well i guess you have it all figured out. why did you start this thread??

which tried and true flash are you running... o it is the one that has been updated isnt it...

good luck.

beers :beer:

I'll be getting the flash if mine requires it. They will only be adding extra fuel at lower RPMs and probably for extended periods. I don't really feel like adding another $2 per fill-up (every 4 days for me). Assuming I did my math correctly. About 7oz of premix per fill (Average about 14 gallons per fill) so a little over 4 fills on an $9 bottle of premix.

Now if it fixes the marbles in a can issue I'd start using it.

the flash adds oil to the motor.... not fuel....

as to the premix... i started with 5 oz per tank... i got it down to 3 oz. it was enough to fix the problem... i dont know what "premix" you are buying, but you can get syn 2stoke oil for about 4 bucks a qt...

do the math... less than .50 a tank..

but i would only run it if you have a problem.. and autox or track days.

beers :beer:

swoop, what brand are you using? I bought some special rotary premix, but it comes to $1.60 per fillup.

learn how to spell my name and i might tell you..

beers :beer:

I'm not swoope, but I use Valvoline TCW-3 two-stroke oil. 4 oz per fillup.
I have these neat 4 oz plastic bottles that you can get in Target for like a buck or so, and keep two of them filled up in my cupholders. Fits there perfectly and I don't use the cupholders anyway because I don't drink (or eat) in my car.

Isn't the E silent? :)

Tamas, Thanks. looks like rx7 owners use that too.

yea,
like i am french. to funny.. so far i have used anything that said syn 2cycle oil.... got it at pep boys, walmart, motorcyle shop.... i have paid 99cents for mobil 1 / a pint. to 15 bucks for a qt of bel ray super racing. did not look at price before i put it on the check out counter..

the best bang for the buck. walmart... but you have to be near a marina... which you are...

while in naples i have found it... comes in a grey container it is like 4 bucks a qt...

i keep 5 oz dixie cup in the trunk and the qt in the pass through cubby...

i had it down to 3 oz before stopping..

beers :beer:

Swoope, I know you've probably mentioned it many times before but what was the problem you were having that the premix solved--rough idle??

Sorry guys, after two full days at Infineon Raceway...my brain is toast. :crazy:

sudden power loss at cruise...

beers :beer:

I don't have it figured out. That's why I started this thread to see if others agree or have differing opinions.

My thoughts just make sense though, i.e. inject more motor oil=more deposits.

I don't know which I have but it's probably the R flash.

injecting more oil in the motor premix vs mop. is different...but not that...

and yes this is stuff i do know.. as you can see from the post above...

how long have you had your car. how many miles. what is the build date. when was the last time it was at the dealer?

beers :beer:

build date 4/05, I bought it new with 20 miles about 4 months ago and now has 1400 miles on it. Never been back to the dealer after I bought it and I don't plan on bringing it back due to incompetencies noted on these forums. Regardless, I will just add premix for now until this all settles down and Mazda gives a clear explanation as to what the issue is.

I can understand why some are reluctant to get the new flash.....how many years has it been and we're stilling having issues with new flashes. People have blown engines because mazda can't get it right the first time. It's just a shame so many have to go through this process of being the guinea pig.

I starting premixing awhile back and luckily for me, it probably saved my engine. The unfortunate part, two of the local dealerships have horrible service and I'm stuck dealing with them, unless I want to start traveling, LOL. They haven't been of any help since I bought the car in October of 2004. I ended up replacing so many parts out of pocket, including having to pay for flashes, since I have "aftermarket performance modifications". :rolleyes: The car has only 9000 miles and now another recall, :yelrotflm

Sometimes, I wonder what I got my self into. :hahano: The funny thing is....I love the car and will end up keeping it for a loooong time.

well you do not have the s flash, and you are making a big mistake...

i have given you all the help i can.

good luck..

beers :beer:

which flash has caused the blown engines... if you paid money to flash you did not do your homework... it is part of the emissions system... sorry you fell for it, but you are to blame.

you were smart enough to find this place.

beers :beer:

And everyone here has all the answers? :rollingla How am I to blame for poor service from these bad dealerships? A car, in my opinion, was released prematurely, has these problems, not small by any means and I go in with modifications and the dealerships won't be of any help...... No big deal though, I not losing sleep over it. I just chalk it up as a lesson learned.

guess i am lucky to deal with a good one.... they have nothing said about the list of mods in my sig...

maybe i handle them in a different way??? you tell me. i have a bit of premixing in the past.

what problems did premixing solve for you?

and this is an honest ?

beers :beer:

I'll be getting the reflash, no premix - mainly because it's a lease, and if there's a problem with the car right before I turn it in, I need to be able to honestly say that I did everything exactly the way they told me to.

But if I owned the car and planned on keeping it, I'd get reflashed and do the premix.

GTAW, unless they can prove that the modifications are causing your problem, they're bound by law to honor the warranty. Check the Moss-Magnusson Act.

and to all that have not read these docs.

please do...

thanks for all the hard work zoom..

bump

premix with syn2stroke oil no.

popcorn good?

beers :beer:

I found the First Dealer Letter to be interesting. Please Note i) and ii)

"i) The oil-injection metering system may be inaccurate causing poor engine sealing of the combustion chambers resulting in drivability or emissions problems.
"ii) Too much fuel may be injected at the time of engine start causing carbon to be deposited on spark plugs or plugs may be flooded, causing a difficult start condition. In addition, the catalytic converter may be degraded on some vehicles."

Engine Oil is NOT the cause of Carbon deposit. The new flash (of which I already have, and fixed all the idle and Cruising problems that I had) solved the problem. Do I need another engine? Im not sure. I have to bring my 8 in for service anyway(need to replace passenger side rear light, fogging up, also A/C temp. knob)

Pre-mix sounds really great, I think I will try it one day. but just gonna Wait until the gas price to go down to under 3 bucks a gallon(Its 3.37 rite now, dropped 20 cents in a week, YES! ok, call me a cheap bastard :-P, 2.99 is fine for me!)
