Key results

↑4-10.9%

compression by cylinder, 1100-1250 → 1220-1350 kPa

↓11.5%

fuel consumption at idle, 700 ml in 29 min 37 s → 33 min 27 s

↑19.2%

top speed in 5th gear, 130 → 155 km/h

WHAT WAS TREATED	MILEAGE AT TEST START	DOSAGE AND WHAT WAS MEASURED
22R engine, 4 cyl., carburettor	415 857 km	3 tubes of 9 ml per 4 l of oil — compression by cylinder, fuel consumption, oil top-up rate, spark plug condition
5-speed manual gearbox and rear axle final drive	415 857 km	2 tubes and 1 tube of 9 ml per 3 and 1.5 l of oil — top speed in 5th gear, noise and vibration

Compression by cylinder, kPa

CYLINDER	700 KM	1 940 KM	3 560 KM	CHANGE OVER THE DISTANCE
1st	1100	1050	1220	+120 kPa · 10.9 %
2nd	1225	1290	1350	+125 kPa · 10.2 %
3rd	1250	1300	1300	+50 kPa · 4.0 %
4th	1180	1250	1300	+120 kPa · 10.2 %

The count starts from the first measurement taken 700 km after the revitalizant was added: compression kept rising over the whole observation distance, up to 3 560 km.

Fuel, oil and highway performance

PARAMETER	BEFORE	AFTER	CHANGE
Time to burn the reference 700 ml at idle	29 min 37 s	33 min 27 s	consumption −11.5 %
Top speed in 5th gear	130 km/h	155 km/h	+25 km/h
Oil top-up: first 1 000 km → next 940 km	1.0 l	0.5 l	−0.5 l

Fuel consumption was measured by the time taken to burn the reference 700 ml; the report's conclusion states a reduction of 12 %. Speed — on one and the same stretch of highway.

Condition of the units: before treatment and after 1 940 km

WHAT WAS INSPECTED	BEFORE TREATMENT	AFTER 1 940 KM
Spark plugs of cylinders 1 and 2	Dry	Dry, clean, brown-grey deposit
Spark plugs of cylinders 3 and 4	Oil-fouled	Dry, brown-grey, no traces of oil
Engine running	Rough, crankshaft bearing noise audible	Smoother and quieter, response and acceleration improved

For the treated manual gearbox and rear axle final drive the report records reduced vibration, especially in neutral.

Conclusion of the report

Following the application of XADO technology to a TOYOTA pickup, the service company REDLINE PERFORMANCE confirms: 1. Fuel consumption dropped by 12 %. 2. The engine runs smoother and quieter. 3. Oil burn-off decreased. 4. Top speed in 5th gear on one and the same stretch of highway rose from 130 to 155 km/h. Before treatment the engine, with 415 857 km on the odometer, ran roughly, crankshaft bearing noise was audible and the plugs of two cylinders were oil-fouled — after 1 940 km the working surface of every plug was dry, with no traces of oil. Compression gained 4-10.9 % across the cylinders and kept rising to the end of the observation: the restored sealing of the cylinder-piston group is the very reason for both the added performance and the fuel saving. All of it obtained without disassembly, on a vehicle in ordinary service.

The results relate to the 22R petrol engine of a Toyota pickup with over 415 thousand km on the odometer, its manual gearbox and rear axle final drive; on other units and under other operating conditions the figures may differ. The original report is published in full and available for download.
