Which oil should I be using for my vehicle, conventional or synthetic?

For a modest increase in initial cost, synthetic oil promotes better performance and greater longevity for most vehicles. It also allows for performs more reliably during extreme cold or heat, also allowing for a longer driving interval before it needs to be replaced. Though the majority of the vehicles in Ontario can make do with conventional oil, we recommend synthetic oil for our climate conditions, especially for those used on the job or for heavy duty work. Remember, you can always switch back to conventional oil after trying synthetic, or even alternate depending on the season.
