This is a simple way to help reduce carbon deposits inside your engines combustion chambers. If you wish to try a an approach a little more aggressive then we have had good success using Seafoam in an undiluted form injected directly in to the engine as a liquid. This this process there is a risk of engine damage as you would be introducing a liquid in to your engines combustion chambers. If you want more information on this service please get in contact.
The most fun stop ould come now. Simply take it for a few good hard drives this should help burn off some of the deposits left from the use of Synthetic oil. Lastly we have found that the addition to high quality 2T premix oil also commonly known as 2 Stroke oils suck as Idemitsu Racing Rotary Premix or Royal Purples HP-2C Premix to be highly successful at keeping general carbon buildup to a minimum.
Unfortunately some carbon deposits are inevitable in any engine but keeping things under control is the important thing. Put simply they are wrong, so as a trade off for those that feel they cannot justify such frequent oil changes, We would strongly advise that wou stick to an absolute maximum of miles or 6 months between oil changes, whatever comes first.
So why it is so important to have clean oil you ask? Well as with any engine the less debris, metal filings, and miscelanious crap you have suspended in your oil the better, this is just common sense. Your engine oil is there to prevent wear on surfaces in your engine that without the presence of a lubrication fluid would simple be a metal on metal contac, creating enormous amounts of wear and rediculous amounts of heat due to the friction.
Engine wear to some degree or another in any engine, even with the use of super high quality lubricants is unavoidable. While your engines oil filter does a great job it can only filter particles down to a certain size from the oil. Before oil gets to the filter it has to go through your oil pump, oil lines and oil cooler s where these harmful larger particles can cause wear to say the oil pump or in some partially block passages in the oil cooler s leading to higher oil temps and reduced engine cooling.
This means that to lubricate the many seals found in the engines rotors that make up the three combustion chambers of each rotor oil has to be injected in to the chamber.
This requirement is met by the use of a system specific to the Rotary engine. It consists in its most basic of terms of 3 major components. The OMP is supplied oil from the engines main oil pump under pressur, it is the job of the OMP to regulate oil flow to the engines oil injectors. The oil injectors are supplied via the oil feed lines. This is another of the reasons we strongly advise using premix in every tank of fuel, as an extra level of lubrication delivered to your engines combustion chamber independently of the the oil injection system.
For more information on premix and its advantages please take a look at our technical article on the subject of Premixing. Search for:. Home Technical Oil? Oil Viscocity Firstly let us cover the basic question. So to conclude this section, oils we would recommend Why Not Use 5w30? Please be very careful as hot engine oil is well hot and can burn. Warm up your engine then turn it off. Jack up your car. Another part is circulated on the shaft bearings and is used to cool the rotor.
Apex seal wear has been drastically reduced and engine life is longer. Mazda last built a production street car powered by a rotary engine in , the RX-8, but had to abandon it largely to poor fuel efficiency and emissions. It has continued to work on the technology, however, as it is one of the company's signature features. Here are a few of the common failure points on RX-8s, and how to prevent them.
Failed apex seals. Use dino non-synthetic oil only. Allow the engine to reach redline at least a few times a week. Allow the engine to warm up. Perform a compression test with some regularity. For the high risk groups RX-7's and the RX-8's , 4oz of premix per 10 gallons of gas is exactly what we recommend. Their factory injection rate is so low that you almost notice no oil consumption whatsoever. Less premix is required for this situation so 2oz per 10 gallons is just fine.
The sohn adapter cuts out the dirty engine oil and provides a new entry for clean fresh 2 stroke oil, which lubricates better and burns cleaner. Stick to a couple rules when choosing your oil. First, ensure its quality synthetic oil and secondly ensure that you use a 5w SAE rating or higher depending on your climate. Black Halo Racing recognizes that the Mazda manual calls for a 5w, non-synthetic, oil to be used in the RX8. Our research and testing as well as various engine rebuilds have shown these suggestions to not be enough to protect your rotary engine.
The reason is Black Halo Racing is not restricted by political or environmental regulations when making suggestions for your vehicle. Mazda, like any other automotive manufacturer, must create a vehicle with operates in all conditions, climates, and also falls within government regulations. The decision to use 5w is mainly environmental and fuel mileage driven. Thinner oils require the motor to work less hard during its operational process. The trade off is less protection of metal parts.
Unlike conventional oil, no two synthetic oils are created alike. There are various differences between synthetic oils and Mazda cannot fully endorse one brand over another. Finally, there is no data to show what the long term effects of injecting synthetic oil via the Oil Meter Pump would be.
It was easier for Mazda to suggest not using synthetic oil in the end. The RX8, like any other rotary car before it, requires that oil be injected into the rotor chamber to lubricate the various seals and rotor surfaces as part of the combustion process.
