[Wiotte]

Now I have a 2017 Mazda, requires 0W-20. Has burned a quarter qt. in 5K miles. Will switch to 5W-30 for its first oil change. Guaranteed I’ll burn zero oil between changes.
This whole 0W-20 nonsense is meant to increase the fleet mpg, but it will decrease the life of the engine. But since most of us won’t drive 400,000 miles on one engine, it’s moot. I just hate watching the oil level decrease substantially between oil changes. It’s goes against my grain to open a qt. of synthetic just to top off the level.
