Fuel efficiency was another key consideration. I wanted an engine that could provide a good balance between performance and fuel consumption. I read reviews and specifications to get an idea of how many miles per gallon I could expect from various engines.
Maintenance Requirements
I knew that regular maintenance would be necessary for keeping my engine in top shape. I looked into the maintenance requirements for different engines, including oil changes, air filter replacements, and spark plug checks. Choosing an engine with straightforward maintenance was important to me.
