Mechanics in Project Zomboid (Build 42)

Crafting5 skill books1 recipes

Mechanics is a Crafting skill. Taking it from 0 to 10 costs 32,775 XP before multipliers — 5 skill books multiply what you earn on the way; the Mechanic occupation starts with 4 levels, and it unlocks 1 recipes.

From the Build 42 dedicated server's files (depot manifest of 23 Sept 2026).

XP for each level

Level 10 alone costs 9,000 XP — 27% of the total.

How to level Mechanics

Mechanics XP comes from repairing parts in a vehicle's mechanics menu — and a failed repair still gives XP.

What you actually earn is scaled first. Starting with no levels in Mechanics cuts every gain to ×0.25; a starting +1 is ×1, +2 ×1.33 and +3 or more ×1.66. Fast Learner adds ×1.3, Slow Learner ×0.7. How the multipliers work.

Mechanics skill books

Reading a volume multiplies the Mechanics XP you earn while your level is inside its range: every tenth of the book read adds a tenth of the multiplier. The game lets you open a volume from one level below its range, and not once you are past it (ISReadABook.lua).

Start with Mechanics

Levels a new character gets in Mechanics — and, through them, a faster XP rate (see above):

  • Mechanicoccupation · +4
  • Vehicle Knowledgetrait · +1

Mechanics from TV and VHS

6 VHS tapes give 1,050 XP. Both stop counting once the skill reaches level 3 in the default sandbox settings, and before the multipliers above. Shows and tapes, by name.

Recipes you learn by levelling Mechanics

Reaching the level teaches the recipe — no magazine needed.
