I found Lightning Lube on Yelp when I first moved to the area. I know nothing about fixing cars and I was coming off a 1600 mile drive in moving from Portland to Phoenix, so I needed an oil change.
I tried them out because of their reviews and I'm glad I did. They are friendly, fast and do great work. Lightning Lube is the epitome of a no BS business. There is no upselling or guilt tripping like you get at some auto shops. They just ask you what you're looking for and they'll let you know if you need anything else. Last time I was here, they told me I needed a new cabin air filter. I was like "eh, it' $40...". So they brought my current one in and showed it to me. "This is the air you're breathing currently", they said, shaking the dust from my filter. After that I told them to ring it up and install it.
I'm always in and out in 20-25 minutes, and always happy with the results. Prices are great and their check in offer on Yelp makes their oil changes even better. If you live near Scottsdale, this should be your go to place for oil changes and general auto maintenance.
