Nice little help for my old car
Maybe not exciting, but this Rislone zinc treatment was a thoughtful gift from my son for my 2008 Corolla. I poured it in during an oil change and the engine idle smoothed out a bit. the small yellow bottle is easy for my hands to hold. I’m glad the car sounds less “ticky” now.

Oil additive that calmed my engine
One of my coworkers swears by this stuff, so i grabbed a bottle for my old Corolla that I drive home after night shifts. Engine was ticking on cold starts and it bugged me pulling out of the hospital lot. Poured this in at my oil change and the next morning it was way quieter, which honestly made me glad I tried it bc my commute felt calmer.

Good for Older Harley Engine
A bit of added protection on standard automotive synthetic engine oil. Not for wet clutch or engines with catalytic exhaust systems.

Protecting small engines as well as older vehicles
I was unaware of the fact that modern SAE oils that have been used in lawn equipment, 4 cycle engines, can be damaged due to the lack of Zinc in the formulations that have been marketed since the 1990’s. As I live on a small acreage I have many lawn tractors and lawn movers plus generators, power washers, trimmers, etc. I restore others that I purchase locally. Seller shipped promptly and arrived in great shape.

Has what old engines crave
This lets me use regular modern 5w30 low zinc oil in an old 80s 350 engine without having to buy different types of oils. Follow label instructions, do not over dose.

Creates a lubrication film per instructions
I filled suggested amount per instructions. Used a syringe, on my 2015 corolla. Noticed, my idling dropped from 1000rpm to about half ,600rpm combined with a lower viscosity 0w16 oil. Although, it's not a large sample size. I can say, it does work, per my vehicle.
