GROUNDWORK — Build an oil-level trend for service Task: mazda-oil-consumption-log | Content version 2.0.0 Source page: https://csl-12-auto-repair.pages.dev/tasks/mazda-oil-consumption-log/ MODEL / APPLICABILITY [{"modelId":"mazda3-2017-us","market":"US","year":2017,"engine":"SKYACTIV-G 2.0 / 2.5 gasoline","configurations":["all","4-door","5-door","type-b-audio"]}] EXCLUSIONS Other model years and markets; imported Axela or diesel models; modified or aftermarket components with a different procedure. PREPARE [ ] Park in a safe place away from traffic. Work with the vehicle stationary, parking brake set and ignition off unless a step explicitly calls for a parked functional check. [ ] Can the manual’s measurement conditions be met without a warning or unsafe engine operation? [ ] Keep children and pets away from tools, fluids and coin cells. Never enter underneath the vehicle. [ ] Lint-free cloth [ ] Prior readings and odometer notes [ ] No oil required to create the comparison OBSERVE & RECORD Observation date: __________ Vehicle / equipment confirmed: __________ Keep odometer, level conditions and additions together; a dipstick position is not a measured consumption volume. Current odometer (miles): __________ Dated comparable MIN/MAX readings: __________ Known oil additions and product; unknown amount stays unknown: __________ Warnings, accessible leakage or other symptom: __________ Before care: __________ STEPS 1. [ ] Record the odometer and any oil added since the previous reading. Keep the amount unknown when it was not measured; do not estimate from a dipstick photograph. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=440 | PDF page 440 2. [ ] On a level surface, use a normally warmed engine, then switch it off and wait at least five minutes. Do not warm the engine for this task when a warning or unsafe condition exists. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=440 | PDF page 440 3. [ ] Wipe the dipstick, reinsert fully and read the MIN/MAX range. Check its O-ring is positioned correctly before fully reinserting it. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=440 | PDF page 440 4. [ ] Compare only readings with recorded, comparable conditions. A top-up between observations changes the comparison; preserve that addition in the log. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=440 | PDF page 440 5. [ ] Save the level, odometer, oil additions and product if known for service. This manual section supplies no consumption-rate pass threshold, so unexplained repeated loss stays an inspection question. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=438 | PDF page 438 6. [ ] Keep odometer, level conditions and additions together; a dipstick position is not a measured consumption volume. https://www.mazdausa.com/siteassets/global-resources/vehicle-resources/owner-manuals/2017/mazda3/2017-mazda3-owners-manual.pdf#page=438 | PDF page 438 DECISION CHECKS Can the manual’s measurement conditions be met without a warning or unsafe engine operation? Yes — ready for this check → Continue with the steps, stopping if the real component differs from the manual. Not yet / not sure → Preparation saved. Return when the condition is confirmed; leave the vehicle untouched. Oil warning, visible leak, or below-MIN/above-MAX level → Repeated unexplained decrease, warning or abnormal level: provide the log for inspection. Is there a usable level-and-addition history? Comparable readings and known additions documented; no unexplained decrease observed → Are all additions accounted for, with no unexplained repeated decrease or warning? Repeated unexplained decrease, warning or abnormal level: provide the log for inspection. → Repeated unexplained decrease, warning or abnormal level: provide the log for inspection. I have only prepared the plan → Plan prepared; no physical maintenance result recorded. Are all additions accounted for, with no unexplained repeated decrease or warning? Comparable history saved; no unexplained decrease observed → Comparable readings and known additions documented; no unexplained decrease observed The observation or repeat check is still incomplete → Plan prepared; no physical maintenance result recorded. Repeated unexplained decrease or warning needs service → Repeated unexplained decrease, warning or abnormal level: provide the log for inspection. RECHECK Does a later comparable reading show unexplained loss after accounting for documented additions? After care: __________ Retest: not checked / improved / unchanged / worse If an earlier condition changes, reassess the later checks and result. RESULT CHECK Is there a usable level-and-addition history? Comparable readings and known additions documented; no unexplained decrease observed Record only the result you actually observed. A saved web checklist is not confirmation that a vehicle has been repaired. Are all additions accounted for, with no unexplained repeated decrease or warning? Does a later comparable reading show unexplained loss after accounting for documented additions? STOP CONDITIONS Oil warning, visible leak, or below-MIN/above-MAX level Repeated unexplained decrease, warning or abnormal level: provide the log for inspection. A part, label, connector or fastener differs from the cited manual; access requires raising the vehicle; you cannot identify the correct component. SERVICE HANDOFF Take the recorded observations, their dates and any actual work history to the service provider. Repeated unexplained decrease, warning or abnormal level: provide the log for inspection.
