Toro 20334
Fuel treatment for the Toro 20334
Short answer
130-2393, the 0.5 oz packet, and on newer machines 131-6572, the 12 oz bottle. On three middle ranges the packet is sold only inside a kit.

What we have verified
What decides it
The numbers that matter here
- Which number
130-2393 throughout; 131-6572 only on the four newest runs
The packet is named on ten of this machine’s runs — seven on its own card and three inside kit 20234. The 12 oz bottle is named on four, all of them 404320000 and above plus 400000000–401999999.
- If your serial is 313000001–314999999
The packet is inside kit 20234, not on a card of its own
Toro names 130-2393 there only in the kit’s description. You cannot buy it separately from that page, and a kit’s contents can change without its number changing.
- If your serial is 402000000–404319999
Your listing names nine accessories; its neighbours name sixteen
The 12 oz bottle is missing from your run and present on the runs directly below and above it, along with six other numbers that leave and return together. Read the neighbours, not this page alone.
- 131-3823 is not a third treatment
It is ready-mixed fuel, and it travels with the 12 oz bottle
It appears and disappears alongside 131-6572 on every run here, which is what makes it look like one. Toro’s own page for it describes fuel rather than an additive.
In detail
Choosing fuel treatment for this mower
Toro lists two fuel treatments for the 20334: 130-2393, a 0.5 oz packet, and 131-6572, a 12 oz bottle. Which of them your own listing names is the whole of this page, because on this machine the answer changes four times.
Across the fourteen listings Toro publishes, this part is in four different conditions. On the four oldest runs it is **not named at all**. On the next three it is named **only inside another part**. On three after that it has **its own card, the packet alone**. On the four newest it has its own card with the **12 oz bottle beside it**.
**The middle three are the ones worth knowing about**, 313000001 through 314999999. Those pages sell engine maintenance kit 20234, and the kit's own description itemizes what is in it: 20 oz of SAE 30 engine oil, a spark plug, an air filter, and a 0.5 oz packet of fuel treatment, that packet given as 130-2393. There is no fuel-treatment card on those pages. The number is there, on the page, and it is not something you can buy on its own from it.
This site records those three ranges as conditional rather than confirmed, for two reasons. Toro is not selling you the treatment there, it is selling you the kit. And **a kit's contents can change without its number changing**, so what arrives in a 20234 today may not be this packet.
**The 12 oz bottle is where a serial lookup will mislead you.** 131-6572 appears at 400000000, is absent from 402000000–404319999, and is back at 404320000. As a statement about the mower that is nonsense: a bottle of fuel treatment does not stop suiting a machine and then start again. As a statement about a page it is obvious. **Seven numbers leave that listing together and the same seven return** — both engine oils, the mesh bag, the grass bag, the ready-mixed fuel and the 12 oz treatment among them. The run names nine accessories where the runs either side of it name sixteen.
One number on those pages sits beside the treatments and is not one. **131-3823 is All Season 4-Cycle Fuel** — fuel itself rather than something added to fuel, which is what its own product page settles. It arrives and leaves with 131-6572 on every run of this machine, which is exactly what makes it easy to mistake for a third treatment.
Toro publishes no dosage on any of these listings; its description for the packet points the reader at the product label instead. The packet is one dose and the bottle is not, so the two are not the same purchase in different sizes.
The mistake we see most
Method
How we established this
We opened all fourteen listings Toro publishes for model 20334 and recorded which fuel treatments each names, counting a number sold on its own card separately from one named only inside another part’s description. The 402000000–404319999 run was re-opened on 30 August 2026 together with the runs either side of it, and the seven numbers that leave and return were established by comparing the full accessory lists rather than by looking up the treatment alone. The kit’s contents were read from the 313000001–313999999 listing, where Toro prints them.

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

Toro’s official parts listing for the earliest of the three ranges we verified. Lists 20234 (Engine Maintenance Kit for Briggs & Stratton Engine) and 108-8120 (TRACTION ASSIST KIT [PPG2]). Also lists 38991, 59534P, 59502, 59503 and 490-7462. The range selector on this page names thirteen further serial ranges for the same model number.

The next published range. Lists 130-8148 (Briggs & Stratton EXi Engine Maintenance Kit Replacement) and 131-4590 (Traction Assist Handle) where the previous range listed 20234 and 108-8120. Still lists 59502; 137-4833P does not appear.

The later range. Still lists 130-8148 and 131-4590, so the maintenance kit does not change again here. It lists 137-4833P (8 Inch Front Wheel) and does not list 59502 — a second, separate boundary within the same model number.

Engine Maintenance Kit for Briggs & Stratton Engine (Part # 20234)
The Toro Company · Primary source · Accessed August 31, 2026
Toro’s product page for the kit, and one of the few in this family that is a page for the number requested rather than for a part replacing it. It itemizes the kit: 20 oz. SAE 30 engine oil (120-3306), a spark plug (120-3305), an air filter (120-3303) and a 0.5 oz. packet of fuel treatment (130-2393). It carries no line saying this kit replaces another number or has been replaced by one. **Re-read 31 August 2026 and unchanged in every particular, including the 0.5 oz.** — which matters, because the page Toro serves for 130-8148 gives the same packet as .05 oz. Two further details this record had not held: the internal designation TORO WPM MAINT KIT - BRIGGS, and a Specifications row reading Service Pack Yes.

All Season 4-Cycle Fuel for Lawn Mowers and Snow Blowers 32 oz (Part # 131-3823)
The Toro Company · Primary source · Accessed August 31, 2026
The number requested, no redirect and no “Replaces Product” line. Internal designation 4-CYCLE FUEL, SNOW AND LAWN, 32OZ CAN. Toro describes it as “ethanol-free fuel formulated specifically for outdoor power equipment engines” with “no mixing required — pours straight in”. That settles what it is: fuel itself, not something added to fuel, which is why it is not filed beside the Premium Fuel Treatments in pt_fuel_additives. Recorded as a source with no part and no fitments while the category question is with the owner — the evidence is kept even though the record is not made.

Premium Fuel Treatment (12 oz.) (Part # 131-6572)
The Toro Company · Primary source · Accessed August 31, 2026
Toro’s own page for the number requested, with no redirect and no “Replaces Product” line in either direction. It describes what the treatment is for — protecting small 2-cycle and 4-cycle engines from ethanol-blended fuels — and names no machine, model or engine, so it establishes what the part is and nothing about what it fits. Every fitment for this number rests on the parts listings instead. **Re-read 31 August 2026 and unchanged.** Internal designation TORO PREMIUM FUEL TREATMENT 12 OZ BTL. It publishes no ratio: a bullet says to refer to the product label for the correct dosage for your fuel tank size, which is a pointer rather than a quantity.
