Oil and fuel additives

[bretttennar]

What are the reasons you would use or not use fuel and oil additives. I just purchased a motorhome and want to take care of it. Thanks

I use fuel stabilizer as this new blend ethenol has a shelf life of nothing. Cheaper than repairs. I also use, with amazing results, a product called "Sea Foam" in gunked up carbs. The stuff is amazing and does all it claims

With a diesel, there are two times you want/need an additive:

If storing the fuel over 2 months in the summer or 3 months in the winter, add a BIOCIDE to keep algae from growing. Biobar JF is a common one.

If you fill up in summer or fall and will be keeping the fuel into winter (with below freezing conditions) add an anti-gel. PS brand is stocked in most Walmarts. If filling in winter, the fuel already has been formulated so it will not gel.

Also, be sure to store your diesel tank FULL to minimize condensation.

Others can probably advise on "care and feeding" of your DEF.

You really need to give us more information for us to be of assistance.

Advise on diesel fuel additives are of little value if you have a gas coach.

Gas or diesel

There are alot (additives) on the market do you just feel they are not needed?

I would not use any oil additives. Just use a good grade of oil as recommended by the manufacturer.
The only fuel additive I would use would be a fuel stabilizer in a full tank of fuel if I was going to let the coach sit for a period of time. Before doing that I would run the stabilized fuel through the generator to make sure that it is protected as well.
Some people like to use an injection cleaner fuel additive but I have never felt the need.
