ok I didn't know if you meant that it was mechanical or not. It is electric. It increases and decreases oil amounts through the computers program. It MAINTAINS a flow rate through it's volume so it can't change it's flow rate. That's what a positive displacement pump is. As to the SDS (MSDS here; Material Safety Data Sheet) That just show safety data in case of emergency, That doesn't tell you what is in it as a formula. Cats formula for the oil is not Cats responsibility to competitors for the formula. They can give a spec that it has to meet. But thats all. If they deny everything (which they never have) thats when the law suits fly. And this never happened.Who said the pump was mechanical and not electrical? Not me. The pump would be a positive displacement pump controlled by an electric motor. Huge swings in viscosity would change the flow rate of the pump. When they are already injecting less oil, the amount injected is critical.
Cat published an SDS as required by law but they don't have a specific test standard the oils must meet. Many of the oil companies have done testing and showed their oils worked just fine in CTEC2 engines. On the flip side, I have seen no documented engine damage proven to be due to the oil when a high quality synthetic is used.
I run the Cat oil as I find the price is reasonable, it is easy to get, it smells good, and the low temperature properties are good. My engine spent the first 1,600 miles of it's life on Amsoil Interceptor. I have zero concerns of any engine damage due to the use of Interceptor. The cylinders, pistons, and rings looked flawless. Power valves only had the normal carbon buildup but still actuated fine.
Only thing that happened is Amsoil just SAID it was was ok to use. People put it in their own sleds and SAID everything was fine or "my power valves were clean" or " I have zero concerns of any engine damage due to the use of Interceptor."
All this may be all just fine and happy But,,,
Again to new buyers. These are all just people saying this stuff. There is no test done for approval nor was any other oil ever approved by Arctic Cat to meet the specs of the Ctec2 engine PERIOD!
