Editorial Review

The Oil King earns its name. Factory lubed with Krytox 205g0 from JWK's production line, these switches are designed to be drop-in ready without any additional preparation. The combination of a UHMWPE stem — the same ultra-low-friction polymer used in Alpaca V2 and Boba U4 switches — with a Nylon housing creates an acoustic profile that is notably thocky for a switch at this price point.

Smoothness out of the box is the Oil King's primary selling point. UHMWPE is one of the lowest-friction materials used in switch manufacturing. Combined with a quality factory lube application, the stem glides through the housing with virtually no tactile friction. This is not just "pretty smooth for the price" — it is smooth in absolute terms, comparable to hand-lubed mid-range switches.

At 55g actuation and 65g bottom-out, the Oil King sits in a medium-weight zone that works for both typing and gaming. It is heavier than the Gateron Yellow family but lighter than heavy tactiles or springs like the Creams. This makes it versatile without being exceptional in any particular direction. The 10g spread between actuation and bottom-out is smaller than some linears, giving a relatively consistent force curve throughout travel.

Sound is deep and thocky courtesy of the UHMWPE stem damping vibration differently than POM or Nylon stems. The Nylon housing adds a slight higher-frequency component that prevents the sound from becoming overly muffled. The result is a switch that sounds expensive in most test boards.

Some users find the factory lube inconsistently applied between batches. If you get a batch that feels less than ideal, a quick re-lube session corrects this immediately. Even accounting for occasional batch variation, Oil Kings represent exceptional value for a pre-lubed switch and are a strong recommendation for builders who want quality without the prep work.

Frequently Asked Questions

Are Oil Kings smooth out of the box?
Yes, Oil Kings are among the smoothest factory-lubed switches available. JWK applies Krytox 205g0 in production, and the UHMWPE stem has inherently low friction. Most users find no need to re-lube after opening the bag. Occasional batch variation exists, but the vast majority of buyers report smooth stock performance.
Do Oil Kings need more lube added?
Most do not. If you get a batch that feels slightly rough or inconsistent, a light re-lube with 205g0 on the rails brings them to peak performance quickly. For builders who want to maximize smoothness, re-lubing even well-lubed Oil Kings is not harmful and ensures total coverage. Otherwise, they are genuinely ready to install.
What makes Oil Kings sound thocky?
The thocky sound comes from the combination of UHMWPE stem material, Nylon housing, and factory lube. UHMWPE dampens stem vibration differently than POM, contributing to a lower-frequency sound on downstroke. The Nylon housing adds body to the sound. Together with the lube coating reducing high-frequency scratch noise, the result is a clean, deep acoustic profile.
