Takes a few heat cycles for it to have a full effect. At least in my experience of restore

I've always wondered if that stuff was any good. Thanks for the test!

Hello Hank, Back 20+ years ago the Engine Restorer people wrote on the can, "Use at least 400 miles for full treatment. If you use it about 12 running hours if it's going to work, it will by then. Most lawn mowers have a throttle governor that keeps revs low. If you could keep revs up to 4,000 rpm it might work in 8 hours.

I had a honda lawnmower I used in my lawn business. It ran well but it would smoke for a while. I put a small amount of engine restore in it. It stopped smoking and I gave it to a friend and a year later still going well he said.

Good review. However, I would have used it with fresh oil. I use it on my 2001 S-10 4.3L, with 165,000 miles. I don't have compression issues, but it seems to make a difference in power, smoothness, and gas mileage when using it.

I’ve been using this stuff in my car for ten years and so far I’ve had no check engine lights so who knows if it’s kept my engine running well? Perhaps? Been using the fuel additive under the same brand also and noticed good fuel economy

Did you check it at the same temperature before and after?

Thanks for checking the Restore product for us shade tree small engine mechanics (I am just a home gamer). I am interested to know what the compression is for a new Tecumseh engine is. I suppose I could go look for my compression gauge buried somewhere in my toolbox and test my own equipment as well.

I've heard this blackens and can score bearings. Can you run it longer and tear down down bearings to see what effect the lead-copper additives have?

It works, it also quiets down the knocking sound of a worn rod. I know it because l bought an used push mower over a year ago and it had very dirt oil ( it was actually the restore product, l didn't know anything about this product at that time) change the oil, start the mower and then a knocking sound.. I realized that "engine restorer" was what made the trick hiding that knocking sound from the worn connecting rod ( l guess that engine was run with very to no oil) and the guy whom l bought it from just did a quick fix to get some money. Anyway l didn't want to risk anything so l dumped that mower but it worked very well with that product in it, although exhaust gases smells weird.

I have had that same motor for over 20 years. Thing is a beast!

And yeah I run that stuff in all my vehicles and it takes a few cycles to get fu'll affect but my throttle response and all around power is substantially better after running it

I have a riding mower and everytime I cut the grass, I wonder if the mower will last long enough to finish the lawn ! I will be purchasing this before my next cut !!

Project Farm had good results with this in similar testing.

Crank your engine with a electric drill. Like project farm. That's the only way you'll get a near accurate pressure

Eager 1 mower the #1 junk ever made, paid $250 for that crap 42 years ago , always had trouble to mow my lawn

hi, can you please update if this stuff helped long term?

I've added compression before by sanding down the cylinder head flat and running without a head gasket. Same sort of situation - mower that was on its last legs unless I replaced piston and rings.

I am here for wizard guidance! Question for you, as to what product and how much you think I should use. I have a 1995 Subaru 1.8L 4-CYL boxer Impreza, 177,000 miles. I have 76 and 78 PSI dry compression in #2 and 4 of one head (driver side). This started a few days ago, we noticed while on a highway trip the power was weak and I can hear it missing as the RPMs drop from driving to idle. I don't have overheating, excessive oil consumption (drippy seals, I add a quart about every 900 miles), smoking, or fluids cross contamination. I'm waiting to have a leak down and another dry/wet compression test at a different shop. The first shop only did dry compression and wasn't too bright or helpful. If I end up having a head gasket leak between those two cylinders, what products would I possibly try to mend it? It must not be too bad of a leak, whatever it is, for the compression to build to 78psi dry. The other two good cylinders are 130ish psi. If it ends up being a valve leak, what products and strength could I try to get them clean? After cleaning, I will have valve clearances checked, as it's probably never been done. Thanks!

Would like to try this on a riding lawn mower. How much should I put in? Thanks

I've heard nothing but positive feedback on this stuff

well, don´t expect to see a HUGE bump in compression, specially in an engine with tons of miles in it, also it takes several hours to make effect, until the rings and cylinder get a uniform coating of the blue stuff there´s no way to see any difference... i used it in my old jeep 4.0 to help with the blow-by and i´m happy with the results, blow by was greatly reduced, compression and therefore power also went up a little and as a nice side effect, the engine runs a little cooler, i guess the restore gives the rings a soft bed to ride on, reducing friction more than just with oil anyway, i think the product delivers what it promises, just don´t expect it to resurrect a dead engine...

Can’t wait until you try and experiment with MT 10 (the best friction reducer I have ever used)

MegaFlaxman I hope I can get a response on this question. I have a 2008 Honda clone 6.5 horizontal shaft. It was in the original box till just recently when I aquired it. I filled with oil and gas and wouldn’t start. I checked the compression and it’s 28 psi. Checked the rockers and they’re moving like they should. I removed the rockers and physically moved the valves up and down, both seem to be seating properly. Filled cylinder with oil and tried again, still 28 psi. What’s my next move, remove the head and check the valves?

I poured a can of that in my Jeep Grand Cherokee last oil change, the engine runs very nice now, noticeable increase in power.

I swear engine restore is magic in a can

Is that a vintage analog/digital seiko watch you own?

Does it also reduce a little bit of knocking noises?

Tecumseh engine?

In the olden days we actually used lead shot stick in spark plug hole it was filled the gaps between the rings in the cylinders

What they don't emphasize is that the product also does a remarkable job of cleaning out the sludge in an engine. Religious about the maintenance on a car that's been in the family since new, this week the 5,000 mile oil that was changed had a can of Engine Restore added to it. The appearance of the black, gooey oil that drained out was shocking. The filter element (paper only on Mercedes) was solid black. Usually the oil is a medium brown color. Replaced with a synthetic that included another can of Engine Restore, it will be interesting to see what the next oil change looks like. The car is a 245,000 mile Mercedes 4cyl.

not snake oil, best stuff I've ever used. makes an old engine run like new

Hey kind of off topic, but I was just wondering what you think about a toro mower with a blade stop clutch, I was told there not as reliable because they have a belt that drives the blade. I was just wondering what you think about that since your really good at repairing mowers, also is a mower with a blade clutch just as powerful as one without? Thanks in advance

engine restore works great, but in a pinch try 25 to 50% ATF for a short time and then change it. I've even used ATF down the spark plug and then slowly pull it over for a few times over a few days and then clean as much out as you can. try not to compression lock, the cylinder or bad things happen but that loosens up carbon

Great job Thank you

What would you sell a mower like that with a bag in decent .I have a chance to get one for$ 20 .It needs a carb kit or China carb,filter.So that's 30 in parts or so looking to flip it.

I used Restore in 1976 caddy 500 cubic Inch engine, had about 130,000 miles after about two weeks I noticed smoother running and better gas mileage ok it was a Caddy so gas mileage wasn't good just better. I used it in lots of older engines, never thought about putting it in a lawn mower engine though.

Check the oil,,,it's about halfway, that's good enough for me.

To me it seems it's an exhaust valve issue, just by the sound. I would be curious to see the compression if the exhaust port was plugged.

👍

interesting

It seemed like you used way too much. I would follow the directions and mix it with the oil. That said, your lawnmower could be suffering from something else. Our lawnmower saw about a 20 psi bump, and a significant reduction in oil consumption. My 1993 Honda Civic saw a 30 psi bump and a huge reduction in oil consumption until I finally did an overhaul. Got me another year down the road. Those who are saying it is thicker are wrong as well. It is a 30 weight. The metal in the additive is what seals it better. When I changed my rings, I found all these gritty particles, the soft metals that hardened when cold but seal the cylinders when hot. Stuff works great

yes i did enjoy this vide

I would try running a full bottle of that stuff

ADD TO GASOLINE ALSO, WORKS EVEN BETTER. USA PATENT ADDATIVE SINCE 84.

I think that engine is worming out.

The real question, how long does it last?

it will never restore metal that is worn and that is expelled in used oil. it can save the situation but it is a patch, not a reliable solution.

Couldn’t spare half a quart of fresh oil??

Restore works, we have used it for 25+ years.

Well If It doesn't work in a mower that don't have oil filter, imagine in a car engine that has efficient oil filter ... I thought It worked, but now I'm in sérious doubt.

4 oz for small engine means 4 cyl engine

Sounds like a head gasket leaking.

There's your problem... it says Craftsman Sears stopped making good products long ago

Seem they smoke any was

Tecumseh engines are prone for failure. Tecumseh engines are the worst small engine ever made.

Just put a can in my car with 167k miles. Not expecting miracles. Read a review of a douche putting it in a brand new Civic(lol) then complaining because he blew his motor. It's Restore not "Add 15+ HP" in a can🙄😂
