I have been running my G45 on chain saw oil, 32:1 for years and a friend has given me a bottle of Amsoil synthetic, for blending 100:1. I am a bit nervous to make the switch and would like to hear from others on their experiences.

I would be using the synthetic mixture for my BME 44 also.

Any comments appreciated.

Been using it for years in all my big 3-w's at 80 to 1. No issues at all. Sent a 5yr old engine to Bobby for a check up and he told me it was very clean inside. dennis

Run it if you like. You'll gain a little margin for error (in needle setting) if you mix a bit richer than 100:1.

I don't see much reason to run any oil leaner than 50:1, but that's just my comfort level. Oil's cheaper than engines. Oil debates are endless, almost religeous. You will get as many opinions as people offering them.

For my money, 32:1 conventional 2 stroke oils of good quality are a decent choice. But whatever floats your boat.

I'm with 'J' on this one, as though I've heard several folks extol the virtures of using that particular brand oil at a 100:1 ratio, using that lean a mix just does not sit well with me.

I've read enough documented stuff which advises against it to satisfy me, plus my engines run very well on the 50:1 synthetic mix that I use and which generates very little exhaust goo.

You have been running an engine for years without problems and you want to screw with it now?????[X(]

A more profound statement has rarely been made.

I have to agree with you guys. I took me a while to get used to 80:1. Started with Saber at 50:1 and slowly went to 80:1. But after hearing what the engine looked like inside after 5yrs. I don't worry anymore. when it comes to oil the real big thing is to mix the gas based on the oil at hand. If it says 50:1 don't add a little more or less. All of them work if mixed the right way. At 80:1 I have very little clean up and I'm comfortable doing this. I believe this is one topic that has no right answer. I was just answering stunt-mans question. Dennis

I have been running Amsoil 100:1. No long term problems yet. Very clean internals also. No signs of wear either. The bearings are spinning like new still.

Ha Ha, Kinda what I was thinking.

Unfortunately there's rarely but one reason to use 100-1 ratios in r/c applications, and that's reducing the intervals between belly clean ups. That's a very poor reason to run lean ratios. I'm unaware of any other benefit. Cost reductions are too small to have any real value. The engine can't benefit at all.

Amen.

Man's got a point. A dang good one at that. Why try to fix what ain't broke?

Stunt-Man,

Have you tried the AMS-Oil 100:1 in your Zenoah? I would like to know the results if you do.

Thanks,
Phillip

I have a Zenoah G26 (magneto version) running Amsoil Sabre Pro 100:1 and the engine runs very well.

I broke in the engine following Zenoah’s recommendations and then switched to Amsoil Sabre Pro I’ve been running this ratio for over 7 months now (including our Canadian winter) or 3.5 gallons of gas.
Two days ago I removed the engine from the airplane to perform a regular check up and it looks very good with no signs of excessive wear or build ups.

When I switched to Amsoil 100:1 ratio I noticed a slight increase on the RPM

The G26 is spinning a wooden prop 16x8 at 8,400 rpm.

Thanks,

Mario

Mario,

It's been a hassle lugging two different types of fuel to the field. Thank you for your quick response!

Hi guys I'm new to this forum but not new to this question.

I ran a portable saw mill for years and had a dozen chainsaws to go with it.

I tryed the 100 to 1 stuff and it works.
In my largest saw, a Stihl 088 it ran good at 100 to 1 and better at 75 to 1.
It just made more power. I have always assumed it was a better ring seal.

Scott Ellingson at Brillelli Modle Aircraft Engines will not warrenty an engine ran on Amsoil.
He claims it leaves very hard deposits and it has been the demise of a few of his engines.

He recommends the penzoil 2-cycle air cooled oil for break ins and Mogul air cooled synthetic after break in.

I believe Stihl and Echo make good oil for their saws.
An airplane engine doesn't see the kind of work their chainsaws do, so their oil should be good enough.
Plus they are making their own synthetic oils now.

The problem isn't finding a great 2 strike oil. 90% of them out there are a great oil.

There is something to be said about switching to a synthetic oil after running a petrolem baised oil.
If your new oil won't mix with a petrolem base oil then you should not use it in an engine that has ran petrolem base oil.
You can develope spots in the engine that are not being lubracated because the two oils won't mix.

Just my 2 cents ...
