A springer NEEDS a little dieseling to be efficient.Having said that you do not get dieseling from oil in the barrel.You get dieseling from oil in the compression chamber.
The only way to use cleaning pellets in a springer is to load a pellet behind them..
I have used cleaning pellets in my springers for 30+ years...Four at a time..with dish soapAbout 12 of them.Then four dry ones..
