Hey guys,

I wanted to ask if any of you have tried Tornado fuel. I hear its recently beginning to get popular here in North America, but its been around in Europe and the rest of the world for some time now.

I recently picked up some 10% to break-in my GT2. I've never tried any other brand of fuel before and wanted to ask those who've tried it, what they thought of it compared to more popular North American fuels.

For me Tornado fuel is the best. I've been using it on my HPI Savage X engines (f4.1 and k4.6). I've experienced no problem whatsoever. Easy starting, smooth idling, fast acceleration, etc. By the way, Im using the 25%.

Hey! Another Filipino!

I really like Tornado. Everyone here is always using some America-made fuel. Just to be different, I took Tornado because I've read a bit about them and they're European! Easiest starting from any fuel I know. I'll be going to 25% soon, right after I finish this can of 10%!

Gotta love it, everyone has an opinion on who's fuel is best. In my 40+ yrs of glow engine experience I have found that the brand of engine and amount of nitro make far more difference in starting ease than who made the fuel. It also has a lot to do with having the proper voltage at the glow plug and a proper mixture in the combustion chamber when you flip it over. Most of my engines start first flip after proper priming. In all those years I have tried Fox, Cox, Morgan's, Byrons, Powermaster, Wildcat, Rich's Brew, Magnum, and others. Some I liked better than others for various reasons, but they all were very similar when it came to starting. I have owned Fox's, Cox's, Testor's, WinMac's, McCoy's, Veco's, Enya's, OS's, Thunder Tiger's, SuperTigre's, Rossi's, OPS's, Pico's, Magnum's, Royal's, ASP's, HP's, HB's, MDS's, MVVS's, Saito's, SK's, and probably others I have forgotten to name. Some started consistently easier than others and I won't name names but it didn't always have a lot to do with how much I spent on the engine. Some of the cheap ones started and ran very well. Come to think of it they lasted a long time too. In short, someone on this forum has a signature that states he has never met an engine he didn't like and I am very close to that belief myself since I have met very few eingines out of that long list above that I didn't like. IMHO, fly it like you stole it as often as you can get away with it, enjoy every minute of it because lifes too short to fret over the small stuff. Have a wonderful day gents.

As MVVS dealer, I have tested the smaller MVVS glow engines in order to find a synthetic oil fuel that would let them run well.
I got very inconsistent running on all but castor oil, which always restored good running within half a tankfull.
Drawback of castor is the gumming up, and slow carbon build inside the engine. At a certain amount of operation time, it also seems to form a nasty sticky layer between cylinder and piston, which needs to be removed to let the engine operate freely again.
As last fuel I then tested Tornado (1% nitro, 15% oil), I added 5% castor oil to get the oil to the prescribed 20%. The engines run excellent on this brew, keep needle settings well, and do not gum up. They also seem to run cooler as with pure castor, and accept wide needle settings.
A customer, who pointed me in the Tornado direction, does MVVS sprint tractor pulling races, and uses the tornado car mix (15% nitro, 10% oil) without any added castor. His engines look like new on inspection, and deliver excellent power. It must be noted here, that a sprint or car application is not the same as airplane operation.
Others have tested low oil content fuels (including me), and found the 10% oil content quite acceptable. I returned to 20% however. Not because of engine wear, but I like a nice, oily-feeling and slippery engine. On 10% oil, the engines felt a little dry.

Pe,

Good observations.

I know you tune your engines correctly, so do you think the castor build up occurred naturally just from running in the normal heat ranges? W8YE and I changed bearings in a 4 stroke that was run only on Omega with about 4 oz of castor added to the gallon. The engine was very clean looking inside without much of any evidence that it ran with castor. BTW, the bearings looked new but had failed. No signs of rust anywhere in the engine and only slight buildup on the piston head. The owner never used after run oil.

Didn't mean to hijack the thread here.....

Redisfaster, Excused the little " divertissement "
The castor build-up as described was observed in Supertigre engines. It was not a carbon deposit, but the engine(s) became sticky to the extend that running went erratic and full power was no longer there. Cleaning the piston and liner with solvent and steel wool/course paper brought back original power. The liner was cleaned with steel wool, which cannot be used on aluminum pistos. Paper has an extremely mild abrasive character that helps in cleaning off the castor plating.
Why this happened I do not know. We as final customers have no control over the castor quality, which will vary because it is a natural product. Maybe the oil I used was class A (second pressing) although it was quite pale.
It takes only microscopic scale corrosion for a bearing to fail. Four strokes lower ends get all the bypass sludge from the piston. For bearings, it's a hard life down there, even with added castor.

Red -

I've read a lot of positive comments regarding the Tornado fuels. Seems that one thing the Euro fuels have in their favor is the use of fairly advanced synthetic oil packages.....not typically found in US made fuels.

Being in Ontario, you'd do well to check into Cooper Fuels. Cooper is located in upstate NY (just across the lake from ON), and Brian is using perhaps the best synth oil package available in a US made fuel. I'm guessing, but I'd wager that Brian's oil is eerily similar to the EDL, Motul, and Aerosynt oils found in Europe. Fabulously good stuff. A world apart from the crap most people are pouring in a jug, and I'm a synthetic hater from WAY back!

It's worth shooting an email to Cooper Fuels. www.cooperfuels.com Brian sells an outstanding product, and he'd be happy to explain it all to you.

I'm sold on it.

Pe- Thanks for the info. Interesting. The retainer failed from all appearances. Lots of metal in the cylinder but no scratches or damage found.

RaceCity- thanks for the link.

Me too!

This stuff is like crack-cocaine. Once you (and your engines) have tried it you won't go back to running high percentages of old oils like Klotz or Morgans (Cool Power).
