KAISAL Engine Oil Tester Handheld Analyzer for Gasoline & Diesel, 50in PTFE Probe, 2.8in Backlit Display

KAISAL Engine Oil Tester is a handheld diagnostic tool that measures engine oil transmittance and temperature to quickly indicate whether gasoline or diesel oil needs attention.

Keep track of your vehicle's lubricant health without guesswork: this compact analyzer uses a photoelectric sensor and temperature probe to detect contaminant levels and provide clear OK/Warning/Change indications. Its long, 50-inch PTFE probe reaches deep dipstick openings, and the 2.8-inch backlit LCD shows transmittance and temperature at a glance. Designed for DIY mechanics, fleet managers, and technicians, it speeds routine checks and helps you decide when to service or swap engine oil.

How fast and reliable is the oil detection?

The KAISAL tester returns oil transmittance readings in about two seconds using a high-precision photoelectric sensor and built-in temperature compensation. Results are simplified into three outcomes—OK, attention, or change—each accompanied by an audible beep, making interpretation immediate even in noisy garages.

• 2-second measurement cycle for quick garage checks
• Analog-style bar graph plus OK/“!”/“×” display for instant interpretation
• Audible beep for each result to avoid missed alerts
• Temperature sensor to stabilize readings and avoid false positives

Can it test both gasoline and diesel oils accurately?

Yes — the tester supports a broad range of lubricant standards for gasoline and diesel engines. It separates sampling modes for each fuel type so you can compare transmittance against appropriate baselines and better assess whether oil has metal particles, soot, or other contaminants.

• Selectable sampling for gasoline or diesel oils
• Transmittance measurement detects particulates and degradation
• Useful for conventional, synthetic, and blended lubricants
• Works on used oil in containers or directly from the engine dipstick hole

What makes the probe and display suited for workshop use?

The unit includes a 1270 mm (50 in) flexible PTFE probe that resists oil, oxidation and corrosion so it reaches deep reservoirs without damage. The 2.8-inch high-definition backlit LCD presents transmittance and temperature clearly in daylight or low light while a non-slip, ergonomic housing enables steady one-handed operation.

• 50-inch PTFE hose probe bends to fit dipstick openings
• Durable materials resist oil and chemical exposure
• Large backlit 2.8-inch LCD for easy reading in any lighting
• Non-slip silicone grip and lightweight handheld design

How should I prepare and interpret test results safely?

For consistent readings, ensure engine temperature is under 60°C and the probe is immersed in oil. Shake collected samples before testing to redistribute settled particles; if testing in-vehicle, run the engine briefly to circulate oil. Treat the device as an aid — use the OK/attention/change indications to decide when to consult a mechanic or change oil.

• Verify engine temperature is below 60°C before testing
• Clean probe before each measurement and immerse fully in oil
• Shake bottled samples or run engine one minute before in-situ tests
• Automatic power-off after 5 minutes to save battery

Who is this for? The KAISAL Engine Oil Tester is ideal for car owners who perform their own maintenance, independent mechanics, and fleet operators who need fast, repeatable oil checks. It’s especially useful when you want a non-destructive, on‑the‑spot indicator of oil cleanliness and temperature without sending samples to a lab. Backed by a three-year product service commitment, this tool helps you monitor lubricant condition, avoid premature wear from degraded oil, and plan timely oil changes with confidence.
