I've read this before as well, and I am not saying your wrong, but if this is indeed the case, why are the injectors angled to the sides like they are aiming at the side irons?

If they don't spray, then they would just "drip" down on the rotors and never get to the side irons like it looks like it is intended?

TALAN7

Perhaps someone could tell me HOW to remix?

TALAN7

That would be Premix!

Jax, it just seems to me that "spray" is impossible, given the flow rate. For example, while I typically consume a quart in about 1200 miles locally, on a straight cruise-control highway trip oil consumption is around 1 qt per 3000 miles. At that rate we are talking about something on the order of 1 drop of oil per mile - for the engine as a whole! It would be exceedingly difficult to affect anything resembling a "spray" in this case! Any angling of the injector nozzles may have more to do with getting the opening to be in the desired spot of the housing (i.e., closer to the edge).

I think when people hear "injector" the image of a fuel injector spraying gas comes to mind. With the OMP injectors, it would seem to be more of a slow drool.

Go to Wally World - buy 2 quarts of Marvel Mystery Oil.

Go out to your car and go to the gas station
take off gas cap
add 16 oz of MMO to your gas tank
fill up with gas

add 8 oz to every fillup going forward

enjoy the fresh peppermint exhaust!!


BTW - read you other thread - this may help with your running issues as it will clean up plugs, combustion chambers, and catalysts - but will do nothing for all the other potential ailments that may be causing your rough running.

Jax_RX8

I tend to agree, the angle just seems strange if there is not enough pressure there to get the oil over to the side. Who knows, but this is just one of the many reason I premix - it does spread the oil everywhere.

A fluid will conform to the shape of it's container.

TALAN7

Thanks, wasn't sure if you just did this at the fillup or if it required some elaborate mixing of things.

TALAN7

would something like this be considered premixing in that it also lubricates.

http://www.gumout.com/products.asp?products=1_11

It's supposedly has amines in it, whatever that is. I was going to use this but instead just put the cleaner instead.

Jax_RX8

No - this is almost totally a fuel cleaner - very little lubricity added.

Premixing is mostly 2-cycle oils, with some "lubricious cleaners" that add lubricity as well as the cleaning they do. See this post for my listing

Guess I'll be switching over to MMO....

So much for that almost entirely full case of Idemitsu I'd been waiting months for.

Now I just need to find good 8oz bottles to fill and keep in the trunk. Right now I'm using the OEM botthles and a funnel and getting the IRP everywhere. Someone posted a link to what looked like perfect aluminum bottles online, but that distributor stopped stocking them. Any suggestions?

There are so many opinions out there on what to use and what not to use. I love my car but I'm just not going through the trouble of mixing formulas. I want a one solution fits all approach. After years of postings on this forum I thought Idemitsu was it, but now it seems like MMO is the way to go. Although I thought a while ago there was some skepticism surrounding MMO. Has more information come to light which suggests this is "the" solution?

Oh and is the MMO cat safe?

Jax_RX8

Don't get me wrong - all of these products have their strengths and weaknesses- - you just need to judge what you are trying to accomplish and pick the right product for that.

MMO is a good choice, but so is Idemitsu (or another 2-cycle) with some cleaning additives as well (FP Plus, etc) - you just need to choose how you want to proceed.

peterlemonjello

I'm sticking with 4oz. Idemitsu per tank. There's debate about MMO being cat safe. To be fair there's debate about Idemitsu being cat safe too. However, Idemitsu has been used in rotaries for a long time and has a very good reputation.

rx8convert22

My method is 4oz of Amsoil Saber Pro 2 cycle every tank. For carbon before every oil change I do a tank with no premix and add a can of SeaFoam. Every 25k miles or so I plan on using BG44K instead of SeaFoam.

That is my 2 cents. My goal is to have this car for well over 100k miles. Feel free to pick it apart if you see major flaws in this...

I use Idemitsu and am very happy - I have a supercat and it does not seem to effect it. Where were you trying to buy the Idemitsu - my case of quarts only took two days from Mazdatrix. Since I only use 4oz per fill up, 12 quarts should last me quite a while. I am awaiting CRH to come out with his oiling system so I can use Idemitsu exclusively (no more dirty engine oil).

Zephyrzone

I'd ordered the Idemitsu back in August from Mazdatrix when there was a severe shortage. I understand it's easier to get now. I've been using 6 oz per 12-13 gallon fill-up. It seems to help smooth the engine out, but I'm concerned about carbon build-up. Jax seems to be the resident premix expert so I'm going to try some MMO and see if I notice a difference. I've got PLENTY of the IRP and a lot of people seem to trust it, so it will all get used eventually.

On a side note, I just filled up a few days ago. In a typical week I drive rather aggressively and red line often in suburban/city driving. I almost always get 50 miles per quarter tank. This week I decided to go as EASY as I could and try for the best mileage possible. As you all know, this is very difficult in our cars. But I've been shifting before 4k EVERY time, accelerating slowly and letting the car warm up for one minute going anywhere. It's also been 60-65 degrees F here in MD. I figured my mileage would go up dramatically. Nope. Hit the quarter mark today and I'm at exactly 50 miles on the ODO.

No matter what I do I get 16.5MPG if I'm not on the highway, it's just that simple. Kind of confuses me really, I'd think that going from aggressive driving and high RPM's to super light driving and low RPM's would have some kind of impact...

I'm not complaining mind you, 16.5MPG is acceptable for me. I'm just surprised my driving style didn't impact the mileage.

PS- Phil, I'm sure you've had the question a million times and I've read your Vegas posts- but where did you get that avatar? OMG.

Quick off topic: A young lady that I met at a convention here in Vegas. She was doing some movies and sent me stills and a video. If you can get your eyes to wonder a little you will notice that she is playing a Vegas Policewomen. I just thought it was an appropiate avatar seeing that I live in "Sin City" and qualify as a "diry old man".

heard this before - it seems the number of starts ( especially cold starts) per tank has more effect than driving style ....

Arrrrex-8

I picked up 2004 6 speed GT with about 34000 miles 1 1/2 weeks ago. I finally finished reading this entire thread. I plan on going and getting some of the amsoil locally until I can order the idemitsu premix, and then using some cleaner also. Though I haven't decided which one yet.

One concern I have that I haven't seen mentioned, with the amounts of premix were talking about being so low it probably wont be a concern. But I want to be sure. I've read that some people may have had issue's of clogged fuel filters and/or pumps, what about the fuel injectors. Anything to worry about?

Also I'm the second owner, I bought it from a dealer so I don't know the original owner. But I have found reasons to suspect that it was a woman, no offense to any of the women on this list. But I think that this means that the chances this car was driven mellow, which can cause carbon build up in these engines, is much higher. So I was going to see if I could get the dealer to do the engine cleaning under warranty. This assumes what I read about the powertrain warranty extension is true. My car was originally sold 9/22/2003, so I may have 6 months of warranty left if it is indeed true.

Is it ok to start the premix regimen now, or should I wait until after taking the car to the dealer?

Thanks
Mike

I remember reading a few times on here some people saying to only use Amsoil Saber Pro (if your going to use Amsoil) as its the only one thats truely synthetic.

I dont understand where that comes from. Its my understanding that ALL Amsoil oils are synthetic.

Ive decided to give Interceptor a try. Called Amsoil support and asked them what the differences are between the 2 ? They say its pretty much the same thing except Interceptor has more cleaning agents and detergents. He said either one is a good choice for rotary engines, but Interceptor will help with the Carbon buildup.

Seeing as allot are combining Premix with UCL, MMO or some other cleaner, might as well go with a Premix that already has some in it.

In any case. I still have 2 doses left of Saber Pro, and then I'll be switching to the Interceptor.

BTW, another reason Im going for Interceptor is I can find it at Canadian Tires (same as Auto zone or pep boys) for 10$ a quart. Where as Saber Pro I can only find in bike shops for 16$ a quart.

This is a great thread.

I read through a lot of the 40 some pages at 50 posts apiece and was nicely educated on premix.

From Jax it seems as though MMO is the way to go, easiest for me anyway.

I just got the 8 back after going some rounds because of the ignition misfire. big story. (Edit: I finished reading what they did: They didn't replace the cat)

I'll post in a different thread about the different ratios.

It's nice to have back and it's running great. Probably better than ever.

My question is should I go ahead use the MMO now, because of the new cat and all, or wait a couple of tanks?

I want to go ahead and add 8-10 oz of MMO to a tank and take it for a freeway cruise just to check it out.

I'm wondering if I'll notice a difference.

After going down at 25K in almost 5 years, I want to drive it like I stole it.

It seems to me that the pre-mix crowd is like those who unnecessarily pump their bodies full of vitamins even though their day-to-day diet is fine. Thing is, the body can just crap out all the unnecessary vitamins, but the poor old rotary can do only one thing on a pre-mix diet: make more carbon. It would be great for someone to survey whether carbon problems can be correlated to the pre-mix crowd. My guess is yes.

.....those who unnecessarily pump their bodies full of vitamins even though their day-to-day diet is fine.

Are they not allowed to believe their diet is incomplete?

.........whether carbon problems can be correlated to the pre-mix crowd. My guess is yes.

My guess is no. So what?

.........the poor old rotary can do only one thing on a pre-mix diet: make more carbon.

Any evidence? ...or is it another of your guesses? Ever seen the smooth shiny finish around the oil injectors in a wankel housing? I have, and I will bet my housings are still chromed and smooth all the way round.

(My bet trumps your guesses, see quote below from a fellow Australopithicus....)

The dealer will do the new flash if you take it to them, but the engine cleaning is only if you are reporting rough running or other drivability issues. If you do suspect you have any issues, then tell the dealer you are running rough and get them to do a compression check first - if there are issues, they will do the engine cleaning/soak to try to restore some compression - if this does not work, then a new engine you need. They won't just "do" the engine cleaning for no reason.

If you don't have any rough running issues, I would recommend running a good cleaner through one tank of gas (BG44k) and then start premixing with your whatever your preference is - it won't hurt to do this before going to your dealer for the flash (again, assuming you are running OK now)

Jax_RX8

AMSOIL Saber 2-cycle is not, AMSOIL Saber Professional 2-cycle is full synthetic.

I agree it is a good 2-cycle with better cleaning, I just have never been sure it was cat-safe - did you ask?

Assuming it is cat-safe, it would be a good one to use that may not require as much (or less often) use of supplemental cleaners
