Review on Rislone Engine Treatment, Pack Of 1 For Enhanced Performance - 100QR by Jason Page

We were headed home from a vacation in the Rockies, pulling a 25 foot long RV with our 2008 Yukon Denali with the 6.2 liter engine. The oil pressure had been pretty low for a few days and the engine would overheat when climbing a steep grade. Finally, in western Missouri, the oil pressure warning light came on and the engine was pretty hot. I called my mechanic back home who had done some work on the Yukon, and he recommended I buy Rislone Engine Treatment, find someone to change the oil and add the Rislone. We found an oil change place and added the Rislone to replace 1 quart of oil. From then on, the oil pressure stayed at a normal level, and the engine never overheated. This was about 6 months ago, and the thing runs like a top. From now on, I will continue to use Rislone Engine Treatment at every oil change in every vehicle I own.
