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), pinpoints the sparsely lubricated top-end 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
- Reduces emissions and increases fuel economy up to 5.7 percent¹
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 percent more lubricity than Lucas² and 20 percent more than Sea Foam² for better retention of horsepower and fuel economy
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. Unlike competing fuel additives, this combo works.
