Rislone 4732 Fuel Injector Cleaner with Upper Cylinder Lubricant – 32 oz

Refresh Your Fuel System with Rislone 4732

Rislone 4732 Fuel Injector Cleaner with Upper Cylinder Lubricant is designed to renew fuel-system cleanliness with regular use. The 32 oz bottle provides a complete tune-up, helping cleanse injectors and fuel pumps while adding protective lubrication for the upper cylinders. Expect a cleaner-sounding engine and smoother interaction with the throttle as routines become more fluid over time.

With this formula, the goal is to support smoother idle, easier starts, and quieter operation by combining injector cleaning with upper-cylinder lubrication. While no product can guarantee specific results, many drivers notice a more composed feel during everyday driving and improved responsiveness as deposits are cleaned away and protective film is added to critical surfaces.

Key benefits and why they matter

• CLEANS FUEL INJECTORS: This heavy-duty solution targets injector and fuel-pump chatter, helping reduce rough idle, hard starts, and hesitation while promoting cleaner spray patterns.
