did not change it in 6k miles. So i get there to change the oil and the car dies. I could not start it back up so i got it towed to find out it is dead for ever. It was probaly from me not changing the oil for about 6k miles. It was my 1st car so im not to mad accept for the fact that i just got a new car system put in.
