I'm only asking because I couldn't find an oil guage that read in deg F** A: As long as the gauge reads in the temp range that you want, I don't see why the sensor wouldn't work. It's immersed in a liquid, so shouldn't matter whether coolant or oil. **Q: This is going on a 1973 bug what is the limit on how hot the gauge can go? I've read 3?? can you please just let me know normal temp is 300 to 310** A: No offense, but a '73 bug is an air-cooled engine. This is designed to monitor the cooling water for a water-cooled engine, and it has an alarm at 212 degrees F. On an air-cooled angine, you can only monitor the oil temperature or the cylinder head temperature. **Q: Why does the temp stay at 104 ? I checked it with a lazer thermometer and it reads higher than that** A: That is the starting reading 104 does not read lower **Q: I installed this gauge recently and now gauge is locked at 304 reading. Is it thegauge or sender?** A: Please check the sensor installed correctly,and if it still display304 please contact us again,click link below,We will offer a good solution https://www.amazon.com/ss/help/contact/?_encoding=UTF8&marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=A23ZC5CAWCCWWE ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***R on January 30, 2022* ### ⭐⭐⭐⭐⭐ Review *by D***F on July 28, 2021* ### ⭐⭐⭐⭐ Review *by K***R on August 16, 2020* ## Frequently Bought Together - HOTSYSTEM Universal Water Temp Gauge Temperature Meter Electronic Blue Digital LED DC12V 2inches 52mm for Car Automotive(Fahrenheit) - HOTSYSTEM Electronic Voltmeter Voltage Volt Gauge Meter Blue Digital LED 2inches 52mm for Car Vehicle Auto - ESUPPORT Car 2" 52mm Digital Oil Press Pressure Gauge Blue LED --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1218540-universal-water-temp-gauge-temperature-meter-electronic-blue-digital-led](https://www.desertcart.co.uk/products/1218540-universal-water-temp-gauge-temperature-meter-electronic-blue-digital-led) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-22*
