Just bought a new 2016 Mazda3 GS Sport for my wife. Glad to see a Canada-themed forum with so many knowledgeable members.
With my wife driving only 9,000 km per year it's annoying that Mazda insists on fresh synthetic oil and filter every 4 months. Fifty bucks' worth of Castrol French Perfume and oil filter every 3000 km... yeesh. I've seen helicopters that require less maintenance than this
Anyway as a DIYer I look forward to reading your tips and eventually contributing a few of my own.
