The Dynamic Duo: AMSOIL P.i. & Upper Cylinder Lube

Let me end the suspense – there is no magic bullet when it comes to vehicle maintenance. Keeping your engine in top form requires more than one tool in your toolbox. Enter the one-two punch of AMSOIL P.i.® Performance Improver and Upper Cylinder Lubricant.

Consider your pearly whites for a moment. To avoid a painful situation, you make the pilgrimage to the dentist’s chair a couple times a year and brush your teeth as much as possible between visits. Cut out half that equation and you’re asking for trouble.

Inside your engine, P.i. plays the role of dentist – the deep clean. Upper Cylinder Lube is your daily brushing – the keep clean. It’s a comprehensive strategy that helps keep your engine running smoothly.

What’s the problem?

P.i. and Upper Cylinder Lube work in tandem to address common issues many drivers encounter.

• Decreased fuel economy
• Increased exhaust emissions
• Power loss
• Poor starting and rough idle
• Pre-ignition “knock” or “pinging”

P.i. hits these issues head-on with concentrated detergents that aggressively clean stubborn, power-robbing deposits. Upper Cylinder Lubricant preserves and builds upon those gains. It maintains cleanliness (particularly the all-important fuel injectors), provides supplemental upper-cylinder lubrication and fights ethanol-related corrosion.

Two steps for a clean and protected engine

Step 1 – Deep clean with P.i. Performance Improver every 4,000 miles

• Cleans fuel injectors, intake valves and combustion-chamber deposits
• restores up to 14% horsepower¹

Step 2 – Keep clean with Upper Cylinder Lubricant in every tank

• Lubricates upper cylinders to fight wear
• Inhibits ethanol-related corrosion
• Keeps injectors clean
• Delivers 18% more lubricity than Lucas*² and 20% more than Sea Foam*² for better retention of horsepower and fuel economy

How P.i. deep-cleans your engine

AMSOIL P.i. attacks carbon and sludge buildup head-on with concentrated detergents that aggressively clean stubborn, power-robbing deposits from injectors, valves and the combustion chamber. Third-party testing demonstrated the performance of P.i. using a 2016 Chevrolet* Silverado* with 100,616 miles (161,926 km) on the odometer. Following a single treatment with P.i., the truck measured a 14% improvement in horsepower.¹

P.i. helps keep valves clean and moving freely; helps protect against compression loss, difficult starting and rough idling; improves fuel economy and helps restore power and performance. It also reduces the possibility of both “carbon rap,” when deposit buildup causes the piston to hit the cylinder head, and pre-ignition “knock” or “pinging.”

AMSOIL P.i. is effective in one tank of gasoline. Simply add the entire bottle to the tank at fill-up and let it go to work. We recommend treating vehicles with AMSOIL P.i. every 4,000 miles (6,437 km).

How Upper Cylinder Lubricant keeps it clean

AMSOIL Upper Cylinder Lubricant helps preserve and build on the gains made by AMSOIL P.i. It maintains cleanliness, particularly in the all-important fuel injectors, lubricates the under-lubricated top end of the engine and fights ethanol-related corrosion. That’s important because an engine’s top end is sparsely lubricated and prone to the development of deposits. It’s also highly susceptible to corrosion, an issue compounded by the prevalence of water-absorbing ethanol in fuel.

It may seem surprising that a vital region inside modern engines could lack lubrication. But the intense heat of combustion and limitations of the oil-control piston ring result in a lack of oil at the top of each cylinder. Upper Cylinder Lubricant deploys unique additives to provide that missing lubrication and reduce piston-ring and cylinder wear – maximizing engine compression and horsepower. Its lubricity improvers also aid in protecting fuel injectors and other fuel-system components from wear.

AMSOIL Upper Cylinder Lubricant delivers 18% more lubricity than Lucas* and 20% more than Sea Foam* for better retention of horsepower and fuel economy.²

To battle corrosion, Upper Cylinder Lubricant uses potent corrosion inhibitors that coat metal surfaces, block out moisture and stop deterioration before it starts. This is particularly important when using gasoline that contains ethanol due to its ability to absorb water.

We recommend using Upper Cylinder Lubricant with every tank of fuel. Simply add the entire bottle to the tank when filling up and it will do the rest.

Any questions?

Can I use both P.i. and Upper Cylinder Lubricant at the same time? Yes. Both products can be used together in one tank of gasoline.

How frequently should I use P.i. and Upper Cylinder Lubricant? P.i. should be used every 4,000 miles as a deep-clean. Upper Cylinder Lubricant can be used every fill-up.

Do I need to use P.i. and Upper Cylinder Lube if my vehicle is new? We recommend using AMSOIL gasoline additives throughout the life of your vehicle to preserve like-new power and efficiency.

If you choose to use gasoline additives, consider the dynamic duo of P.i. and Upper Cylinder Lube. This complementary approach helps clean and maintain critical fuel-system components.
