taking off the UIM is not hard bro. Getting rid of the vac lines helped my idle a lot.it went from idleing at 1300 to 7-900RPM depending on the weather. I think you can't do that because you would need to plug the oil lines on the injectors so either way you need to take it off and you might aswell remive the injectors and get some bolts like I did.

alright i'll just take it off again... boo. i shoulda just taken them out when i had to replace all the vac lines from the burn damage. I'm still not sure if i got them all right. The vac line to the oil lines comes off of that vac spider right? cuz thats where i hooked it up to.

I think the vac line for the injectors comes off the big nipple on the back of the tb.

What kind of synthetic do you guys use?

The oil injector lines are hooked to the sider and that goes to the big nipple on the front of the UIM.

I still use mineral oil in my car I don't want to use synthetic yet. I might try it out next oil change but I don't know Mobil One is pretty damned good



Oh and I use Coastal two stroke oil. pretty cheap about 2 bux for a quart.

Does premixing shorten the life of the spark plugs and cat?

I would think it would help them last longer since two stroke burns cleaner.

if you premix then you can run synthetic in your car, assumming you don't do half permix and half OMP, i am 100% premix and using castrol syntec 10w30! This is another advantage to premixing!

I would like to know the advantages of running synthetic. For the price it better be good. I was thinking about Mobil One synthetic but I need a heavy weight like 10w 40 or more for the summer

I am going through my second tank of gas since i began to pre-mix and I have noticed what appears to be a gas mileage increase. It is not a big one but I think maybe 20 miles more a tank but i am not sure yet. I need to record the mileage for another tank and make sure. Has anyone noticed this when switching ot pre-mix?

advantages:

the engine is cleaner since two stroke burns cleaner.
you use less motor oil since the injectors are not drawing any from the engine
you loose the OMP, injectors, and the lines which can fail and cause your engine to blow
you get funny looks from the guy at autozone when you go buy ten quarts of two stroke and say it is for your car

read this: http://fc3s-pro.com/TECH/FAQ/premix.htm


also your idle gets better since most of the vaccume lines have cracks and leak creating idle problems. I think i am also getting better fuel economy too. ofcourse that is offset with the cost of the two stroke but who cares.

i don't know if it would be offset by the cost of two stroke because you are simply substuting two stroke for "normal" engine oil, so i don't think it is offset i would think it would be a "gain".
The advantages of Synthetic is proven by race cars over the world, it allows less friction its point of thermal break down is far better, its viscosity is consistant (to a certain point of course).
But you don't have to buy the best to get good quality stuff quaker states synthetic is good! but just too heavy for me!

I still run the MOP but I do run the lean 1:2 mix of premix especially when I run on the track or do a canyon road run .

well mobil one mineral oil is cheaper than castrol oil that everyone uses and I love using it. I think mobil sinthetic blend is like 2 bux a quart. Well if i am getting what I think I am getting as far as better fuel economy I believe I will break even. cuz I think I am getting an extra 20 miles from each tank gas prices are about 1.55 here and a quart of two stroke ia about 2 bux so divide that by two and you get a 55 cent savings from premixing.

I just say its for my quad or jetski or similar Then they just go "oh yeah, that must be a lot of fun" rather than make you explain why you are putting oil in ur gas tank

So let me get this straight-

you remove all the OMP equipment and lines

you then can run synth oil to take advantage of the better librication properties and longer life

you 'pre-mix' two stroke oil in the gas tank (how much?)
the two stroke oil lubricated the apex seal springs(?) and alows compression between the apex seal and housing

since two-stroke oil burns clean(er), it help the spark plugs and cat and solves the carbon buildup problem

you must now carry a case of two-stroke oil in the hatch area

BRealistic -- READ THE LINK. It will tell you what ratio will best suit your driving habits (racing/not racing.)

As for using the OMP to handle the premix:
Already posted once in this thread by Amur_
2 reasons why the OMP sucks - very low pressure and narrow oil dispersal. If your OMP lines are empty when you start your 7, it will be several seconds, at least, before oil finally gets to the apex seals. And the narrow dispersal means that the entire seal isn't getting coated.

When you've got oil coming in along with the gas, it's coming in at a higher pressure and much wider dispersal, coating the entire apex seals. Premix is also coming in as soon as you crank the motor, so everything is getting lubricated (meaning protected) right from Go.

What's the point in setting up the OMP to disperse the premix if it's going to do a shitty job of it?

The premix I buy comes out to about 93 cents for 16 ounces. I can get it cheaper but they did not have the gallon containers when I was there. I only carry two bottles of two strok in my car not a case. I don't really understand your hostility towards pre-mixing. Leaving the OMP on the car will still result in poor distribution of the stwo stroke oil. and you could not setup a separate resivuoir for it. because it is hooked up to the engine. and it draws oil from there not any ouside source.
