pre mix

[therex]

just curious, what kind of pre mix is everyone using?

[NYCGPS]

Idemitsu.

Whatever is cheapest of the name brands minus the generic crap like the WalMart house brand...
Right now that's Pennzoil from KMart @ $22 / gallon.
With the prices all over $5 / quart, it's getting expensive!
I used to love the good 'ole days when this stuff was under $3 / quart.

alright i was leaning towards penzoil, ive heard valvoline/castrol were watered down a bunch?

and how much does everyone add per gallon of gas?

[RETed]

I was using Valvoline Multi-Use exclusively, until it started to climb over $6 / quart.
We've used Castro too with good results.
As long as it has the TC-W3 rating, it's good to go.
Yeah, the viscosity is a little different between the brands, but our teardowns show good wear.
We've run race motors (NA) with mostly Valvoline Multi-Use upping the ratio to 50:1 - 75:1 with good teardowns.

I normally just add half a quart (16 oz.) to a fill-up - 1987 Turbo II - which normally comes out to about 12 - 13 gallons, and the ratio comes out to right about 100:1.
For S5's with the bigger fuel tanks, if you do this, the ratio comes to just about 120:1 - 130:1.

ok cool and sounds good, last question, since my oil metering pump is deleted, can i use start using synthetic?

I mix cheapo Wal Mart TCW3 oil in my non injected motor, I also use synthetic motor oil.

Of course.

I've been using what ever is available at wallmart, mostly penzoil 16oz bottles. Those are easy to carry around (while they are sealed), and I normally do a full penzoil bottle to a full tank which like Ted said its comething like 125:1 (I just avg the numbers)

[therex]

alright cool thank you everyone for your input, really appreciated!!

[Sm1nts2escape]

Klotz here as well. Use it for anything that requires pre-mix.

What about using an adapter on the omp, what type of oil would you recommend?

Same stuff - you would still use a TCW3 rated lube, but with the OMP adapter installed, you no longer need to mess with mixing it with the gasoline at every fuel fill up. Just dump it in your OMP adapter's oil tank that you fabricated, and top off the tank when needed.

I sometimes wonder if pre mixing in the tank lubricates better than the OMP adapter. Not sure if its a myth, or not. I am kind of tired of pre mixing every time I fill the tank up lol

I heard it maybe harder on the fuel injectors when you premix they aren't designed to use premix. also when you engine brake there is no fuel going to the motor, and if you premix there is also no oil going to the motor.
