I see you have the 1.6L engine...... me too!
It takes much less than 5k miles for that little engine to get carboned up if you don't drive it like it was designed to be driven.
It's the smallest engine that Kia makes for the Soul, so thus it also has to be the most High Performance.
There is a Rev-Limiter built into the ECC so you cannot over-rev the engine. It's physically impossible.
So to keep it from getting carboned up, DO let it hit the Rev-Limiter every few days.
I did a lot of racing in both cars and motorcycles as a young man and the Need For Speed has stuck with me.
I'm still a very aggressive driver, even at 71 years old. I find that Gertrude (my Kia Soul) always runs better after a ROMP
on the Interstate.
On the second day after I drove Gertrude home from the Dealership, I had to make a run into town, 20 miles away.
Coming home I ran Gertrude up to 110 mph, on I-75, just to set the pace and get her used to running hard and fast. She's been
a real Road Runner ever since. Beep! Beep!
Gertrude always runs smooth as silk, burns NO oil and makes NO Smoke.
With each 3K oil change, I add a bottle of "Techron" fuel system cleaner to the gas tank. That keeps the Fuel Injectors clean.
And I also add about 8oz of Prolong anti-friction additive to the crankcase. That greatly reduces friction in the engine and promotes
longer life, cooler running and improved performance.
With such a small engine powering a car the size of the Soul, it needs all the help and TLC that we can give it.
Driving it SLOW is probably the worse thing we could do to that engine.
Happy Holidays Mates!
