I own an '04 Pontiac Grand Prix w/ 48,000 miles on it. I do my own oil changes w/ Castrol GTX or Mobil 1 5W-30 and a FRAM oil filter. For the first time, I added Lucas Oil Stabilizer (4 quarts oil and the LOS), and my has begun to shake when first started in the morning and sometimes throughout the day when I've been idiling for more than a couple of minutes. I'm going to change the oil again here soon, but if anyone has any reasoning as to why she's shaking after the stabilizer was put in, it would be greatly appreciated! I wrench on cars in my spare time, so I know my stuff ---- therefore, details would be great. Extras: fuel injectors are fine (also run fuel injector cleaner ever 3rd month to keep clean), just cleaned my throttle body and mass air flow sensor few weeks ago, and there is a new air filter. I usually run 87 (b/c she is a regular 3.8 V6 non-supercharged) and once a month put in 89 or higher (75%, I use Shell). Thanks for the help!
