Key Features
Optical Engine Oil Reading with Gasoline and Diesel Modes
High-Precision Optical Probe
The integrated photoelectric transceiver sensor detects engine oil transmittance to help evaluate oil contamination and impurity level.
800mm Flexible PTFE Hose
The 800mm hose probe makes sampling easier around the engine bay. PTFE material resists oil, oxidation, and corrosion for longer service life.
Gasoline And Diesel Modes
Separate gasoline and diesel engine oil modes help users check different lubricant oil standards more accurately.
Oil Temperature Measurement
The built-in temperature sensor displays the actual oil temperature and supports °C / °F switching for easier reading.
2.8-Inch Backlit LCD
The backlit 2.8-inch screen shows battery level, selected engine type, transmittance, oil temperature, and result symbols clearly.
Sound Alarm And Result Reminder
The tester uses screen icons and sound reminders to help users decide whether the oil is acceptable, needs attention, or should be replaced.
Silicone Handheld Grip
The silicone grip supports single-handed operation when checking engine oil.
Battery-Powered Tester
The 175 × 72 × 29mm tester operates on 6V from four 1.5V batteries.
Engine Oil Transmittance
AS503 measures engine oil transmittance in gasoline and diesel modes to support oil condition checks.
Optical Probe Reading
The probe reads light transmission through engine oil and reflects contamination or suspended particles that affect transparency.

การใช้งานที่ปลอดภัย
Treat the Score as a Screening Result
Engine Oil Only
AS503 is intended for gasoline and diesel engine lubricating oil. It is not a brake fluid, transmission fluid, or power steering fluid tester.
Optical Detection Limit
Because AS503 uses an optical detection probe, it is not suitable for engine oils containing molybdenum disulfide (MoS₂), organic molybdenum, graphene, or similar additives.
Suzuki J20A Not Supported
AS503 does not support the Suzuki J20A engine. Contact AUTOOL Store before ordering if this engine is your intended application.
Check Oil Additives
Do not use AS503 with oils containing molybdenum disulfide, organic molybdenum or graphene additives.
ช่วงเวลาตรวจสอบที่แนะนำ
Use AS503 as a reference check every 5,000-10,000 km, depending on engine condition, oil type, driving environment, and maintenance schedule.
Interpret Engine Oil Transmittance in Context
Select only a listed fluid and use a clean, representative sample. The condition score is the tester’s screening output, not a direct measurement of viscosity, wear metal, contamination species or remaining service life.

คำถามจากผู้ซื้อ
Fluid Fit, Method and Result Questions
อะไร AUTOOL AS503 Test?
AS503 tests gasoline and diesel engine lubricating oil by checking oil transmittance with an optical probe. It also displays the current oil temperature to help users evaluate engine oil condition during maintenance.
Can AS503 Test Both Gasoline And Diesel Engine Oil?
Yes. AS503 supports separate gasoline engine and diesel engine oil mode selection. Select the correct engine type before starting the test.
How Should I Read The Transmittance Result?
- When transmittance is between 100% and 50%, oil replacement is generally not required.
- When it is between 50% and 30%, the screen shows a warning symbol.
- When it drops below 30%, the tester beeps and suggests immediate oil replacement.
- Use the result together with actual vehicle service requirements.
Which Engine Oils Are Not Suitable For AS503?
AS503 relies on optical detection, so it is not suitable for engine oils containing molybdenum disulfide (MoS₂), organic molybdenum, graphene, or similar substances. These additives may affect optical analysis results.
Does AS503 Support Suzuki J20A Engine Testing?
No. AS503 does not support the Suzuki J20A engine. Contact AUTOOL Store for compatibility help with another model or engine.
How Often Should I Test Engine Oil?
A practical reference is to check engine oil every 5,000-10,000 km, depending on oil type, driving conditions, vehicle age, engine condition, and the maintenance schedule recommended for the vehicle.
What Batteries Does AS503 Use?
AS503 uses 6V power from 4 × 1.5V batteries. Battery inclusion should follow the final package listing, so do not assume batteries are included unless confirmed.
What Should I Do If The Hose Or Probe Gets Stuck?
Do not force the hose or probe out if it becomes jammed. Stop operation, check the surrounding position carefully, and contact support if you are unsure how to remove it safely.
What Is Included In The Box?
Package contents: AS503 main unit with integrated flexible probe, user manual, and retail box. AS503 requires 4 × 1.5 V batteries; battery inclusion follows the selected package listing.
What Is The Difference Between AS503 And Other AUTOOL Fluid Testers?
- AS503 is for gasoline and diesel engine oil transmittance testing.
- AS501 and AS502 are brake fluid water content testers.
- AS505 is for transmission fluid transmittance.
- AS506 is a brake fluid boiling point tester.
- AS507 is for power steering fluid transmittance.
