How Much Do I Have To Premix In The Tank ?
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. |
idemitsu racing premix rotary fuel lube 1/2 oz. per 1 gallon of gasoline.

In that case he'd probably be ok going with 1 oz per gallon, it wouldn't hurt to add a bit more. |
I run 1 oz/gal (or 128:1) with Idemitsu pre-mix (no OMP)
only way to fly imo |

marvel i use just dump full bottle replace every two fill ups
|
that's primarily a detergent, not a pre-mix (or I wouldn't use it that way)

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

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

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...

or should i be premixing 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 :) |

Marshall 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. |

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

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 :) 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.
