Grade 87 fuel with NO ETHANOL. Ethanol will eat up the gas lines and gum your carburetor up over time.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

A minimum 87 octane containing up to 10% ethanol is recommended.
We recommend the use of 84-90 octane unleaded gasoline with less than 10% alcohol content. IMPORTANT! Use of fuel that has more than 10% ethanol content, such as E15 (15% alcohol), is NOT recommended.
All Briggs & Stratton engines can use up to, and including, 10% ethanol petrol. Always use clean, fresh, unleaded petrol with an octane rating of at least 77 for side-valve engines or at least 85 for overhead-valve engines.
Sure, you won`t hurt your lawn mower or string trimmer by putting in Premium gasoline, but you`ll be wasting your money since it`s more expensive. Contrary to popular belief, Premium gas does not improve fuel efficiency or performance in motors that don`t require it.
A minimum of 87 octane/87 AKI (91 RON); If operating at high altitude, see below. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable.
The easiest way to tell a 2-cycle engine from a 4-cycle engine is the number of fuel tank and/or oil sump fill ports. A 2-cycle engine has one fill port with a cap that has fuel pump and oil can icon. The cap will usually state the oil to fuel mix ratio.
Fuel for your lawn mower or outdoor power equipment must meet these requirements: Clean, fresh, unleaded. A minimum of 87 octane/87 AKI (91 RON); If operating at high altitude, see below. Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable.
Regular gas with 87 octane level is suitable for most engines, while premium gas with higher octane levels (91-94) is required for some high-output engines. Engines designed for regular-octane gas gain little to no benefit from using high-octane fuel.
Yes! We have modified our engine oil recommendations to state that you may now use a synthetic 5W30 or 15W50 oil in all temperature ranges. We recommend the use of Briggs & Stratton Synthetic Oil.
Any octane of gas available at your local gas station should work fine in your lawnmower, as long as you avoid the diesel section. High octanes won`t necessarily improve your lawnmower`s performance, but they won`t hurt the engine.
The AA recommends that, unless you are driving a turbo or supercharged engine, you should opt for 93. What is important to keep in mind is that 95 is more expensive than 93.
Lawnmowers and other garden machinery can run on either unleaded petrol or diesel. Most standard lawnmowers and garden machinery use petrol, while diesel is usually used only for commercial or heavy-duty professional-use machines, such as ride-on tractor lawnmowers.
If you put lower-octane fuel into your high-octane vehicle, whether by mistake or to save money on gas, you`ll probably notice the effects right away: things like poor fuel economy, reduced acceleration, and spark knock, which sounds like a high-pitched pinging or rattling noise.
If the octane rating is less than 91, you could damage the engine and may void your vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.” Note that this applies only to engines that require premium gas.
Regular gas is rated at 87 octane in most states, while premium gas is often rated higher at 91 or 93. Fuel with a higher octane rating can stand up to higher compression before it detonates. Essentially, the higher the octane rating, the lower the likelihood that detonation happens at the wrong time.
Husqvarna two stroke engines are designed to run on clean, fresh, unleaded petrol.
Two-stroke (or 2-cycle) engines require a mixture of fuel and oil be added to the fuel tank. This mixture results in both engine combustion and lubrication. Operating a 2-Stroke engine on gasoline alone will result in engine failure.
When it comes to fuel, your best bet for a small engine is gasoline with an 89 octane rating.
For most lawn mowers, fresh unleaded gas works just fine. You can buy a 5-gallon gas can (around $20), then fill it right at the gas pump. The octane rating should be 87 or higher. If regular unleaded gas in your area is below 87, opt for premium gas.
To minimize issues, you should use either ethanol-free gas in your lawn mower or fuel that has the least amount of ethanol content possible. Fuel sold at a gas station is often E-10 gas, which contains 10% ethanol and can be used for your outdoor power equipment.
The same fuel you put in your car isn`t always safe for your lawn mower, generator and other outdoor equipment. Using gasoline with more than 10 percent ethanol may be cheaper, but it can permanently damage small engine components.
The primary consideration is whether your car requires premium gasoline. If it does, you should use 87-octane only in an emergency. Otherwise, you risk hurting your engine. If your vehicle doesn`t require premium gasoline, 89-octane will work just fine.
Yes, drivers can mix the two types of fuel. The combined gas types will result in an octane level somewhere in the middle — something the vehicle “will survive,” according to The Drive.
The short answer is yes, you can use 20w50 oil in a lawnmower but results may vary.

What type of oil does it use? – Troy-Bilt 4-Cycle Curve Shaft Gas String Trimmer #41ADT41C966
ANSWER : I think all of these 4-stroke trimmers use SAE 30HD oil. I recommend synthetic. If you use synthetic, you can get away with using a multi-viscosity like 10W-30 if you can’t find straight SAE30 synthetic, but don’t use muti-viscosity conventional oil in these machines.
