I’m looking to get an oil change and I’m noticing a wide range of prices at different shops. Some places are charging as low as $30, while others are asking for over $100. I recently came across a service called carzinity, which offers competitive pricing, but I’m still not sure if it’s worth it. 

I’m wondering, what’s the reason for this big price difference? Is it due to the type of oil used, the brand of the shop, or are there other factors involved? Any advice would be greatly appreciated! 

Thanks in advance!
