Hello All,
Hope everyone is well. I wanted to get some guidance regarding two of my vehicles OCIs.
1. Mazda CX-9 – Mazda recommends conventional – 6 months or 7,500. I am running synthetic 5w-20 and plan to do 1 year or 6,000. Sump is 5.5 qts. Don’t consider severe service...plenty of highway, etc.
2. Dodge Durango RT (5.9L) – Dodge recommends conventional – 6 months or 6,000. I am running synthetic 10w-30 and plan to do 1 year intervals (less than 2k a year in mileage). Sump is 5 qts. Don’t consider severe service...plenty of highway, etc.
My main worry is not the mileage but a year on synthetic (which goes against 6 month on conventional). Thanks again to everyone on this site.
