questions on adding diesel additive "diesel kleen + cetane boost"?

Question

the bottle is 32oz.
The only instructors it says is:

Cetane Boost 32 oz. Treats
3 Numbers.................100 gallons
6 Numbers...................50 gallons

What is the difference between 3 and 6 numbers? My tank is 22 gallons. So I should bring it to almost empty, and then put how much of this stuff in before I fill the tank?


My car also had this weird problem of the engine turning off when idle (radio stayed on). A guy suggested to me could be water deposits in the fuel tank. I got this cheap stuff called "Heet, gas-line antifreeze & water remover". The guy told me to put the bottle in the tnak before I fill it up for the next two fill-ups.

On the back it says 'do not use with 2-cycvle gas or diesel engines, use Iso-HEET instead" - what is 2-cycle?

my car 1991 mercedes 350 sdl.

Thanks appreciate any help_)

would it be in the manual on how to drain the water from the fuel filter?

Yeah I looked closely on the back of the HEET bottle it says USE WITH GASOLINE ENGINES. The guy at autozone seemed to know a lot about diesel i dont know why he gave me the wrong bottle then.


So as for the Diesel Kleen+ cetaine boost , go for the 3numbers (whatever that means) - a lower ocncentration. Says for 3 numbers 32oz. treats 100 gallons, so that would mean if my tank is 22gal use about 7-8 oz. of this stuff?

Answer 1

Have you noticed that an Owners Manual to every Mercedes car says: "Do not use fuel additives, they do not do anything and may damage the engine."
I tend to agree. There are additives for "every problem." If they worked, we would never had to FIX cars...

Answer 2

When in doubt ask a service station manager or a trucker. It has something to do with the fuel. I never use it.

2 cycle is chain saw motor and lawn mower motors that take a gas/oil mixture fuel. Those are the engine that are always blowing "blue" smoke. Also used on leaf blowers.

Get the Iso-Heet. Good thing you caught that.
Water deposits in the fuel tank....more likely that the fuel filter needs draining(water will be collected in there). Should be under the hood and have a little valve underneath which you open every 6 months to get rid of water that is in the fuel.

Answer 3

If you are uncertain then go for the lowest concentration as that will ensure you do not damage your fuel pump as that is an expensive repair.

2 cycle is a 2 stoke motor, try reading this
