Stihl Premium 2 stroke oil

[grasscutter]

I brought the Kinetix brand into the shop for the exact same reason. The Stens brand is a solid product too in my experience. I've had several customers come through with plugged exhaust screens. To a person they all were running Stihl oil. I didn't ask which flavor. I send them home with a free bottle of the Stens after repair.

It was probably the orange bottle.

When I took the exhaust screen off, the carbon was barely laying on top of the webbing of the screen. Not sticking at all.

I was able to easily dust off the screen with a toothbrush.

I like Kinetix bar oil. Haven't tried their 2 cycle oil. I wouldn't run Stihl oil if you gave it to me. Been running Saber for years @ 60:1, 2 cycle and 4-mix equipment.

No. It's average at best.

Yeah the stihl 2 stroke oil appears to leave carbon deposits behind in the cylinder.

I don't want to go through the trouble of adding a stabilizer. I want it built into the oil.

I am extremely particular with the mix ratio. If the price of fuel is $6.00 per gallon, I will buy $15 worth of fuel.

That way the pump shuts off at exactly 2.5 gallons.

The other thing I'm extremely particular with is fuel cleanliness.

I carry a paint brush in my car for dusting off both the string trimmer around its fuel cap and the gas can itself.

I don't want any microscopic particles of any kind falling into the string trimmer's tank or the gas can's interior.

I also make sure my arms and hands are dusted off before removing any of the fuel caps.

When the gas can is empty, I shine a flashlight down in there looking for particles.

If I see anything at all, I flush out the gas can with fresh fuel.

The neighbors are used to me standing out in the middle of street emptying gasoline onto the asphalt in broad daylight.

I pull oil samples and look at the under a microscope. Its fairly difficult to not outside contaminate gas and the oil used in saws and weedeaters. As soon as an oil container is opened it will start collecting dirt at the cap threads.
The bar and chain is full of dirt anyways so just keep the dirt levels below what will clog up the oil pickup.
They make fuel funnels with filters built into them.
There's no need to be dumping gas out in the street.

OK sorry gents, just to confirm, this isn't the same stuff as Stihl's biodegradable oil?

I'm going to start using the oil bought with the FS111, which says Premium and contains fuel stabilizer. These in the little 100ml generic white bottle, orange cap.

We might burn through the 5 litre Jerry in a few days, weeks or a month depending on how much the grass and weeds grow. I don't want to bother with garbage.

Any FD mixed 40:1.

Just use a fuel filter to pour your gas through, no need to waste it.

Have you ever seen filter funnels?
Cheese cloth works pretty good.
I've heard coffee filters do around 6 microns but im not sure how this was tested.

My neighbor gave me a craftsman filter many years ago. Works well.

Mixed up a batch. The 5L Jerry is actually around 4.7L and I underfill a bit when using these precise little 100ml containers. It has stabilizer already in it, which is great. I usually rinse the containers (I save and reuse them over the years) with stabilizer to snag the last amount of oil.

So, the Premium is made by Castrol, which was mentioned in those videos.
