Status: offline 		Sent an inquiry to both US Distributor for ELF and contact for Mexico (Paris) asking if they could advise if their product would mix with methanol and explained the reason for my question. I was hopeful that someone was familar with this ELF product. I have the oil for the gassers. The local chemical supplier would have to order a 60 liter plastic container just to allow me to get a test sample.

Will share reply from ELF.

Experimenting with an additional mix with methanol, oil and gasoline. See thread in Engine Conversions.

Folks,
This FAQ thread has not seen much activity in a couple months.

How about a few questions from some of our newer members or folks surfing through. Or, if you have a subject area (fuel related of course) that you would like a little further insight into, please feel free to ask.

As I mentioned in post #1, I will do my best to answer any an all of your questions with fact. I will contact other experts in the field to answer a question if necessary.

Thank you for visiting the forum.


Hi.

I have no experience of fuel since I had to mix my own diesel fuel in the 50s. Then it was 1/3 kerosene, 1/3 castor oil & 1/3 ether. The local pharmacist supplied this to me in glass stoppered bottles with the recommendation that I do not drop it.

I have recently. this week! bought a Zenoah G-38 and reading the manual found the recommendation that alcohol be avoided for fear of damaging the carburettor. It has a Walbro carb and I am under the impression that some gasoline contains alcohol. Weedeaters etc would seem to be in danger of damage from the alcohol in some fuels. I haven't checked on the local situation in UK. We certainly used to have Cleveland Discol (alcohol content) at the pumps.

The second thing that I have met is the corrosion and seizing problem due to glow fuel being left in Glow Motors. I have no idea what after run oil is, I now know how to use it but where do I find it in UK?

Any help would be appreciated.

I found some oil that indicated it was suitable for use in lubricating air driven tools . I found it at a local auto supply store. Also saw some Marvel Mystery Oil that would have work as well.
Merry Christmas

Thanks mikenlapaz

Air Tool lubricating oil sound a good move, I should be able to source that without difficulty. I would still like to know more about Marvel Mystery oil as a possible alternative. I years ago decided that re-inventing the wheel was wasting time in fact if I get lost in the car I am not above asking for directions.

I saw recommendations elsewhere that WD 40 never be used on model engines as after run oil and that it removed so much oil etc, that it promoted corrosion in the bearings.

After a number of people fell from unsecured doors on the main line trains and drunken behaviour was blamed, eventually it was admitted that revised maintenance schedules resulted in door-locks being lubricated with WD 40 which removed the grease and allowed corrosion. Quite a number of deaths appear to be as a result of not using the original system of greasing the locks and simply using the occasional spray of WD 40.

For any potential tourists etc to UK I think that now all the slam door coaches have been removed from service.

Thanks again, and a Merry Christmas to All our Readers!?!?

Status: offline 		Just use any air tool oil if you are not running a YS or other pumped engine that may have silicone parts inside (petroleum products swell the silicone). Marvel Mystery oil (not marvel air tool oil) will gum up if left to sit for a long time, it is best to stay away from that.

Status: offline 		If water contamination in the the fuel jug is a problem, then what about the water in the exhaust vapor that pressurizes the on-board fuel tank of the plane. How often do you recommend an on-board fuel tank be removed and flushed of water (droplets) or the water contaminated fuel in the tank that never gets sucked out by the clunk?

Status: offline 		The volume of water that could get into the tank through the muffler pressure line is minute and I doubt it could be measured outside of a laboratory. You can never have free drops of water in a tank if there's any methanol in it because it's totally soluble. Even if whatever remains in the tank after a flight has a very small % of water then by the time you've refilled with fresh fuel the % has dropped considerably. It's not an issue so don't worry about it.

Status: offline 		If mixing your own fuel and you want 20% oil in it do you go by weight or volume? Since the oil is about 25% heavier than the methanol it makes quite a difference. If you do 20% by volume you end up with nearly 25% by weight which is a lot. if you put in 16% by volume you end up with 20% by weight. Is that the correct way of measuring it? Before someone dives in with specific gravity stuff and gets all technical let me say that I just weighed a small volume of methanol on digital scales and it was 16gms. I then weighed an identical volume of oil and it was 20gms which is where I get these numbers from. The scales are only reading to the nearest gramme so it could be slightly out but you get my point.

Status: offline 		Fuelman: I bought a couple gallons of Powermaster YS 20/20 fuel for use in my Saito engines because I read on the internet that it was supposed to be the hot set up for Saitos, and it was on sale. Well, maybe it turns out it is too hot because I subsequently read that 100% syn is not recommended for Saitos. Maybe it's just a case of Ford vs Chevy. But here is my question:

How much Klotz Benol should I add to a full gallon of Powermaster YS 20/20 to "castor it up" so it is safer to use in my Saito engines?

Thanks!

Status: online 		OG, in the background you can see a red aerosol can that says Corrosion X on it, this is the best afterrun oil I've ever used. It is designed to protect metal in a sea salt environment. If an old engine has dried castor in it, the CX will soften it and render it harmless to the bearings. I have stored engines for 5 years or longer and when taken out of storage they look brand new inside.
