Big Oil question

Youall will have to excuse my ignorance, but i am new to this stuff and i am trying to learn everything i can.

can someone explain to me in the simplest terms what Big Oil is?

Is it more fuel or is it more oil ? If its Oil, why are the injectors involved?

Any clarification would be greatly appreciated.

thanks guys.

Check out this thread. It doesn't go into all of the systems available but is good reading to give you the general idea. The whole 7.3 system depends on oil to run. That is why quality oil and regualar changes are so critical.

Big oil- More oil volume feeding the oil side of the injectors. The way a HEUI injector works, it takes super-high pressurized oil (500-3000psi in stock form), to act as leverage on a piston that pressurizes fuel to injection pressure. Well, when you add a chip that calls for more fuel, suddenly the oil volume needed drastically increases. Usually a stock pump cannot keep up with this volume change, so in turn the pressure begins to drop off. Before i bought Big Oil, my most agressive program would only hold 1700psi when it called for somewhere north of 2700. Now, i can hold any pressure i want, all the way up to 3850psi. Does wonders for towing torque, virtually eliminates smoke when you don't want it, increases power, and makes the truck MUCH more responsive when the power comes on so much snappier.

Has anyone done a big oil conversion and gotten better fuel mileage?

Well i do think its possible to get better fuel mileage with Big oil. . . my problem is this. . . . Whenever I drive my truck(not driving my car) I drive it like I stole it. I am rarely driving in stock form. Number two. . Big oil is so awesome for power gains that its hard not to drive it like you stole it. So i would say that my mileage has gone down because I just like to hammer down. Also. . . my mod list doesn't help the mileage at all I think. Mostly the lift and tires is probably responsible for that. But if you ask is it worth it? hell yes!

I'm sure im getting better fuel mileage. I'm not calclulating it, because i don't drive steady enough to get mileage, i do several short trips to the girl friend's house 3 miles and back during the week, on weekends we go out Hillbilly Deluxin and burn off all the condensation, but of course that's all making smoke and being fuel inefficient. Next long drive i do i will check mileage. It just has to be more efficient, logic just says so. It runs so much more cleaner with alot less smoke now.

Kris that's why I was asking. It's a lot easier for the engine to operate efficiently when it's not struggling to maintain high oil pressure. Better fuel atomization.

Thinking about it, but I need a quantifiable reason because I have no plans for anything other than stock injectors.
Probably will simply wait until this one wears out and I am looking for a good reason to spend the extra coin when the time comes.

Would big oil be any benefit to stock injectors?

Definately. I saw an improvement in driveability with better throttle response, a slight increase in peak power, and a huge increase in useable power. The power curve before was much more peaky and would fall off at higher RPM. After BO, the power just stayed strong to redline.
