Ayeeee I have the same one

Bad advice, pouring the wrong oil down the wrong filler hole is just monumentally stupid...

@Garden State NJ Good it had a clutch slave cyclinder fail but other than than no problems with it

Why would you recommend an oil that does not meet Mazda's minimum API/EC/JASO rating and is not rated for 4-stroke engines.

Never tamper with or remove the OMP... the Sohn is a waste of money and does nothing beneficial.

How did you tune your car? I’m interested in tuning mine for regular as well if it’s safe for the car (as in it doesn’t break my engine)

Daii Jesus I use VersaTune but there are a few different software brands you can use. Basically did a bunch of benchmark pulls, pulled back the timing, load and VE, and put a safer fuel map.. put regular in it and slowly started to increase while watching for knock. I’m currently at 38 degrees at 8k rpm with no knock whatsoever with regular 87 fuel. My engine is far from stock though, so I wouldn’t go as far as 38 degrees on a stock renny 😅

@@DanMarcelino So, exactly what mods did you do to achive 87 oct gas trouble free?

JDM Lover it’s mainly the tune.. but these mods allowed me to push the timing and load further.. Mine has been CNC ported on both the intake and exhaust ports to basically the largest ports you can have without going bridge or peripheral, rx7 treated apex seals, enlarged oil galleries, Fd oil regulator, cooling mods for both oil and coolant, 5.8 final drive and tuned by myself..

The final drive, intake and custom exhaust don’t really matter in this case but why not lol

unrealistic... almost completely carbon weighs about 860 kg. In Russia I raced this one in the time attack championship

Is the omp not those 2 holes? Where does the omp squirt oil from?

NO 2 stroke oil meets the minimum API, EC or JASO specification for the RX8 engine.

and troble with more carbon build, it isnt good for injection and etc carbon build in air intake :) i agree premix isnt good for rotary

so do you have a recommendation to deal with that? i feel like simple bearings with pressurised oil feed are tried and tested so i'm surprised to hear this

Time for an LS swap or just buy a real performance car.

Have 74,200 Miles original motor.

Do you still have a Cat? If so, it can break loose inside and rattle until warm.

but thanks for being brief, nice short informative video. ive seen videos on the same subject that are 30+ minutes and full of a bunch of filler.

which series of rx8 do u have?going to pick up a series 1 soon with 20k miles on it

Yea dont start now. You’ll likely kill it even sooner.

Don't waste your time, Wankel engines are much less efficient on gaseous fuels.

Itemitsu is not rated for 4-stroke automobile engines and does not meet Mazda's minimum API/EC/JASO rating..

Never, premixing is a monumentally stupid practice base entirely on false rumors and ignorance. Follow the your manufacturer's lubrication specifications and maintenance procedures and only use properly labeled (4-stroke, spark ignition) oil with the correct API 'S' rating.

Don you have to know that your injectors are working in the first place, but it can't hurt to premix small amounts < 1oz will help.

You should never premix or use 2-stroke engine oil.

No

Never premix

I have to disagree with you on that one chief yes the 3rd injector is beneficial mo doubt however the amount of oil in sprays isn’t adequate for long term driving so I recommend ore mixing regardless. And just as an added comment the rx8 also have the omp... so def premix if you want your engine to last you a while

Never use 2-stroke engine oil, there is no available 2-stroke oil that meets the minimum API specifications recommended by Mazda.

@@sandervanderkammen9230 false... www.idemitsulubricants.com/idemitsu/racing-oil/ I hope this helps... 😁 Despite what Mazda says as they're legally not able to say so because premixing is known to clog a catalyst system over time necessitating the cats replacement or removal which is illegal for the later in nearly every country. So it makes sense for them to say "No, we did the research and you don't need to do " x, y or z" EVERY vendor and racing organization will tell you without a doubt that it's necessary.

Overpriced scooter oil

Yes. Premixing is purely to add lubrication to the housings, for series 1 to compensate for the lack of lubrication in the center part.

Never premix...

It comes down to the basic thermodynamics of compressing volumes. The higher the compression ratio of the engine, the more the air/fuel heats up as it is compressed, and without a high octane level, predetonation can occur. These renesis engines are high compression, plus when you premix, you are lowering the effective octane level of the fuel, so it is super important to be using a high octane level fuel to prevent possible predetonation. As a turbo engine builder, I am assuming you are running lower compression ratio engines which except boost better. And as long as you have a proper intercooler set up with a low compression ratio engine, you probably don't need a higher octane, but that would really come down to experimental testing because everyone's set up is different. Either way, if you can afford a higher octane fuel, it makes sense to prevent predetonation and damage to your engines.

@@PeterArmour Did you not read my comment AT ALL? My comment clearly states the effect of Octane & Detonation so good job wasting your time on that reply. I want to know what all these other huge problem are NOT related to the obvious detonation that I covered in my initial comment.

@@repurposedperformance5762 My apologies. There is no effect other than detonation. But predetonation on renesis engines sends a jolt which can cause blowby, break off a piece of carbon build up in the exhaust port, or even break an apex seal (the smaller apex seals on the renesis engines are much more prone to breaking than the larger ones on the 13brews). Not sure exactly how piston engines are affected by detonation in comparison, but rotary engines, especially the renesis engine are very much affected by predetonation.

fr BUT should ping or detonation EVER occur on a Rotary it can cause engine damage they HATE it

Do not tamper with the OMP and never premix. Premixing is monumentally stupid

@@sandervanderkammen9230 apparently it's helping a few owners I know of who have Series 1 motors that have gone past 100k with no issues, and good compression. They swear by it. I believe they said it was to assure coverage of the central part of the apex seal that the original dual oil injectors missed and they disconnected the injector system of the Renesis. I don't know what % formula. Back in the early eighties when I had R100s, I made one reliably run well past 100K miles, and part of the reason was oil injector parts for 10A's were rare. So we local R100 guys premixed, calculated using the new tolerance of 1500 miles per quart calculated against overall average mpg of 19mpg. We'd put 1/2oz per gallon of Castrol GT 10w40, 10 gallons...5 oz., etc, etc. No issues, don't remember having wet plug issues or hard starts... Only when we knew we had lost compression issues.

@@michaelcroos4713 Apparently you are not knowledgeable or experienced on this topic. Premixing will only cause damage and there is absolutely no proof that this ridiculous practice is beneficial.

@Johnny Street Sign Johnny you are the uneducated person that thinks that Wankel engines are 2-stroke.

@Johnny Street Sign You are attempting to explain things you clearly do not understand. It's obvious you do not have a firm grasp of the fundamental principles of the Wankel engine. All Wankel engines operate using the 4-stroke principle. 2-stroke engines do not recieve oil directly into the combustion chamber. The cylinders and pistons recieve lubrication from circulating the oil through the crankcase... a completely different concept from the 4-stroke Wankel engine.

The U.S. does not use RON, it uses AKI rating system.

Rotary engine specialists in my country that repaired hundreds of rotary engines said that 95 is good enough. Using higher octane petrol is a bit of placebo, the rotary engine is a low compression engine so having higher octane will not make much of a difference.

It is not, especially if you have catalytic converter. Also, you will have much more carbon inside the engine. Our rotary specialist here is doing those engines for years, running tests on his race cars, and he doesn't recommend premixing. It's better to retune Ecu to put more doses of oil, especially on idle, cause factory they don't add much, because of the emissions.

@@does_not_matter_91 thanks dave best regards!

@@henelulu don't get me wrong, premixing have its purpose, but it's best if you just go nuts most of the time. Track time etc, it's great. For daily driving, going long trips with steady rpms, it will not burn as good :)

You should never premix or use 2-stroke oil in an engine manufactured with metered oil injection. Carbon build up in a modern fuel injected car is caused by low compression due to damaged seals. Premixing lowers octane and damages apex seals.

@@does_not_matter_91 Mazda does not recommend Premixing and only recommends API SL or EC-GF3 4-stroke motor oil. Never use 2-stroke oil in a Mazda engine. Any questions?

How could high octane fuel be beneficial for an engine that needs replacement? You are just foolishly wasting your money.

@@sandervanderkammen9230 Because i wanna drive it and since it needs a rebuild anyway i decided to just kill the engine till the last moment before rebuilding it. And i mean, with 102 octan its quite smooth ngl.

@@revan2814 What is your point? You are still just wasting money, high octane fuel is not beneficial to an engine that has already failed due to compression loss. You need to stop living in denial and just replace the engine or scrap the car.

@@sandervanderkammen9230 did you watch too much gordon ramsay? "stop living in denial" Of course im aware that this engine needs to be replaced. I drive my rx8 very rarely anyway, but when i do than its with 102 octane so doesn't fuck it up so hard.

@@revan2814 High octane fuel is just making it run worse, and the sad thing is you don't know that. I read a lot comments about the Wankel engine being unreliable because their owners don't take proper care of them. This isn't actually why they are unreliable but I think in your case it certainly applies. Get your car fixed properly and stop being an idiot.

Basically the same engine but with better lubrication, I'd say if you can verify that your OMP is working well, you can still premix but use lower quantities, and yeah get rid of the cat

Don't listen to these fools, Premixing is a monumentally stupid waste of time and money and will cause damage to an otherwise healthy engine.

@@goldenrotorracing ok great. My instagram is japanda_tuning, or you can email me at japandatuners@gmail.com Thanks!

Carbon build up is due to incomplete combustion and low compression or someone who has been using the wrong oil. 2-stroke oil causes excess carbon deposits. Only use 4-stroke engine oil that meets the minimum API specifications recommended by Mazda. No available 2-stroke oil meets these specifications.

@@sandervanderkammen9230 tell that to the ppl who run 4 stroke oil, get carbon build up, then blow the engine when the chunk of carbon falls back into the chamber. Lots of RX-8 engines die that way. Second or third after clogged cat (due to failing coil packs) and overheating (due to old coolant corroding block)

@@Soravia You mean all the people driving around on an engine that has low compression due to bad seals??? Then explain why would you use an oil that produces more carbon deposits??? Mazda only recommends 4-stroke engine oil API SL/EC GF3.

@@sandervanderkammen9230 WRONG AGAIN! Those are DAMAGED chrome. Either from lack of oil in S1 or carbon causing the seal springs to not work right and the Apex seal jump over the chrome and leave marks. S2 doesn't have those oil issues and live up to 160k, then BOOM, and the Apex seals are still there. kzfaq.info/get/bejne/arWCm6ZnsJeonJs.html

@@Soravia The primary failure mode of all Wankel engines is low compression due to damaged seals. This is completely unrelated to lubrication issues or materials. Carbon build-up is indicative of incomplete combustion usually from low compression or not following the proper lubrication and specification of motor oil. Why would you use an oil that produces more carbon deposits than than the oil specified by Mazda? Nate Rist is no expert on anything regarging engines or automobiles he is nothing but a uneducated amateur.

R3 has another oil injector so you should be fine without premixing.

Where does the omp spray oil? Is it seperate from those 2 holes?

@@chinchy111 You don't want the oil to spray-out in a fine mist... that wpuld allow the oil to burn with the fuel and damage the engine, that would be a bad thing. This is why Mazda does not recommend Premixing. Premixing = BAD

I run the sohn adapter in my rx8 and it’s great I don’t have to worry ab topping off my oil all the time and I run idemitsu premix so Ik my engine is as safe as can be I also premix on top of having the sohn adapter for that added lubrication

The Sohn adapter is a waste of time and money... never use 2-stroke oil in a Mazda RX engine.

@Johnny Street Sign All Wankel engines use the 4-stroke operating principle. Mazda developed a metered oil injection system for the simple reason that it is superior to Premixing and avoids or limits some of the serious disadvantages of Premixing. Mazda only recommends 4-stroke motor oil and does not recommend Premixing.

@Johnny Street Sign Actually no, you are very confused and misinformed. *Encyclopedia of Automotive Engineering:* Engines, Fundamentals Volume 1, Part 1, Chapter 10, Page 532, section 2.2.3.2 Quote; _"Wankel engines work with the four-stroke principle"_ ISBN 1111130493

@Johnny Street Sign So why did Mazda use oil injection on cars sold in countries where vehicles where not required to have any emissions equipment?

Castor is way worse for anything inside the engine, including seals and rubbers. Just go with mineral, 2 stroke, low ash or ashless oil.

Premixing is monumentally stupid, pouring the wrong oil down the wrong filler hole just proves that the people that but these horribly unreliable cars are not smart enough to care for an automobile.

Never Premix

@@sandervanderkammen9230 hi

Its not specific to the type of engine, but depends purely on the compression ratio. For renesis engines the compression ratio is high (10:1). This is the ratio between the largest volume of air to the smallest (compressed) volume of air. For a high compression ratio, a greater volume of air/fuel mixture is being compressed which raises the temperature greatly. If the octane level is not high enough, this addition of heat from compression will cause predetonation (bad). A higher octane level in gasoline is more resistant to this, so that's why you should use 91+ in all high compression gasoline engines.

@@PeterArmour The Mazda 13B-MSP engine also lacks the high swirl or "Quench" chamber technology found in modern engines. Wankel engines suffer from both the disadvantages of the old flat-head type and the old Hemisperical chamber. Poor flame propagation and a large surface to volume ratio mean the Wankel is more prone to both pre-ignition and erratic high brisance combustion i.e. detonation with the same static CR and fuel octane rating. This inherent design flaw is one of the major factors in the Wankel engine becoming obsolete in 2012.
