Quick links. Premixing and cats Place for discussions about the RX Ideally, I would like to premix the street recommended 4mil of Idemitsu 2-stroke synthetic blend racing premix per litre of fuel when I pick up my R3 next weekend.

However, I would like to keep the cat. A lot of people are saying 2-stroke oil will clog the cat, ultimately leading to overheating and a potential source of engine failure. However, RX-8 cats of course fail without pre-mixing due to poor ignition.

And would a high flow cell cat like the one Racing Beat sell make any difference to the equation vs the OEM part? These mix ratios should also be good for the older generations of the rotary engine however you will need to use the mix ratios combined with your fuel tank capacity to work out your correct dose of 2T oil.

I am considering using Premix how often should I use it? Hopefully by now you should have enough information to decide if you feel premix is right for you. One of the questions we get asked is how often should it be used. Ideally every fill up, if you really want the benefits that premix can offer you and your rotary engine then yes you really want to be putting the correct amount in the tank every time you fill up, This is what we recommend.

Some ask if it is acceptable to use ever other tank of maybe every third tank. In reality some additional protection every other tank for example is better than none at all so by all means do this. But if you are looking at premixing on occasions and not on other as a way to save money on the additional price of a fill up at the fuel station then just remember a single bottle multiple tanks of fuel and when broken down the small additional cost for a shot of premix in your fuel normally works out at less than you would think.

Only you can decide if premix s right for you If you decide to start premixing then please only really consider high quality 2T 2 Cycle Synthetic Oil for your premixing application.

As Synthetic 2T is designed to burn leaving minimal deposits in the combustion chambers. It really is a false economy to go select your premix primarily on price grounds over quality. If you have any further questions about premixing, or you wish to start treating you engine to some of Royal Purples finest and want to know more then please get in touch and the Essex Rotary team will be glad to help.

This is not limited to the delivery of his solid mechanical skills but extends to the advice that he provides in relation to where your specific car is in its life, and what you have planned for it in the future. Rotaries operate like a two stroke engine. Every time a face approaches the spark plugs, combustion occurs.

Heat builds and remains in the parts easier in a rotary engine. To add to this challenge, the apex seal travels the longest distance of all the engine parts.

This whipping and wiping action causes wear issues and a propensity to chatter. Metallurgy and design helps to minimize the issue, but in the end lubrication of the surface is required.

Having a thin boundary layer of oil assists the seals in remaining viable for many years. From day one, Mazda has employed oil metering to automate the oil injection process. A small amount of oil is drawn from the oil sump and metered into the fuel and air stream to provide the sacrificial lubrication required. As years have progressed, Mazda has faced a continuing challenge of providing the needed lubrication while still meeting the United States and world emission regulations.

By altering the injection location, injector numbers, etc. There are some years of rotary cars that the injection profile was so stingy, that it easily becomes a wear issue for the engine. Unless the car is operated in a best practices method, the engine will wear itself out prematurely. In addition to this, there are operating scenarios that require more than what oil injection alone can provide. Welcome to the world of premixing.

Premixing is the addition of sacrificial lubricant to the fuel for the engine. Well that sure sounds antiseptic. What it is to the layman is adding oil to the gas to reduce wear.

What we need to explore is defining who needs to premix, how much to add, and what type oil. Who needs to premix falls into three categories. One is totally obvious, but requires mention: The person who has deleted the oil metering system.

There are those among us that desire a simpler under hood look, operate the car in strictly motorsports scenarios or have a system that had failed and deletion of the system was the approach taken.

In these cases, premixing is absolutely vital. Permanent and irreparable damage will occur if it is not adhered to with every tank full. For this reason alone, we do not recommend ever removing the oil metering system. It is nice to have a fallback for non-sporting operation of the car. Our next category is those that use their cars for occasional sporting uses.

These are otherwise street driven cars. These events commonly feature 20 minute continuous road racing. The additional loads and heat cause wear to occur at a greater rate. In cases like these, it is ideal to add a small amount of premix to the fuel to supplement the already existing metering system. Other risk groups include occasional drag racers, drifters, street grudge matchers shame on you , and cone bashing Auto Crossers.

A little premix will go a long ways to getting every mile possible. Our last category is the high risk cars where Mazda was particularly stingy on their oil metering. These cars are as follows:. If the determination is that you have to premix, the obvious question is how much to add? Turbo and non-turbo applications have different rates. Supplemental lubrication requires less than total premixing. Fuel types like gasoline require less than alcohol burners. Under ideal conditions, a typical street operated RX-7 or RX-8 will consume a quart of oil between 1, and 2, miles.
