What happened? Ive used it a lot of times in my car with no problems.169k on first 3.2, 169k on transmission, then 3.2 died possibly because of high mileage oil. Dont use high mileage till your over 200k. trust me i found out the hard way.
That might be true if all the mechanical parts in the engine were operated using hydraulic oil pressure, and not mechanically driven, and the oil you were using was 75W-90 gear oil or something to that affect....High Mileage oil is way more rich and thicker than regualr oil which i think screwed up the timing in the motor and the oil pump coudnt filter it enough, causing the camshafts, pistons, lifters, Valves, to run in different orders. Thats what i think. Until someone can tell me how high mileage doesnt hurt the motor, i dont know how it happend, all of a sudden it just......... died.......... right after i put the oil in.
Sounds like someone is feeding you a line of BS.Brake boosters operate off engine vacumn, they stopped using those about 20-30 yrs ago. They use Hydraulic fluid systems now. The computer for your car is a TCM [trans control module]. Most problems occur because of the Shift Solenoid which fails every few years or more,the check engine light will come on and code's in the 700's will be stored in the PCM [powertrain control module]. You must have misunderstood about the brake booster. Gotta go, LIVE LONG AND PROSPER!
Hmmm...getting to be a common issue lately... I diagnosed a bad tranny harness a few weeks ago, and discovered another bad one this week. :hmm:
