User questions & answers

Question:	How often should you use this
Answer:	Should not be used at all. Caused my engine to seize.
Question:	Can it be used with synthetic oil
Answer:	Should not be used at all. Caused my engine to seize.
Question:	How far can you drive it with the flush? Is 300 miles too many
Answer:	Dear Customer, Thank you for your question. We value your business. It is recommended to idle the engine for 10-15 minutes or to get better results you may drive for about 12mi. If your engine has severe contamination - you could try going for 90-120mi with it, but no more. This is a very powerful solution which will clean everything thoroughly. Best Regards, XADO TECH
Question:	My engine seized after adding this to my truck engine. Drove 10 miles. Has this happened to anyone else
Answer:	I have not tried it yet. It all depends on the age of the engine, prior problem before adding this and also what made you use this? It also depends on the type, make and model of the car. I wanted to do plenty of research before using it in my 2004 jeep grand Cherokee 4.7l engine. I just did sea foam treatment and did the oil change .. after 100 miles. I am going to do another oil change with this stuff. I heard if the engine is badly clogged up and dirty from the inside then you want to do it slowly.. plenty of times with little portions instead of using it all at once because this stuff is powerful. Maybe some of the dirty elements got stuck to the running system.. and it may need mechanical cleaning.

User questions & answers

Question:	Does this work for synthetic oil
Answer:	The instructions for use are pretty clear. It is to be added to the engine and allowed to idle for only 5 minutes before the oil change. You should change the oil and filter immediately after using this product as directed. There may be a trace amount in the galleys etc but for all practical intents and purposes it drains out with the oil. If you are not planning to drain all the oil and change the filter, do not use this product. Certainly don't add it to engine oil and drive around. I have used this product as directed the past 3 oil changes on my vehicle with 250k miles on it and no surprises. This is actually a detergent, not a solvent as most "flush" products are. On a side note, I spilled some of the used oil on a recent change, and it cleaned up well without staining the concrete.
Question:	Will this work to take care of any oil pump issues that I may have or oil pressure
Answer:	warm your engine up for about 15 minutes and then pore in the Lubegard. With the Lubegard now mixed in with the oil, run engine at an idle for (10) minutes. No longer or it will damage the engine. Do not drive the car with the Lubegard in it!!! Shut of engine and drain the oil. Install new filter and oil and your all done. Hope this helps you.
Question:	This flush works for all type of engines ? I mean gasoline, diesel and turbo eqiped engines
Answer:	Hello - This most definitely is safe to use in that engine. Please let us know if you have any other questions or need additional help. You can send us a message direct at [email protected], or give us a call at (800) 333-5823. Thanks & Happy Motoring!
Question:	Can you use this with synthetic oil
Answer:	I have never used gumout. Sorry.

Product description

TRIAX Max Oil Booster S7 is one of the most advanced engine oil supplements and engine treatments ever made with an extremely wide range of benefits, in virtually every aspect of engine and oil functionality. It is basically an engine treatment on steroids, as well as sludge and carbon deposit cleaner, anti-wear friction modifier, oil viscosity stabilizer, TBN booster, acid neutralizer, and corrosion preventer - ALL IN ONE product.



TRIAX Max Oil Booster S7 is the best engine protector and oil booster you can buy, from any brand anywhere in the world. It contains a patented, proprietary formulation of ultra-high performance additives and inhibitors to bring you the most advanced engine protection possible.



TRIAX Max Oil Boost S7 is a complete solution to oil treatment needs such as smoking vehicles, engine noise, oil consumption. While it does improve high wear symptoms, this product does not FIX existing engine problems resulting from years of abuse and use of sub-standard motor oils, it is designed to protect the engine and to dramatically enhance motor oil performance and prevent problems from occurring in the first place.



If you are using this product for the first time to clean your engine, we recommend a 5/1 treat rate about 1000-2000 miles BEFORE you change your old oil. When oil change comes up, it will remove all the sludge and carbon deposits with the used motor oil, preventing contamination of the new oil.

• Friction modifiers with Organo-Molybdenum and Nano-Borates and High Phosphate Retention ZDDP. Provides massive anti-wear boost to all engine oils. Exceptional protection for turbo-charger bearings - prevents the oil from frying on the bearings and creating deposits
• Increases oil TBN by 3 to 6 points depending on treat rate, preventing acid corrosion. Ideal for heavy duty applications.
• Significantly improves viscosity stability, oxidation stability and oil's ability to handle high thermal loads, contamination and friction.
• Replenishes virtually all motor oil additives, extending its life by up to 200%.

• For repeated use, change oil every 3,000 miles on most passenger vehicles by substituting 1 quart of motor oil with Dura Lube Sludge Away. Continue using until sludge appears to be reducing. Check oil pan to review sludge consistency on discarded oil
• For more severe sludge build up, change the oil and add Sludge Away engine product every 1,000 miles
• Repeat application as needed until performance and oil color returns to normal; oil color should be amber to a dark brown, not black
• Sludge Away engine product works with all types of motor oils including high mileage and synthetics

Frequently Asked Questions:

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.

How does Rislone Engine Treatment Concentrate work?

Rislone Engine Treatment Concentrate 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 much Rislone Engine Treatment Concentrate do I install?

One bottle of 4102 Rislone Engine Treatment Concentrate 16.9 oz. is designed to treat 4 to 6 quarts of oil. For larger systems, stationary engines and diesel trucks, use 1 bottle for every 5 quarts of oil capacity. For severely dirty engines, use 2 bottles (double dosage) of Rislone Engine Treatment Concentrate and change the oil and filter after 100 miles of driving.

User questions & answers

Question:	will this work in a car that has 9 yr old gas in it? it has 1/2 a tank in it about 9 to 10 gallons? will this cleaner restore the inside of the tank
Answer:	It's on the package. Vet recommended msm and glucosamine together to get proper benefit.
Question:	Break down Maple syrup
Answer:	I had to call and find out because I was concern if it's a product of China. According to the company, this product is manufactured by them (AHC Products. Inc. · 301 W. Broadway, Winchester, Kentucky) and monitored by FDA, but their supplier is in China. I originally purchased a container of one-pound MSM from our vet, whom I've known over 20 years, and also given it to my previous dog. My current dog has been on it for nearly 3 years without any problem. He is healthy and vigorously active. But I intend to ask the vet of her experience/opinion on the next visit.
Question:	Can this be used for heating oil tanks
Answer:	I'm not sure what you mean by concentration....but there are no fillers. The product is pure MSM granules. Use 1/8 tsp per 30 lbs of body weight. Use 1/2 ounce per 1000 lbs of body weight. It can be used for animals, including dogs, but I also use this MSM myself. I have been using this for almost 2 years now...this brand. It has the exact same benefits as the very expensive MSM for humans, which I used to use. Hair, skin, joints...amazing...plus other health benefits that I can't name here...but I won't go a day without it and neither will my animals.
Question:	Will this product break down varnish in bottom of tank that has been sitting for several years

User questions & answers

Question:	It's good to put it before fill up or after
Answer:	Dump it in at the pump before filling up. That way the fuel rushing into the tank will mix it in rather than dumping it in after filling. Eventually it'll attain uniform mixture but dump then pump will mix it right away.
Question:	I can run Sea Foam in the crankcase along with my oil at all times or just as a cleaner prior to changing the oil
Answer:	It says right on the bottle, you can add it in the crankcase 100-300 miles right BEFORE oil change.
Question:	how does it do in motor oil
Answer:	I just used Sea Foam in my oil for the first time. I have a 50 year old car with its original, never-rebuilt motor. The lifters have been tapping for awhile so I thought it was worth a try. I added Sea Foam to the crankcase oil according to the directions (1.5 oz. per quart of oil). I let the motor run for about 15 minutes. The lifter noise went away almost immediately. Afterwards, I changed the oil as normal. When I drained the old oil, it was noticeably thinner due to the presence of the Sea Foam. I added new oil and filter, and the engine runs like a top now. No more noise. This stuff is great.
Question:	This item (Sea Foam Motor Tune-Up) oil additives? Or fuel additives
Answer:	seafoam is mainly a fuel system cleaner and it does work well. as for your oil, it acts as a cleaner also, targeting sticky valves, dirty port holes , dirty lifter issues etc
