Everyday Car Mechanics
Demystify what happens under your car's hood with practical, hands-on knowledge. Learn how to check vital fluids, diagnose weird noises, understand core engine systems, and deal honestly with mechanics.
Like Duolingo, but for Everyday Car Mechanics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
27 levels across 4 sections, about 54 minutes end to end, roughly 11 days at five minutes a day. It moves through Under the Hood: Vital Signs and Fast Fixes; Diagnosing Problems: Lights, Sounds, and Smells; How the Machine Works: Core Systems; and Ownership and Upkeep: Keeping It on the Road. It starts from scratch.

Key ideas in Everyday Car Mechanics
- Translucent plastic reservoirs feature MIN and MAX lines visible directly through the container
- Oil splashes around the tube while driving, creating a false reading on first pull
- Wiping the dipstick clean allows a fresh, crisp oil line to register on the hatch marks
- A clean wipe onto a white rag reveals whether the oil is amber and healthy or sludgy and blackened
- Opening a hot coolant reservoir can spray scalding pressurized steam
- Brake fluid absorbs moisture from outside air, which degrades braking performance over time
- The correct target tire pressure is printed on the sticker inside the driver's door jamb, not on the tire sidewall
- Tire pressure must be checked 'cold' before the friction of driving heats up the air inside the rubber
- Tire pressure drops roughly 1 PSI for every 10-degree drop in outside air temperature
- If all of Lincoln's head is visible, the tread depth is less than 2/32 of an inch and the tire is legally worn out
- Shallow tread cannot channel standing water away from the contact patch, causing hydroplaning and dangerously long wet stopping distances
- Tires should be measured across the deepest central grooves where water evacuation occurs
- Windshield washer fluid is simple detergent and water/alcohol that cleans glass without interacting with sealed mechanical systems
- Coolants, brake fluids, and power steering fluids require strict chemical compatibility to avoid dissolving internal rubber seals or coagulating
- The washer fluid reservoir cap is marked with a windshield wiper and water spray icon
- The battery's main job is delivering a huge burst of power to start the engine
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Everyday Car Mechanics the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
A real question from this course. Take your best guess.
Why shouldn't you trust the oil line the very first time you pull the dipstick out?
