 Subject: What kind of gasoline do you use?
IP: Logged
Message:
Hi guys,
I have a 96 Dodge Dakota,3.9L,Automtic Trans. (I have had this truck for two months so I still learning about it)
My truck has a weird knocking sound that it seems is getting lauder and lauder everytime. I know it could be many things but I was reading the repair manual and it suggests that sometimes using a higher grade of gasoline can help to deminish the knocking sound on V-6 Magnum engines.Righ now I am using regular gasoline.
So I thought I would post this question to get your imput:
What kind gasoline do you use on your trucks?
Do you think a higher grade of gasoline will improve engine performance?
Please let know what do you think.

well a knocking noise can mean many of things.... bearings going bad on the rods or on the mains.... now if you a pinging noise like the timing could be off or what they call spark knock to do the timing being to advanced then a tune up or just plain timing check could be needed.... from the factory the trucks are programmed to run on 87 Octane.... i got a 99 dakota and thats all i use.... ive seen at one point in time where i did use higher grades and my fuel got worse by a few miles but didnt notice any change in performance.... unless your running any kind of forced induction you dont need to use the higher grade fuel....

I use the lowest octane i can possably run with out pinging and right now its the cheap stuff.
Ive noticed i get a mileage drop using higher then needed octane.
If urs is pinging and it wasnt before it may be a bad belly pan gasket or it just needs the carbon cleaned out of it. A simple cup of water trickled into the TB works for carbon or u can use seafoam and do the same. It could be other things causing pinging but i mentioned the easy to check stuff first.

the water trick isnt the best idea for that.... for someone who's not sure on how much to trickle in canr eally do damage internally... water cant be compressed under the same conditions the air fuel can be cause water cant flash off from heat... trying to compress water in motor can bend a rod in a blink of an eye and it doesnt take much for that to happen....

Its safe to do just as long as nobody goes WOT and sloshes a 5 gal bucket in it.
Ive seen motors damaged from water. what happened to them was they got the snorkle in the water and it essentially was like taking a vaccuum cleaner hose and sticking it in water where nothing but water was being sucked in. Rods bent heads cracked cranks snapped not pretty.
What ive done is trickled water in at an idle once engine is fully warmed up of course (since the vapor does the cleaning) and eventually i work my way up to WOT using the water to control engine speed. I havent messed a motor up yet and i have been doing it for a long time. Seafoam is no safer thats a liquid also and can not be compressed. A leaky injector can also fill a piston with fuel and ruin a motor when u go to crank it. With water ur adding a non flammable mixture and in vapor form, 1 cup of water is usually enough to clean a motor.
Just dont think that when i sayed trickle 1 cup of water it really meant grab the garden hose and let her rip.

Are you sure its not the timing chain
let it idle bend down like your looking under the
front bumper and listen
If it is replace the chain and gears and use the
tensioner and the noise will be gone
on the home page of this site you will find in
the how toos all about this

I don't know why you guys don't seem to think a higher octane fuel makes a difference. I use my '99 Dakota 3.9lt 5 speed manual to both plow snow(Blizzard 720LT) and to pull my 21' boat. There's a huge difference in power and performance with 92 versus 87 octane. Don't listen to these guys telling you to put water in your engine, that's retarded. Try the 92 octane, if it makes your truck run better go wuth it.

Water has been used on a regular basis as a triffic carbin cleaner all the way back to the Model T Fords. There was no other cleaners in those days. I've used it a lot and I will swear by it. It basicly steam cleans your pistons, valves and heads if they are carbined up. I use a squart gun to do it down the throttle body. Kick it up to about 15 to 18 hundred RPM and go for it. The worse the carbin buildup the more times I load the squart gun. Long as you don't dump a chit pot load in there you well do nothing but good. This was/is a terrific repair on old tractors/farm machinery that had no thermostate and no water pump. they run hot/cold all day long every day and carbined up really bad.
To the guy using High octain gas and getting lots of power from it. With all due respect It can't happen unless your engine is built up to use it . Stock Dakotas are not. The higher the octain, the SLOWER the burn. You lose HP and fuel milage. These are facts, not my ideas. Do as you think correct. Your money.
