Engine treatment ’RVS-Tech’
I bought the Rover V8 P6B in 2014. It was running fairly ok but running only a little above 6km/l. The car had gone probably 200.000 km. I decided to do a detailed analysis of the engine including the ignition, spark plugs, compression ratio, carburetors and mixture.
First I noticed the spark plugs condition, they were very uneven colors, most black. Compression ration might not be even then. The engine is stated to a CR of 9.25:1 then the CR test should read above 9.5kg, on a hot engine.
Doing a CR test using a calibrated CR meter and 12 strokes per measurement, the figures was in the range from 8.5 to 10.3 kgcm.
I have heard about ‘RVS-Tech’ that should give a deposition of metal ceramic layer of worn surfaces and thus increase density and reduce friction.
I decided to try the RVS-tech product G6 for petrol engine.
RVS Technology® is a technique that has the capacity to form a Triboceramic surface structure on metal friction contact zones (metal-ceramic), while the mechanism is in its normal productive operation. RVS has unique properties; it protects and prevents the surfaces and mechanisms of wear and tear. RVS is the only technology that has the ability to restore sliding surfaces, in good case, up to their original shape and tolerances. The new surface structure takes place autoreactively, without disassembling the equipment being restored. In practice this means, without down times and loss of production…
Fine words but let see by testing and analyze in a detailed way.
Km/l measurements, averaging. Compression measurements before, spark plug color before, Wideband Air Fuel Ratio (AFR) installed. Engine Treatment with ‘RV-Tech’, Compression Measurement at + 400km after the first treatment. Oil Change 2nd RVS treatment then + 400km, 2nd compression measuring and AFR mixture adjustments, then new km / l measurements and averaging.
As seen on the bar graph and table, the CR got up from the range 8.5-10.3kg to 9.6-10.6 after the first treatment (+19%), 400km. After the second treatment, +500km, even two more cylinders got up in pressure. All together a fairly impressive improvement that should last up to 100.000km without affect by oil change.
