Alright I took the plunge. I have added it to the brake booster (letting it set for a bit as I type this) and added like half a can to the oil. I have a valve that loves to tick when the engine is cold so I figured what the hell. I will post back if I see any difference. I did not put a lot into the booster line, maybe like 1/3 of the can. It is dark out so we will see if I can see any smoke.
And yes I have a little left in the can so my fractions are fairly accurate haha.
AFTER: Well it does seem to have helped. I did not get a whole lot of smoke, but then again it is dark, and my exhaust ends before the rear axle, so it was tough to tell from the driver seat. However the engine feels more free i guess you could say. Does not need as much throttle input, and it does seem to run smoother through the power band. I must say I had my doubts, but with nearly 215k on her, I can only imagine what it must look like on the inside. As for adding it to the oil, I doubt it will fix my lifter, and I wont know until tomorrow morning anyways.
