When we get into our vehicle, everything is usually second nature. Starting the engine, listening to the gentle purr of the motor (or the load roar depending on your equipment), followed by looking at all the gauges on the dash to make sure everything is working as intended.
We rarely give a lot of thought to what’s going on beneath the hood. Even those of us who are automobile aficionados and give great care to our cars’ inner workings don’t usually worry unless something is wrong.
But what if one of those gauges reads that something is wrong? What if your oil pressure is high or low? What does it mean? And what can you do to fix it?
Don’t Think Oil Pressure Matters? Think Again
Some people ride their vehicles for miles, across months and even years, even if there are problems that need fixing. Sometimes it is a lack of knowledge about how to fix it, while other times people assume the issue can’t be that bad if the vehicle is still running.
Oil pressure is critical when it comes to internal combustion engines. Given that these engines are still widely used in cars, despite some modern alternatives taking spots in the market, it is important to make sure you know how to care for them.
When we start our vehicle and hear the engine, it is easy to overlook all the complexities that are just out of sight. With so many parts working together and at such a frantic pace, it gets hot quickly. But in addition to heat, your engine must also be able to fend off the constant threat of metal-on-metal. When parts collide with one another repeatedly, it can easily wear down your car’s critical components over time.
That being said, how exactly does oil pressure factor into it? Oil is used to lubricate components within your vehicle. It is picked up by a pump and transported through passageways into bearings. Having the right level of oil pressure ensures that the metal on parts like the rotating shaft and bearing shell don’t touch beyond the initial startup and shutdown procedures.
Not only does this cut down on metal-to-metal contact, but it helps keep the engine cool by minimizing friction between moving parts and even stationary parts that can heat up quickly by being too close.
In order to make sure your oil pressure is safely in the median range where it is recommended to be, you need an oil pressure gauge – but which is the best one?
Finding the Best Oil Pressure Gauge: How We Choose Our Ratings
When it comes to finding the right oil pressure gauge, a lot is at stake for the buyer. You’re not just spending money on a product – you’re spending money on a product that will provide critical information about your vehicle’s performance.
When we factor in the best characteristics of oil pressure gauges, we won’t worry about the installation process – while that is important in some ways, we’ll focus mainly on two characteristics. The first is how easy it is to read.
Many people dislike having an abundance of gauges in their car. It seems like each one is centered around a different unit of measurement and those who aren’t vehicular experts may find two many gauges are just as bad as not having enough. We’ll focus on gauges that provide you the information you need without requiring you to decipher anything.
The other factor that we will take into heavy consideration is cost. When you’re investing in an oil pressure gauge, you’re investing in your vehicle’s future – but that doesn’t mean you have to empty your bank account.
Keeping in mind that there are plenty of big-name brands out there offering quality oil pressure gauges, we’ll rank them – here is our personal top ten.
Best Oil Pressure Gauge Choices: Which Model Made the Top 10?
Straight away, we’ll make note that this isn’t the cheapest one on our list. How can it be the top spot if we’re going by cost-efficiency? For one, we’re also going by how easy it is to read. And with a clear list of increments ranging in multiples of 10 up to 60, this one makes it easy to see where your pressure is.
But it’s the number of great reviews it has gotten that makes this product so worthwhile. With durable stainless-steel housing material and solid brass internals, the 1.5-inch diameter gauge is reliable in both its accuracy and its longevity. It will last you, and provide accurate readings. Not bad for $50!
Not bad at all – and that’s putting it mildly. With this gauge, you get a reliable product that can be used to help you keep an eye on your oil pressure easily. It will also hold up well over time, making it a smart long-term investment.
This one costs around $20 depending on where you shop. And while it doesn’t have the sleek looks of the ACCEL, it does have one clear advantage – it measures oil pressure on a scale of 0-100 PSI. This time, they’re separated in increments of 20, with three markings in between each so you can be a little more accurate with your readings.
The plain white face and black numbers may seem bland for some. But for others, the 12-volt internal lighting sets it off nicely and makes for a basic but rugged look. It’s designed for negative ground systems, and comes with the tubing and thread fittings necessary for installation.
If you like a back-to-basics approach when it comes to looks, this is a great gauge to choose. It’s also gotten plenty of positive reviews, a testament to Sunpro’s engineering mastery when it comes to this type of product.
