Awesome tip! Google your local mechanic or repair shop and look at the reviews. These reviews are usually accurate if there are many entries and take your own oil to the mechanic. They will happily use it in your vehicle and just charge you labor. One issue is with taking your own synthetic to the dealership is that some may refuse. This is just so you can buy their own brand or whatever oil they use! This does not void your warranty! Also you will find a local mechanic in the process who will possible give you better service compared to a huge dealership. Don't forget an awesome filter by Amsoil or Wix!
