KAISAL Engine Oil Tester for Petrol & Diesel — 50in Flexible Probe, 2.8in Backlit Display, Fast 2s Readings

The KAISAL Engine Oil Tester is a handheld, high-precision analyzer that quickly measures engine oil transmittance and temperature for gasoline and diesel engines using a 50-inch flexible probe and 2.8-inch backlit display.

Maintaining clean, effective engine oil is one of the most cost-effective ways to protect vehicle components and prolong engine life. The KAISAL tester gives drivers and mechanics a fast, objective way to check oil condition without draining the sump: it measures light transmittance and temperature to flag contaminated or degraded oil, provides audible and visual alerts, and supports separate gasoline and diesel sampling for more accurate results.

How fast and reliable is this tester for routine oil checks?

The device delivers results in about two seconds using a photoelectric transmittance sensor and integrated temperature reading. Its fast response helps you decide whether oil needs replacement during routine maintenance stops.

• 2-second transmittance measurement
• High-precision photoelectric and temperature sensors
• Three-level result display (OK, attention, change) with beeps
• Backlit 2.8-inch LCD for clear readings day or night

Can I use it on gasoline and diesel engines—and how do results display?

The tester supports both gasoline and diesel lubricants with separate sampling modes, so readings better reflect each oil type’s properties. Results appear as an analog bar graph plus a symbol and audible prompt to indicate condition at a glance.

• Separate gasoline/diesel modes for more accurate interpretation
• Screen shows transmittance percentage and temperature
• Symbols: “OK” (60–100%), “!” (30–60%), “×” (below 30%)
• Audible beep accompanies every result for immediate attention

How do I test oil safely and reach the sample when dipstick holes are deep?

The KAISAL tester includes a 1270 mm (50 in) PTFE probe that bends to reach deep dipstick tubes without removing oil. The probe’s oil-resistant construction and integrated sensor enable in-vehicle sampling when engine temperature is within recommended range.

• 50-inch flexible PTFE probe resists oil, oxidation, and corrosion
• Integrated sensor at probe tip for in-situ measurements
• Guidance: run engine for one minute to circulate oil, test only below 60°C
• Option to remove a sample bottle when probe depth prevents immersion

What features make the tester convenient for DIYers and shops?

KAISAL designed the unit for one-handed operation and real-world garage use: non-slip grip, backlit buttons, auto power-off to save batteries, and a durable probe. The package includes batteries and a three-year product service commitment for support.

• Lightweight, handheld body with non-slip silicone grip
• Backlit button and 2.8" LCD for low-light work
• Auto power-off after 5 minutes; powered by 4x AAA (included)
• 3-year product support from KAISAL for technical assistance

Who is this for? The KAISAL Engine Oil Tester is aimed at vehicle owners who prefer data-driven maintenance, independent mechanics, and fleet managers seeking quick checks across many vehicles. It’s also useful for hobbyists who change their own oil and want a fast, repeatable way to monitor lubricant condition without sophisticated lab equipment. Follow the included usage notes—keep engine temperature below 60°C, wipe the probe clean, and shake bottled samples—to get the most accurate readings. With its long probe, audible alerts, and clear display, this tester helps you make timely oil-change decisions and avoid unnecessary service or missed problems.
