Sample from new 200 hour $300k excavator getting fuel from a local card lock station. Two mechanics headed out on a Saturday to diagnose, and they finally took a fuel sample

Fuel sample taken from bulk tank. Tank was professionally cleaned (polished) then started Cleanboost regiment with each fuel delivery.

Fuel after 8 years treating each delivery adding Cleanboost to keep microbes (black slime) from returning.
​Fuel delivery driver stated guarantee water and microbes in each fuel delivery its the nature of diesel.
​The user has to take ownership of tank hygiene to keep the bugs away.

R99 Renewable Diesel has entered the market.
Made from palm, vegetable, and cooking oil French fry and onion ring carcasses included lol.

Tank not cleaned prior to switching from Bio diesel to R99.
R99 (Renewable Diesel) has great cleaning properties but when mixes with microbial growth (black slime) this is formed.
