Depends what you are using it for but most engine manufacturers these days recommend at least 20% oil, straight castor, semi-synthetic or a mixture, you also need to decide how much if any Nitro content you wish to use (Nitro increases the power output of the engine) go to www.modeltechnics.com where you will find different Nitro fuels and their contents, I use Supaglow 10 for my ASP 46M engine

My experience of SiuperGlo is not good. Took out 4 conn rods in in 4 engines -  3 x SC, 1 x Irvine two years ago, so I reverted back to DuraGlo.
High castor is good but low synthetic if you feel the need to use a synthetic

I always used modeltechnics techpower fuel in my IC planes

looking at their website the Bekra fuel looks interesting, the no mess option sounds tempting

You need the higher oil content for better cooling in boat engines, funnily enough one of my mates had the same problem breaking conrods in his boat engine when using both duraglo and dynaglo, changed to supaglow and has had no problems since    Bekra not good for boats, designed for heli's. I've seen duraglow 16% destroy a  cmb67 hydro motor everytime it was run, needed a new piston, liner head button and bearings every time it was raced, not good   and a tad expensive

Hi Pilot 10,  theres a guy called Bernard Holder in Thornbury nr Bristol ,he,s been winning races in OMRA for years.in fact he holds most records of champion than anyone, he uses "Castor Straight" in all his engines I believe he gets it from Antics  Models .that says it all ..hope this helps ...good luck

You two Guys seem to have the same AVATAR.

Would you consider changing them as people are recognised by their Avatars.

We do have a thread on the subject if you could have a look please.

Bit like someone else is using "mine" and I did comment on that sometime ago.
For some reason or other my posts previous to the "BIG CRASH" were not linked back to me......


Scoop - my problems were with SUPERGLO an no other fuel. Back on DuraGlo and no recent on rod
problems  since the transfer back

[ids987]

The subject of fuel, and oil content always seems to be a bit contentious; whenever it comes up on any of the forums.
Speaking purely from personal experience (because it's all I can really speak from), I have run nothing but Duraglo 10 and Duraglo 16 in my .45 and larger engines (mostly CMB .45 and CMB .90), for 5 or 6 years now, and have not had any fuel / oil related breakages in that time. No bearing failures, and no cooked needle bearings. Prior to that, I used to run mostly O'Donnell or Byron "RTR" fuel (the race fuel has low oil content, RTR has more), but both are very expensive, and harder to get. I don't think the O'Donnell fuel is available over here any more. I still run Byron's 30 or 33% fuel in my .21s. One of those is RTR, the other is "Race"; can't remember which is which, but for the Race blend, I add, or have the model shop add castor @~200ml per US gallon. It was said, a couple of years back, that the "recipe" for EDL had been changed, and a number of people running Duraglo (and other fuels based on EDL), seemed to start suffering from bearing failures and needle roller / crankpin issues at that time. Not sure what happened from thereon in.

I could be wrong, but I think Bernard runs either GX5 or GN5. In terms of oil though, the principle is the same (as Castor Straight). I believe Castor Straight, GX5, and GN5 all have 20% Castor and no synthetic oil (if I remember rightly) - just that GN5 has 5% Nitro, and GX5 has some sort of nitro equivalent. Hard to go wrong with 20% Castor, and Bernard is a living example of "to finish first, first you have to finish".

Indeed an example to us all, Bernard took the BMPRS A, B & C class championships in his first full year of racing with us during 2012 , I don't think he runs with OMRA anymore though.

I have been using that avatar since joining Mayhem, I believe shawtingling has recently changed his to the same from something that was completly different, maybe he likes the look of the wavey flag better  Cheers Scoop 

[Tug-Kenny RIP]

It's still the same as a Moderator who joined in 2007.

Just trying to be reasonable and save confusion over recognition signatures.

Think you are right there Ian, supposed to be talking castor oil not sugar, mind u Mark looks as though he had more than a fair share tonight, I think someone may have been celebrating a Birthday    ..........maybe the castor oil will come in useful afterall
