A person can't think of a motorcycle engine as if it's a car engine. Although they have things in common, most motorcycles use a wet clutch.

If you dump this crap into your oil and it causes the clutch to slip, you will be in trouble. Parts will cost 300, or so, and many people would have to have the dealer do the repair, so add another 200 to that.

Mentioning California going down the toilet made me laugh. My dad made the same comment , to my grandfather, in 1972 as we drove through the Haight-ashbury area. The only thing that has changed is the 30,000 dollar house is now worth 3 million.

 

Just what we need. People introducing politics to our motorcycle forum.

 

Bob, the recommendations will work perfectly well for you, or anyone else who doesn't care to study the subject as to why. That's what manuals are for. A guick guide that won't get anyone in too deep, or exceed their knowledge base.

 

The remetallizing compound CSL was originally developed at NASA to lube Space Shuttle gyroscopes. It is these tiny particles that fill and seal micro-leaks in the engine's cylinder walls....Why Does Engine Restorer Work?
Engine restorers work by filling in worn areas within the engine cylinders, improving compression, and enhancing overall engine performance. They contain a blend of 30W SAE mineral oil, detergents, and anti-corrosion agents that work to carry restorative particles into the engine. These particles, such as CSL micro-particles, act like an engine additive with 30W SAE mineral oil, including anti-corrosion agents and detergents. They create the engine's reparative operation by alleviating friction and rebuilding metal surfaces inside the engine. Engine restorers are particularly effective for engines experiencing compression loss or minor smoke issues, as they may assist in sealing and reviving the engine's performance without the need for immediate mechanical overhauls.

My 2011 Ford F350 service truck was sold with 305,000. The only service item it had was wear items. It was always overloaded by about 1000 lbs. This had the 6.2 gas engine

I did have the spark plugs changed at 225,000 just because the fleet manager was an idiot. He demanded the n"plugs and wires" be changed so I had rhe mechanic add in 125.00 for plug wires that didn't exist. He would have loved engine restore. Modern vehicles use stick coils. Plug wires disappeared years ago.

These were tools to do a job so maintenance was sketchy. The leasing company had a deal with jiffy lube and we changed the oil when we could.

Bob, I'm surprised that you didn't read/learn something about octane booster. It sounded like you might be interested enough to where you might take ten minutes to educate yourself, but I can see that I was wrong.

I'll say that it doesn't work.

I've worked with companies who use fleet trucks and what they do is maintain their vehicles instead of neglecting them. A product, like this, isn't even mentioned in an emergency plan.

If you suggested it's use, you would be fired for incompetence as a fleet manager.

 

Kept two of my Honda Accords with over 200,000 miles running strong. Also keeps my 1998 Ford Escort running strong with 177,000 miles on it. But, its a free country, so don't use it if you don't want to. PS RC, please put some octane booster in your bike, and report back to us! lol

 

Bob, you are the one who brought it up and told us how wonderful it was. That makes it your job to show some kind of proof. This isn't hard to do on products that have value.

 

Restore results are in !!

 

Imagine if someone really found a liquid that would fill wear marks in metal.

I don't think you could afford to sell it to consumers. Industrial customers would pay a lot more for the product. I believe you could charge 2000-3000 , per bottle, and still be sold out. Even if it only worked for two weeks, I can think of a few occasions where my boss would have yelled at me for not buying several cases of the magic product.

BTW, I don’t t know if the results of this article are true either 🤭 But I found an awful lot of articles on this subject.

 

Part of the problem with the engine restore products is mentioned in the description. It's not permanent. Liquid doesn't turn into metal...well, except for 3d printing. If you have a scuffed up bore, or bad rings, that has to be repaired for any long term success.

 

No, just add it with every oil change. Thats helps seal the pistons and rings against the cylinder walls. The results have been proven.

 

The summary part sort of brings you back to the "is it really worth it"

But, it is up to the user, if it helps you, then go for it.

Fuel wise, a friend of mine used a Liqui Moly fuel system conditioner on his 4 cyl car, which he thought was running quite well after a suggestion from a spannerman, he was shocked to be honest.
It made a big chnage to the car. He and i both live up top of soome super steep roads, and he was able to hold 1 gear higher going up, and, he fuel economy improved by about 5 - 10 % depending on driving.

He monitored that, and felt it start to drifat back after about 9 months, but this time he used an injector cleaner and that brought it back again, he had used that one before with no results.
Screwed if i know what the L.M. stuff did, but he was happy

 

In a decent, modern motor you would rebuild it if it ever needed the snake oil product you are talking about. Its performance would have fallen off so much that it wouldn't be useable.

Now that you brought it up, find one example where this product did what it was advertised as doing on a power sports grade motor and I'll read If about it. If you had done regular oil changes on the Honda car, it wouldn't have needed this in the first place.

Forums & Community Insights

• BobIsTheOilGuy Forums
  Users report improvements:
  

  “Restore boosted the compression… we got about a 15# boost in compression and it evened out all 6 cyl so it runs a lot smoother.”Bob Is The Oil Guy
  Another said compression rose from around 131–145 psi to 194–206 psi on a shop engine.Bob Is The Oil Guy

• Individual Case – Volvo
  A user recalled raising compression by ~20 psi in the worst cylinder and ~7–8 psi in another; noted better responsiveness and throttle control.Bob Is The Oil Guy
• Reddit / r/cars
  Mixed perspectives:
  

  “The Engine Restore vehicle was the only one which raised compression and kept it there after the testing… the Engine Restore only raised it 3–5 psi … but the fact that IT WORKED was enough…”Reddit
  Some caution that it may harm modern VVT engines by clogging critical passages.Reddit

• Reddit / r/prius
  A DIY endorsement:
  

  “Project Farm on YouTube tested Restore and it improved compression significantly on all four cylinders of his old tractor.”Reddit
  But others had check-engine light issues when used in modern VVT-equipped vehicles.Reddit

• Skeptical Reddit Voices
  Some users dismissed it as “snake oil” and insisted that low compression requires mechanical repairs—not miracle additives.Reddit+1

Summary at a Glance

Aspect	Observations
Compression Improvement	Users report increases ranging from ~3 psi to over 60 psi in extreme cases.
Engine Sound & Performance	Often noted smoother idling, reduced rattles, better throttle response, and quieter running.
Fuel & Oil Usage Benefits	Multiple reports of reduced oil consumption and modest gains in fuel economy.
Duration of Effect	Some say benefits lasted thousands of miles; others caution it may be temporary.
Risks or Limitations	Potential issues in modern VVT systems; some say it doesn't "fix" mechanical wear.
Mechanic & Community Views	Mixed—some hail it as a useful band‑aid, others warn it may be wasted money.

Takeaway
Yes, compression restoration products can deliver noticeable short‑term improvements, particularly in older, worn engines. Many users have seen measurable increases in compression and smoother performance. However:

• These are not permanent fixes—an engine with worn rings, seals, or valves still requires mechanical repair eventually.
• Modern engines with VVT systems might suffer adverse effects due to additive residue clogging oil passages.
• Results vary—some users report robust improvements, others minimal or no change.

If you're seeking a temporary reprieve or want a diagnostic boost before a rebuild—and especially if your engine is dated or burned oil—running a compression restorer could be a worthwhile, low-cost experiment. Just be mindful:

• Use it as instructed.
• Run compression tests before and after.
• Monitor performance and be cautious in engines with advanced variable timing.

 

Maybe in a lawnmower, but not a motorcycle engine or anything I cared about. If a person changes yheir oil they are way ahead of what this stuff could ever do.

 

Testing on 4 cyl to V8 motors has seen compression go up by 20%. I've used it on my 496 Cuda, which has at least 50,000 miles on a 20 year old engine, and two years ago I checked peak cylinder pressure, and they were all around 190 psi. And I use only 3 rings per piston and use lower tension rings.

 

Yeah, i dont know why editing is so restricted here.... cant even delete a post.
Its the same site owners as other pages i have been on, one i can, and the other i cant.

As far as the engine stuff, i wonder if it works with modern nikasil and other plate bores ?
Older stuff was just raw metal

 

I don't know, but there is always gonna be wear between piston rings and cylinder walls over time. I've seen my Honda Accord, with 200,000 miles on it, come alive when I started using this stuff.
