Status: offline 		I know there is a forum for fuel but I wanted to ask a couple of questions here shince there are a lot more posts.

Q: Do you use synthetic only fuel in your ABC engines?


Q: If so, have you had any problems?

For those who might have answered no to the first question,,,
Q: Have you had any bad experience with the "Space Age" fuel?

Thanks,

Jimmy

I know you wanted to post here because there are more threads, but it is the old chicken and the egg thing. If you post over there then the thread count increases.

Anyway, have a read through some of the threads that are in the fuel forum. I think you will find that your question has been answered already.

I specifically asked a question about one type of fuel for 2-strokes, 4-stroked and heli engines and I know synthetic lubricants were mentioned there.

Also there are many other relevant threads.

Go have a read you might be surprised your answer is already there.

Status: offline 		Thanks for your reply Maverick!!!

To be honest,,,,,, I had not read all of the posts in the fuel forum.... I just looked at the titles,... I did not see one that I thought answered my question. After reading your reply, and sifting through the forum, I still would like to hear opinions about actual experience concerning synthetic vs castor. (Not what the engine manufacturers say you should do) (What has it done or not done for you?)Bottom line...
Has Using Synthetic fuel in you ABC engine ruined your engine???


This is what I am looking for.

respectfully,

Jim

I have heard of and seen a number of people using fuel with all synthetic lubricant in their 2-stroke engines and as long as they are not run extremely lean they seem to be OK.

Other people that are actually doing this may be able to chip in and provide a more substantiated response.

I have been using Powermaster 15% in my engines which is 18% lubricant of which 1/3 is castor. I have just purchased 2 gallons of Powermaster YS 20/20 which is 20% nitro and 20% all synthetic lubricant. I will be running this in 2-strokes, 4-strokes and a heli engine, after I finish my last gallon of 15%.

I do not run my engines extremely lean looking for every last ounce of power, so I believe I will be OK.

Anybody else care to chip in with real life experiences?

Status: offline 		Concidentally I fly with Maverick so he knows what I use in all my engines an that is Cool Power 15% Nitro to which I add 4 ounces of Klotz synthetic to each gallon which raises the lube content to approx 20% - all synthetic. I also know many who use Cool Power right out of the jug in 4 strokes, ABC, ABN and ringed engines with great success. Its all in the tuning - keep it properly rich and you should be ok. A bit of castor does offer addditional protection though since it withstands the heat a bit better than synthetics do.

Status: offline 		I fly alot of profiles and some 3D so throttle response and transition are my pet peeves. It been my experience that the European engines that I run (MVVS-Rossi-Moki) do not in any way shape or form like too much oil. It really messes up the midrange and overall needle settings. A long time ago Walter Morris told me to use a total of 17% oil with 1/5 of that being castor. I have to agree that it's all in the tuning. Some guys are needle tweakers and have to get the last stinkin rpm out of the engine. When the tank gets low or the needle is too lean, they're smokin It's my belief that if you need all those rpm's it's time to get a bigger engine or lighter plane. I rarely fly above 3/4 throttle for maneuvers anyway. I'd rather have the plane in front of me doing something than at the end of the runway setting up a turn so I can buzz by again. This is a visual game, isn't it? If you can diligently set and pay attention to your engine, the need for too much castor is also reduced. It will eventually gum up and otherwise bake a coating on your pride and joy. Not a big deal if you don't mind taking it down every season or so and clean the insides. Take Care_Bob

In answer to your question regarding the use of synthetic fuels in your ABC engines, If you want to avoid the hassel of mixing fuels and yet, obtain the best of both worlds, I strongly suggest "Byron Fuel".

It has both, synthetic and castor blend. I use their 10% nitro and 16% synthetic/castor mix in all my engines (2 and 4 strokes) without any problems whatsoever. It works wonders! It does cost a couple of bucks more but it is well worth it.

Good Luck to you,

Nestor

Jimmy - If you consider a fuel such as COOL POWER a Space Age fuel; the answer is No.

Sorry to say .... you probably toasted it running too lean.

Status: offline 		If your tank is placed correctly and you back off about 300 rpm from full power with the needle cool power works great.been using it for 2 years in my 91 and smaller engines without a problem and 2 of them are sceeming rossi engines that i use for hovering practice on ugly sticks.Its all in the tuning,to lean kills engines even if your using caster it just takes a minute longer.TECH TIP:If you have an engine thats wearing out use lower nitro fuel and it will pick up a little power but never use lower nitro in a good engine because it can damage it.

Status: offline 		wildthng...this seems to be the beginnings of another urban myth much the same as running an ABC rich will ruin it in a few minutes. If our ABC engines were so delicate then there wouldn't be too many of them still running.
