Toro 21464
Engine oil for the Toro 21464
Short answer
The same three oil numbers on all eight listings. Ten other accessories come and go across this machine’s serials — the oil is not one of them.

What decides it
The numbers that matter here
- Serial range
Does not affect the oil on this machine
Stated plainly because four other machines on this site do change their synthetic at a serial. Here the same three numbers run through every listing, so you can buy oil without finding your serial.
- Grade
SAE 30 (38903, 38916) or full synthetic 10W-30 (138-6053)
Both grades sit side by side on every listing and Toro says nothing about choosing. SAE 30 is a mono-grade for warm running, 10W-30 a multi-grade; your climate and your engine manual decide, not the listing.
- Bottle size
32 oz (38903) or 18 oz (38916), same grade
A quantity decision, not a fitment one. With no published sump capacity, neither bottle is “an oil change” until you have checked the manual.
- The block that is not a boundary
Ten numbers enter at 411986087 and leave at 418280833 together
Worth knowing before you draw a conclusion from it. Unrelated parts moving in step is a page being rebuilt, not a machine changing, and none of the oil numbers move with them.
In detail
Choosing engine oil for this mower
On the 21464 the oil does not move, and this machine is a good place to show what “does not move” is worth.
All eight listings name accessories, and every one of them names the same three oil numbers: 38903, SAE 30 in a 32 oz bottle; 38916, the same grade in 18 oz; and 138-6053, the full synthetic 10W-30. The older synthetic 117-0066 is named on none of them. There is no serial on this machine at which any oil number enters or leaves.
Around that, plenty moves. Ten numbers — nine of them not parts for this mower at all: a snow blower, a leaf blower, a string trimmer, a hedge trimmer, a chainsaw, a charger and three batteries, plus a second cover — all appear together at 411986087 and all disappear together at 418280833. A block that large arriving and leaving in step is Toro rebuilding a page’s cross-sell, not a change to what the mower takes, and this site does not record it as a boundary. If you are scanning listings for the serial where something changed, that block is the thing most likely to catch your eye and least likely to mean anything.
What does change on the 21464 is the discharge chute, once. 139-6556 is named on every listing but the newest, and 147-8696 on the newest alone, from 418280833. That single break has its own page under this model’s serial ranges.
Toro publishes no sump capacity here, so how much oil the engine takes is a question for the engine manual rather than for a parts listing.
The mistake we see most
Method
How we established this
We opened all eight listings Toro publishes for model 21464 and recorded which oil numbers each names, then opened the product pages for the three it names. The block of ten was read off the same matrix: each of those numbers is named in exactly the runs 411986087–412999999, 413000000–415499999 and 415500000–418280832, and in no other.

The answer is not the same on every machine, which is the point of checking rather than assuming.

SAE 30 4-Cycle Lawn Mower Engine Oil 32 oz (Part # 38903)
The Toro Company · Primary source · Accessed August 29, 2026
The number requested, answered without a redirect and with no “Replaces Product” line in either direction. Toro describes it as a mono-grade fluid for high-temperature use and states it “meets or exceeds performance requirements of all OEM products (Toro®, Briggs & Stratton®, Kohler®, Honda® and Tecumseh®)”. It names engine makes and no machine, model or engine number, so it establishes the product and not the fitment.

SAE 30 4-Cycle Summer Engine Oil 18 oz. (Part # 38916)
The Toro Company · Primary source · Accessed August 29, 2026
The number requested, no redirect and no “Replaces Product” line. Same mono-grade SAE 30 description as 38903 and the same list of engine makes, in an 18 oz. bottle rather than 32 oz. The page is marked “Not Available Online”, which is a statement about Toro’s own checkout and not about whether the oil is listed for a machine. This is the bottle kit 20298 itemizes.

OIL-30/10W-30 SYNTHETIC CK4 [QT] (Part # 138-6053)
The Toro Company · Primary source · Accessed August 28, 2026
The same page served at its own number, and it is the same page carrying that one “Replaces Product 117-0066” line — so Toro states the supersession once and either number reaches it, which is not the same as stating it from both directions. This page is now also the source for part 138-6053 itself: batch 13 created the pt_engine_oil category, so the clause that used to sit here — that engine oil is in no category this site records — stopped being true the moment that batch was staged.
