Hello, everyone We are Chingsui Agricultural Machinery We're going to do a test today ok, first of all, let me introduce that this can of oil is the original company oil of STIHL The recommended ratio of this can of oil is fifty to one The recommended
ok Some people will want to know what fifty to one is when they hear this. I'll make a popular science fifty to one with you at this ratio Fifty to one means that 50 ml of gasoline is better than 1 ml of engine oil is This milliliter if you don't quite understand it That's what we often mean by 1 cc If it is converted into one liter of gasoline, A liter of petrol is 1000 milliliters That's twenty cc of oil 20 cc oil is good This is STIHL's One of their suggestions in the original factory abroad I suggest you use this can of oil Then do this proportion to make harmony For us, the climate in Taiwan is relatively hot In subtropical areas, we all recommend that guests reconcile with a ratio of 40 to one Forty to one is 40 milliliters of gasoline If you add 1 ml of oil and convert it into liters, A liter of petrol is twenty-five cc of oil Give everyone a concept A liter of petrol with twenty-five cc of oil is good A liter This kind of reconciliation will protect your machine more. Don't be afraid to say that you use fifty to one Sometimes an error in this ratio may cause your machine to shrink In this way Today I will use this can of STIHL's oil Then I will do a test with you If we use the standard 40-to-1 way to reconcile What will the chainsaw do If I add more, If I use the ratio of twenty-five to one to reconcile, What will happen to the machine Let me tell you about it first Twenty-five to one Twenty-five to one It's 25 milliliters of petrol and 1 milliliter of oil Converted into liters That is, one liter of gasoline requires 40 ml of engine oil The amount added is twice this fifty to one, which is equal to twice the oil In this way, today I want to do a test with you If the oil addition exceeds our original factory, it is the recommended value What kind of performance will the machine have We will look at four kinds of data today The condition of the first Mars plug The status of the Mars plug Second, I'll look at the speed of the engine The speed of the engine The third temperature of our cylinder Cylinder temperature The fourth is the exhaust pipe degree Exhaust pipe temperature Today, these four are the main ones to make a comparison with you What I use to compare today is mainly the ratio of forty to one and the ratio of twenty-five to one Today's proposed reconciliation ratio is in accordance with STIHL, the original company, to do reconciliation If you are buying gas from a gas station or the package does not write any proportion suggestions Please give priority to twenty-five to one Please do the reconciliation in a twenty-five-to-one way Different oils You just follow the original factory's way to do it and reconcile it in order to reduce our error We use a measuring cup to mix the left side If you come to the group on the left, it will be our forty to one Let me show you a 40-to-1 blend. One liter of gasoline needs 25 ml of engine oil Behind us is a liter of gasoline Then let's show you this 25 ml 25 ml Words on the right (slip of the tongue) The ratio of twenty-five to one is that it is better to add 40 ml of engine oil to 1 liter of gasoline engine
Same There is a liter of gasoline in the back Then come forty 40 ml is good Wait a minute Let's measure the ratio of forty to one first And then after we re-washed the oil circuit, Let's test the ratio of twenty-five to one Then the model tested this time is Komatsu's G3800 G3800 This is a chain saw for testing I'll drain all its original oil later Then empty the oil drum as much as possible Then we'll wait Let's test the forty-to-one harmonic one first Well, wait a minute. The test method I'll get our new oil in first That is, the first thing we want to test is the ratio of 40 to 1 mixed oil Then I will idle for 5 minutes Idle for 5 minutes Then let it go full throttle for another 30 seconds Let's measure its cylinder temperature again Then there is the temperature of its exhaust pipe and the state of Mars plug pipe
Let's pour the oil now Good
What we're pouring in now is a 40-to-1 blend of oil Then let's start it now Then let it idle for 5 minutes Good Now we use a 40-to-1 mixed oil We've been idling for five minutes now Let's first test its idle speed Probably at 3150rpm 3150rpm. Let's test its cylinder temperature now. Okay now.
The cylinder temperature is sixty-five degrees The exhaust pipe temperature is 70 degrees Seventy degrees is good So we're ready for 30 seconds, full speed, full throttle Then 30 seconds. Come on Let's start Flameout Good
Let's look at the temperature right now The cylinder temperature is about 135 About one hundred and thirty-five It's about two hundred and three (exhaust pipe temperature) 230 degrees (exhaust pipe temperature) Good
I'm going to tear down this spark plug and show it to everyone This is a 40-to-1 mixed oil Then the new Mars plug tested it I'll zoom in on this ok It's a little anti-white Carbon deposition is not very serious There is basically no carbon deposit This is the performance of Mars plug made with 40 to 1 oil Wait a minute. I'll put a new Mars in the same 25-to-1 oil Forty to one oil is poured out But let's wait and change the oil for twenty-five to one Then let's make sure there is no oil in it at all Okay. Besides, we need to install a brand-new Mars plug. Brand-new Mars plug Good
What we are adding now is a blended oil with a ratio of twenty-five to one Let's start it as we do now for five minutes OK, now we use a 25-to-1 mixed oil And now it has been idling for 5 minutes Then let's look at its speed first About three thousand three hundred turns Test its temperature seventy-seven Seventy-seven Seventy-seven Then let's time it now Time 30 seconds Good Prepare to begin Good
Let's see its temperature right away 245 good just up to 245 good ok Good
Then this one uses a 25-to-1 mixed oil Then the Mars plug used is in good condition Let's show you ok That carbon deposition also looks good at present Let me tell you about some data we just measured The first time we tested it, we used forty to one It is this mixed oil with less engine oil It's three thousand one hundred and fifty revolutions when it's idling 3,150 revolutions per minute Twelve thousand turns at full speed Twenty-five to one the second time It is the one with more oil The more mixed oil is better When idling, it is 3,300 revolutions At high speed, it is 12,550 turns It is higher when the speed is high It's about 500 turns more So I can show you a comparison table of temperature This side is the temperature of our idle speed On the right is the temperature when we are at high speed Then when these two cylinders and the exhaust pipe, This is a 40-to-1 mixed oil The following two words are twenty-five to one mixed oil That's twenty-five to one oil More oil Then forty to one oil is less Good Let's compare it When we use a 40-to-1 mixture of oil, You see, its cylinder is only sixty-five degrees at idle speed The exhaust pipe is seventy degrees At high speed, the cylinder temperature reaches 140 degrees The exhaust pipe temperature is two hundred three Let's take a look at the following part That is, when there is more oil, the cylinder is a little higher than before Come to seventy degrees The temperature of this exhaust pipe is seventy-seven degrees At high speed, the cylinder is 185 degrees Then the exhaust pipe is 247 degrees at high speed ok
On average, if you look at it like this, you can see that there is more oil than 25 to 1 Its average
temperature is higher than forty to one It has to come high ok, this is actually very easy to understand Why Because if you have a lot of oil, When you burst into flames, It takes longer to flash Speaking vernacular means that it takes more time to burn out the same (mixed) oil The longer you burn, the more time you burn The more heat it accumulates Then the temperature will be a little higher It's a little higher Good two Mars plugs On the left is a 40-to-1 mixture of oil On the right is 25 to 1 mixed oil That is, there will be more oil on the right side In fact, because we may not run at high speed for long enough, not long enough So the two seem to be in a good condition Not much difference If you add too much oil, What kind of shortcomings will there be The first The power can't come out When you saw something, Why don't you think the horsepower can't come out Feeling without force In the second case, its carbon deposition is faster Carbon deposition is faster Third, it has more smoke There will be a lot more smoke than you usually come The fourth, of course, is that the temperature of your engine will be a little higher than usual It will be higher That's my personal opinion I don't know what you think after reading these data You are welcome to leave a message below to let me know If you like our actual measurement here, Welcome to click like to subscribe and share Then I'll see you next time.
