This one is for Woody
Hey Woody, had to ask the Wife, the D? Dilithium crystals! Oh! of course! Anyways, study the pic, a hint, NCC-1701. Plan for the day is as follows, get the Turd out of way, slip the Wifes Cobalt in the One car garage and change its' oil, waited a long time (Cruiser in the way) 12000 miles on Mobil 1 extended, not worried a bit, just that darned change oil message, new cars! Think about it, what do you do? reset? Hate all that computer, winey junk, like people can't look at their fuel gage or pay attention to their oil mileage anymore. roll the Cruiser in there, investigate temp issue, set timing, run it up 2000 rpm for 20 min., set valves hot, brake and clutch fluids again and finally, dile in the carb. Sounds good right? Best made plans of mice and men. I'll try to write all of this cronologically, suffice to say it has a happy ending. So back to the picture, Valvoline racing grade, you bet! trust me on that one, back in Engineering school, we watched as the test pan increased in temp, pennzoil smoked first, then the cheap stuff and at more than twice the temp of the rest...you guessed it the big V. What you've heard is MARKETING, not fact. PENN sucks. The vacuum bleeder, some clutch hydros are almost impossible without one, no more waiting for your buddy to come over to get er done. The forced pressure, isolated bladder types are the best though. let me see, ah the filter, says SAE, thats Society of Automotive Engineers rated best, they should know, their the ones who set the standards that allow you to drive your car for 3000 miles an oil change and still get the miles on the motor. Think they fall for the marketing pixey dust?
