CarSpecFix

CarSpecFix is a free reference site for car owners who need reliable maintenance numbers fast. Instead of digging through forums or guessing, you pick a year, make, and model and get the specs that matter for everyday upkeep: engine oil capacity and recommended viscosity, factory tire sizes, cold tire pressure, and NHTSA recall records for that vehicle.
What sets CarSpecFix apart is sourcing. Every figure on the site cites where it came from, usually the owner's manual page or the official data source, so you can check the number yourself before you pour oil or inflate a tire. Pages are published only after their figures have been source-checked, which means the site prefers leaving a gap over printing a guess. For anyone doing their own oil change, buying tires, or confirming whether a used car has open recalls, that traceability saves time and avoids costly mistakes.
Beyond raw specs, CarSpecFix explains common OBD-II trouble codes such as P0300 (random or multiple cylinder misfire) and P0455 (large evaporative emission leak) in plain language: what the code usually means, likely causes, and what to check first. It also covers frequent symptoms like squeaking brakes and lists warning signs that mean you should stop driving and get the car inspected rather than wait.
Coverage focuses on popular models from Toyota, Honda, Ford, and Tesla, and keeps growing as more vehicles are verified. The site is free to use, needs no account, and works on phones, so you can look up a spec in the garage or at the parts counter.
Who it is for: DIY mechanics, new car owners, used car shoppers, and anyone who wants a quick, sourced answer to "how much oil does my car take" or "what tire pressure should I run" without wading through conflicting advice. CarSpecFix aims to be the simple, trustworthy place to look up car specs by year, make, and model.
