Frequently Asked Questions...

Do I have to flush my oil after using Rislone Engine Treatment Concentrate?

No, Rislone Engine Treatment Concentrate is formulated to be left safely in the crankcase for the life of the oil change for maximum performance. It is not an engine flush and does not require draining.

How does Rislone Engine Treatment work?

Rislone Engine Treatment gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages. These deposits form within engines and can alter tolerances, stick valves and rings, cause noisy valves and lifters, and plug oil screens and passages. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum.

How long does it take to start working?

Rislone Engine Treatment Concentrate starts working the minute you install and start driving the vehicle to help remove harmful gum, sludge, and deposits from your engine.

  • Have you ever thought about cleaning your engine? We don’t mean the outside. We mean cleaning the inside, where years of oil, fuel and coolant use has created a buildup of sludge and debris. Cleaning all that out can allow your engine to run smoother, develop more power and eliminate excess wear. The result is a more responsive engine that gives better fuel economy and will last longer.

Product Description

Rislone Engine Treatment is high quality penetrating lubrication oil, combined with protective engine additives and special cleaning agents. Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range. Sludge and other harmful deposits within engines can alter tolerances, stick rings, cause noisy valves & lifters, and plug oil passages and screens. The unique Rislone formula is designed to penetrate into bearing surfaces, piston rings and ring grooves, where sludge and varnish is likely to form. These deposits are gradually removed and held in suspension until they are trapped in the filter or removed with the next oil change. Regular use of Rislone Engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum. A cleaner engine is a better lubricated engine with less friction & wear.

    I normally don't write reviews but this time one is deserved. Here is my story.For over the last 2 years my 2015 Jeep Grand Cherokee has had a P0304 code. Which means misfire on cylinder number #4. Sometimes the check engine light would come on then go off on its own and sometimes the check engine light would stay on and I would turn it off with my scan tool. I was not able to clear the engine P0304 DTC code because it was a logged into the PCM as a (permanent code). I was just able to turn the check engine light off with my scan tool I moved the spark plug from Cyl #4 to Cyl #2 and moved the coil pack From Cyl. #4 to Cyl. #6 and installed a new fuel injector on Cyl. #4. None of the above made any difference. I took it to the garage 3 or 4 times and had the throttle body cleaned and mass airflow sensor cleaned etc. the last time I had it in the shop they told me I needed to replace one of the heads on my 3.6 L for $3800.00. They said I had a valve sticking or a failed lifter or rocker arm problem they didn't know for sure until they tore it apart. I mean the engine was running smooth as a kitten making no noises at all. I was a little leery of this. Well I don't know about you all but $3800.00 is a lot of money. So before going that route I purchased a 16oz bottle of Rislone High Mileage Engine Treatment. along with (5) bottles of Rislone 4700 Hy-Per Fuel System Cleaner. I ran a 1000 miles with the above and guess what? It cleaned out what ever it was that was the problem and removed the P0304 (permanent code) which was now listed as just a P0304 and I was able to clear that with my scan tool. So now life is good with no more P0304 code and a cure with only $70.00 worth of Rislone products. I feel like a rich man with an extra $3730.00 in his pocket! I purchased a case of Rislone Engine Treatment and have been replacing one quart of oil every oil change just for safe keeping. So this stuff is a 10 in my book and I hope I helped some of you out with my review. Photo shows the all clear!Happy CamperKevin Constantine
