Status: offline 		Hi everyone, I have a few questions about mixing my own fuel. I have a general idea about the ratio and what to use... etc, but I need some specific answers, I've just got into onroad nitro cars, so, sorry if I ask any stupid questions

I live in Sydney Australia, I own a Nitro TC3 with stock everything.

Now tell me if I'm wrong, ALL I NEED TO DO to mix my own fuel is to get some methanol, castor/synthtetic oil and some pure nitro and mix them in a ratio, am I right so far?

Does the ratio below sounds right for my car?

15% castor
5% synthetic
10% nitro
70% methanol

Hope I'm right so far. Now I need to ask all my fellow aussies in this forum, which brand and where I can get the above ingredients??
I suppose nitro can be bought from hobby shop, well thats what i've heard anyway.
But which oil is a good source of castor oil? I've heard ppl talking about Castrol M?? Does that comes like any other motor oil? Where can I get it in sydney??

What is a good source of synthetic oil? Where can I get them in sydney?

And finally, can I just buy any methanol?? I've heard that it is better to get aviation grade methanol? Is that true?

Thats all, sorry about the lengthy guestions, any help will be greatly appreciated

Status: offline 		Well I can't say for sure where to get the ingredients in Sydney but here in Adelaide we have a number of outlets for methanol and oil. Check to see if you have a Scotcher Petroleum depot there for methanol. Likewise, Caltex fuel depots (not the garage) have pure methanol (it's actually BP). Shell depots stock Shell A Racing fuel which has 3% acetone in it (a good thing) but you have to buy it in their 20 litre drums, no refills. So for methanol just look up fuel depots in the yellow pages and give a call first.

For Castrol M, my Caltex depot stocks it so I get both things at the one place. But I've also had the local auto parts place (Sprint Auto) get it in for me because they were Castrol dealers...no big deal, they just ordered it along with their next usual order. By the way, Castrol M is THE castor oil, it's the best. For synthetics you might have to get it from the hobby shop or if you know exactly what you want then maybe from a motorbike or gokart shop. I've never used it except for Mobil Jet Oil 2.

Likewise I don't use nitro at all...ever...but try a speed shop close to a drag strip. Someone else might be able to help you on that one.

That mix you mentioned should be fine, at least you've got plenty of oil in it.

Status: offline 		I'd give Aus-Torc Racing a call on 02 9821 1128 - they distribute methanol, nitro, synth (Klotz) & castor oil and the bloke I dealt with was very helpful. They can give you the location of the closest dealer to you in Sydney. I picked up a load from a mechanic in Paramatta - I think the connection was that they were heavily into drag racing.

Cost wise, I generally mix 15% Klotz KL200 oil with 3% castor and 10% nitro which works out at $4.70 a litre. 5% Nitro is about $4 a litre, 20% Nitro is $6.10.

Status: offline 		Sorry, I don't - I picked up a whole heap last October - a 200l drum of methanol, 24l of oil and 10l of nitro, but I've lost the address of the mechanic I picked it up from.

I should mention that buying the 200l drum got the methanol price down to $0.93 a litre, which is pretty damn cheap, but I'd arranged to split it with a few mates from the flying field. Buying a 20l drum would have meant $1.75 a litre.

If you call the dude at Aus-Torc I'm sure he'll sort you out with locations - I think he was trying to increase the number of outlets for his fuel & oil. I noticed he's got HStore (http://www.hstore.com.au/ProductSearchFuels.asp) selling his pre-mixed VP Racing fuels now, so that's not a bad option, it actually compares pretty well with mixing your own if you factor in the cost of the container.

But on the other hand, mixing your own allows you to brew different mixes to see how they perform with different engines, or to see what RPM increase you get for an extra 10% nitro etc.

Status: offline 		The stuff is called Coogee Methanol - I've got no idea what the grade is, or how that's defined, I don't think there's anything meaningful on the label, but I'll check next time I'm near it.

They'll probably even have affordably priced premix available for the terminally indolent or stupid. That, a place to drive and camaraderie notwithstanding, the extra benefit is the information & experience which will be made available to you. Well worth the price of a (usually subsidised) junior sub.

As for brew, not being a car engine person, ask the experienced club members. As a generalisation and from the little I've seen of R/C cars, cooling is more critical by the very nature of R/C car engines so that running the right plug and brew is important - especially where upping the nitro content is concerned.

The need for castor is now a myth served by folklore. You can use it if you want, but why would you when synth is as cheap, cleaner and a superior lubricant except in engines emanating from the same era as the folklore - ie: not contemporary car engines.

If you must have it, Castrol M can be obtained from the Castrol depot out in the western burbs. You can get either Methanol or Shell A, both now at exorbitant prices in 20 litre drums from either the Shell refinery just east of Parramatta or any Shell depot. Most clubs will supply methanol at ½ that price (empty drum exchange) and in lesser quantities if required. You don't need methanol certified for aviation use (water/meth injection).

A baseline brew of 5% nitro, 20% oil & 70% methanol will be safe until you know what you're doing.

You can mail-order ingredients, but the dangerous goods surcharges will kill you. You don't say where you live, but Castle Hill hobbies (north-west), Kellets (south-west), 'Greedy's' er I mean ..'Wing's n Things (Gladesville, Kingsford 'n northern/beach suburbs) or H-Strore (online) can guide and supply you with what you want.

Easist to obtain synthetics for modelling use are Coolpower or Klotz. Beware pricing. H-Store's pricing is about right.

Status: offline 		Thanx for the info sigrun, I think I'll get the shell A racing fuel.
I dont think I'll have the time to join a club, I'm only taking this nitro car thingy casually, perhaps in the future when I'm more serious about it, I'll find myself a club

Status: offline 		NP.

JFYI Shell A (used to comprise 3% Acetone, 97% Methanol, but now includes a minuscule volume of upper cylinder lubricant) works very well in our engines engine, you'll pay through the nose for it. It is no better for our purposes than straight methanol, athough it's coloured a cool purple and the drum it comes in certainly looks the part. I used to use Shell A just for the convenience many many years ago when it was sensibly priced. Last I enquired, Shell A is now just under $70- a drum (20 litre) from the depot! Shell methanol had also risen from a reasonable $27- to an absurd $$48-. BP also do methanol BTW.

Best of all, as I mentioned you can buy methanol through most clubs (and better hobby shops who treat it like bread and milk selling it affordably to keep you coming in and buying high margin sundries such as glow plugs etc), for around $26 to $30 for the same volume (20 litre drum). Shell A is simply not worth > twice the price of a drum of methanol. ie: $3.50 per litre versus $1.50 per litre. That $2 difference per litre pays for your 10% nitro. (Nitro averages around the $20 per litre).

Have fun!

Status: offline 		I haven't checked his prices lately, but a month or two ago the Aus-Torc racing guy was flogging 20l of Methanol for $35, and I think his nitro was $15 a litre. His Klotz oil was $14.30 a litre. Again, I'd ring him and check as things might have changed due to the exchange rate.

Status: offline 		I don't think you'll have much luck at the local servo - methanol & nitro are specific to a very small range of racing & model engines and oils, like castor, that are compatible with methanol won't work with petrol, and 2-stroke oil for petrol engines won't dissolve properly in methanol.

If you want to find out about BP and other manufacturers, call the distributor and ask to speak to their technical consultant - they'll tell you what's in their fuels, and who is likely to have it in stock around Sydney. In Canberra it's generally only the distributor that keeps the specialised fuels in stock, however in Sydney you might find specialist drag and motorcycle racing shops that stock methanol and related oils.
