Hi Everyone, Juan Here From Puerto Rico. I Have A 93 Rx-7 , I Tooked Of The Oil Metering Pump From My Engine .

I Like To Know How Many Ounces I Have To Pour To The Engine Everytime I Fill The Tank , And How Many Ounces I Have To Pour When I Take It To The Track ?

I'd recommend verifying this, but I believe you want a 100:1 ratio.

It all depends on how crazy you want to get with the math----I've heard guys run 2 ounces premix per gallon, which is about an 80:1 ratio.

There are 64 ounces in a gallon, you'd ideally want 1.5 ounces per gallon of fuel.

You'll be using quite a bit of premix......to keep costs down, you can get it by the gallon at Walmart in the boating/rv section. I forget the brand (yellow jug, maybe pennzoil?), but it's 2 stroke ashless synthetic.

bryant

idemitsu racing premix rotary fuel lube 1/2 oz. per 1 gallon of gasoline.
mazdatrix.

Eggie

No, it's 128 ounces per gallon.

Damn, you're right. That's what I get for going off memory.

In that case he'd probably be ok going with 1 oz per gallon, it wouldn't hurt to add a bit more.

KX500FD

I run 1 oz/gal (or 128:1) with Idemitsu pre-mix (no OMP)

only way to fly imo

KX500FD

I tried different types of Amsoil synthetic 2 stroke and fouled my plugs within a couple hundred miles...just fyi

SRGT-7

marvel i use just dump full bottle replace every two fill ups

KX500FD

that's primarily a detergent, not a pre-mix (or I wouldn't use it that way)

Yup, mmo is a cleaner, not a lube. If you're using it as premix without an omp, you're headed for trouble in my opinion.

Can someone please explain this mixture idea to me? I am new to FD's/rx-7s and didn't realise that you should mix your fuel with oil.

you can also use protek r from pettit specially designed for premix and wont foul your plugs

KX500FD

the rotary requires a small amount of oil in the gas to lubricate the apex and side seals, and the OMP is the factory "solution"; however, 4 stroke oil is not designed to burn, it leaves deposits, and it's a poor alternative imo

of course, Mazda is never going to sell a factory car where the owner is instructed to pre-mix the gas, they would be laughed at, because it's "inconvenient", "messy" etc....but that's exactly what you should do...or use a separate pump and reservoir to inject the proper oil, which in my opinion is Idemitsu rotary pre-mix

I am very familiar with dirtbikes as that is my other past time. So I can pretty much use the same mix for my car as I could use for my dirtbike except for mix ratios as my dirtbike would normally use 50:1 instead of a 90:1 or so.

I've been told by numerous high-profile rotary guys over the years that protek r is just your normal synthetic 2 stroke oil and is also vastly overpriced.

I have been using idemitsu premix (bought from www.rx7.com) for a while now.

KX500FD

but this isn't a two stroke

ever ridden an almighty KX500? if you haven't, you need to experience it

u should follow the containers ratio chart as I found that different brands require different amounts of premix. For instance: I use Castrol and it requires 1.3 oz per gal for 100:1 ratio. 100:1 is good for normal street driving. When I want to run her hard I go 50:1.

i thought you only premix if you remove the oil metering pump?.......is this not true
or should i be premixing

Marvel Mystery Oil is bullshit as far as pre-mix goes. That high priced, re-badged crap is probably bullshit too. Any good TCW-3 is fine...

You only need to pre-mix if you remove the pump (which requires an aftermarket ECU). Pre-mixing a moderate amount on top of the OMP is also commonly practiced as supplementary lubrication. The supposed benefits of doing this range from cleaner internals (despite 4 cycle oil being used too) to increased seal longevity.

I am not aware of any studies to prove this, but the aviation guys believe in using 2-cycle oils and they bet their lives on those engines. Good enough for me

A ratio is a ratio... a brand name does not change how many ounces are in a gallon.

128 ounces / 1.3 ounces = ~ 100 : 1

^no matter what brand it is

Perhaps you are under the impression that 1:100 is 1 ounce per gallon, as many people mistakenly say on this forum.

BLitzed33

Funny, I had the exact opposite in my case...Idemitsu fouled my plugs really quick and left some funny looking deposits on my plugs, I switched to AMSOIL saber professional premix and havent had any issues with fouled plugs.

I'm aware of this. What I'm just saying is to follow the ratio chart on the container for the brand's mixture ratio.

GOTBANNED?

Ive been told my Roger Manideville 16oz for a fill up. If it's good for Roger than it's good for me

vtakk eg

so how much should i use since i still have my OMP, also where to get it and what kind ?
and could i do it sometimes and not others, or if i start do i have to contine

thanks

Wow, I didn't realize there were so many variants of Amsoil 2-stroke oil. Are there any that are preferrable, or better yet, any that should be avoided for our use? I see an "HP Injector" one that is TCW-3, but the "Saber" one is JASO FD and a couple other things, and does not list TCW-3.
