Our acreage picks
STA-BIL Starting Fluid 11 oz 6-Pack for Gas and Diesel Engines
A 6-pack of 11 oz cans rated to -65°F with upper cylinder lubricant, listed for lawnmowers, tractors and snow blowers.
Read the full review
The STA-BIL 6-pack is the broadest listing here: it is rated to -65°F, contains an upper cylinder lubricant with corrosion inhibitors, and lists gasoline and diesel engines from cars and trucks to tractors, lawnmowers, snowmobiles and snow blowers. The listing also states it will not harm catalytic convertors or oxygen sensors.
Each can holds 11 fluid ounces and the pack holds 66 fluid ounces in total, with a pack weight of 4.3 pounds. The warranty field reads only Warranty, with no term stated, so it scores zero on warranty.
Pros
- Rated to -65°F for cold morning starts
- Upper cylinder lubricant and corrosion inhibitors included
- Listed for gasoline and diesel engines, including lawnmowers
- Will not harm catalytic convertors or oxygen sensors, per the listing
Cons
- No warranty term is stated; the listing only says Warranty
- The listing does not name a 2-cycle-only formula
- Spray form only; no pour option is stated
- Six cans take more shelf space than a single can
Johnsen's 6752 Starting Fluid 10.7 oz
A single 10.7 oz can with a 50% ether blend rated to -65°F, listed for lawn mowers, chain saws and outboard motors.
Read the full review
The Johnsen's 6752 is the single-can pick: a 10.7 oz can with a 50% ether blend, rated to -65°F, that the listing says helps start stubborn engines fast in cold weather and saves batteries. Its engine list covers passenger cars, diesel engines, lawn mowers, chain saws, outboard motors and fractional horse power engines.
The can weighs 7.2 ounces and the listing says to check with the manufacturer on warranty, so no warranty term is stated and it scores zero on warranty.
Pros
- 50% ether blend stated on the listing
- Rated to -65°F for cold weather starts
- Upper cylinder lubricant included
- Listed for lawn mowers, chain saws and outboard motors
Cons
- No warranty term is stated; the listing says check with manufacturer
- Single can only; no multi-pack is stated
- The listing does not name a 2-cycle-only formula
- Item form is listed as liquid, with no spray detail stated
Johnsen's 6762-12PK Starting Fluid 10.7 oz Pack of 12
A 12-pack of 10.7 oz cans rated to -65°F with upper cylinder lubricants for stubborn cold weather starts.
Read the full review
The Johnsen's 6762-12PK matches the 6752 on cold rating and lubricant, rated to -65°F with upper cylinder lubricants, but in a 12-pack of 10.7 oz cans in aluminum or steel. Its bullets repeat the same cold weather and battery saving claims as the single can.
One contradiction to note: the spec table lists Unit Count as 126 ounces while the title lists 10.7 oz per can in a pack of 12. Trust the title and bullets over the spec table, and treat the pack as twelve 10.7 oz cans. No warranty term is stated.
Pros
- Rated to -65°F for cold weather starts
- Upper cylinder lubricants included
- Pack of 12 cans for several engines
- Aluminum or steel can construction
Cons
- No warranty term is stated; the listing says check with manufacturer
- Spec table Unit Count of 126 ounces conflicts with 10.7 oz per can in a 12-pack
- The listing does not name a 2-cycle-only formula
- No applicator or straw detail is stated
Stens 752-942 Starting Fluid 11 oz for Outdoor Power Equipment
An 11 oz can listed for outdoor power equipment and effective to -65°F, as an OEM replacement for Gunk M3815.
Read the full review
The Stens 752-942 is the most directly yard-focused listing here: it is listed for outdoor power equipment, effective to -65°F, and sold as an OEM replacement that replaces Gunk M3815. The bullets give a package weight of 0.85 pounds and a flash point of -17.0 degrees Celsius.
The spec table names Gunk as manufacturer and lists liquid volume as 325 ml, while the title lists 11 oz; the title figure is the one to use. No warranty term is stated, so it scores zero on warranty.
Pros
- Effective to -65°F, per the title
- Listed for outdoor power equipment
- OEM replacement for Gunk M3815
- Flash point of -17.0 degrees Celsius stated
Cons
- No warranty term is stated; the warranty field reads only dots
- Spec table lists liquid volume as 325 ml while the title lists 11 oz
- Single can only; no multi-pack is stated
- The listing does not name a 2-cycle-only formula
CRC Starting Fluid with Lubricity 11 oz Pack of 12
A 12-pack of 11 oz cans of starting fluid with lubricity, with no cold rating stated on the listing.
Read the full review
The CRC 05671-12PK is the thinnest listing here: its title promises starting fluid with lubricity in a 12-pack of 11 oz cans, and the spec table adds a can container and high viscosity, but the bullets state no cold rating, no engine list beyond Automotive and no performance figures.
It still earns a place for buyers who want a 12-pack with lubricity and do not need a stated cold rating. No warranty term is stated, so it scores zero on warranty.
Pros
- Starting fluid with lubricity, per the title
- Pack of 12 cans of 11 fluid ounces
- Can container with high viscosity stated
- Listed for automotive use
Cons
- No cold weather rating is stated
- No engine list is stated beyond Automotive
- No warranty term is stated; the listing says contact manufacturer
- The bullets state no performance figures

Buying guide: choosing the best starting fluid for 2 cycle
Cold rating first
Four of the five state a -65°F rating: the STA-BIL 6-pack, both Johnsen’s cans and the Stens. The CRC 12-pack states no cold rating at all, so it suits only buyers who do not need a stated cold weather figure. If cold mornings are the problem, start from the four rated cans.
Lubricant in the can
Three listings state an upper cylinder lubricant: the STA-BIL, the Johnsen’s 6752 and the Johnsen’s 6762-12PK. The CRC states lubricity in its title, while the Stens states none. A lubricant claim is worth more when it names the part it protects, which is why the upper cylinder wording stands out.
Pack size and storage
The STA-BIL comes as a 6-pack, the Johnsen’s 6762-12PK and the CRC as 12-packs, and the Johnsen’s 6752 and the Stens as single cans. The STA-BIL pack weighs 4.3 pounds and the Stens package weighs 0.85 pounds, so a 12-pack needs real shelf space in the shed. See all mower maintenance gear we cover.
Engines the listings name
The STA-BIL listing names lawnmowers, tractors, snowmobiles and snow blowers; the Johnsen’s 6752 names lawn mowers, chain saws and outboard motors; the Stens is listed for outdoor power equipment. Match the can to the engines in the shed, and see our best starting fluid for lawn mower picks for a mower-only list.
Read the manual, keep children and pets out of the yard while you work, wear eye and hearing protection and sturdy footwear, and never exceed the slope rating of your machine. Refuel only with the engine off and cool. See CPSC lawn mower safety. Read our Safety Disclaimer.
Matching It to Your Property
- Keep a can where the trimmer and blower are stored, so a cold morning start does not wait on a trip to the store.
- Properties with several engines suit a 6-pack or 12-pack; a single trimmer suits a single can.
- The Stens can is listed for outdoor power equipment, which covers the trimmer and blower fleet.
- Store cans where they stay dry and out of the way of mowers and carts.
The Acre Score explained
The Acre Score weighs performance, build, value, safety and warranty. For starting fluid, performance means the stated cold rating and engine coverage, build means container and material, and value means pack size against what the listing states. No listing states a safety certification or a warranty term, so safety and warranty score zero across all five.
| Product | Acre Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| STA-BIL Starting Fluid | 9.5 | 32 | 20 | 21 | 0 | 0 |
| Johnsen’s 6752 | 9.5 | 30 | 20 | 20 | 0 | 0 |
| Johnsen’s 6762-12PK | 9.4 | 29 | 20 | 20 | 0 | 0 |
| Stens 752-942 | 9.4 | 30 | 19 | 19 | 0 | 0 |
| CRC 05671-12PK | 9.4 | 26 | 19 | 21 | 0 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
