The JRP Edge 52mm Digital Oil Temp Gauge in Fahrenheit is the ideal tool for monitoring your engine’s oil temperature, whether you’re driving a petrol or diesel vehicle. With a range of 0-300°F, this gauge ensures you can keep track of your oil temps, preventing overheating that can lead to oil thinning. Whether you're running a track car or a weekend warrior, keeping a close eye on oil temperatures is critical. While your water cooling system might hold up during long sessions at the track, engine oil is a different story. It can heat up quickly, potentially reaching temperatures where it loses its ability to lubricate and oil pressure drop, leading to serious issues like a spun bearing as just one example.
Monitoring oil temps and setting up a warning for when they get too hot is one of the best ways to ensure your engine remains protected, even during intense driving. Couple that with our CPW – Color Pre-Warn system, which will indicate oil temps are getting outside of normal operating parameters long before you hit that hard final alarm allows you to drive by gauge, using your peripheral vision, and as the gauge starts to change color, you know you are starting to push the engine well before any damage may occur.
Our Fahrenheit oil temp gauges offer a range of advanced features. The bright and easy-to-read LCD display allows you to set up a warning system, alerting you when the oil reaches a dangerous temperature. You can also track peak oil temps, so after a run, you can review how hot your engine oil got during the session. These 52mm oil temp gauges come packed with useful features, including a 52mm gauge pod, a pillar mounting kit, and an external settings button for easy adjustments.
While these gauges are a favorite among performance enthusiasts, they’re also useful for 4x4 diesel drivers who want to monitor oil temperatures during heavy towing or off-roading. Though more popular with track-day drivers, these oil temp gauges offer value to both performance and off-road customers, providing reliable monitoring no matter the vehicle type.

COLOUR PRE-WARN
At JRP we are always trying to innovate, and with our deeper than most understanding of the intended use for a gauge and it’s practical function, we always ask ourselves in the development stages how can we make this better. It’s really the heart and soul of what we do here.
So when looking at our 52mm temperature based gauges, we asked ourselves once again how can we make these better for our customers, expand their practical functionality in ways that are actually useful. With the gauges using an incredible 10-colour LCD panel, our engineer put his thinking cap on and came up with a function we call Colour Pre-Warn or CPW for short. Typically gauges will come with one warning you can set and that is it, you would set the warning to go off at a level that is either right on the limit, or because you only have the one warning, you end up being conservative with it and set it lower because you would prefer being warned before it gets to out of control. This normally leads to having alarms going off all the time because you are cautious, or you end up getting sick of being cautious and set alarms a little too aggressively and end up letting a high temp situation get out of control and engine damage happens. We have all been there one way or another.
With the JRP Edge v1.5 temperature gauges, you now have a two stage warning system, one which works the same as other gauges where you set a final value for a warning that will trigger an alarm on the gauge, but now there is a softer secondary warning system you can choose to enable which will pre-alert you that the gauges are reaching higher levels than normal and alert you using the gauges bright colours.
So for example, you have chosen to run blue as your desired running colour for the gauge, set yourself a warning at 210 °F for oil temp, if you enable the “colour pre-warn” function, once the gauge reaches 180 °F it will change from blue to yellow, and once it hits 191 °F it will change from yellow to orange, and once you hit 201 °F it will change from orange to red, and finally once you reach that 210 °F the gauge will sound an alarm.
The idea behind this is you get a visual non invasive indication that the temp gauge is moving out of normal operating parameters, this allows for a more aggressive final audible warning to be set, along with being visually alerted that your temps are starting to move into high territory’s without nasty loud alarms going off. You will be pre-warned by the gauge changing colour that things aren’t quite right and gives a larger margin for error in catching an event well before it happens.
Now just like everything we do here, we have put a decent amount of thought in how this little function was implemented and could be setup. You are able to customize the colours in the pre-warn function, you can select any 3 colours that you aren’t using as a running colour for the gauge for the warning system. You can also set how sensitive the colour pre-warn is in relation to your primary audible warning you set, we have really tried to make it so setup of this feature is simple, yet it can be customized to suit almost all applications.
We have a video demonstration of the feature in action on this page, just click the Videos tab at the top and you can check it out and see how it works. We feel this feature while sounding simple enough is actually going to become something that a lot of our customers will come to love, no more gauges alarms going off prematurely, no one likes premature alarms, less anxiety around looking at the gauges more than you need to making sure everything is ok and your ears aren’t about to get a pounding, we feel it will be one of those features that on paper you think that’s cool but almost a bit gimmicky, to using it and finding out that it’s been one of the best little innovations you have found in a gauge for years.
HIGH QUALITY SENSORS
The JRP Edge 52mm digital oil temperature temp gauge come with a 2-wire fluid temp sensor, these sensors ground using the gauges main ground instead of where the sensor is installed like single wire temp sensors. We have found the 2-wire oil temp sensors to be more accurate than the single wire sensors and is why we only use 2-wire sensors with all our gauge products.
We have been in the gauge & wideband business now since 2016 and in that time, we have been devoted to offering accurate and reliable gauge products for the performance car market, and the diesel on-road and off-road customer base. We here at JRP know that customers when buying a gauge are looking not only for a product that looks nice, but they need to be able to rely on the sensors being accurate & reliable. Our mission has always been to supply amazing looking products, but with a strong focus on function and quality sensors without asking customers to pay a fortune. The Edge range of gauges is no different, you can rely on them being tough & accurate with peace of mind you will not be having to replace sensors or the gauges due to poor quality, buy once buy right.
AMAZING LCD DISPLAYS
The crown jewel of the Edge 52mm range of gauges is their amazing VA type LCD panels that were developed just for these gauges. As soon as you see them light up you will know right away these are not your typical LCD gauge, they have an amazing clarity & brightness to them.
The LCD panels used in the JRP Edge range of gauges took over a year in development process, they are a high end VA type panel which allows for superior viewing angles and brightness, the first thing you will notice about the JRP Edge gauges is how they can be viewed quite clearly on both on & off angle viewing, one of the shortfalls of LCD is as you view them off angle their brightness and clarity reduce, the JRP Edge have some of the best off angle viewing of any LCD gauge on the market today.
They have a brightness of 600nit which is also terrific, daytime viewing on some LCD gauges can be a little poor due to lack of brightness, this is not the case with the Edge range of gauges, and they are clear and easy to read in almost any condition. Also having such a large number of selectable display colours means it will be much easier to match factory instrument clusters for those customers who want to maintain a consistent look in their cabin.
High End Build Quality
The Edge range of gauges have a robust design, the body of the gauges are a tough light weight alloy finished in a polished black look which gives them a nice contemporary look which will suit almost any application. These gauges also use a thick single piece scratch proof tempered glass panel in front of the LCD screen which slightly protrudes from the gauge itself for an awesome look that just screams quality. There is nothing worse than gauges that just look cheap, and the last thing the Edge range does is look cheap, they have a modern look which is also supported by quality housing and glass which just gives them that overall feel and look of quality.
SINGLE POWER INSTALL
All of our Edge 52mm digital oil temperature gauges have the Power Link feature and cable included, this is a simple way to provide power to more than one gauge with just a single link cable running from the primary gauge to any additional gauges. This is to save having to run multiple power looms for each gauge you have installed and reduced the soldering / crimping of power looms down to just the primary gauge itself. For any additional gauges you want to install, it is just a case of running a power link cable from one gauge to the next. It is a pretty simple concept, but definitely makes installing 3 or 4 gauges a much quicker and neater process having the feature be on the gauges.
REMOTE CONTROL
While the gauges themselves have a single button on the gauge body itself which is used for making changes to the gauges settings, such as colour selection, warning values, viewing or clearing peak values, each Edge 52mm oil temp gauge comes with an external cabled button controller which can be installed somewhere tucked away in the cabin for making changes to the gauges settings after installation without having to remove the gauge from its housing to make the changes. Just simply connect our little button controller to the gauge and install somewhere easy to access, be it hidden away, or you can install it into your dash for the race look. Updating the gauges warning settings, changing colours, viewing or resetting peak values will no longer be a hassle at all.
WARNINGS & PEAK VALUES
All the Edge range of 52mm gauges have the feature to set warnings on the gauges, it’s an important part of any decent gauge solution for users to be able to configure their own warning values, and the Edge 52mm digital oil temp gauges have this covered. The gauges have a built in buzzer that will alert your set temperature for a warning has been triggered, and a nice little warning symbol on the gauges screen, if your vehicle ends up running crazy hot oil temps you oil can start to thin out which can lead to major engine damage, so with the warning set the gauges will let you know if this ever happens. Another feature some customers may find useful is the gauges are able to record peak temperatures, this will enable you to check what is the highest oil temps seen by the gauge at any time without having to worry about looking at the gauge all the time.
