From all the analysis I've seen and received myself, I don't think this is really the case here.With direct injection and only a 5qt sump, I*m personally not going over 5k intervals. DI can be very hard on oil...and with the cheap synthetic 0w20*s out there with d1g2 approval, why risk it?
Why don't you use Flexible oil change interval which is up to 7,500 miles or 12 months? Mazda designed an oil life monitor for us to use, why don't we use it? I personally change my oil at about 30% oil life left which is about 5,000 ~ 5,500 miles between oil changes, although your gen-2 CX-5 is displaying mileage left.Just curious how many miles you all currently go on full synthetic oil between oil changes? I have been going 7,500 so far and havent had any issues, but Im wondering if I should switch that to 5k to be on the safe side.
