Classic Oil - The original No-Toil air filter oil:
Water resistant filter oil
Does NOT wash out with water alone, gas or solvents
It will amaze you how quickly and easily your filter will come completely clean with No-Toil air filter cleaner and water
The filter will be super tacky and ready for use quickly due to the alcohol carrier
Evolution Air filter oil has all the great dirt stopping tackiness and high air flow characteristics as the original No-Toil Filter Oil, but without the alcohol. Evolution is compatible with any brand of air filter and, without the alcohol solvent, the foam element will last longer and glue seams won't delaminate. Evolution is compatible with the original No-Toil Filter Cleaner and cleans amazingly easy and quick and will shock your senses with how clean it will get your dirty filter. For the oil to tack up, it may take as long as five or more hours. No-Toil recommends letting it set out overnight before use.
