Suzuki/Cycle-Rx test

A: pre RX 2000, B: Cycle-Rx Clean 1000, C:Cycle-Rx clean 1500, D: post Cycle-Rx rinse 2000, E: Amsoil Synthetic 2000, mileage intervals. 

Protocol: Customer controlled the operating, sampling, and servicing a well maintained Amsoil 10W-40 lubricated, Fram oil filtered, K&N air filtered, Amoco 93 octane fueled, 1996 Suzuki RF900R. Bike operated primarily at East cost of Central Florida . Progressive and correlated compression testing was performed at each sampling showing normal compression levels. Test begun 3/05, ended 7/05.

During the A pre-cleaning, B & C cleaning, and D rinse phases, Suzuki OEM 10W-40 motor cycle oil was used. The E, 2000 mile interval was Amsoil alone.
Text Box: Aluminum LOW piston, bushing, casting wear, lower wear than pre RX cleaning , excellent. Text Box: Calcium Normal oil add for OEM and Amsoil formula Text Box: Chromium Normal to low ring and coating wear, amazing post RX drop to nil ring wear
Text Box: Copper Super low clutch face, thrust washer, bushing wear, cleaning bump was trans and clutch residuals scavenged by RX, see Large Particle Detection comments Text Box: Fe Trans and clutch face had corrosion that raised this value over the clean phase as the oil filter loaded. Oil filter at 1500 miles into cleaning needed to be changed. Engine was cleaned early in interval while residual clutch & trans wear materials were safely encapsulated by Cycle RX. 22% drop in fe trend for this engine was significant. Text Box: Pb Bearing wear amazingly low,soft metals protection by Cycle RX during cleaning and post RX phases. 33% drop in wear
Text Box: Mg Normal oil add, note take up in mg post RX phase, as Mg can lube clean rings and high pressure areas more effectively when clean Text Box: Mo Ring coating wear, neither the OEM oil nor Amsoil contains as an oil add. Note decreased wear as Cycle-RX lubes compression rings. Bounce back to normal levels 4000 miles later. Text Box: P Normal oil add levels
Text Box: K Scavenged potassium from engine and trans during Cycle-RX cleaning, most likely greases and fuel add residual deposits cleaned Text Box: Si Dirt ingress nil, mostly anti-foamant adds, K&N air filter used. Text Box: Na Low dirt, some residuals from transmission scavenged during cleaning
Text Box: Sn Bearing and piston alloys, low wear, post RX with OEM oil and Amsoil nil, perfect trend. Text Box: Zn Normal oil add in OEM oil and Amsoil Text Box: Soot/Solids VERY clean engine to begin with. Once Cycle-RX employed, insolubles gone, no fuel soot or solids issues
Text Box: Oxidation Oxidation rate from the oem oil run before cycle-rx indicates a clean engine but little cleaning capability of the oem oil, divide the FTIR absorbance values by 2 to get a percentage of oxidation. Max of 7% is excellent reading in any engine, let alone one being cleaned by Cycle-RX. Text Box: Nitration Divide FTIR absorbance values by 2 to get a percent. Combustion efficiency degrades during cleaning as rings are cleaned. 19% max is excellent for the cleaning interval, Amsoil interval at 8.5% is exceptional, post Cycle-RX. Note better combustion efficiency than beginning / non Cycle-RX oem oil test interval. Engine internal operating temps as measured by nitration are lower. Text Box: Sulfur Amoco premium fuels used exclusively are low/no sulfur and ring seal is excellent as indicated by the sulfur values below threshold of FTIR.
Water none at each interval | Coolant none at each interval | Fuel none at each interval
Text Box: Viscosity @ 100c in cSt OEM oil on its own shears below design grade to SAE20. OEM oil with Cycle-RX and alone during rinse phase has better vis retention but still shears to SAE 30. Amsoil is sheared out to SAE 30, vs. design of SAE 40. Good indication of what the common sump and trans/clutch/engines common sumps do to any motor oil. Text Box: ISO Cleanliness Code Indicates silt/abrasives wear in older format. Silt remains at the same 22 level over interval. Once oil is changed back to normal Amsoil that level drops from cleaning levels. Transmission wear residuals scavenging effect was tremendous by Cycle-RX. I see the oil filter loading with these silts. Excellent post Cycle-RX level after 2000 miles, just what the designers of Cycle-RX intended ! Note some of the silt and abrasives level are from clutch face wear/corrosion after many miles on the bike. Silt is also measuring basic oil adds.
Large Particle Detection Counts:
Text Box: 5u Particles 20615/25776/34044/21708/18331 Cycle-RX progressively dropped these levels. Text Box: 10u Particles Cycle-RX cleaning effect Text Box: 15u Particles Significant drop in abrasives level after cleaning. Note wear was not impacted by the cleaning level as the micelle action of Cycle-RX is effective. In-situ cleaning effect.
Text Box: 20u Particles Same effect as 15u Text Box: 25u Particles Same effect as 15u Text Box: 50u Particles Same effect as 15u
Text Box: 75u Particles Same effect as 15u Text Box: 100u Particles Same effect as 15u

Conclusion:

Cycle-RX cleaning was significant while not increasing wear rates in the common trans/engine sump. Significant drop in wear values is indicated from data. Transmission was cleaned dramatically and surprised the testers with the level of particles scavenged. Until the Cycle-Rx test and cleaning the bike has had an exclusive lubricant diet of Amsoil.  Another good reason to do periodic cleaning with the Cycle-RX product, regardless of oil brand or chemistry used. Waiting till 60,000 miles on the Odometer is too long!
