First time I’ve seen a dealer turn down money.
Is it okay to switch my CX-50 to full synthetic 5w30?
5w30 is what’s in it now, it is just Mazda oil (whoever makes it). I think it may be a blend, but no one has comfirmed.
MazdaUSA on Twitter hasn’t replied to me in a year, so I will try here.
Mazda branded oil is full synthetic.
They told me the original oil is a blend. It came out of a Mazda branded bottle. I don’t know who makes the oil for them. Synthetic oil changes are $20 more and they were adamant I should use the lower priced Mazda blend, since that is what it came from the factory with.
Mazdas oil is 0w-20 here in Canada, it’s full Synthetic of course, they don’t even offer a blend or non synthetic for their ‘newer’ vehicles. Like others have mentioned, you can use full Synthetic at any point, I jave no idea why that goomba is saying not to. It’s also your money. Costco has full Synthetic oil changes for 65$ in Canada. That’s what I used to get before I went Ev.
100% this.
I’v had my civic for 8 years and I’v done 2 oil changes every year for the whole ownership. About 90% of the oil changes were made at costco (always synthetic). Never had ANYTHING happen to my engine; never had to do any repairs. Hope this can reassure OP.
