Thanks to you guys I got the tank all cleaned out, no more water nor white sludge, Clean Clean.<br />Now what octane gas should I use and should I use an additive . Tank is 22 Gal plastic, motor is oil injected. How do I make sure this water/ sludge in the gas tank doesn't happen again.<br />Thanks To All Who Advised. JarHead-8 In The Swamps...
