- [Kia Optima 2011–2015](https://carcasefile.com/vehicles/kia-optima-2011-2015/): Reliability 4/10. The TF Optima was the car that made people take Kia seriously : sharp Peter Schreyer styling, a long warranty, and a lot of equipment for the money. The catch is the 2.4L Theta II

- [Volkswagen Jetta 2005–2010](https://carcasefile.com/vehicles/volkswagen-jetta-2005-2010/): Reliability 5/10. The Mk5 Jetta is really three different cars: the 2.5L five-cylinder (solid, boring, underrated), the 2.0T FSI GLI (fun, but the cam follower can eat the camshaft), and the 2009–20
- [Volkswagen Jetta 2011–2018](https://carcasefile.com/vehicles/volkswagen-jetta-2011-2018/): Reliability 5/10. The Mk6 Jetta is roomy, fun to drive, and cheap to buy used, but it asks more of you than a Corolla. The turbo gas engines (2.0 TSI, later 1.8 TSI) can stretch their timing chains

## Viral claim fact-checks (worst verdicts first)

- [Is the "$2 liquid that destroys engine sludge forever" real? Our shop-floor verdict.](https://carcasefile.com/claims/2-dollar-engine-sludge-destroyer-liquid/): Verdict Dangerous. An aggressive solvent flush on a high-mileage engine is a textbook way to spin a bearing. The viral 'kitchen-cabinet flush' is folklore that real shops spend money cleaning up after.
- [Is the "$1 Japanese oil trick" that stops engine wear forever real?](https://carcasefile.com/claims/1-dollar-japanese-oil-trick-mos2-engine-wear/): Verdict Misleading. The 'Japanese oil trick' is almost certainly MoS2 (molybdenum disulfide), a real industrial friction modifier. It is German, not Japanese (Liqui Moly popularized it), sold openly at every parts store for $15-20, has real but modest measured friction benefits, and was never buried by anyone.
- [Does a "$1 mineral" really double car battery life? The Epsom-salt reality.](https://carcasefile.com/claims/1-dollar-mineral-doubles-battery-life-myth/): Verdict Outdated. The mineral is Epsom salt (magnesium sulfate). It was a real desulfation hack for serviceable flooded-cell batteries 40+ years ago. It does not work on modern sealed AGM or EFB batteries, and trying it on yours will void the warranty without helping the battery.
- [Is the "$2 liquid that stops any leak" really banned in 11 states?](https://carcasefile.com/claims/2-dollar-stop-leak-banned-11-states/): Verdict Misleading. Automotive stop-leak products are not banned in any US state. The products are real (Bar's Leaks, BlueDevil), they work in specific narrow situations, and they can permanently damage your cooling or oiling system if applied to the wrong leak.
- [Does a "$3 liquid" really kill car rust permanently? The phosphoric-acid reality.](https://carcasefile.com/claims/3-dollar-rust-killer-permanent/): Verdict Mostly False. The $3 liquid is almost certainly phosphoric acid (sold as Ospho or Naval Jelly). It converts surface rust to iron phosphate. It does not kill rust 'permanently,' does not restore perforated steel, and was never buried by anyone. It has been on hardware store shelves continuously since the 1940s.
- [Do shops lose money on cheap oil changes? We opened a real shop's books to find out.](https://carcasefile.com/claims/59-dollar-oil-change-loss-leader/): Verdict Mostly False. A quick lube's true all-in cost is roughly $16–40 per car. Even a $59 special turns a gross profit before the upsells start. The 'below cost' story is only true at full-service shops doing far more work per visit, which is a different product wearing the same name.
