Litmus and gas tank tests for bacteria?

[pisymbol]

Fleet guy told me that every year you should litmus test your coolant and test for bacteria in the tank? I never heard of this before.

Do you guys do this every year?

When I used to work on cranes and heavy equiptment we used to do a litmus test on them and then add sca's to them. but I dont think bacteria had anything to do with it. I know algea can grow in the fuel tanks though. never seen it in an over the road truck but have seen it emergency generators that sat to long

Yea, I mean a road truck. Apparently the guy said on the 2011 there is some kind of light that tells you to add DEF (I think that is what he said).

Sorry diesel is new to me but I'd like to join the club...I am trying to buy something that will be covered and last for years and years...

One of the disadvantages of USLD is it seems to be more prone to draw moisture. I don't have any documentation to back up my claim, but my fuel supplier is one of the sources.

There is an algeacide fuel additive to combat this problem. A good friend of mine was here this morning and we were talking about this very issue. They had a "bug" problem with thier fuel a couple of years ago. The problem is once the algeacide has done its job you still have to contend with the dead carcasses in the fuel system.

Luckily I have not had to deal with this issue, just try to consistently use good fuel and keep your tank full to drive moisture out.
