Dealer won't use synthetic oil - 2022 CX-5 Turbo

[sm1ke]

Maintaining your Mazda with the best synthetic oil is essential for ensuring optimal performance, fuel efficiency, and engine longevity. By choosing high-quality synthetic oil brands like Mobil 1 Extended Performance, Castrol EDGE Full Synthetic, or Royal Purple High-Performance Synthetic, you can provide your Mazda with the protection it needs to run smoothly and efficiently.

Ready to give your Mazda the care it deserves? Start by selecting the best synthetic oil for your vehicle and experience the difference it can make. And if you need further assistance, don't hesitate to book a consultation with a mechanic at Mazda of New Bern!

Most car dealerships are privately owned entities, not owned by the car manufacturers themselves. That means that they (dealerships) can do whatever they want, as long as it doesn't breach whatever agreement they have with the manufacturer, and as long as it doesn't hurt or misrepresent the brand. So, the dealership can recommend a better oil, in order to offer a "premium" oil change that they can charge a bit more for. However, Mazda, as a brand, still does not require full synthetic oil for the 2.5T engine, and Mazda as a brand, has not released any TSBs or special service campaigns to advise owners to use full synthetic.

IMO, everyone should be using full synthetic if it's available to them. The cost difference between conventional and full synthetic is negligible, but the benefits are clear. Regardless of Mazda choosing not to recommend full synthetic for the 2.5T, I'll still use it for every oil change.

You are correct. I emailed my contact in Irvine Ca Mazda America. Mazda does not take a position on synthetic or non synthetic. They only specify SAE and API certified oil. I also use only full synthetic.
