I have used NoToil for over 3 years with ZERO problems. It's easy to apply, easy to clean ( the cleaner works great in your washing machine or sink, leaves no residue, non-flammable, safe for skin, safe for environment). As far as being "tacky"... the oil combined with the filter traps the dirt..period. All tacky oil does is restrict air flow, is a hassle to clean, and generally makes a mess. Using NoToil may have an effect on your jetting because it will flow much more air due to thinner oil. I also use their filters, here is a suggestion: use only NoToil products with NoToil filters..I do know a race team that used "Brand X" oil & cleaners with NoToil filters and experienced delamination problems with the filters. NoToil works great, they support our
