KAISAL Engine Oil Tester — Gasoline & Diesel Analyzer with 50in Flexible Probe, 2.8in Backlit Display

Keep an eye on your engine oil without guessing: this compact diagnostic tool measures oil transmittance and temperature to indicate when oil is still serviceable or needs replacement. Designed for both gasoline and diesel lubricants, the KAISAL tester combines a clear 2.8-inch backlit display, audible prompts, and a long PTFE probe so you can test oil directly through the dipstick tube or from a removed sample.

How quickly and accurately will this tester tell me oil condition?

The tester produces a transmittance reading in about 2 seconds using an integrated photoelectric and temperature sensor, delivering fast results you can rely on. Readings are shown on the LCD with an analog-style bar and clear symbols to indicate oil health.

• 2-second transmittance measurement for rapid checks
• High-precision photoelectric sensor for consistent readings
• Temperature compensation to improve accuracy

Can I use it on both gasoline and diesel engines?

Yes — the KAISAL tester supports a wide range of lubricant standards and offers separate sampling modes for gasoline and diesel oils to reflect their different baselines. This helps give a clearer indication of when each oil type is degrading or contaminated.

• Dedicated gasoline and diesel measurement modes
• Works with most commercial engine oils and lubricants
• Indicator thresholds tailored for each engine type

What do the screen symbols and sounds mean?

The display and audible alerts simplify interpretation: an "OK" mark appears when transmittance is healthy, a caution symbol shows when attention is needed, and a cross warns when oil is poor. Each result is paired with a beep to ensure you notice the status even in noisy garages.

• "OK" for 60–100% transmittance — normal use
• "!" for 30–60% transmittance — inspect soon
• "×" for below 30% transmittance — change oil advised

How do I test oil safely and get reliable readings?

For in-vehicle checks, run the engine briefly to circulate oil and ensure probe immersion; for removed samples, shake the bottle to resuspend particulates. Observe temperature guidance and clean the probe before every test to avoid contamination or false readings.

• Run engine one minute before testing in-situ for accurate circulation
• Shake stored oil samples to prevent particle settlement
• Ensure oil temperature is below 60°C and wipe probe clean first

Who is this for? The KAISAL Engine Oil Tester is aimed at DIY mechanics, fleet managers, workshop technicians, and car owners who want a quick, low-cost way to monitor oil health between service intervals. It’s especially useful when you need fast on-site diagnostics, want to avoid unnecessary oil changes, or need to spot contamination early. Lightweight and battery-powered with an anti-slip grip, the unit is portable for roadside checks or professional use, and KAISAL backs it with a three-year service promise for added confidence.
