I have a 96 b2500 van. I was told not to long ago, that with every fill-up i should put some gas cleaner to the tank. i have bought a few different ones, was wondering what would be the best to use? if i should use it at all. same question for other stuff i see. Like the stuff to add to the radiator or oil? any help appreciated. thanks

 

Never hurts to run a can of fuel system treatment every few months. Every fill up? No. Engine oil and other additives are not required.

 

Nope don't do it. Twice a year dump a quart of lacquer thinner in the gas tank before filling it and that will do all the fuel system cleaning you could possibly need, the catalytic converter too.

 

Running Top Tier gas will help keep everything clean. Some of the popular gas treatments are Gumout with Regane,Seafoam and Marvel Mystery Oil.

 

I own a 1972 Triumph Tiger motorcycle and the fuels leaving the least amount of deposits, that is, the cleanest fuels out there are unleaded premium gasoline from both Shell and Chevron.

As someone stated lacquer thinner although I haven't tried using it. Seafoam seems to work quite well.

 

Seafoam is mostly kerosene.

 

Seafoam smells more volatile than kerosene. The former smells like acetone to me and I have an extensive background in chemistry. And so how do you know that Seafoam is mostly kerosene???

 

Read the label on the bottle.

 

That answer made me darn near choke on my coffee this morning!!! lol funny!!!

 

We're all here to learn. Over the decades Techron has sometimes been the additive of choice.

Just as there are several grades of kerosene and jet fuel, there are several kinds (around 25) of Naptha. It's the Naptha (an ingredient to napalm) along with the alcohol that I'm smelling:
