How do you clean a Volvo gas tank?

Fuel system cleaner usually does a pretty good job, "heet" is a pretty good job, fuel injector cleaner cleans the injectors/carborator/gas tank/ and yeah... pretty much everything, the only thing you have to do after using a fuel additive, is to buy a new fuel filter, you would have to do that because the chemicals from the additive clean the sediment and other gunk from the bottom of the gastank, and all that crap goes throguh the fuel filter, plugging it up. A 1995 Volvo 850 Turbo Station Wagon's fuel filter is only about $15.00 at napa, and "heet" is only like $4.00 There are specific products for fuel tank cleaning. The items mentioned above are only temporary fixes and are not reliable tank cleaning methods.


What are names of fuel additives?

Don't waste your money. Fuel additives do not work. There are 2 good fuel system cleaners i can recommend. Techron, and Seafoam. Both are great products and should be used once a year to keep your fuel system clean. Forget the fuel additives.

Most likely a clogged fuel filter. If the vehicle has been out of use for a long time, it may also be due to contaminated fuel. Adding a fuel system cleaner or fuel additive such as heet, in addition to a quantity of good fuel should alleviate the problem if this is the case.

What is the best fuel additive?

My opinion is that Cerma Stm 3 is the best fuel additive. I use it on my pickup and I went from 17 to 20 mpg's. After you add it to the fuel you'll need to change your fuel filter because it does a really good job cleaning the gunk out. The website explains it in better detail than I can. To learn more about it check out related links.

Is the fuel system on car sealed or can water get into it?

It depends on what year, make and model but for the most part the vehicles built since the 1990's are a sealed/closed system. Water can get in via contaminated fuel from gas station and also a small amount can accumulate from condensation. Regular use of a quality dry gas additive is always a good idea.
