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

The CX-5 turbo owner's manual has the correct capacity of 5.1 quarts.
more like 5.1 L . Mine takes 5.3 quarts to get it to max with new filter oem.
5quarts is only at the L mark on the stick.

on my non turbo 5quarts is little bit above the middle between L and H.

go figure why the manual says different.

5.1qts puts me right between the L and H. it then stays there for the remainder of the OCI.
 
You simply won't convince me I am hurting my engine by doing 7500 or even 10K oil changes per manufacturer.
I don't believe any of the BS conspiracy theory that car companies don't care what happens to your car after the warranty. That they don't care if cars don't last these days. They learned what happens if you build 'disposable' cars. People still won't buy "American cars" because of the crap they built in the 80s.
You also cannot convince me that motor oils and engine technology hasn't advanced significantly since 1950 when the 3,000 mile OCI was invented in the USA.
Why is that a USA thing?
 
Oils have improved considerably, however, in the modern era of positive crankcase ventilation and direct injection, that pushes in the other direction. I've seen enough engine tear downs to avoid 10k OCI. I think 5k is perfect, especially with the turbo, and would only push 7.5k if I were a highway commuter.

Ok, well, I guess there's no point in trying to convince you of anything is there. Your mind is made up.
For everyone else out there, engines have evolved a long way from the 1950's, and in some respects, not necessarily in a good way. These small displacement 4 cyl turbo engines, putting out over 200 HP, need fresh oil more often than you think. The tolerances are much tighter to begin with, so any kind of contaminants or sludge can destroy them. Then there's the turbo of course, which needs good clean oil. Lastly is the matter of the direct injection technology that's used now. It is a known problem that these engines all suffer from oil dilution to some degree. Some are worse than others (hello Honda 1.5L turbo). Coupled with the watered down oil viscosity (0W20, or worse), now in use, oil dilution is a real problem. I'll gladly stick with frequent oil changes versus running my cars out. I actually don't drive that much anymore (retired), so I do mine once a year. My DD does about 5,000 kms a year (3,500 miles), and my other car does about 3,000 kms a year. The cost doesn't bother me either. It's a small price to pay.
