Hi
As to diesel fuel treatment, it is a investment that will involve the operation and reliability of your backup power engines and vehicles. The fuel is expensive so don’t cheap out on the fuel treatment. You need to have a diesel fuel maintenance program in place,
1. Treat the fuel with the proper required [stabilizing and antibacterial] chemicals.
2. Clean and polish the fuel once a year, pump the water & sludge out of the bottom of the tank. A clogged fuel filter is a serious problem.
A cheap cleaning rig can be home made, [consisting of] two filters a 20 micron and a 4 micron bought off eBay and a pump and some gauges. This can be offered to another family for a rental fee.
3. Send out a fuel sample to a lab for testing every year or two. Order a test kit online.
I worked for a telephone company doing backup power systems nationwide for years. Caterpillar provide me with a company that provides good products. I would not go dumping anything into my generators I was not sure of or was not approved by the manufacturer- TEN-32 is the product I used. Check out their web site and e-mail them questions.
You have a great blog, I try to support the advertisers, too. Thanks, Ed S.
