Prices may varyThe manufacturer's Safety Data Sheet classifies this product with one or more GHS Category 1 health hazards — the most severe tier. The hazard statements in quotes below are the verbatim GHS language from the SDS, as required by OSHA's Hazard Communication Standard. The line under each statement translates the GHS classification into plain language.
GHS Category 1 aspiration toxicity — thin, oily liquids can slip into the lungs if swallowed, causing chemical pneumonia.
If swallowed, inhaled, or splashed in eyes:
Call Poison Control immediately at 1-800-222-1222 (US, 24/7, free) and have the product container with you. Poison Control's standing guidance is to not induce vomiting after chemical exposure; they will direct first-aid steps based on the specific product.

TL;DR Active ingredient is not disclosed in any US-jurisdiction SDS or brand document · the community attributes the chemistry to PEA, but with no confirmation, the cleaning claim has no independent basis. Health score 4.3: DANGER from H351 carcinogen, H304 aspiration, and H336 narcotic effects, with a Prop 65 warning for a trace solvent component and a high-VOC naphtha carrier. Do not induce vomiting if ingested.
The active detergent in Jectron is not disclosed on the label, SDS, or any US Liqui Moly technical document · BITOG community discussion attributes the chemistry to PEA based on cross-regional parts-counter sources, but the brand does not confirm it in North America. Without that confirmation, the cleaning claim cannot be evaluated against a known chemistry class. Community evidence is positive: broadly trusted by a large, well-rated owner base and corroborated by multiple BITOG threads with 3,000-mile follow-up reports. The brand's protocol is one 300 mL bottle per 25·75 L (7·20 gal) tank, repeated every 1,200 miles. Liqui Moly markets DIJectron as a separate product for direct-injection intake-valve carbon.
Best fit for port-injection gasoline owners running non-Top-Tier fuel who want a brand-trust pick with a long European enthusiast track record. Skip it if you always run Top Tier certified gasoline (the OEM detergent package already covers maintenance dosing). Skip it for direct-injection engines with intake-valve carbon symptoms · Liqui Moly itself positions DIJectron, not Jectron, for that case. Skip it for severe rough idle or stalling; professional ultrasonic cleaning is the right call there.
SDS §2 is DANGER · H351 (suspected carcinogen Cat 2, naphthalene driver), H304 (aspiration hazard), H336 (narcotic vapour effects), H226 (flammable liquid), and H412 (chronic aquatic toxicity). The product listing carries a Prop 65 warning for a trace solvent component named in SDS §3. Lungs tier is recommended (Beyond SDS) based on the named aromatic carrier and H336. Do not induce vomiting if ingested · seek medical attention. The product combusts in the engine; exhaust byproducts are the environmental endpoint.
