Choosing Your Oil: Synthetic vs Conventional
As with the classic TC, you can use the same oil in your Milwaukee 8. But should you go synthetic or conventional? Here’s what you need to know:
- Synthetic oils offer better performance, protection, and longevity compared to conventional oils.
- Your engine won’t run any different or last one mile longer just because you spend more on oil.
- However, using the correct viscosity oil and changing it at the recommended interval is crucial.
Pick your favorite brand of synthetic oil (20W-50) and keep your engine purring like a happy kitten.
Transmission Oil: Should You Use the Same Synthetic Oil?
Now let’s talk about the transmission. You may be wondering if you can use the same synthetic oil in the transmission (e.g., Amsoil). While you can, gear oil would be better. Even the MoCo has started offering gear oil, and Mobil One has 75W-140 available at your local Wal-Farts or Vato Zone.
Amsoil: The Triple Threat
For those who swear by Amsoil, the Amsoil V-Twin 20W-50 for the engine, Amsoil V-Twin Primary Fluid, and Amsoil V-Twin Transmission Fluid are the way to go. Change all three at 5,000 miles, even though you could go longer on the transmission – One quart – no big deal. And, of course, change the oil each spring, regardless of mileage.
Oil Filters: K&N KN-171b and Other Choices
Now let’s talk about oil filters. The K&N KN-171b is a popular choice, but any good quality filter designed for the application will work just fine. Remember, you’ve spent thousands on your bike – don’t go cheap on the oil and filter.

However, some may question the need for a stabilizer – it’s always good to research if you really need to use one. An additive was also used, to switch it up you can use Slick 50.
With this option, you won’t even really need drain plugs as often. Just let a quart run through your bike every few thousand miles, and you’re good to go. But you shouldn’t even neglect the need to replace filters regularly as part of the maintenance schedule.
