2008 Fit 100,000 Mile Necessary Service
 

I have a '08 Honda Fit. Reaching towards 100,000 miles. I've noticed getting 300 miles to the tank and now down to less than 270 after moving from NY to FL.

I've changed tires twice, battery twice, alternator blew out, oil changes, air filters, freon recently (although that hasn't fixed things after moving from NY to FL last year) and that's it.

Someone told me to change to spark plugs. Maybe wait on transmission fluid change.

What are the milestone recommended things I should do?

Valve adjustment.

Look at the owner's manual.

The fluids have a lifespan so there are consequences for not changing. Brake fluid is hydroscopic so old fluid can boil and rot brake system from inside out. Coolant anti corrosion and temp protection fails. Transmission oil becomes contaminated and breaks down. For example.

There are plenty of spark plug threads to research here. Easy change.

I second this. :)
