TO MIX THE FUELSee Figure 3.? The product is powered by a 2-stroke engine and requires pre-mixing petrol with2-stroke oil. Pre-mix unleaded petrol and 2-stroke engine oil in a clean containerapproved for petrol.? The engine is certified to operate on unleaded petrol intended for automotive usewith an octane rating of 91 ([R+M]/2) or higher.? Do not use any type of pre-mixed petrol/oil from fuel service stations, such asthe pre-mixed petrol/oil intended for use in mopeds, motorcycles, etc. Do not useautomotive oil or 2-stroke outboard oil.? Use only synthetic 2-stroke oil.? Mix 2% of synthetic 2-stroke oil into the petrol. This is a 50:1 ratio

what machine is this for?? i doubt you put 4 stroke in with the petrol!! usually you mix 2 stroke oil with unleaded fuel at a ratio of 50-1
so 100ml of oil in 5 litres of fuel. If your trying to completely remove the striming head then usually they are a left hand thread, so turn it clockwise to undo it

The RG950 has a 2 cycle engine and requires both fuel and 2 cycle oil be premixed and then poured into fuel tank.

If you use straight unleaded fuel without mixing 2 cycle oil at the proper ratio it will ruin the engine.


• 2-Stroke air-cooled engine.
• Fuel and oil mixture of 50:1 (unleaded petrol: 2-stroke lubrication).

My recommendation for you is use an "all fuel" 2 cycle mix such as Opti or other that includes fuel stabilizer to reduce carburetor fouling.

The fuel mixture ratio for any 2 stroke engine on a trimmer in the last 5 years is 50:1 (air quality standards)
More than 5 years 40:1
10 years old = 32:1

Hi and welcome to FixYa, I am Kelly

First off the engine is designed to operate on unleaded fuel. The manufacturer makes no statements at all about E-10 Fuel. I will tell you from experience that you can use E-10 Fuel but.... should you ever have a warranty claim make sure the entire fuel system is 100% unleaded pre-mixed fuel. Your not going to hurt the unit using E-10 fuel as long as you maintain the proper fuel-oil mixtures. If anything a splash more of 2 stroke oil as in 22 mm / liter vs 20 mm. Or (+) 8 mm per gal.

I use 50:1 with Sthil 2-stroke oil in ALL my 2-stroke equipment. This ratio does not smoke at all, and does not foul plugs.

Never had a problem yet. At this mix ratio, you can also use it in 4-stroke engines, which means you only need 1 fuel can on site. Also eliminates the possibility of using the wrong can to fill the trimmer.

If it's not been started for that long, ensure that any remaining crud in the tank and fuel lines is cleaned out before even attempting to start it.

Put in a NEW plug, then mix up some 50:1 mix of unleaded and good synthetic 2-stroke oil (Sthil or similar). This will produce an almost smoke-free exhaust, and won't foul the plug.

If it does start, be prepared for LOTS of smoke initially, as all the old oil from inside the engine burns off.

A 4 stroke motor does NOT have Oil in the Fuel. There is NO fuel mixture. Just use regular gas. The only place you need oil is in the sump, and regular 20/30 motor oil will be fine.This only needs to be replaced when low on dipstick in crankcase.

FUELING ENGINE
WARNING: Remove fuel cap slowly
when refueling.
HELPFUL TIP
To obtain the correct oilmix
ratio, pour 3.2 ounces of
2--cycle synthetic oil into
one gallon of fresh gas.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline must be
mixed with a good quality synthetic 2-cycle
air-cooled engine oil designed to be mixed at a
ratio of 40:1. Poulan/Weed Eater brand
synthetic oil is recommended.Mix gasoline and
oil at a ratio of 40:1. A 40:1 ratio is obtained by
mixing 3.2 ounces (95ml) of oil with 1 gallon (4
liters) of unleaded gasoline. DO NOT USE
automotive oil or marine oil.

i guess your asking if its a 2 stroke or a 4 stroke right ?
2 stroke engines dont have an oil filler cap , just a fuel filling point, the fuel used in a 2 stroke is just normal unleaded (aus) but you mix 2 stroke oil in the fuel before filling (about 50/1) or whatever it recomends.
4 stroke uses the same fuel but you dont mix the oil with the fuel , it has its own filler point for oil , however you must use a 4 stroke oil with these .
hope this is what you were after.
