Here is how I found out about it (bear with me):
When my dad was seriously ill I had to travel from here to KY to help my sisters out with dad. The car rental group I worked with did not have a vehicle on such a short notice.
So I had to drive a distance of 520 miles one way, in my 2003 Nissan PathFinder, V6 engine. First over 30 mile trip with this vehicle in 7 years. Vehicle has 146,000 miles on it.
After going through the Ozark hills in Missouri, and about 70 miles from Dad's house, I started loosing power on hill climbs. It had never done this before. It would downshift to 3rd or second gear and rev up to 4,000 rpm on climbs.
I pulled off of I-55 and proceeded through the two-lane backroads and nursed it to dad's house.
The next day I took it to my Dad's favorite mechanic who had a big shop in town. He had just recently hired a Nissan mechanic away from a Nissan stealership. The Nissan mechanic diagnosed the problem as a malfunctioning VVT valve, most likely carboned up and sticking.
The shop was two weeks behind (a roof had collapsed in one section of the shop from heavy snow a week before).
The owner and head mechanic suggested I go to the AZ store and use the Rislone product in the meantime. I thought to myself, "Geez, another shade tree goodoleboy mechanic trying to blow a Yankee off" because he was overbooked.
Well, here I was 520 miles from home with a sick PathFinder, so what the heck.
I purchased the Rislone product and put a half quart into the engine. Within 10 miles the engine smoothed out and power was restored. No more downshifts.
Before I left the area I went and told the owner thanks and the engine had returned to normal. He said he has seen this many times where these Nissan engines have not been run hot enough to sweep the carbon from the VVT control valves, especially in these year engines where they had an early VVT control system. He said these valves will stick early on if oil changes are NOT done using the severe service schedule. Well, I have always used the severe service schedule for all my vehicles, especially since I have my own lubricants.
So when I got back home I had it analyzed.
As you know I am not a fan of aftermarket additives and do not believe they are needed, except for specific circumstances.
In this case, the Rislone product did the job.
