RMX,,,,which 2 stroke oil ?

[terryjhaynesMember]

Just read through all the threds in the teck section and didn’t realy see anything on what’s a good oil to run in yu smoker, in my cass an RMX. The bike shops in my aria recomend the Motul oils. I’m running “Motul 100 2T” and before that I ran the more expensive one like $24. a ltr which I think is a bit much.It’s not like I’m racing or anything, but I do like the thing to run well,and it can suck through the fuel too as specialy if yu stay on it a bit.I’m mixing 33 to 1 and get a lot of oil out of the pipe and on my rear disc which realy p#sses me of.
Any suggestions?
Cheers Teza.

I run my 08 300 on Motorex 2T at 50:1. I used ta run my old 300 on Motul at 40:1. Every now and than I’ve had to put mineral oil in on a ride. Just the lawnmower stuff from the servo and I could’nt really tell the difference. It was only for a short time though. Maybe check out a bike shop for some advice mate

I have an RMX among several other 2 strokes. I have been using Caltex Havoline which is a semi synthetic at 40:1 with good results. I usually fill up with the 4c a litre discount (presently 8c) and when you spend $2 or more in the shop you get another 2cents a litre off your fuel bill :laugh: 1 litre of 2t is about $12 so pretty good Another really good oil is Mobil fully synthetic about $60 from a distributor mix that at 50:1

once you get a good result try and stick to it,ie same oil/same ratio makes jetting your bike a lot easier.also a bit of a difference in ratio’s aint going to hurt it to much

Alot of those brand named oils are made by bigger companies like Mobil and Shell.

Having a talk to my uncle (who is now rertired but was the CEO of Mobil Oil asia pacific reogion)
about 2 stroke oils and what to run in my bike.
It becomes clear there is a balance between economics and quality.

Were not going to put good expensive oil in our lawn mower so mower oil is cheaply made so cheap to buy.
Outboard oil which is the best quality oil and a bit expensive,
why is this is because if your outboard fouls a plug you can die, if your mower fouls a plug the mower stops and no big deal really.

Alot of 2 stroke oils have additives,
additive to make smoke so the owner can see the smoke and know the engine is getting oil.
Additive to make it smell nice too and so on.

Companies like Motul, Motrex and smaller companies than the likes of Mobil and Shell,
these smaller companies approuch the larger companies to make there oil blends for them.

Back in the day when i was talking to my uncle Mobil made oil blends for,
Kenndell, Castrol to name a couple.

If it was me and i was using a 2 stroke i would go to a Mobil distributor and buy my oils from there,
i do that with my 4 stroke.
It is half the cost than buying through a shop and it is better oils than the Motul oils.
If i were using a 2 stroke i would just use outboard oils, 50:1 a water cooled outboard ratio is.

IMHO

mmm not to sure about using outboard oil on a regular basis in the dirt bike :unsure: only because an outboard has a constant flow of cooling water(sea,river lake ect)and will run at a cooler temp. I actually rang up the tech advise hotline (castrol from memory and he didnt think it would be a good idea) which is a bummer because I can get 2 stroke outboard at a really good price

your other points are spot on tho

OK just been out for a bit of a rap on the RMX with the fuel mixed at 40 to 1,much better result not as much oil out of the pipe. I’d still like to use a better oil and mix 50 to 1 I think,I will definitely be looking to buy oil at least 4,5 ltr at a time as I do with the boat oil.
What is the go with Mobil? I hear that 7 11 are taking over all their servo’s,so what will be the go with other Mobil products?

[DeanMember]

Tez, you need to get onto a local distributor for your 4 litre bottles of oil I dont think even the servo’s sell it in that quantity and you can bet not at $60

Not trying to tell you what to do Ollie.

Outboards do have a thermostat so the water flow is regulated due to it’s temperature,
so the engine stays at running temperature even if it sucking in fresh cool water.

I am not sure 100% but i think in outboards the water first flows near the exhaust and is heated that way them it flows through the engine.

All outboard oil is, is a good quality 2 stroke oil.
I ran it in my air cooled bikes for years,
pulled the engine apartto freshen them up,
no carbon deposits in the combustion chamber at all.

Not sure about outboards but thats definitely what happens in inboards. I’d be surprised if there wasn’t some form of pre warming though as without it it is very hard to keep the engine anywhere near operating temperature. Whatever is down the engine temperature would be controlled at around normal temps.

[DeanMember]

yep you are correct The incoming water does flow around the exhaust prior to entering the head and barrel.There is a thermostat as well,but the temp is no where near as hot as what a dirt bike temp gets up to.you can put your hand in the water tell tale and it wont burn you.But because of the extra cost why would you use it anyway? ie $12 a litre for the Havoline semi synthetic cheap as chips :laugh:
as mentioned before I wouldnt have an issue using the marine stuff if I had to.
some thing worth thinking about anyway.
