Frank: I've used a mixture of Lucas synthetic 2-cycle oil and castor oil with excellent results.

Frank,

Klotz is still available. They have a range of different oils. Check it out at:

     http://www.klotzlube.com/radio_control_.html

I am using both Benol in certain engines for the castor content and the original techniplate in ball-bearing engines with modern materials. Generally, I use a mix in the rest. I have ordered the  Benol by the case, direct.

As to your other enquiry, there are many, many opinions on oils, percentages, best mix of products, etc.  There is a really good article out there somewhere that I recall that discusses the nature of lubricants for model engines. I will see if I have it saved somewhere. By all means, read Randy's explanation of fuels.

I have heard folks use Motul in Europe. You can see "advertisements" on many racing cars for the brand. I don't think you are going to be able to "not discuss" brands, because most of the oil compounding companies are not going to tell you exactly what is in their oil, or how it was processed. In any event, they are all going to claim to have a unique additive package. Those additives may or may not help in our application.

I have doubts that using a synthetic crankcase oil designed for auto engines would be the most suitable for burning in a model engine. That said, I certainly never thought of doing so, have not looked up data sheets, have not tested it, and can't say it won't work. I'm sure you can get an engine to run using it, but what are the secondary considerations like wear rate, plug fouling or poisoning, etc.  Let us know if you try it!

      Hi All:

      What type of synthetic oil should I mix in my glow ruel? Today I looked at synthetic 2 cycle oils for motorcycles, outboards lawm equipment etc.  Will any or all of the synthetic two cycle oils suffice in our glow fuel mix?

      What a bout a full synthetic oil made for automobiles, trucks etc? 

     The cost of these oils vary from ok to OMG! Will they all work for our needs?

     In the past I used Klotz and it was fine but I do not know if it is still available.

    What about Amsoil synthetic?

                                                                                                                                        Tia,

                                                                                                                                        Frank McCune

Frank use  Klotz  it is  available  all over,  SIG   AMAZON  etc,  it is  not expensive  and you can buy it  as  all  synthetic   or  in 1/4 castor  ,  qts  or  gallons,

From Klotz oils, I find slightly better the HeliGlow #189. It has slightly lower viscosity which makes a noticeable diference in 4-2 shift and running symmetry. At least with ringed engines it’s better than their std synthetic. L
