Some suggestions

I have been using your app for awhile and I was thinking that it would be nice if I could use just one app for all car maintenence. It would be great if I could put in like the odometer when I change the oil, whether I used conventional oil or synthetic and same with transmission fluid.

For example I use your app on two different cars, one I use conventional oil and the oil and filter need to be changed every three thousand miles. and the other uses synthetic with the filter changed every 3000 miles and the oil every 9000 miles. It would be nice if when I put in a fill up that is getting close to one of those intervals it lets me know.

I live in Canada, so most of the time I use liters for units. Occasionally, I travel to the U.S., and would like to enter the units as gallons. I have tried changing the units to gallons, and then changing back to liters when back in Canada, but 10 gallons then becomes 10 liters, and $2.899 per gallon becomes $2.899 per liter.

It would be nice if the app converted whatever units were used per fillup to the default units. So, a fillup that was entered as 10 gallons would become 38 liters. To do this, I assume you would have to enter the units per fillup.
