Toyota pickup 22R engine: compression rose with mileage, fuel consumption fell
Piston-cylinder group regained seal, the engine became more economical and gained speed. 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 (2003).

Key results
| 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.
