87 turbo II, stock except intake and turbo-back exhaust.

i would say that i probably get about 12 average and 13-14 peak. that's on premium with an occasional octane booster.

08 Mazda RX8 GT 6MT
K&N drop in filter.
Gutted cat.

21-22 MPG last 5 fill ups

Im getting better mpgs when switching to Midgrade gas. i used Shell and only shell.

Midgrade huh... Now do you get different MPG from other gas company?

Well yes, I put Hess wow that was crap. I also put Exxon and I didnt like it. Ive stuck with Shell cause I like the way the car fells. And now I switched to mid grade and im getting better mpgs

as far as the 7's go.. a n/a should run on regular only
turbo should be premium only
8's I guess recommend premium but honestly the rotary engine has no need for premium unless boosted..

I get about 15mpg on the freeway...at sea level on a cold day with a tailwind.

Rich is safe, so I'll just buy a lot of gas, and make sure I redline it once in awhile to clean out the carbon build-up. :)

Sorry for jumping into the rotary party, but originally I thought that getting the mileage that you speak of would scare me out of wanting an RX-whatever. Yeah...definitely hasn't yet, as I am scouring the locals for any for sale. Maybe one day I'll be joining you rotor-heads.

Riken

07-30-2008, 05:24 PM

Its all about how you drive the car. Ive seen people get 26 mpg on their 8s and then people get 15 mpg. So its all about the driving style you chose.

IMO

If this is gonna be your first rotary start with a FC (86-91/2)

They are cheap, more afordable, and IMO alot sportier to drive then the 8.. (no offense Riken and other 8 owners)

I have owned a 91 vert and my 86 coupe. I have driven a few 8's in my day.. the car inside is completely different, the handling is different (but both still VERY nible) however the 7 series are much smaller and give u more of a sporty feel IMO then the 8

the 8 is like a sport/luxury rotary

If you are getting a rotary for sporty purposes try a 7 first.. its cheap and if u dont like it u can off it easily..

if you want something sexy inside and nice on the outside and still a rotary get an 8 but if u dont like i the reslae is gonna kill ya and u may not like what u have ot do to sell it..

I want an 8 one day but thats because I have owned 2 7's and love them and love the 8 but if this is yoru first rotary... the sound, the feel, the smell, and everything that goes allong with being a TRUE rotary guy is in the earlier cars..

IMO the rx8 lost the "prestige" that the 7 series brought to the rotary world as a SPORTS car for its manufacture and time. however the 8 still has the pegigre that the rotary engien cars have..

I would NEVER count the 8 out I love it.
but IMO if u want the abuse and high rpms and sounds etc get a 7 they may a bit more racket :)

I can see that. Hell, I can swing an 8 mpg change with the Protege, and almost a 10 mpg change in the Civic.

To let a small secret out... I'm waiting till I get a few of my bills paid off, and a few bucks saved up, and I am seriously looking into an 8.

Yeah Dave I know where you are coming from. The 7 is smaller. You will need a turbo 7 to get better power than the 8. But when you get on the 8 its a great feeling. You can cruise and play at the same time. Everyone will be like wow nice car. I had many 7s in my days so I can say both cars are great. But you can get a 8 for 13k thats what will move you to get one.

26mpg highway in an RX-8? I planned on looking into this after I got to AZ, but if I could get at least 26mpg highway regularly (on a highway only tank but not dependent on weather conditions and such) I'd replace my P5 with one. I don't even care if it takes a grand or so in mods to get it to that, I just don't like pissing away fuel.

Yeah the most I have done was 23.4 on about 2 tanks, then I gutted the cat and I cant get to them #. But as soon as I went to midgrade now im seen the numbers closing in.

So with going Mid grade you get better MPG but in terms of performance do you feel in lagginess from taking off or under WOT?

Riken

08-08-2008, 11:06 AM

Im not feeling any difference under WOT. Maybe if I go back to Premium.

I still think with the n/a engines premium is not NEEDED... on the FC engines dynos show a GAIN in power when using regular over premium

How does this make sense?

I am no scientist but explain how do you get a "gain" in power with lower Octane?

Where are these dyno facts that you say of?

Then again the FC engines are more primitive than the Multi-port Renesis engines so maybe with they do get more "power" drinking low grade stuff.

Why should a higher octane = more power? That's oil company brainwashing at its finest.

SpooledupRacing

08-08-2008, 04:49 PM

exactly... you have to understand the resoning behind burn etc..

higher octane burns different then regular.. n/a 13b make more power on regular.. this I know

HAHA so your telling me that when you run a higher Octane gas ie: Race fuel between 110-116 octane it must be a placebo effect that car is going faster.

RIGHT!

And how do you know this? Where are you basing your thoughts? Is this by experience? Now your N/A 13b is a 13b-REW ... However! the Renesis is a 13b-MSP. So yes like i said maybe in the older engine might "gain" power but the multi-port with higher compression in theory should run a higher octane. Just like a turbo aspirated car the higher the compression the higher the octane is recommended.

RIGHT!

On a naturally aspirated car? sure thing. If the engine is designed to be used only with high octane (i.e. high compression) then sure, it needs it. Going to 110-116 octane.. probably won't notice a difference if the stock ECU is tuned for 91-93.

Don't listen to the oil companies telling you that higher octane = better --if the car isn't designed to take advantage of it, you're just pissing away your money.

What are u talking about.. my car is a 13B and always has been being turbo does not make it a 13B-REW (13B REW is the 3rd gen TT or COSMO TT engine)

There has been WRITEN AND DYNO proven on the rx7 forums that lower octane makes MORE power on the n/a 13B's (rx7's) then higher octane...

the RX7 n/a engine is 9.7:1 compression RX8 engines are 10:1 so not much of a difference

the main reason for the RX8 to use premium gas I'm sure was to help eliminate detonation but not for power...

SpooledupRacing

08-08-2008, 09:24 PM

oh and the reason for higher octane race gas is a few reasons..

LEADED
RACE cars with crazy compression or high lots of power need it so the car dont detonate or knock.. again it has nothing to do with "making" more power..

the Rx8 stock ECU is tuned for 91-93 octane thats why I dont see why you should try a different octane gas especially it is recomended to use premium gas.

And its not about listening to the oil company, I am following what the engineers that design my car what gas to put in my car.

So there is WRITTEN AND DYNO proven on the rx7 not the 8. Even if the compression my be slight there is still a difference.

oh and the reason for higher octane race gas is a few reasons..

LEADED

Yes that is one of the reasons.

Another reason is that the compression are so high that it will run lean if you don't put higher octane gas.

Anyway this is getting redundant. My average MPG is around 13-15 MPG in the city and roughly 17-19 on the highway.

Riken

08-11-2008, 01:31 PM

Yeah but they also recommend 5w20 lol

SpooledupRacing

08-11-2008, 01:33 PM

yeah I would never run that light weight oil in a rotary..

I use 10w50

9K Redline

08-15-2008, 08:14 PM

My average is 18mpg city & highway/spirited driving.

My "performance" (more for sound) mods are just MS CAI and Dual Sport Exhaust.

I only use premium because I get detonation when it rains hard anyway from my filter being wet before I even hit 6krpms.

I also use RP 5w30. I'll continue to use it til my motor pops, then I'll change for whatever setup I spring for. (Leaning towards Pettit SC)

no its here say I have a buddy who used it in a tranny and his tranny died within about 6 months, after he had it rebuild he used it again and it died in about 6-8 mo.. then when he bought a performance tranny they told him DONT USE ROYAL PURPLE..

since then he has gone 2 years on the built trans.

no sales pitch..

my avg is i think 23-25mpg, i reset my milage when filling up. i get 350 miles to a full tank with 2 cycle, but trying something new i heard about. lucas fuel treatment, supposely heard it works and doesnt leave that nasty oil residue on the rear bumper.

I can add a little more info on this...you may still consider it hearsay...but it is very true.

My father is a GM of one of the ELF/TOTAL plants (Linden, NJ)...ELF (Now TOTAL) actually was thinking of buying Royal Purple based on the buzz they were getting from advertising. However, according to my pops, when they actually visited RP facilities and did research on their so called "performance testing" they found that MANY, if not ALL, of RP's claims of performance were unsubstantiated because they don't even do half of the testing they claim they do. They had very little evidence of any actual research or testing of their own product. After visiting their facilities and researching the RP product versus their own they VERY quickly pulled out of talks to buy the company.

My own personal experience with friends who use RP is mixed...I have heard several horror stories, but I know people that use it and have no problems....but the amount of horror stories I have heard from them, on the forums, and what I have heard from my own pops, is enough to steer me away from it....Plus I dont need it because my dad brings home cases of TOTAL oil for Free every couple months!

IMO thats not heresay thats proof is a guy who SELLS oils for a living went to a factory and spent time analyzing a product and knows its shit..

that would be proof in my book.

Which is funny.. its only Royal Purple owners that say that... until it happens to them

another funny thing is that you wont use the total oil which is CHEAPER in cost then the royal purple, it is a beter oil and you are local and can get it from me for dirt cheap lol..

I dont see your reasoning.. I think you read into to much "heresay" of what others try to tell u gives u more horsepower.

Ok do we have togo through this again?

Let me ask you, why wouldn't I get oil from my friend for a lot cheaper and also support my friends business? Its not the brand of oil, its the type of oil. If you can get me 5w20 I will buy your oil. But you don't have access the oil that I need.

I will not deviate from the recomendation of using the oil that is specified to the company's requirement.

where r u putting thu lucas fuel treatment?

if u are ading it to the gas and NOT running an omp then you will cause damage..

if u are running the OMP u dont have to add any 2 cycle

if u are not running the omp JUST run some TCW3 2 cycle

wow.. really? well, yea... my omp was eliminated when i bought the thing. the guy never told me anything and i heard screeching for sometime because i didnt know that i was to premix. after i found that out i started the premixing, havent had any problems. still running strong, well.. the reason i switched over was because of this thread on teh rx7club forum, but i'm just trying it for now... here's a link to what the discussion was about:

SpooledupRacing

08-23-2008, 10:51 PM

just use regular TCW 3 2 cycle oil

1oz per gallon of gas

AND as for your RX8 and the recommended oil.. how many times to I have to go over this ELF is the one that ORIGINALLY DESIGNED the oil for the rotary engine (Idementsu) they know WHAT REQUIREMENTS u need for the engine.. WEIGHT means NOTHING.. NOTHING at all.

ELF recomends using 5w30 in ALL rotary engines BECAUSE it has the correct formulation for the rotary engine AND because it lacks the stuff that other oils have that leave harmful deposits behind'

Just remember RP was not made for rotaryies and it leave LOTS of ash in the engine.. the reason for the 5w20 is because MOST non synthetic us spec oils are a low ash oil in 5w20

but weight means nothing you have to forget EVERYTHING u know about oil because the US market has been brainwashed into thinking u have to get the right WEIGHT oil for the car..

Weight means nothing it is the chemical breakdown and the amount or lack their of in detergents that u need to be worried about..

READ THIS

http://img.photobucket.com/albums/v88/turboTSI/misc%20pics/elfasianrecomendations.jpg

SEE under Mazda... it CLEARLY states what EXACT oil u need to run in the RX7 and RX8 cars... it is the EXACT oil that that car needs to run efficiently..

I wouldnt sell u oil that would damage your car.. nor would I use it in my own car..

You are acting like the RX8 is that much different its not.. it is a 13B engine same as the RX7 engines they are internally almost 100% same.. and oil has no change on anything about the engine.
