About Hy-per Lube by Rislone ZDDP Supplement (4405-6PK)
Overall Feedback:
76% positive
79% liked the foaming resistance
I had noisy lifters, so I added engine-oil-fluid-additives to the oil and ran it for about 30 minutes. Then, I dumped the oil and have since driven about 1000 miles without any noise. The oil seems cleaner now.
76% highlighted the viscosity rating, but 24% found it confusing
Even after changing gaskets, diaphragms, and other materials, there are still some leaks due to the viscosity of synthetic oils.
79% were satisfied with the cold start performance
I had noisy lifters, so I added engine-oil-fluid-additives to the oil and ran it for about 30 minutes. After dumping the oil, I have been surprised that I have driven about 1000 miles and the oil seems cleaner and I havent had noisy lifters.
I have been using the product at every oil change since new and my engine has over 700 hours of harsh usage and still runs strong with no exhaust smoking or oil consumption.
I have been using this product for over 30 years and find it especially important in high performance engines of Classic Cars.
76% highlighted the oil filter compatibility, but 24% found it limited
I have used this product in my mower and off-road dirt bikes, but it warns against using it in newer passenger vehicles due to possible damage to the catalytic converter.
74% liked its compatibility with engines
I found that the additive significantly reduced the noise.
I have been using the product in my Exmark with a Kawasaki air-cooled engine since new and it has over 700 hours of harsh usage and is still running strong.
Adding Rislone helps coat and adhere to the mechanical parts of my engine. It's a positive feedback for the compatibility feature of engine-oil-fluid-additives.
