I've read in some threads to put 1/3 in the gas tank, 1/3 in oil, and let the TB "suck" in the other 1/3. I have a 95. Can I do it through the brake booster hose? I'm at work and i can't exactly go out and look under my hood right now. Or do I gotta put it through the PVC tube? And yes, I gotta put it into the old oil before changing it.
