How to prevent carbon buildup?

Dont idle unless you have to, change oil when you're supposed to. Once in a while, drive it like you stole it.

 

are YOU really gonna feel that 10% power loss from a 400, 500, 600 hp engine..???

 

You aint gonna know or feel &^$ from a 10% loss in a big kitty. Or a roll over detriot Perhaps a fall down Cummins too. When you climb a mountain high enough based on boost you probably starved for horsies anyway from your turbo. (I actually prefer super or ram chargers but no one uses this much)

In a gasoline engine, the minute computer complains about mis fire you pull that spark plug. If it's coal black and cannot hardly do anything then your engine is carbon from idling too much, never really taking it out for a run or not using supplements to clear it.

The number one thing for me fighting carbon is not taking it out for a run occasionally. A fast 80 mph blaze for a couple miles in a lower gear at top end usually blows it out. (With additives of a certain type... STP's ultra every second Chevron's Techryon use in 10 gallons 93 octane gasoline. SO in about three tanks of gas to that little bit of fuel over a month its going to be in good shape. Use the plug to verify that it's running cleaner. I have a 30 gallon tank, but I keep amounts of gasoline to a minimum and use Stabil because fill times is about once every 5 years now.

 

Not idling is the biggest help. When you idle the truck will "wet stack" the combustion chamber.

To get everything cleaned out you need heat, that comes from a good hard pull.

EGR feeds carbon soot back into the intake. Depending on the year of your truck will depend on how heavy the EGR feeds the soot into the engine.

08-10 trucks had Horribly high amounts of EGR usage to control oxides of nitrogen.

11+ trucks used very little EGR because the oxides of nitrogen are neutralized by DEF injection into the exhaust after treatment.

Cetane plays a role in clean combustion also. Using high cetane fuel or a cetane improver will reduce particulate emissions, carbon.

Keeping your injectors clean will also help reduce carbon load.

On a ISX Cummins motor it's very important to exercise the motor frequently because of carbon packing issues with the pistons.
Again, it needs to be loaded hard and get some heat into it.

 

I clean forgot about the heat part. There is a wee hill up the valley a ways that's 2 miles up. I'll use that one next time I go for a run.

 

What year is your truck? Go to Pittsburgh powers website. They have something called "Dorthy" that gets installed on your truck and traps carbon.

 

That Techron is good.I tend to use Lucas because that stuff burns hot.

 

in my cars, i use to use Techron, but switched over to Lucas as well......

in our trucks, Penske forbids us to use chemicals, not even anti-gel, which is ok, cuz our fueling company has winterized fuels.

 

Slow down decreases carbon bigtime
