Ok your all bitchin about where to go and who's better and blah blah..it's JUST an oil change..whats so complex about taking a bolt out and letting the oil spill out...most of it has to do with a factory-approved oil filter...all places do the same job, no one is better..as long as the oil gets chaged and you have a good filter then who cares. As for the prices, lots of companies base their prices based on their company establishment..Mr Lube is nation wide popular and have a name for themselves so they have higher prices, they know people will go there and people do go there because they know they are a well established place to go.
As for the type of oil, i would only use big names such as Castrol or Quaker State because atleast they have done tests to support their oil, unlike petro canada brand junk, that's just oil made to be sold at the gas station for a quick "top up" until the next oil change...And remember, Mr Lube is warranty approved for new vehicles.
