Biker’s Choice Oil Tank Dipstick Temperature Gauge For Harley-Davidson Softail (2000–2017)
Direct-Fit Functional Upgrade & Accurate Real-Time Engine Thermal Monitoring
Keep precise tabs on your engine oil temperature and prevent thermal stress with the Biker’s Choice Oil Tank Dipstick Temperature Gauge. Specially engineered for 2000 through 2017 Harley-Davidson Softail models, this dual-purpose accessory replaces your factory oil plug with a high-visibility, analog temperature gauge topped with a show-quality chrome cap.
Monitoring oil temperature is essential for maintaining proper oil viscosity and preserving air-cooled Twin Cam 88, 96, 103, and 110 engines—especially during hot summer rides, parade duty, or stop-and-go traffic. Featuring clear Fahrenheit temperature markings and high-temp glass, this dipstick allows you to check oil levels and thermal health at a glance without needing electrical wiring or handle-mounted gauges.

Design Highlights & Engine Health Protection
### Clear Analog Thermal Monitoring
Air-cooled Twin Cam engines generate significant thermal load. Excessive oil temperatures breakdown oil film strength, leading to premature ring, bearing, and valvetrain wear. The Biker’s Choice analog gauge features a high-contrast dialface and a durable, vibration-resistant needle that gives you instant thermal feedback whenever you come to a stop.
### Leak-Free Precision Fitment
Designed as a direct press-and-twist replacement for the stock push-in oil tank cap, this gauge includes a high-grade Viton O-ring seal. The seal resists degradation from hot motor oil and fuel fumes, maintaining a tight hydraulic seal that prevents oil mist from spraying onto your side covers or rear frame.

Step-by-Step DIY Installation Overview
Installing the Biker’s Choice Oil Dipstick Temperature Gauge takes less than 5 minutes and requires no special tools.
### Required Tools
- Clean Shop Towel / Lint-Free Microfiber Cloth
- Fresh Motor Oil (for O-ring lubrication)
### Step 1: Removing Factory Dipstick
Ensure the motorcycle is parked on level ground. Unscrew or pull out your stock oil tank dipstick and wipe the filler opening clean to remove dirt or road grit.
### Step 2: Stem Marking & O-Ring Prep
Compare the oil level fill marks on the new Biker’s Choice stem with your original OEM dipstick to confirm full/add level markings match. Lightly lubricate the rubber Viton seal on the new gauge with a drop of clean engine oil.
### Step 3: Installing & Testing
Push and twist the Biker’s Choice temperature dipstick firmly into the oil tank fill neck until fully seated. Start the engine, run it up to operating temperature, and check the dialface to verify smooth gauge needle operation.
Frequently Asked Questions
### How accurate is an analog oil tank dipstick gauge?
Because the temperature sensing probe sits directly submerged in circulating motor oil inside the oil reservoir, it provides an accurate reading of bulk oil temperature (typically within 2 to 3 degrees of digital sensors).
### What is the normal operating oil temperature for a Twin Cam Softail?
Normal operating oil temperatures for Harley Twin Cam 88, 96, 103, and 110 engines typically range between 200°F and 230°F (93°C to 110°C). Temperatures exceeding 250°F (121°C) indicate high thermal stress where synthetic oil protection or an oil cooler is recommended.
