My cX5 also says only 0w-20 as well as my Toyota Land Cruiser 2017.

Yes, the dealer where I purchased the car in February (South Tacoma Mazda).Was it done at a Mazda dealer ?
I think I would question why they didn’t use the Recommended oil.Yes, the dealer where I purchased the car in February (South Tacoma Mazda).
Yeah, I will give them a call tomorrow and ask.I think I would question why they didn’t use the Recommended oil.
While 0W-20 oil is recommended to your 2.5L non-turbo in the US, and you can question your Mazda dealer about why the usage of 5W-20 oil, but the viscosity is fine to your 2.5L. See the oil viscosity chart used worldwide by Mazda for 2.5L posted in post #61 above.I had my first oil change today, didn't ask for any specific oil when I left the car. The invoice says they used 5W20. Gas, non turbo.
Yeah, I saw that chart. Still want to know why they chose to use 5W20 instead of 0W20. Did they not have any 0W20 available? Did they use 5W20 because it's summer?While 0W-20 oil is recommended to your 2.5L non-turbo in the US, and you can question your Mazda dealer about why the usage of 5W-20 oil, but the viscosity is fine to your 2.5L.

While your saying about conventional oil can be true, but based on recent history and class-action lawsuit of oil sludge issue on VW / Audi 1.8T turbo caused by cooked conventional 5W-30 oil from oil feed line to the turbo charger, I’d never use not-much-cheaper conventional oil on any turbo engines.There is nothing wrong with using the 5w30 dino oil in your turbo. Changed at the manufactures recommded intervals the engine will probably lasy 200,000+ miles. While I would use a Synthetic, it is not necessary with modern oils that meets specs. Somethimes we overthink and rant about what we don't understand. However; since you asked for synthetic and didn''t get it, the dealer lied about it and should be reported to the distrik manager. Ed
The only reason your Mazda dealer used 5W-20 oil is it’s cheaper when they purchased the 5W-20 oil in bulk. Also there’re more conventional or blend oils in 5W-20 viscosity than 0W-20. Finding out if the 5W-20 oil your dealer used to your 2.5L is full synthetic、blend、or conventional, and what brand, IMO, is more important. If it turns out to be not full-synthetic, may be you should consider to change the oil a bit earlier, say 5,000 miles instead of 7,500 miles, next time.Yeah, I saw that chart.

The little sticker showed a mileage based on 5000mi service interval which is what I had set up in the computer.Does the little sticker show the the honest requirement for your next oil change, the time and mileage from your owner's manual, or is it another lie with a shorter time? Follow the owner's manual.
This makes my blood boil, as I have had the exact same experience, twice, with different vehicles, different times.The incompetents I bought our car from offer the first oil change free. The Mrs. made the appointment, took the car in, waited the hour, was called to get the car, and drove it home. I asked to see the paperwork they gave her. No paperwork. What! I checked the dipstick. The oil was dirty and a half quart low. They never touched the car. I called back, happened to speak with the same service writer. He said that he remembered the car and told me that they had certainly changed the oil and filter. I asked him to check the service order and tell me what oil and filter were billed to that job. He got really quiet. Oops. They actually had forgotten to change the oil. (At least they didn't drain it and forget to refill it.) He said to bring it right back for a free oil change. Right......
I'm like that too, it's hard to get over being cheated.I still get riled up about this after 20 years.
Exactly.What I find annoying is not the dollar value but rather the lack of integrity that could compromise the durability and eventually the safety of the vehicle and ultimately the passengers.
