What oil should I get for pre-mix? I've searched and I'm not finding what I'm looking for. Just give a straight forward brand and weight and type and color and smell and edibility.

 

cheao and decent = walmart 2 stroke

 

keepin' it simple, thanks ice.

 

Marvel Mystery Oil.



KIDDING!

 

lmao, use this



Keep in mind its like 107$ for one ******* jug...

*EDIT* Nm, looks like your talking pre-mix, I just read the title and replied. Either way, now that his question is answered, lets talk about mazdaspeed oil and how its actually worth 107$ a jug?

 

anything that says TCW-3 on it

 

^ anyything except penzoil

 

use outboard 2 stroke oil... It smells better lol

 

mm...two stroke tastiness i love it! Seriously tho, buy the wal-mart stuff. I've experienced no problems

 

Walmart 2 stroke oil is great. The penzoil 2 stroke for some reason doesn't mix well and settles to the bottom of the fuel tank overnight resulting in lots of smoke first start of the day. No problem using cheap wally world oil.

 

WHAT THE HELL!!!! 107 a jug jeez thats insanity

 

You will mostly hear to use walmart oils here on the forum. Du to carbon build up I sugest you stay away from castrol based oils such as Blensol, however I love this oil if carbon is not a issue, such as a motor without power valves. TCW-3 oils will suspend mixed in gas longer so use them. I am a fan of good oils all around though pricy I recomend KLOTZ and Red Line, again I am a baliver in useing so called good oils. Argument sake it has been said / proven that useing a decent walmart oil works perfectly. Alot of performance 2 cycle oils have methinol in them and other octane boosters so read through them and ask around or search about there ash content. Methinol and Alcohal will help remove carbon from your motor. Give this thread a good read through and best of luck mixing your ride. https://www.rx7club.com/2nd-generation-specific-1986-1992-17/i-just-wanted-say-wow-premix-430787/

 

Come on! Read the label! It clearly says "WINNING OIL"....don't ya wanna win?

 

...sorry to steal the thread, but I figured this was the best thread to ask this in. Should N/A people use premix, too... or what? I work at Advance Auto, and my co-workers thought I was nuts for talking about premix for my engine. (They only know about rotaries because I talk about them all the time.)

Help me out here. Who should use it, how often, what's it for, other than extra lubrication, etc?

 

If your existing MOP is still working, then you would want to only use a very minimal amount if any (200 parts gas to 1 part of premix/2 stroke).

 

you use premix if you remove the MOP system. NA or turbo, makes no difference. If you still have the MOP, then you dont need it, except maybe in very small ratios for hard driving or track time.

 

Why do you need mixed oil for a rotary?

 

Pre-mix is where you disable the oil metering pump on the front cover of the block. Then pour oil into the gas tank as an alternate method of lubricating the engine. So a good mixing oil is necessary so it doesn't just fall to the bottom of the tank as well as clog the fuel injectors.

 

Rotary engine inject oil in to the combustion chamber to help lubricate the seals inside the engine. Since it is regular oil and not meant to burn, it can leave carbon deposits. Because of this, many people disable the OPM (which injects the oil) and premix to since 2-cycle oil is meant to burn. Also, people will sometimes just add a small amount for extra lubrication.

 

Alot of new comers seem to be asking about premix in this thread. Please review the archives and this thread https://www.rx7club.com/showthread.php?t=430787 , all of your queshtions will be awnserd.

 

I run premix in my stock engine that still has a functional OMP. I do it for the additional security. I have no smoke when I run and still pass emissions with flying colors.

As for methanol and other additives, I doubt any of the 2 stroke oil in regular stores (autozone, walmart etc..) have these additives. It would be easy to check the bottle label or MSDS to see if there is methanol in it.

Iceblue, I believe you are referring to castor based 2 stroke oils, not castrol oils. Castor is probably one of the best 2 stroke lubricants out there since it withstands temps better than any conventional or synthetic two stroke oil. Unfortunately, castor is not good in our situation because it leaves a varnish when it burns and this varnish can buildup and cause problems in our rotary engines. This light varnish is actually good for 2 stroke piston engines because it helps maintain compression. Castor also has a great advantage for kart racers because it easily mixes with methanol and nitromethane. A feature we don't need.

With that said, don't use Klotz Benol oil since it contains degummed castor oil. Castrol does make 2 stroke racing oils and as long as they don't contain castor, you'll be ok to use them. Personally, wally world 2 stroke is sufficent as long as it meets TCW III specs.

Side Note: Castrol A747 2 stroke oil contains castor oil in it.

 

This is what I use......I bought a case.

 

homebrewer - I am sorry if I was not clear on my post. Yes I was totally referring to castrol based oils such as Blensol gold label. Yes only the high dollar oils will consist of additives such as methanol, 2 stroke oil will lower octane, and this is why you should use a grade higher as well why they add things like octane boosters in the mixture.

That is very true homebrewer on the lubrications of leaving varnish but lubricating properly on a 2 stroke engine. This is why I do not recommend these style oils in our engines or an engine with a power valve. If you have a open exhaust port style 2 stroke engine like a go kart, this is very good oil for you. I run Blensol gold label and Red Line in my go karts when I raced shift karts excellent stuff. I use Klotz now in my dirt bikes because they run a power valve.

 

Iceblue, sorry I thought you misspelled Castor oil but you are correct many of the Castrol 2 stroke oils contain Castor oil.

I don't cart race but I do fly model airplanes and have fun with a 4x4 RC truck and homebrew my own glow fuel with methanol, nitromethane, and Klotz oils. The castor varnish that is left behind in the engine is great on protecting bearings from the corrosive effects of nitromethane and the water absorbing methanol.

In the late 80's and early 90's I was a little ignorant about oils and actually premixed with 10w-40 motor oil in the tank. I figured if it was good enough to be injected it was good enough to be added to the gas. I never had any carbon problems though but I don't recommend it when 2 stroke oil is available and cheap.

 

Klotz BeNOL Racing Oil - is used in a few of my friends fuel mixes iv used it in my t2 on race days for the added lubrication. i never seen varnish or anything on the internals that looked funny during rebuilds but i will defiantly let them know there has been problems with the oil leaving varnish.. one thing i can say about the stuff is that it smells good with race gas lol

i will give the blensol gold label a shot after the my motor been broken in..
