Tech Tip:  
  
Always add a quality fuel stabilizer like [Sta-Bil 360 Marine](https://parts.docsfullboreoutdoor.com/collections/lubricants/products/22239) to all fuel being put into your tank to prevent ethanol gumming and varnish.  The #1 repair for dealerships is old fuel related issues.  Stabilizing your fuel can prevent most issues for up to 12 months.
