TC-W3 Oil – What Is It and Why It’s Needed

To understand what TC-W3 oil is, you have to take a look at all the components in its name and understand them. Basically, TC is short for two-cycle, meaning that the oil is a two-cycle one. The W comes from the fact that the oil is water-cooled, whereas the 3 means that it is the 3rd formulation of oil for a two-cycle, water-cooled engine.

This oil formula has been made in order to keep outboard engines running strong while reducing the bad impact they have on the environment. Although many people thought the oil-fuel mixture would be forgotten as it’s harmful to nature, some brands came up with the idea to create a formula that protects the environment too. That being said, the TC-W3 oil formula was born.

What Features You Should Consider When Shopping for 2 Stroke Outboard Oils

It’s always important to be well-informed before going shopping because otherwise, you risk ending up with an improper product. After all, you can’t get a 4-stroke oil for your 2-stroke engine. So, no matter if you’re looking for marine battery chargers or even a new motor, you must be properly informed.

So, keep in mind that the best oil will keep your outboard strong and durable. Here are some features to take into account before you get that new 2 stroke outboard oil.

  • Price

You will notice that prices vary for 2 stroke outboard oils, depending on how good they are, or where you get them from. Sadly, many of them tend to be overpriced. While in some cases the price is well-deserved, some products tend to raise prices while the product leaves much to be desired. When you look for outboard oil online, the best thing to do is to check the reviews and see if the price is worth it. If the price is too high yet people are complaining about the results, it’s best to avoid that product.

  • Synthetic or not?

Even 2 stroke outboard oils come in multiple types, believe it or not. You need to think well about the type of oil your outboard will need, especially if you want to maintain it and keep it working for a long time, saving on reparation bills.

One of the types is synthetic two-stroke oil. It has a lot of benefits for 2-stroke outboards because it can provide some extra lubrication and increase combustion. To make things even better, this oil can keep your engine clean. Every part of the outboard will be clean, even the nuts, bolts and piston. This oil can be quite pricey, though.

If you don’t get a synthetic one, there will be more risk for your outboard and you may have to either repair it quite often or look for a new one when it stops operating properly.

  • Non-Smoke and Odorless

The last thing you want from your outboard is for it to produce smoke, whether you’re using 2-stroke or 4 stroke outboard motor oil. Smoke is usually caused by a two-stroke oil buildup that settled on the crankshaft area’s bottom. That’s exactly where your engine is situated, and it means the fuel has been burnt on combustion. That will cause a lot of smoke, and a bad smell too, and you want to prevent that.

This is why you must look for an oil that prevents the apparition of smoke. Many products specify this feature in the description, but it’s also best to check the reviews too and ensure it works before you actually buy the oil.

  • Versatility

Although 2-stroke outboard oil is meant to only be used for outboards, there are oils that can be used for other motors as well. Having said that, some oils can work for your motorcycle, jet skis and many other units. If you find an oil that is suitable for those units as well, that’s even better.

  • Certification

As with everything related to marine equipment, you need something of high-quality. In this case, certification is something to take into account. It’s important to check whether your oil carries either a Jaso FD or an ISO-I-EGD certification. Although you can also settle for a cheaper one with API-TC standards, it’s better to go for something safer.

What Are the Pros of Using 2 Stroke Outboard Oil?

8 Best 2 Stroke Outboard Oil - (Reviews & Buying Guide 2021) (17)It’s always important to know the benefits of using 2 stroke outboard oil, especially if you want to pick a good one. As such, here are the pros that come with this outboard oil type:
