I've looked around the net and forums reading about what oils to use in my new DLE 20 and have read that some oils are ok and some oils are not. I do know about 2 stroke engines and the importance of proper oil mix and type (oil for air cooled, oil for liquid cooled, oil for larger cc, exs.). I see that a lot of people use air cooled Pennzoil, but I don't see any around my area at this time. However I do own Echo equipment and use 'Echo Power Blend X' oil in them. It's an aircool 2 stroke synthetic blend oil. Can I safely use this oil for my DLE 20 at 32:1 mix?

Thanks.

YES

Yes.

Go to a Advanced Auto store....they have it or can get Penns for Air cooled engine use. Capt,n

I use echo oil for all of my planes, but I mix it at 50:1. I have a DLE 55 a DA 100 and a 3w106. I mix it 50:1. It works great and is readily available at home depot.

If you really want to know about oil, Google two stroke oil, less is more, by Gordon Jennings...I have been preaching this for many years...If you want to believe internet myths, at least read the WHOLE PDF article...Nuff said..
The dyno tests don't lie...[>:]

That is a good article. What I get out of it is that if you are using a non-castor additive, you need to stick to the manufactureres recommendations for mixing your oil.

I think you need to be careful with your summary. I am very familiar with the article in question.<div>Castor oil was used in the test because of its poor cleanliness properties and because of the tendency to still lubricate under extremely severe conditions. It is still not an oil that should be run through an engine in regular use. It was purely an oil that would deliver clear results under the shortened test conditions that Mr JEnnings required to illustrate a point : that less oil is not good for an engine.</div><div>
</div><div>I agree with him wholeheartedly. Stick to the engine manufacturers recommendation. If you have a multitude of engines, then mix your fuel for the engine with the lowest ratio requirements.</div><div>
</div><div>E.g. you have a DLE 20, (32:1), DLE 30 (40:1) DLE55 (50:1) and DLE110 (50:1) then running 32:1 in all the engines will not harm those those which call for a 50:1.</div>

I remember that article. Gordon Jennings was the God of Two Stroke Engines. Too bad he has left us.

Here are two interesting articles: http://www.ultralightnews.com/features/oiltest.htm, and, http://www.geistware.com/rcmodeling/...ngine_oils.htm. More up-to-date with contemporary oils used. FWIW.

Is this the link you were looking for?

I can not get Pennzoil "aircolled" locally. I may try the stuff linked below when I run out of oil. For now I am using some fancy, and expensive, synthetic. It works fine but spits a lot of oil out the exhaust. I see no real benefit from it.

IMHO it does not matter much what you use. Any "2-stroke" oil mixed at about 40:1 or more will do just fine. Guys seem to get in trouble by trying to see how oil poor a mixture they can run.

I would not run real castor oil. Been there and done that. It will gum up the rings. If you can, and don't mind, taking your engine apart to unstick the rings than castor is ok too.
