Reduce, Reuse, Recycle: Daihatsu Mira Cocoa High-Mileage Vehicle with 148,809km - Part 1: What We Can Do for the Future, Things We Take for Granted

〜I hope you find this helpful,

a style of protecting the global environment while having fun

I am writing this with the hope of sharing this. I want to be as specific as possible so that you can use it as a reference.

　The Daihatsu Mira Cocoa I traded for with my child's Honda CR-Z. Thanks to careful maintenance, it is now

running so smoothly that it can easily climb steep hills at 2000 RPM with the air conditioning on, even with two adults on board.

The fuel economy is also

around 20km/L even for short trips within the peninsula,

which is better fuel economy than my 750cc motorcycle.

　I applied thick heat-resistant soundproofing material to the engine room including the hood, between the engine room and the cabin, and on the floor, and chose Yokohama dB tires for quietness.
[[phN_open]]I also replaced the dynamo and the battery, and I keep it topped up with a state-of-the-art charger.[[phN_close]]

Because of this, the power generation during driving can be suppressed, reducing the load on the engine, which in turn lowers engine RPM and contributes to fuel efficiency and quietness.

A quiet cabin

Well, it would be harsh to compare it to the Lincoln Towncar I brought back from America, but it ensures a level of quietness comparable to a standard modern Japanese sedan.

[[phN_open]]The undercarriage has been coated with chassis black by the dealer to ensure rust prevention. So...[[phN_close]]

this Mira Cocoa is one of my favorite cars.

　By the way, the maintenance staff at a certain Toyota dealership in Yokohama that I frequent felt that my maintenance requests were stylish, and they have been happy to accept even slightly unreasonable requests (such as applying KURE Rubber Protectant to the rubber parts of the undercarriage when it is jacked up, etc.).

　I am taking advantage of their kindness in a cute way...

　So, once something has been made, putting a burden on the environment, it is best to maintain it thoroughly and keep using it for as long as possible, provided safety can be guaranteed, as it is the kindest thing for the Earth. That is the point I want to recommend.

　This time, in particular, is about the details of the 1-year inspection.

…………………………………………………………………………………………………………

　Even though I have been driving it carefully, 10 years and 100,000 km is a rough guideline. Once you exceed that, it is considered a high-mileage vehicle. It was already a high-mileage vehicle when I replaced it. Since then, I have been taking it on long trips that require a bit of effort for a light car from the peninsula where I live, such as to the Chugoku region (about 500 km round trip) and Northern Kanto (about 1,800 km round trip), and the mileage is definitely continuing to increase.

I change the engine oil, oil filter, and CVT oil at every inspection, and I change the coolant and air conditioner gas early and often, using various additives to reduce friction. Therefore, because high RPMs are maintained stably, especially on highways,

the metal wears down slightly while in a state of low vibration, which leads to surface polishing with a high degree of smoothness in a good sense.

feeling. This is extremely effective. As the distance driven at high RPMs increases, I feel the friction decreasing even more.
Specifically, I am using an engine additive recommended by Toyota called MT10 to reduce friction in parts of the engine oil,

using Wako's MPS Mission Power Shield, a transmission oil leak prevention agent G133 | additive, to reduce friction in the CVT,

and using Microlon's air conditioning additive to reduce friction in the area where the air conditioning gas flows,

is what I am doing.

In particular, the change in the CVT was relatively dramatic.

Roughly speaking, I performed full maintenance immediately after exchanging it with my child, and I have been enjoying maintaining it ever since.

Please enjoy that part here.

These are the details of the overhaul. I have worked on quite a number of items.

These are more detailed improvements made after raising the basic condition through an overhaul. I have introduced the specific deadening state, various additives, maintenance chemicals, etc., and their effects.

It's getting long, so I'll stop here for now.
