Helps save my motors
This product is a must for preserving newer motors. Without this additive, camshafts can wear down prematurely.

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.

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.

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.

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.
