Hi there, I don't know if anyone will ever read this comment, but I have 2 questions for which I can't seem to find an answer : 1) Isn't the combustion affected by the addition of oil in the fuel system ? I'm conscious that 2-stroke oil is made for this use, but I wonder if the air-fuel ratio could be significantly affected, resulting in an incomplete combustion (the engine not being concieved this way). 2) I read (non verified information) that the insufficient amount of oil provided by the OMP system is due to emmission regulations. Do you believe that an OMP upgrade (stronger flow, bigger injectors) could improve the lubrication enough ? Thank you for reading me, and thanks for your work :) PS : I hope i'm readable, being a french speaker.
@sandervanderkammen92304 жыл бұрын
Your English sir is excellent. Very good questions. Mazda does not recommend premixing fuel with any type oil. Mixing oil with the air/ fuel mixture significantly reduces the fuels _Effective Octane Rating_ and increases the possibility of apex seal damage due to detonation/pre-ignition and erratic combustion. The primary failure mode of the apex and side seals is not lack of lubrication, but rather damage due to detonation and combustion efficiency problems. 2-stroke oils are specially formulated to be used in 2-stroke engines. All Wankel engines use the 4-stroke operating principle. Mazda only recommends 4stroke motor oil that's meets ASTM D-7079 For a maximum allowed ash/carbon deposits. No 2-stroke oils meet these minimum API specifications (API SL /EC-GF3) or higher. Mazda engineers have after very careful and exhaustive research and testing calibrated the OMP for maximum reliability. It is not recommended that anyone that is not qualified ever tamper with or remove/disable the OMP, this is garanteed recipe for premature engine failures due to seal damage. I hope that answers your questions

In 20 years, I have never seen a pre-S5 metering oil pump fail unless due to some physical trauma. Sure, the lines and injectors get old, and sometimes the pumps leak, both being easy fixes. It's a bit inaccurate to say that the stock metering oil system doesn't mix with the fuel. Indeed until the FD, it does. FCs have a set of oil injectors in the lower intake runners delivering oil to the air stream. Older carbureted rotarys supply oil directly to the carb. Premixing, in my opinion, supported by many years of observation, is a waste of time and money unless the vehicle is heavily modified or a track car. The stock metering oil system is reliable and nearly maintenance free. 1 oz per gallon is approximately twice the oil than delivered by the stock system. Way too much. Plus, for those of us who may store our cars during the winter, premix will separate from the fuel and build up over time.

Thank you so much. I've been wondering for a while, what if I got a Mazda Wankel, disabled/removed the stock oiling system, and just ran it on 2stroke premix, like Amsoil. No one answered me, until I found this video. Did no one answer me because I was asking mostly in 2stroke videos? Is it because wankels are rare, or is this some unspoken dark art? I was looking for lightweight engines with great power-to-weight ratios, for a motorcycle project. I was looking at gas-turbines, but I wanted to give Wankels & 2strokes another look, and plan around mixing oil at a gas-station, or have separate tanks, drain one premix tank, switch to another, go to a station when I have the opportunity, fill the empty tank with a certain amount of gas, then add a predetermined amount of 2stroke oil, that will mix in the tank, as I ride. Don't have to worry about cops, or other degenerates messing with me while I calculate & mix oil. Whether hooning at night, avoiding cops, or having to gas up at a shady station, I think my 2 tank idea with a switcher valve, is the best option, if I was going to rely on a 2stroke or Wankel. Again, thank you. Subscribed.

Since the Wankel engines are 4-stroke, and not requiring a premix has been pointed out as an advantage of reciprocating 4-stroke engines compared to their 2-stroke counterparts, I guess many people would either become confused about Wankel engines or simply reject them because they see premix as a burden that can be avoided with a more conventional engine.

First off, there are 5 different classes of synthetic base stock polymeric molecules used in motor oil, they all have different characteristics. Secondly, the API does not recognize any difference in mineral, synthetic or synthetic blends and considers the the word "synthetic" a completely meaningless marketing or advertising term. The API only recognizes 2 base stock classes based on lubricity performance, not formulation.

Mazda recommends 4-stroke motor oil with a API SL or EC-GF3 rating both which meet ASTM D-7097. This specifies Max. allowable ash deposits of 45 mg. 0.1% by Mass. The highest ashless 2-stroke oil ratings EXCEED this specification by at least 250%. This exactly why Mazda specifically requires 4-stroke oil not 2-stroke oils. Don't waste your time and money following bad advice that will only harm your engine. Follow the manufacturers specifications and ignore people who try to sell you a very overpriced, low quality Asian brand 2stroke oil because they claim it will save your apex seals.

You don't need to pre-mix. If your car is heavily modified and putting out a lot of power, then you will start to consider that. Pre-mixing means you get oil in proportion to fuel flow, so if you're coasting the injectors are closed, so you get no oil. Mazda looked at this early on in the development of the engine and they realized that. That's why they developed the oil metering pump because it puts oil in proportion to the load, not the fuel flow. If you're adamant about premixing, Mazda's early tests were done with 50:1 to 100:1 ratios of fuel to oil. more than that you're just wasting money and making more carbon.

look at "The Wankel Engine" by Jan P. Norbye and "The Wankel Rotary Engine" by John B. Hege. They both do a good job at explaining the history of rotary engines and premixing. Older vehicles did indeed premix (~1959), but that's before emissions became important. The rotary engine also uses oil because of the leakage past the seals. by 1965 the seal tolerances were getting better so the oil leakage past the seals was no longer sufficient to lubricate the housing. So the rotor had to be designed to feed oil to the apex seal for a "designed leak". During this time the oil consumption from the "designed leak" was roughly 500-1000 miles per quart. Based on that "designed leak" the ratio is roughly 100-200:1. which is basically 0.5oz per gallon. Mazda and other manufacturers didn't think it was acceptable for a modern engine to require the owner to mix oil in the gas or be able to accurately predict oil flow based on fuel flow. Additionally, emissions were becoming a big deal, it became important to reduce oil consumption to acceptable levels. So Mazda and other manufacturers came up with the metering pump used in the intake path. The oil is metered based on the operating conditions of vacuum and throttle position of the mechanical systems. For example when you are coasting your injectors are at 0% duty cycle and you have no fuel OR oil. By design the rotary does need oil to aid in sealing of the rotor tip. Don't get me wrong there. If your OMP is working properly then there isn't a real need to premix. Check out the procedure for testing your OMP in the FSM. With the engine warm disconnect two of the four OMP lines and and put the OMP lever to it's maximum position. Run the engine at 2000rpm for 5 minutes. you should collect roughly 0.2 oz of oil. This procedure simulates the engine and OMP being at redline for 5 minutes. The relation of oil per RPM is basically linear so near idle you can expect 0.02 oz of oil consumption in 5 minutes. Basically, the engine is premixing for you and doing a better job at it than putting it in the fuel. If you want more "peace of mind" do some basic maintenance and check that it's working. If you want more oil, enlarge the orifices on the pump. My opinion, just leave it stock and check that it's working.

I dont' own an rx-7 but I do have a question. I work in construction heavy equipment, then tamps, saws etc. Lots of the small stuff uses two stroke but we obviously pre mix it in a small gas can and use as needed. If you were to put it in the fuel tank. Would you put the amount of oil you're going to need in before fueling so that as the gas is being pumped in, it'd possibly be mixed more thoroughly or Well I don't really have any other ideas on it. But I am genuinely curious.
@N0SK1LLS7 жыл бұрын
I'm pretty sure either one works fine,two-stroke oil mixes really well with gas and the vibration from the enginge should do It's part too. I've never tried it but if you scale down the amounts,try pouring some gas in a plastic container and add a fiftieth(or whatever mixture you're running) of oil to see how it behaves! I'm kind a curious too whether it needs any mechanical influence to mix or if it does so by potentially released chemical energy!

I would recommend having a plastic tub in your trunk with a measuring cup, premix, and funnel. Fill up the premix before putting the gas in. Great time to pop the hood and check your engine oil level as well (would keep a qt of that in the tub as well).
@xblade65006 жыл бұрын
If anyone is wondering numbers. 128oz in a gallon of gas. Divide 128 by your ratio to find the amount of oil. So 1oz oil per gallon is 128:1 ratio. 100:1 ratio would be 1.28oz oil per gallon and 80:1 would be 1.6oz to the gallon. I don't run a OMP, so I use the 100:1 which comes to 6.4oz oil mixed into a 5 gallon gas can.

Premix? Seriously? Jesus, every large-displacement, high-quality and high-performance 2-stroke engine used in anything larger than a chainsaw and designed and built in the last 25 years or so has OIL INJECTION. But your Mazda rotary needs PREMIX? ROFLMAO. And you're using it at ratios that are way "old-school" even for 2-strokes. Many modern 2-strokes are running 50:1 ratios. You should mention the giant DRAWBACK with premix or excess oil in the combustion chamber for any reason. Oil is low-octane "fuel" and as you introduce increased amounts of it into a spark-ignition engine, you're increasing the chances of detonation, preignition, etc. And of course if you have an engine that's already worn or "leaky" or isn't "cleaned out" regularly by running it good and hard, oil in the "combustion chamber" is just BEGGING for carbon deposits. And carbon deposits that BREAK UP when the engine finally DOES get "cleaned out", are MURDER on soft surfaces like ALUMINUM ROTOR HOUSINGS. Nothing like putting a very effective and super-hard and abrasive grinding compound between your seals and housings.

Hello if anyone can help me with my rx7 please comment back. I'm having issues ..after I installed my freshly rebuilt turbo(bigger turbo s4 13b Mico tech) when I put it in I had to move some pump up(pollution pump I think) and it jammed a hard line which I'm pretty sure is the omp line. I never realized it jammed this hard line. It ran great no problems lots of boost I took it on a 4hr drive the next day and on my 4hr drive home the thing started running very speratic it literally died as I pulled in the driveway home. So what I'm asking is did I mess it up by jamming the omp line and taking it for a long drive??? Any help would be greatly appreciated
@MJTAUTOMOTIVE7 жыл бұрын
Cody Neef Hi Cody, Does the line(or hose) you pinched have oil in it. The oil metering pump is under the lower radiator hose on the front cover ,just follow the lines up from there and see if it is any of the one's you pinched. So to start with pull the spark plugs out. Then take of the intake pipe from the throttle body. With the throttle blades open squirt some engine oil down the intake from a lever type oil can. Pull out your fuel pump fuse and disable the coil packs. Crank over by hand first and if it feels OK use the starter for a good 10-15 seconds. put some more oil in the intake and repeat. When winding the engine over you should hear 3 good pulses from each rotor housing. If you have a compression gauge give it a compression test. (if you don't have a rotary engine specific compression gauge)take the schrader valve out of a standard one and watch the needle movement. If it is even across all 3 pulses refit spark plugs ,replace fuel pump fuse and put some premix in it straight away. Now try to start the engine. This will let you know if you have done any damage. I hope it's all good mate. Let me know how you get on with it. Cheers Mark....
@codyneef69827 жыл бұрын
Mark Thomas Thanks for the reply. I ended up doing some research and figured out it was a omp rod that I jammed in the "up" position. which I was told actually adds more oil. I did a compression test and indeed the rear rotor had a weak pulse. too much drifting and racing oh well.
