I am thinking about running premix in my 1988 Mazda rx7 10 AE . What are the advantages and disadvantages of it and what brand would you guys suggest to use? Another question is it what ratio is it?

i have a 93 rx7 and run the pettit racing premix. on the bottle is says to run 4 oz with a fill of 12 gal and for race 80:1 - 100:1 depending on severity of use. i run 12 oz for 20 gal and it works just fine. pettit has a video on youtube of how there premix burns cleaner than other brands. hope this helps

I converted my omp to run a 2-cycle tank through the OMP system. I have a tank with an adapter to feed the omp. I am using redline racing 2-cycle premix oil.

I also mix 4-5oz of oil per tank of gas (typically 16 gallons).

I chose the synthetic redline racing 2 cycle stuff because I have heard it can handle high heat, and it burns very clean.

Both of these are good attributes to have for burning in a rotary.

Currently using 10 oz of VP M2 to 3.5 gallons of E70. Plugs show no signs of oil burning. May try 12 oz per 3.5 gl soon.

I'm using the Klotz Benol racing castor oil for use with ethanol, methanol, and gasoline. I run:

1 oz per gallon when running 14 psi = 574 RWHP low boost setting
2 oz per gallon when running 23 psi = 810 RWHP mid boost setting

So far everything looks great, no oil on plugs (I run 11.5 NGK race plugs), going to run 2.5 oz per gallon of E85 for our next runs as we shoot for 1000 RWHP on E85 (and yes it's a 2-rotor)

No separation or gumming issues with this pre-mix.

I was running about 10-12oz per tank full in my 87 gxl. It ran the best on Shell Nautilus 2-cycle actually. Cheap and easy to find. But Klotz is the shiznit.

advantages to premixing would be a constant lubrication and no dry starts. Also, the smell is awesome and pisses off everyone behind you.

Whats the best premix in tank or premix with the re adaptor and oem oil injectors?

sleeper7

The VP stuff went up from 7 to 11 bucks for 16 oz. Just ordered some Klotz Benol off ebay. Tried it in the past but wanted to use something I could get local, reason for using the VP stuff.

Pre mix with gas. Lucas synthetic from your local parts store. Great stuff. Your HP is what determines how much premix. Stock, 1 oz per gl on gas. E85 needs more IMHO.

I've heard guys running 5 oz per gallon.

Currently running around 3 oz per gallon and will try 4 oz per gallon here soon. At 3 oz there is very little to no oil smoke out the exhaust. I would rather have a bit oil burning out the exhaust then the rotor housing wearing themselves to death. Seals are RA classics.

Yes but whats best to use
1.Ra adaptor for premix
2.premix in petrol?

sleeper7

Never used the RA adapter. Only benefit I see with the RA adapter is it injects clean oil but your still using the stock location on the rotor housing and the amount of oil. The stock oil location sucks IMO.

I like premix. Easy to adjust ratio accordingly to my driving habits.

sleeper7

Housing with RA classics. Drag car only but with lots of use. Had great compression, cold and hot starts easy.




Same housing after a quick "sanding" Still using the same used apex seals. Still has great compression, starts easy.

Nice!!! As I see it its all about tuner at the end... wish we had more off them here..
I know its not the best but I cant stand the fact every time I have to premix the petrol and if the car is in garage for 1 week the petrol and oil?? Isn't the petrol and premix separate after a long time in the tank??

sleeper7

About pre mix separating. If using the right premix with the fuel used, NO problems at all. Tested different oils with gas and E85 for weeks left on the shelf. No separation what so ever.

I tried non ethanol premix with ethanol. Took two days to separate.

i have been using amsoil 2 cycle for a while now. i mix about 1.5oz per gallon, running 13psi boost. car fires up good, clean burning. I am also running a stock metering pump so after a hard run it smokes for a few seconds to clear up then back to normal. I'd rather it smoke than not!!
i do prefer Klotz but cant find any in this backassward town.

So the ra adaptor is a no go? For 450hp?
I have to stay on premix or leave it for normal usevand track days use a bit of premix in the petrol?

how much premix should I put in my 10th AE 1988 rx7? Has a 16 gallon fuel tank.

I premix and use the adaptor.

I premix only 4-5oz per tank of gas with redline racing synthetic oil.

Hey mate, greetings from down under.
Are you saying you have e85 and two stroke oil mixing without separation? I did the same thing with our e85 (petrol/ethanol) and had clear separation. Can you share more details? You may have stumbled across something I can use. Cheers

sleeper7

WIth E85 you have to use a premix oil that is made for Methanol. Klotz Benol is good stuff. It will mix with any type of fuel.

You are running 3oz per gallon? That is a crap ton of oil. I run 5 oz per tank of fuel (16 gallons).

At the most I would run .5oz per gallon or 8oz 2-cycle oil to 16 gallons of fuel.

Are you running E85? good luck running .5 oz per gallon on e85.

sleeper7

Can you explain why 3 oz per gl is to much and why .5 oz is sufficient.
thanks

Sh*ts starting to get real.
