You're getting a bad 02 sensor because you're using 87 octane gas.

I’ve always wanted a RX8 since I was kid playing need for speed but a lot of people tell me it’s unreliable or you need a lot of money to keep it reliable so I never got one

*Wankel engines are inherently unreliable and their is nothing that can be done to make them reliable.*

You have to be monumentally ignorant to pour the wrong oil into the wrong filler hole son. If you cannot read your owners manual or the label on a bottle of motor oil? C ou have no business under the hood of behind the wheel.

@@sandervanderkammen9230there is a very big difference between 4 stroke engine oil and 2 stroke oil which is meant to be burned. 250:1 is around 280mL on a full tank of gas, less than a pop can amount. It’s just added to help lubricate the apex seals which helps prevent premature wear.

lol 🎉

This upcoming week I’m about to go take a look at a 2011 rx8 and I’m a little excited, I’m also taking a mechanic with me so that he can check if everything is good. That rx8 might be my first ever car if it’s in good condition. I’m confident that I will be able to maintain it like pre mixing and warming it up and a few other things. Hopefully all goes well.

Actually your friends gotta be a small-sized dogs or cats to fit in there.

One hundred and fifty thousand miles from the engine of a modern vehicle is pathetic. Even the most basic econobox that is casually maintained will easily exceed that.

Sounds like the rotary shares some similarities with the two stroke engines.

​@@b.t.2795It's a Dorito stroke engine.

I mean, 150k miles isn't that much. My dad still has his original 96 Supra and it has over 430k miles without needing any major repairs, and he didn't need to jump through any hoops to fuel it.

@@williamegler8771 What's the rev limit on most econoboxes? Not 9k. How hard do they get driven on a daily basis?

I have the complete opposite of this, I drive a great mpg car now because I'm young and don't have a lot of money. But man, as soon as I get a job I am gonna buy an RX8 and drive it until it dies.

*Stop spreading false information, everyone knows that Wankel engines are inherently unreliable and their is absolutely nothing that can be done to make them last longer. These engines lasted on average only 50-60k miles before the compression drops, that's appallingly bad compared to reciprocating engines that when properly cared for can easily last over 250,000 miles.* *Wankel engines offer no advantages which is why they were a failure.*

Needed a new engine at 70k miles... you were lucky you sold it before stopped running

​ Some say with a good maintenance it can last around 100K

You only need to know how to read your owners manual... and the label on a bottle of motor. It's shocking the stupidity of the fools that pour the wrong oil into the wrong filler hole

Horribly unreliable pile of junk.. Fugly as a cheap plastic garden shed too.

They sell for scrap metal prices here...

They have a strap in the boot for holding the oil

You hear alot of excuses why these engines fail so often, none of them are true. Wankel engines are inherently unreliable by design, there is absolutely nothing you can do to make them more reliable.

Ticking timebomb, your luck will run out soon.

Flooding is only an issue if there is something else wrong with the car. The S2 only gives you additional oil injectors to prevent housing wear, but isn't worth much since other parts of the housing wear sooner.

@@mincvinyl *That's completely false and misinformed.* *Flooding and carbon build-up is a common symptom of low compression in all types of 4-stroke and 2-stroke engines and is very common with Wankel engines when the apex seals are damaged or worn out.*

It has nothing to do with maintenance or use. Wankel engines are inherently unreliable and less durable than reciprocating engines, this is a irrefutable fact that many fans reuse to accept at their own peril. Some fan go to extreme lengths to concoct elaborate and proposturous rituals, excuses and theories.

They are horribly inefficient

Wow, you must have owned some really horrible piles of junk before the RX8...

Yep. The auto cars had a 4 port engine, the manuals had 6 ports.

They did have less power, to the tune of 50 WHP less due to less porting on rotors. those examples despite being automatic will take FI "much" better. thugh Though, no one would spend 20k turboing 10k early 2000s mazda sports car.

​@@aaronbritt2025they had die 4 port 4 Gear automatics in the beginning and later 6 speed with 6 ports detuned to 210 HP by lowering the max rpm for the gearbox.

Just make sure you use 2 capfuls of chainsaw oil every fill up!

How does it handle compared to the 8? Chassis I’ve heard is more rigid like you said but is the extra weight super noticeable? Kinda curious since that may be my next target for a car after my RX8 haha, been wanting to get into the ol American V8’s at some point

@@mrodri1012You definitely feel the weight but, the width, extra torque, wide tire’s & steering on the Camaro makes it feel more solid and glued to the road. IMO The RX-8 feels more toss able and easier to rotate In corners tho.

My 98 Sentra consumes that much oil ...now....

They're supposed to consume oil. The engine actually has oil injectors. Perhaps he should have read the owner's manual.

​@@aaronbritt2025sounds like junk to me. Glad these things are gone.

@@bldontmatter5319 I'm sure they're glad they never met you either.

Yeah the 1000-1500 was what most reported on the mazda forums when I was looking at one of these in 2006. In fact no one reported going 3K miles without adding a quart . I would have been okay with that not like I care about the earth but there were a bunch of posts about engines failing and even one where some guy said Mazda was trying to deny him an engine under warranty because somehow they found out he had driven the car on a track. I do have to admit the car was fun to drive.

A mediocre sedan at best, definitely not a sports car.

I drove a 2004 one, even with the crppy old tires, the handling thru the bends was better than my S2000.

@@salihahzem Your S2000 must be a worn out, beat down, pile of junk

@@sandervanderkammen9230 It was 12k miles, the most pristine one you can imagine; drove it for 2 years and sold it after.

Why isn't swapping the RX-8 into the smaller, lighter NC MX-5 more common? I understand that the swap is fairly straight forward since both cars are the same basic architecture underneath.

It's a Nightmare car.

It's the worst sedan Mazda ever made

@@sandervanderkammen9230 your the worst sedan your mother ever made

They are all unreliable.. Absolutely a car to avoid

*It's shares the same chassis as the Miata... but the Miata handles so much better. The RX8 is Sedan, not a sports car.*

@@sandervanderkammen9230 I don't understand your comment, I said nothing about the MX5. But since you mention that it is sporty and the RX8 is not because it is a sedan (nor is it more of a coupe), you are very wrong. The RX8 is much sportier than an MX5, and I'll explain the reasons: 1. The torsional rigidity of the MX5 NC is 10,000 nm/grade while the RX8 is 30,000 nm/grade, one of the best compared to any car. Roadsters are usually very poor in this aspect due to the lack of a roof, which is key for the suspension to work well and the wheels to support correctly. 2. Height of the center of gravity, the MX5 NC is 47.5cm high, while the RX8 is 45.8cm, thanks largely to its smaller and lower engine. 3. The RX8 has a much longer wheelbase, which allows for less weight transfer between the axles, which in turn allows for better braking and benefits cornering, since the more the weight is distributed between the 4 tires, the more they grip. 4. The RX8 has shorter overhangs. The weight on the overhangs generates more resistance to turning the car, more understeer and oversteer. 5. The engine offers less vibration, greater smoothness and faster response than a piston engine, in addition to being more powerful and going up to about 9500 rpm. Sorry, but the RX8 is not only a sportcar (even if you say no), these data say that it is also a very good one, and much better than the MX5.

@llavero5 *I see there are alot of things you don't understand...* *Like why the MX5 is the most popular track car in the world and why it's the best Mazda sports car? Or why it's the best selling 2-seat convertible sports car in history!* *Please tell why the RX8 was a 3 billion dollar failure? and the reason why Mazda discontinued the entire RX brand?*

*There shouldn't be any excess pressure in the cooling system if the engine is not damaged already.* *2-stroke oil should never be used... Mazda only recommends API SL rating or better.*

@@sandervanderkammen9230 I don't talk about feelings, emotions, preferences or opinions, I talk about facts with data and numbers. The MX5 is fine for hairdressers and divorcees, people who prefer the wind in their face at the expense of the torsional rigidity of the chassis, nothing bad if you are one of them, plus the RX8 is delicate/dedicated and more expensive to maintain. But in terms of sportsmanship, my previous comment is indisputable. Discontinued RX brand? rotor engines are bad for emissions, plus sport cars dont make much money as mass people car.

Wow, that's the most gullible and niave comment ever posted on KZfaq

The apex seals have not been an issue since the 70s. The stories of people blowing their seals tend to come from people who don't know what they are doing tuning wise, but still decide to tinker.

@@mincvinyl Can I trust RX8 apex seals to last as long as piston rings in a reliable non rotor engine? Just seems like 1 more thing to worry about.

​@@foellerd Like I said in my comment below. A rotary should be refreshed every 80k miles, but most people go to 120k miles (rebuild every 10 or so years assuming avg 12kmiles/year). Most factory built rx8 engines would hit around 120-130k and then get a coolant seal leak. Any dying younger is either a lemon or someone not doing basic oil changes. If you are trying to compare the lifespan of a purpose designed sports engine vs a daily consumer designed toyota corolla engine, I would say that comparison doesn't make sense. The best comparison is probably to the BRZ/86, which is the piston alternative to the Rx8. 15-20 years newer design and you could get 150k-200k miles on a brz before a refresh. The Rx8 does pull on the brz in a straight and has a better suspension though. Being newer the BRZ/86 will have a considerable aftermarket community. If you are looking at cars you should really lay out what models you may want and then what you need from your car. If you are looking to simply get groceries for 500k miles without changing your oil, these types of cars are not designed for that.

@@mincvinyl *You sir are a bald faced liar.* *No one has ever solved the reliability problems with apex seals.*

@@foellerd *The apex seal will never last as long or be as reliable as a piston ring, this is an irrefutable fact that cannot be disputed with credibility.*

You will stall Rx8 all the time, any piston car is easier to drive.

@@sandervanderkammen9230 the rx8 was never about performance so what exactly is your point? The ry8's weight distribution makes it a perfect car for curves, and an fd swap makes it a perfect car for time attack and general racing without ruining the 50/50 weight ratio. Its also easier to get parts for it compared to the rx7 and the rx8 has huge potential for value gain as it was the last rotary ever build

@BeHeaven616 *True, Mazda is not a performance marque, it's the smallest, least successful of all the Japanese automakers, a company recognized in the industry for building cheap, entry-level economy cars for first-time buyers and non-enthuestists.* *Mazda's forays into Motorsports was an embarrassing failure with the company leaving racing in disgrace, they no longer have any factory racing program.*

Unfortunately the primary failure mode of apex seals has nothing to do with lubrication, of course if you don't check your oil no engine will last long.
