Thanks Bill, all good stuff!
I also drain and fill the transfer case and rear differential when I change the trans fluid and filter every 30,000 miles. This video missed these important items.
I just checked my transfer case and rear diff fluid levels. At 17,000 miles BOTH were about 30% below full. These items are worth checking to be sure Mazda filled them correctly.....
I've become a fuel additive junkie after reviving my Cummins Diesel injectors with a fuel additive. It may not be necessary but I'm adding injector cleaner to my fuel at every oil change, 5K miles. I have a controversial additive I put in the fuel every fill up, to absorb water and improve combustion. In the diesel world most of us have our favorite "snake oil" additive. I've logged a difference in FE when using fuel additives. They more than pay for themselves.
Down the road, at 30K, I'll add 1/2 quart of HSS Stiction Eliminator. This stuff turned our 100k mile 08 Honda Accord around. It drove better than new. It got it's best fuel mileage after adding. This is another diesel thing folks do every 30,000 miles or so to clean the soot out of the piston rings. At 250,000 miles on the Cummins HSS Stiction Eliminator eliminated blow by and quieted the engine.
No anti-seize on my plugs either. I'm very careful how much I tighten. And never, never use an impact gun on any aluminum part. I use old school speed wrenches replacing plugs and anything else it will reach. After a dozen or so stripped aluminum threads over the years I changed my methods. So far, no more trouble...
Avoid idling whenever possible...
