3W advice
 

Hello, I just purchased a used 3W 60 engine. The previous owner says he ran 25-30 gallons thru it.

I was wonder what gas to oil ratio you current 3W owners are running and what oil you are using.

Any 3W 60's out there?

thanks,

40:1 lawn-boy in my 3w42i. I use 92 octane fuel & get a couple hundred more rpm vs 87 octane. Will eventually switch to amsoil synthetic.

I use Bel Ray MC1 @ 50:1 in my 3Ws.

For that matter, the same in my Brisons, DAs and so on ;)

Hi,

Any good oil at 40-50:1. Pennzoil aircooled works well. Amsoil tends to form hard brown carbon.

I have a 3W-60K, it is actually 57cc and has no reeds. It is the 3W equal to the zenoah G-62 with OEM electronic ignition.

Does your engine look like this?

I will know what it looks like in a week, I do not have it yet, it's in shipping.

Are there different versions of the 3W 60?

rcdude7 - what do you use with your engine?

Go with RCBugman's advice. He flys lots of 3w engines.

On my piped 3W-106CS I run BelRay H1R @ 32:1 NO issues whatsoever...

I have used penzoil aircooled and it works very well. I have also used the mobil 1 synthetic two-cycle oil.

Elson (bugman) is the 3W guy here, he operates a fleet of 3W engines on research planes and has many more hours on these beasts than anyone else. His advice is solid:D

Yes there are two 3W-60's. The one I have shown is long out of production. The later version is a rear carb with reed block configuration. It is more powerful and heavier, also larger in size than the "K" model.

The 60K was my first 3W engine, ran that thing forever! They really come alive with either a pipe or a can, and it likes a 22-10 Menz prop. Ran mine at 50:1 with different types of synthetic oils, all worked great. I liked it so much I bought another one!!
