Community comparison picks for Gateron Oil King.
The Yellow is the budget smoothness benchmark; the Oil King is the premium step up — smoother stock, heavier, and far thockier thanks to the ink housing.
The MX Red is a lighter, scratchier classic linear; the Oil King is dramatically smoother and deeper-sounding for sound-focused builds.

Quick Summary
The Gateron Oil King review consensus is simple: this is one of the best stock linears you can buy. Factory-lubed, with a Nylon PA66 top, an Ink-blend bottom housing, and a POM stem, it delivers a glassy-smooth 55g stroke and a deep, thocky sound that usually demands hand-tuning on cheaper switches. It is the obvious pick if you want a premium linear that performs straight out of the bag.
Specs and Feel
Actuation is 55g with a ~65g bottom-out over the standard 4.0mm travel, a comfortable medium weight that some owners find a touch heavy for alphas but ideal for spacebars, mods, and full builds. Smoothness is the headline, and it is the trait reviewers return to over and over: owners repeatedly describe these as the smoothest switches they have ever used, with minimal scratch, low wobble, and no spring ping straight from the bag. The 20mm black-plated spring keeps the return snappy, and the Ink bottom housing is what gives the Oil King its darker, fuller acoustics, frequently called thocky and crisp at once. The one recurring gripe is factory-lube consistency: a minority of buyers report batches with lube applied a little too thickly (an audible squish on the stem) or unevenly enough that the odd switch reads slightly scratchy. It is not widespread, but worth knowing.
Tuning
Because they are factory-lubed and already smooth, most builders skip hand-lubing entirely; many describe them as feeling hand-lubed stock. If your batch shows the thick-lube squish a few owners mention, a quick bag-lube of the stems with 205g0 evens it out and a pass on the springs kills any ping. Film only if you find housing wobble; they are MX-compatible and hot-swap friendly.
Verdict
If you want a premium linear that sounds and feels great with zero work, the Oil King is a top recommendation, and owner ratings sit close to perfect. Choose a budget linear like the Gateron Yellow only if cost matters more than the last few percent of smoothness and that signature thock. The Oil King is, as more than one owner puts it, the switch reds and yellows wish they were.
Frequently asked
Are Gateron Oil Kings smooth out of the box?
Exceptionally. They ship factory-lubed with a black-ink housing and POM stem, giving one of the smoothest stock strokes available. Most people never bother hand-lubing them.
What do Gateron Oil Kings sound like?
Deep and thocky. The ink housing produces a darker, fuller sound than nylon or polycarbonate linears, which is a big part of their popularity for sound-focused builds.
How heavy are Oil Kings?
Medium. They actuate at 55g and bottom out around 65g over 4.0mm travel: heavier than a Gateron Yellow, lighter than a true heavy linear, which lands in a comfortable middle for most typists.
