Rislone 4405-6PK Hy-per Lube Zinc ZDDP Supplement, 11 oz, 6-Pack | Real ZDDP Zinc Additive

Good quality product, easy to add to cars oil

I've been using zinc supplements for rebuilds for a while now, but a friend recommended trying Rislone in my RZR. I must say, I have no complaints. Rislone has a longstanding reputation in the industry, so I decided to give it a shot. While I can't be certain of its impact, the price point makes it a worthwhile addition for potential benefits. Highly recommend!

Works great the old tractor wouldn't be without it!

Extra zinc in your engine oil sounds like a good idea for air cooled motors Put a splash of this in my push and ride on mower,

Good quality material.

Great price on additive

The reason to add this to an oil change regimen is when you have a motor that has a flat tappet camshaft. Including this zinc additive to each oil change will protect your camshaft and lifters from premature failure due to changes in oil regulations that are present today. If you have such a motor I recommend this product as it will help you preserve the performance of your engine. It will help keep it running smoother with less engine noise and a lower temperature. Possibly resulting in better mileage and less leaks down the road.

Needed for classic and older cars with flat tappets.

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.

My wife and I have been experimenting with various lubes. Some we have tried have dried quickly causing a rash, some have started smoking after prolonged shaft vibration. Care is needed with this as the added zinc reduces friction so much, one sneeze and you can find yourself across the room in full flight.

Beaucoup plus facile d'utilisation que l'ancienne formule

Just fine

Use this in my ram
