Once your vehicle shows red signals like rough idling, hesitations, start-up troubles and dirty emissions that could trigger engine service lights, it could mean that your injection system and its neighboring parts could be clogged (Please check our homepage for the best fuel system cleaning solution).
- Modern gasoline blends
While the Clean Air Act Amendment required deposit-control additives and detergents in the Top Tier fuels to lessen levels of higher hydrocarbon and carbon monoxide in vehicular emissions, these blended compounds also build up and harden over time within the heated petrol system.
- Percentages of ethanol in benzine
Even ethanol percentages in modern petrol add to the carbon deposit in the petrol system. Ethanol sucks the energy out of your petrol after it condenses into vapor once the engine has cooled down. The product is water trapped in the petrol system.
If I use quality gasoline, what else can I use to remedy/prevent this?
- Off-Car Cleaning
This entails the removal of the injectors and submerging them in an ultrasonic bath along with other flushing methods to clean off dirt and gunk build up. This method can be tedious and is best left for professionals or experts to tinker with.
- On-Car Cleaning
This method utilizes a benzine injector cleaning kit where the kit is connected to the petrol system and flushes out deposits and other debris through a burst of pressure. This method is risky especially for amateurs since it uses a flammable solvent at high pressure while the engine is turned on.
The simplest remedy, petrol additives are meant to be poured into the tank either as remedy or preventive measures. This has been my key to preventive maintenance for my 2002 Subaru WRX. Every time it acts up after a few thousand miles, I put in a can of cleaner in a quarter of my tank. And if my family and I ever do go on a road trip that requires hours of driving, I put some of the best cleaner in when I fill up. My usual mix is three-quarters petrol and a can of the cleaner.
BG 44K – A Real SUPER-STAR as the best model, BUT just for GASOLINE engines only
I’ve tried the BG44K myself before heading into an 8-hour drive. I was told that once the solvent was in, it was better to run the tank and not let it sit in for hours (which I did). Apparently, my drive felt smoother and I had no engine trouble throughout.
My buddy who owns a 1967 Falcon he uses for racing puts in half a can of the BG44K with every 5 gallons of race petrol. He started using the product after he noticed leaks in a few cylinders.
He ran a full can in 10 gallons of race benzine and noticed that the leak numbers decreased and are now constantly below 3%, including compression numbers that are now back to normal.
In my quest to find the best cleaner for my car, I also tried the Chevron Techron brand. What my mechanic told me before I used this product was not to go overboard. The recommended dosage is a bottle (about 20 ounces) for 20 gallons of benzine for 3,000 miles meant for maintenance.
Do not use more than the recommended dosage since the product is pretty strong and will eat into rubber and plastic parts in the benzine system including the interior lubrication.
However, Chevron truly is one of the best cleaners out there. I have been using it since my local shop phased out BG44K and it works like a gem on my fuel injectors.
My brother recommended this additive and swore that it was one of the best fuel system cleaners available in the market, so he got me to try it when my Subaru only had about 6,000 miles in it.
Normally my car even in its semi-new stage would start up pretty loudly (it reverberates all throughout the interior of the garage) especially from a cold start. I filled my tank with the recommended dosage of 2 ounces of cleaner per 10 gallons of benzine.
The following mornings, my start-up was much smoother. It didn’t make as much noise as usual. My brother’s 2008 Ford Escape has been maintained with this product every few thousand miles and has really helped with the occasional on-car cleaning treatments he gets at Walmart.
