Decent, but it's tough on the environment.

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.
About this product's hazards. This product's Safety Data Sheet uses signal word danger. Read the manufacturer's SDS and follow all safety instructions before use. CarCareTruth ratings translate the manufacturer's safety sheet. They do not replace the SDS or substitute for a hazard assessment specific to your task.
Health score is for adult use as intended, per the manufacturer's SDS. It does not model child ingestion, accidental spill cleanup, or off-label use. See the safety panel below for full hazard classification, and /disclaimer for the full editorial scope.

TL;DR DANGER-rated aerosol · use in ventilated areas, wear nitrile gloves. The synthetic-base formula stays slick for months and leaves a dry non-tacky film that sheds grit · a step up from petroleum sprays that need weekly touch-ups. NSF H1 food-safe certified. Prop 65 warning (benzene + n-hexane).
Super Lube 31110 lubricates hinges, cables, tracks, and garage door hardware. NSF H1 certified · cleared for incidental food contact. The synthetic base outlasts light petroleum sprays; community owners report months between reapplication. The dry-film additive leaves a non-tacky residue that sheds grit rather than collecting it · useful on cables and tracks where contamination causes faster wear. Overspray can deposit the dry film on adjacent painted surfaces.
Buy it for long-cycle mechanisms where weekly reapplication is a nuisance: garage doors, hard-to-reach hinges, cable-and-housing systems, food-processing equipment needing NSF H1. Skip it on rubber seals or o-rings without checking compatibility first. Regular enclosed-space users should prefer a pump-spray or drip format to reduce aerosol inhalation.
DANGER signal word (SDS §2). H304 (Aspiration Hazard Cat 1) at mixture level · do not induce vomiting if ingested; seek medical attention. H315 (skin irritation) at §2; nitrile gloves limit skin contact. No H335 at mixture level. Fine mist from aerosol application creates the primary inhalation exposure. The high-VOC carrier builds up in enclosed spaces · open a garage door before applying indoors. Prop 65 confirmed (SDS §15): benzene and n-hexane. N-hexane in §15 is likely a trace impurity in the n-heptane fraction · a standard petroleum SDS practice. The dry-film additive (PTFE) is not classified as PFAS under current regulatory definitions. Environment score 4.0: high-VOC aerosol, non-biodegradable petroleum carrier.
The core difference is staying power. WD-40 original is well-documented by community as a short-duration lubricant · the light petroleum-spirit carrier evaporates, leaving mechanisms dry again within days to weeks. Super Lube 31110 uses a synthetic base with a dry-film additive that remains on the mechanism after the carrier evaporates, providing lubrication community owners confirm lasts months. The tradeoff: both products carry a Prop 65 warning and the Super Lube has a DANGER signal word (vs. WD-40's WARNING), so ventilation is more important with Super Lube 31110 in enclosed spaces.
The petroleum-distillate carrier (hydrotreated light distillates, naphtha) is a potential concern for certain rubber compounds. The NSF H1 food-grade certification confirms the formula is cleared for incidental food contact in food-processing environments, but this does not guarantee compatibility with all rubber seal or plastic types. SDS Section 10 reports no specific reactivity data for the mixture. Check manufacturer compatibility documentation before applying to EPDM, Buna-N, or polycarbonate components.
Super Lube 31110 contains a dry-film additive (Syncolon) that leaves a non-tacky residue after application. This additive is polytetrafluoroethylene (PTFE) in macroparticle form · confirmed present per the product name and NSF registration, though below the 1% SDS §3 disclosure threshold. Macroparticle PTFE is not classified as PFAS under current EPA TSCA definitions or OECD 2021 criteria; short-chain fluorinated compounds (C4·C8 PFAS) are the regulated class. The contains_pfas field is false based on this distinction.
NSF H1 certification (registration #125601) means the lubricant is approved for incidental food contact in food-processing, beverage, and pharmaceutical manufacturing environments. This does not mean the product is edible or ingestion-safe · the SDS carries a DANGER rating and explicit 'Do Not Induce Vomiting' instruction. In practical home-use terms, the H1 certification confirms a high formulation standard and is a meaningful differentiator for any application where lubricant might occasionally contact surfaces that touch food.
The aerosol format creates a fine mist near face and hand level. While SDS §8 states respiratory protection is 'not required under normal conditions,' the DANGER signal word and high-VOC aerosol chemistry warrant ventilation in enclosed spaces. Open a garage door or window before applying. Outdoors or in well-ventilated areas, normal handling precautions are adequate (no H335 at mixture level).
