That is not true! Flexible OCI is up to 10,000 miles or 12 months whichever comes first. The "Oil change due" message most likely will be displayed a lot earlier than that and at the lastest at 10,000 miles mark if you had many long trips, long before 12,000 miles your service advisor suggested! Many people had done UOA and Mazda moly oil can easily last way more than 7,500 miles!
You can set your Maintenance Monitor on oil change to "Flexible", but change oil anytime before the reminder coming up. This's what I did, changing oil at 50K, and 56K, with Mazda moly oil at about 40% oil life left. I don't use any dealers for routine maintenance as I found most of them are not trustworthy, I use them only for warranty service.
Car dealer's service department is using bulk Castrol oil for more profit. I bet if you go to parts they'll have Mazda moly ready to sell to you. I'd keep using Mazda moly oil as it has good reputation and fair price. My dealer charges $10 more for oil change with moly, but you have to ask for it otherwise the generic "Preferred Choice" oil would be used
Thank you. I prefer 10 dollars more for 7500 or so miles. that is perfect win win for me. I will insist on Mazda Moly next time. Hopefully use this one for 6-7K miles.
Man it feels a little more fast after the oil change. mpg though is more or less same or slightly better.
Which dealer in DFW has mazda moly confirmed?
