I hear of others having oil temps of 240+ even up to 300 degrees. My temps never really went over 212 degrees " and that's running hard " I was told that even 240 + was normal . my temps recently have been between 212 - 270 or so , maybe higher. I found that my oil pump is not working !. After about 20 mins of idling , my scoot had an oil temp of around 167 degrees. That is much higher then previous. My scoot usually idled around 130 degrees. I suggest all with high oil temps check their pump. Take the valve cover off and turn the engine over . you should see oil pumped into the rocker arms and cam bearings. If not then your pump is probably shot. I'm lucky I checked mine . any longer and my cam bearings would not of lasted. I had one last year. I was running just shy of 200F according to mine. itistheride.boards.net/thread/7041/product-review-tank-dipstick-gaugeI too would like to see more readings and less hearsay on the matter. Check this out . I remember inky Ben , he was a good guy. He also says temps should be lower . he says between 170-190 . scootdawg.proboards.com/thread/53895/oil-temp-dipsticks |

I think some buy these oil dipstick gauges and don't realize you have to adjust some of them. Then they install them and are like " these things are junk " you put the gauge in boiling water and adjust the face to the right calibration.

I imagine the oil pump wasn't exactly screaming "Hey, I'm broken!" either. By the time the scoot starts to act up, the damage is probably already done.

BTW you can test and calibrate your thermometer in hot vegetable oil using a candy or frying thermometer just to see where it lands when temps go over 100C. |

Cooks sometimes use ice water--- it'll read in the low/mid 30s(F*). I'm guessing the gauges don't go down that far, lol.

That's the thing, many may have bad oil pump and may not know it. Luckily my temps did not get to high ! These engines I'm sure are very touchy . I'm sure others have problems that are causing higher temps and they think that their temps are normal . there are many things that can cause this. Knowing the true normal temps will possibly make others realize there may be a problem. U hear others say " wow , 20k miles on your scoot" . that's because you don't see many make it that far. We now may know one of the reasons. When their scoots are running near 300 degrees f , and they pay no mind to it. Then one day " my engine is toast ! " hmmm I wonder why ? But like I said that's why we are here , to help others and to work with others to figure out what is normal and what isn't for these scoot. I believe we are at another one of those moments. |

But I guess if you mean , does it read the same in water and in oil ,yes that would work. I'm sure it will read 100% the same . I mean 200 degree water will read the same as 200 degree oil right ? ,lol Thats like the whole " what weighs more ? 10 lbs of rocks or 10 lbs of feathers ? " ,lol |

That way you'll know, for instance, where the dial would land if the temp actually was 230F. That would be good information to know and it may help shoot down naysayers that say it can't read over 100c. You could show that it can and does, and how. |

I already know it goes way past the 100c mark , but yes it would be nice to have it marked where like you said , maybe 230 or higher. |

I am of one of the Nay-sayers.....
Look, I have a drawer with 6 of them in it... I bought them way back when I first started my venture into upgrading anything on a scoot... In fact, they may have been my very first mod purchase... Everything I buy, I try to buy in bulk to get the best price...
Anyhow, I learned they're inaccurate... You can flick the thing and it will jump 15° and stay at that mark... In addition, mine leaked oil. Now, yours may be fine and functional.... But the bottom line is you have no idea other an educated guess about what's going on beyond where it's marked....
Seriously Geh, if ya wanna monitor you oil temps, get something like a KOSO sender and digital LED gauge and install it in the crankcase like you're supposed to... You can get the whole setup for around 50~60 bucks... And, if ya get a china based one, you get the sender and gauge for 15~20 bucks....
=========================
But, that's only half of what's going on this thread... Setting the oil gauge aside, this is your scooter you ride all the time and if you notice a big jump in temperature from where it's normally at, it doesn't matter what you're using to monitor to the temp if your results are able to be repeated. So, yes, if you've had a noticeable jump in oil temp, absolutely you need to investigate and get to the root cause.

So, yes, if you've had a noticeable jump in oil temp, absolutely you need to investigate and get to the root cause. That's no problem , we can disagree . I do agree that some of these gauges are probably junk . it happens with just about everything for these scoots. Like the cheap cdi's , some work some don't. The face on these gauges can turn left or right , that's how they Are calibrated, and if you flick the gauge and the face is looser then normal , I'd say yeah it will def jump. I'm going to do some test on my oil temps and let everyone know the true temps . I'm very confident that the results will come back that the oil temps are between 180 and 212f . trust me I have no hard feeling with those who disagree , we are only human. I believe that only a true test can determine what these temps will be. What has me convinced that the normal temps are lower then what many think are two things. First the cheap temp gauge: it has always read accurate whether in water or in my mouth " yes my mouth" and just recently when my oil pump stopped working it has skyrocketed . yes that's not hot enough to raise the needle past 100c but like I saready'd has recently almost constantly been above that mark. second if these scoots run near 300 degrees normally then how did I not burn my engine up running on a 2 hr round trip ? With a broken oil pump and the wrong fan cover ? My temps would have been near 400 f and that's oil temps . but like I said only a true test will tell the difference. I've already heard of two people who run without a cooling shroud and still are not at or above overheating. How is this ? It has to be because these scoots did not run as hot as what many think, but we will find out . and trust me if I'm wrong I will be the first to stand up and say I was wrong ,and if I'm right I will just present the numbers and that's that. That's the kind of person I am . Im not one of those " I told you so" or " are you for real" type of guys , I hate that , lol. As much as I looked I was not able to find a video showing the oil temp readings for these scoots. The only good video I saw was a video of someone who made there own temp setup with a warning buzzer that he set at 230f . then the video ended without showing the results . these are the reasons we need to have these disagreements and tests , because of all the contradictions and the wrong info being put fourth. Which will be wrong ? Maybe me, but it needs to be done. Let's say that the oil temps turn out to be between 180 and 200 . this will alert others if their engine temps are in the 250's and above , that something may be wrong. I also read that oil works best between 180 and 200 degrees , even though most vehicles run a little hotter . this should be an interesting test. I'd like for you to do a test also "if you like" , so we can compare our results. My oil pump will be here either 2mor or Saturday , so I will be read by the end of the weekend to do the tests. I just hope my cam bearings are ok . I didn't notice any noise coming from the cam , so it should be fine. I'll even record the test so no one can say anything about it. we should start a wager ,lol. |

Mine also leaked oil , lol . I also wanted to make sure the gauge was not somehow picking up heat from the header so I put the glass or plastic lens by the stove and melted the lens some ,lol . the funny thing is that it still read perfect in boiling water and what not.

I just found a positive video . I can say I pretty much know that the temps will be between 180-200f . check this out !! This is a video . he took the temps of the oil cooler line in and line out. This is after a 30 min ride !! His temps are around 179 f and the cooler drops the oil the around 150f this is a true test. So the oil coming from the engine case is around 179 and I'll even add ten due to the oil travel from the crank case to the cooler , so let's say 190f on an 80+ degree day after a 30 min ride . this is proof .

Remember the cooler only drops the temp by around 20degrees so the temps will be between 180-200 , depending on if you have an oil cooler or not, like our old friend inkynben said.
Edit: its actually 179-149 difference. So its a 30 degree difference which puts the normal temps near 200f . mine read 212 , so this is a near perfect test! .
We also need to take into.consideration whether or not this is a nodded Zuma or not . I'll send if I can find out .
