Kschachn,
I'm not going to argue and go back and forth with you....but Mobil 1 is $24-$28/gallon at my local Walmart, depending if you buy "regular", AFE, EP, etc.
People have shown UOA's with RLI and they have all been good results. No one has reported any engine damage or failure as a result of running RLI either. As far as piston deposits and such go, I have no information or data on that. But this oil is very stable. It's always been reported to have the proper viscosity....it seems to be shear/dilution proof and I've never seen a hint of oxidative thickening either reported.
