convert to premix??????
 
yea iv read alot about it on here but from what i hear its better for the motor, 1.5 oz of 2 cycle oil per gal is requierd? or is it i full quart for every full tank of gas? i have bought the 2751 block off plates and i have the omp plate for my s4 n/a. one reason why im considering this is im cleaning out my bay and replacing all the vac lines and found the i had a oil "vain" connected to the omp broke off the promary oil injecter in my rear housing :( but yea i can buy some replacement from a hydrulic place or just run premix. idk help me decide whats best for my motor with over 200k and with really good high compression. idk just help im trying my best in researching but need feedback, and ill do whats needed for my car.

for my FCs, I mix 128:1 or 1oz per gallon.

so its completly safe to do this even on a car with 200+K miles on it, all i worry about it the fuel system at first but i read that its cool, would i have to mod anything tho? no right?

install your block-offs and mix the premix like carzy driver stated. done.

forced inducted fd dude 01-10-07 12:24 PM

ok cool so either 1oz per gal or one whole quart every full tank of any 2 cycle oil is good?

ok cool so either 1oz per gal or one whole quart every full tank of any 2 cycle oil is good? what about the oil injecters do i just leave them there and cap them?

diabolical1 01-10-07 03:56 PM

if you're referring to the nipples/nozzles on the rotor housings and intake, then yes, cap them.

forced inducted fd dude 01-10-07 11:56 PM

no also this im wondering. can i run synthetic oil through the motor if i premix?? (stupid question)

note* my car has over 200k miles and burns oil when cold.

diabolical1 01-11-07 05:55 PM

not sure if i want to open this can of worms, but the simple answer is yes.

Chuck 01-16-07 04:04 PM

If the OMP system has been disabled and the oil injectors capped, then yes you can use synthetic oil in the crankcase, and you won't have to adhere to the 2500-3000 mile oil change interval. As for the premix oil, just use any brand that's rated TCW3 and you'll be fine.

ok so all went down, i got rid of the oil injectors by replacing them with 14mm bolts, had a omp block off plate from 2751 engineering and got 4 pints or castrol 2 stroke oil. iv been adding an oz per gal ratio, and a whole pint to a full tank of gas, so far this is what i must say, i love it. the car runs smoother (note my s4 na has over 200k) and runs super hard and great. thanks to you guys im happy for the help. one more thing tho iv always had bad oil seals in my car since iv bought it, and from what i hear i can add brake fluid in the oil chamber to help out?

diabolical1 01-21-07 07:57 PM

never heard about putting brake fluid in oil - not sure if i'd chance that. it just sounds wrong. anyway, if you know that your oil seals are bad, then it would be most prudent to just start saving some pennies here and there for a rebuild. my opinion ....

forced inducted fd dude 01-21-07 08:39 PM

yea i am. with a grand i choose either rebuild or a jdm t2 for 850 w/o a tranny. but iv heard from ppl from car meets that its been done but not to much due to the point that the seals will get worse

forced inducted fd dude 01-26-07 12:36 AM

so does running premix work the same for t2's??

fluffysheap 01-26-07 01:53 AM

I'll join in with a dissenting opinion on why you shouldn't use premix.
* Premix lowers the octane of the fuel.
* The stock system (except 12A) injects oil directly into the rotor housing where the apex seal moves past it. Rebuilt engines sometimes show less wear on the rotor housing in the area around the injection port (implying the lubrication provided by this is better, which seems like common sense).
* The engine doesn't always need the same amount of oil mixed in, and the stock system varies the amount of oil based on driving conditions. Premix sticks you with a fixed ratio all the time.
* Measuring oil whenever you fuel up is annoying, and you might forget, or not bring your oil with you, or measure inaccurately.
* Don't put brake fluid in your oil. They probably meant automatic transmission fluid. You usually don't want to put that in your oil either.
