yep about the only thing you can do is to keep the tank as full as possible at all times.

i looked for that post last night... it was during the time lots of pm were flying..

o well at least we have a better idea..

beers

 

I run my tank nearly bone dry all the time. Filter is clean.

 

So basically the issue of dirty filters and premixing might be a bit overblown? Phew...

 

thats the latest----if you have dirty gas you will have problems. pre mix will compund that--but it is thought to be affecting the pump--not the filter. we still have the problem of fuel starvation on the track and fi boys are having problems with the stock fuel system. nothing has been solved--just a better focus obtained.
MM glad yall have clean gas out that way--send me some.
meanwhile us dirty gas boys will keep a high level of gas in the tank so as much sediment as possible can be washed out of the ruel pump unit and doesnt settle. Best lodgic approach i can think off.

But wouldn't you guys just introduce more and more sediment into the tank after fill ups and it would reach a saturation point after awhile where you're forced to clean your tank?

 

Yeah, not letting it go down means it will just accumulate.
You want to keep disturbing the bottom of the tank so that it dissolves as best as it can.
Track days will probably do that pretty well.

 

the thing about it is that you want enough gas in the tank to continue to move fresh gas in and out the little sump tank. Dont run low and let it build up in there.
i dont think we will have any difficulty keeping it stirred up!

If the filter accumulating oil really was the issue it wouldn't just happen under track cornering, it would be a continuous issue that would just as easily occur in a straight line with a low tank level and not just on long track sweepers in one particular direction, totally retarded ...

 

how ya figure that?

Mark is mixing up his symptoms. He's talking about the left-hand starvation issue, not the filter discoloration.

 

I'm not mixing up anything, the LH starvation issue is exactly how this all this fuel pump vs pre-mix BS got started ...

 

Apparently, but it is obviously two separate issues.

 

Wow guess you should get a few extra bottles next time you order premix ~_* .

Thanks for quoting their entire page.

You can still get the stuff, just not directly from Idemitsu at the moment. I have another case coming next week.

 

I never said you could not get it, but if there stock is out that would mean others will be as well once there invo is depleted.

 

I know Mazdatrix is out of their engine oil cause I tried to order some last week and Chris called to tell me they were out.

I did manage to get a case of pre-mix...just in time I guess.

 

Shh! We don't want the heathen to download all of our private stock of oil!

 

Good point. Last time I ran out of pre-mix I started getting the shakes. I didn't know what to do when I went to fillup at the QT.

 

I keep a couple of quarts of the RP stuff around, but it isn't optimal.

 

has anyone removed the omp yet and just ran pre mix?
i currently am on a trial/evaluation of 1 oz per gallon--got to admit--car runs better.
olddragger

 

I have a surplus of premix so I guess I should try selling it at inflated rates!

 

You would have to run 12 to 14 oz per tank for that.
Given your pump problems, I don't know if you would be happy with that.

I run 8 - 10 oz with the OMP still hooked up (but, seemingly, not operating).

 

Whew, 21 pages later....

Ok, finally got around to reading this... Going to start premixing this weekend. I have my list of stuff that will work, so I'll just check around the PB/AZ/AAP to see what they got. I have a gas mileage log with every fillup since I got the car, so I have a pretty good handle on what my gas mileage looks like (18.5 hw / 13 city - "You have a heavy foot! You'll blow yourself to pieces!!")

Anyway, got a couple questions:

1) Anyone using premix in colder climate? I plan to do alot of winter driving, and temps in upstate NY can get to -40 at times. Any issues with the premix clumping or gelling and settling on the bottom of the gas tank?

2) In general, anyone have any issues starting the car after letting it sit a while (say a week or more)?

 

Can we get a summarization of the main points here? All I got was use 1/2 oz per gallon of something synthetic with no castor. And there is a potential premixing will do voodoo to your fuel filter.. Does that sound right? How does something like the FP60 get into picture? Can you alternate using that with a 'real' 2-cycle oil? Or do you have to sit there mixing 2 oz of one and 2 oz of the other?
