Tough Starts and rough idle

Has it been harder to start your car lately, particularly in the morning? And when it’s finally running, does it idle rough? A dirty fuel system and/or clogged injectors could be preventing an even flow of fuel to your engine.

Wondering why your car isn’t getting the gas mileage it used to? There may be deposits clogging your fuel intake system. These deposits will make your engine “work harder” to get fuel, which will in turn hurt performance and gas mileage.

Lost Performance And Power

Is your car’s get-up-and-go a distant memory? Is it hard to start, hesitating and/or stalling? One of the most common issues are deposits that accumulate in your fuel system and restrict fuel flow. There is roughly 109a ethanol in most of the gas we use today, and ethanol-blended fuels can create deposits that clog the fuel system.

High Mileage Vehicle Maintenance

Is your car approaching or over 75,OOO miles? If so, then you’ve probably noticed a drop in performance. Time, miles and internal engine friction take their toll. Even your engine’s seals and gaskets can dry out, which can cause leaks. Proper maintenance can help avoid these issues and keep your car in it for the long haul.

Maintain your vehicle with:
STF High Mileage Fuel Injector & Carburetor Treatment
STP High Mileage Oil Treatment + Stop Leak

Lost Power Steering

When you turn your steering wheel sharply, do you hear a groaning sound? That’s a sure sign of low power steering fluid, so check for leaks. Also, power steering fluids contain oils that can oxidize. When that happens, its ability to flow and protect internal parts is compromised. Check your manufacturer’s guide to see when to change your power steering fluid.

Keep your power steering performing with:

Fluid Leaks

Is your car getting up there in years/mileage? If so, you may begin to see fluid spots on the ground underneath where you park it. You may also notice an oil-like smell when the engine gets hat. Over time, engine gaskets and seals dry out, and can cause fluid loss.

Help recondition gaskets and seals with:
STF Engine Stop Leak

STP High Mileage Oil Treatment + Stop Leak

Excessive Engine Friction

Have you noticed a drop in performance lately? The moving parts in your engine operate under very tight tolerances. As mileage increases, excessive wear and friction can occur. This metal-to-metal condition could hurt your engine’s reliability and overall performance.

Guard against excessive friction with:
STP Synthetic Oil Treatment
silver fuel bottle

Excessive Oil Burning

Are you seeing a cloud of greyish/bluish smoke behind your car when you start it up in the morning, or when you accelerate or decelerate? You could be burning too much oil, particularly if your engine has over 75,000 miles on it.

Help reduce oil burning with:

Exhaust Emissions/Smoke

Has there been more smoke than usual coming out of your exhaust system? The combustion chamber in your engine is designed to burn a mixture of air and fuel. That’s it. As your mileage increases, oil can contaminate the combustion chamber. This condition, known as oil blow-by, often results when friction and metal-to-metal contact have worn parts and created gaps between the cylinder walls, piston rings and valve guide seals.
