thanks MM for the tip on how much is useful to run. i'm not too far off using 6~oz. for street driving on the tank. its kinda funny that i've never heard of any marbles or sand as i premixed driving the car out the lot.
somewhat close to .5 oz to the gallon. but i need a bigger bottle to measure exact how much i'm adding over 7oz. think i should be fine here.

MM- I know it's not "the" reason we premix, I'm just noting that even in small amounts, for some reason, it has helped with this issue. Others have speculated that the marbles/sand sound is coolant bubbling through the heater core, but this noise is probably being used to describe a number of different issues. For me it does sound like a rapid bubbling noise from the glove compartment and if this is really the issue I have no idea why premixing would help. But when I do it does, and when I don't the sound comes back. After more driving and more note taking I'll know for sure if it's coincidence of there is a direct link.
As for the 8oz minimum, throughout the 26 pages of this thread there seems to be a number of different takes on that. At one point someone said 8oz was the maximum, others stick with the .5oz per gallon rule and others still use 4oz oil and 2oz cleaner. Lots of good sources like you MM as well as Jax and Stealth, etc. Still, it seems everyone has their own magic ratio. 4oz seems like the lowest, I don't recall seeing 10oz until now. I thought .5oz/gallon was the accepted general rule.
EDIT: OT- while premixing seems to help, I'm all ears as to anything else I can do to mute that awful blender sound. I already added Water Wetter to the coolant. I've driven 8's that don't have this noise and mine isn't always there- so if you have any ideas please send me a PM. I've been looking for a permanent fix. Thx

I just use what Downing and Mederer set up as guidelines - 100:1 as maximum for a normal motor and 150:1 as nominal. 200:1 as minimal.
If you have an operational MOP, you can use about 70% of the desired volume as pre-mix, so you would use 12oz, 8oz and 6oz to achieve the ratios above.

Got Another Rotary
MM recommended this increased amount to me some time ago and I have been playing with it - having run about 10 tanks through at this rate and the motor sure seems to like it.
Of course I also have Idemitsu flowing through the OMP at a rate of about 2.7 oz per tank as well, so I am right on MM's 150:1 total ratio, or about 8 total oz Idemitsu per 12 gallon fillup.

Grrrr...
Well, my marbles/sand sound is back and I just filled up 7oz to an 11 gallon fillup. Plus my engine sounds very coarse again, whereas it didn't for the previous two tanks. I wonder if between the last fillup and this one I used too much and it dropped the Octane level? It goes to the dealer tomorrow for a new headlight (came from the factory with oil inside the lens) and I've asked the tech to go for a ride along to diagnose the marbles sound. This engine just sounds much coarser, even without the marbles, then the old 7's I test drove. What gives? For a few tanks when I was premixing it seemed MUCH MUCH better, but this time around it's much worse.
Oh, and even though it's OT, I swerved to avoid a pothole today and slammed my right rear wheel into a curb. Nice big gouge around the rim. Makes me want to vomit. My new car rattles, sounds coarse when accelerating, has swirling marbles and now a mangled wheel. Awesome.

(Couldn't resist, considering your avatar
)Sorry to hear that man, but I'm betting the pothole would have been a better option...
On topic, I am finally taking my 8 in to the dealer to get compression tested on monday (it will have 59900ish miles by that point
), so after that I can finally start premixing again!! Premix FTW!!

Alright i have what could be a total Noobie question about premixing but after paging through about 70% of this thread i never actually saw anyone else ask this.
Is it possible just to put normal 5w20 Oil in your gas as a substitute for a premade premix? It seems like since the goal of premix was to lubricate your engine better any oil would really do this...? Although it wouldn't clean it like the premix is supposed to.
Damn i'm really embarrassed to ask that question but i'm just trying to understand my car better and this idea of premixing which seems to be very beneficial.

Premix is designed to, well, mix with gasoline, another is to lube
Dont even try to put a few oz of Motor oil into your gas to see *what will happen*

Here's your (first?) +1.
You can get 2-stroke synthetic oil at any auto parts store, or preferably, cycle shop if you can't wait for online delivery. To sum up what you've already read (and what I just learned over the past few months)- use only synthetic JASO certified 2-stroke oil. Many good brands have been listed. I found something called MaxPower which is smokeless, full synthetic and JASO certified at Advance Auto Parts in Maryland. I'm using it until my Idemitsu comes in...

I have been using the Bel Ray Full Synthetic Si 7... The cycle shop near me said it is one of the best that is on the market that is 2 stroke.... the car has definitely been smooth and more responsive with it... anybody else used it before?

Yeah. Me too. This is good news. Although I just bought some really expensive stuff from a cycle shop. It was $9.99 for 1 PINT. It's JASO FD certified (I guess that means it's made for 3rd gen 7's...j/k). They didn't have much else and I was already there so I bought it. But there's no way I'd continue to spend so much for so little. Can't wait for the Idemitsu to come in.

I e-mailed him last week when I hadn't received my order after two months.
He said it would be this week.
I e-mailed him again yesterday and he e-mailed me right back saying it would go out soon since I was #5 on their list of hundreds.
Shortly thereafter, he e-mailed me again to say that it went out.
They've been very responsive.
