Running B20 recently, do I need to change my filter?

Hello,

Sorry for the noob question but I did not have luck with searches. I know bio starts to loosen things up in your tank. Does this go for b20 as well?

Thanks!

Filter clogging is close to an urban legend, especially with B20.

I'd keep a filter handy with any kind of fuel I was burning although.

B20 will not loosen things up. It has to be in higher concentrations.
