premix
the person i bought my car from said 6 ounces of 2 cycle every 5 gallons of fuel.
what is the correct ratio?
PS i have no OMP, so i depend upon premix.

thats a lil rich from what i usually run. I usually slap in 1oz per gallon. that is usually the rule of thumb. Be sure you use TWC3 rated oil, as it is rated for fuel injected engines.

what did you use to get rid of your OMP? My engine is getting a rebuild, and I'm going to run straight premix. From what I've read so far, People put a quart in for a tankful (I believe).

unbolt the OMP itself, take the cog gear out and slap on a block off plate there. Try to get it at least 2mm thick, but try for 3mm (the block off plate) Then just go to where the OMP injectors were and put short bolts to seal them up. You can take your oil injectors to "Lowes" or "Home Depot" to get the right thread and then just purchase four bolts from there. Simple as that. Oh yeah, and put a cap on the vac line outlet on the Dynamic Chamber from where the OMP vacume spider was.

Hm... I think it was half a quart. Well, the goal is a 100:1 or so ratio from what I've read. As for lowering octane, I'd rather have a lower octane than have loss of compression.

Well, you do your thing, everyone else will do theirs. Don't argue with me about it; if you want to argue about how much premix to put in, go argue with someone that does it now, there are a quite a few threads. You obviously haven't read them.

its like a 128:1 ratio with 1ounce per gallon i do beleive. You should see how much oil the stock OMP uses at idle and WOT and then ******* find out how much fuel the stock fuel injectors put out at idle and WOT. Then compair the two and add the amount of oil per gallon so that when the stock fuel injectors are putting out the same or a lil richer than the stock OMP does at idle and WOT. If you want to be a bitch about it you can figure it out yourself.

Fact: I burn 1 quart of engine oil every two tanks (500miles) of gas. Thats about 128:1. I drive aggressively.
Fact: On long trips, I am lucky if I burn 4 ounces for each tank of gas which equals about 500:1. Long trips = lots of consistent speed/wimpy driving.
Fact: If I disabled the MOP/OMP/whatever, I'll run at least 128:1 or more(100:1, 90:1....).
Fact: I don't care for the eco-weenies(attacking boat/watercraft industry) who are forcing the oil/gas ratio to thin out. I want ashless/sootless lubrication. 2-stroke oil can provide this. Engine oil can't. There is no issue with catalytics and 2 stroke oil. If anything, your cat will last longer when compared to running engine oil.
You said that the previous owner used 6oz for 5 gallons.
Thats about ~105:1. If the car runs good with this, stick with it. Use quality 2-stroke oil that is tcw3 certified.
Fact: TCW3 means it is environmentally happy and has an ash/soot/wear limit. Nothing else.
Some cheap tc-w3 oils may trade off lube quality for less ash/soot. http://www.wakerunner.com/whytcw3.html
Stick with a popular name brand oil.
Fact: If your TC-W3 2-stroke oil is not listed here, http://www.nmma.org/certification/pr...il.asp?bhcp=1, then don't use it.
Concerning octane change, unless you are a chem/petro engineer, don't make statements. If you are worried about it, run a higher octane gas.
Two things to consider, when using premix, we are using the fuel injectors. If you premix 1%(100:1), you just leaned out your airfuel ratio by 1%. Since most NA's run rich, this shouldn't be an issue. It might actually help. For the T2 owners, you should have an airfuel meter/safc/ems/whatever and adjust accordingly. Some people forget that Mazda's oil injection was separate from the fuel injection. 1-2% might be risky for turbo owners with ragged tuning.

deadRX7Conv pretty much summed it up.
I run 120:1 of Valvoline TCW-3, low ash, low smoke, pre-mix.
For hard racing, I have ben told 150:1 is safer.
I have chart made up for different amounts of fuel and premix, that I keep in the car, since I don't always fill up.
