Picked up this 10th gen Impala with 80K miles and the oil has been religiously changed at 5-7K miles with synthetic Dexos 5W-30 but varying brands.
Engine has no noises even when starting cold, very quiet and doesn't leak.
I would like to go with a single brand, either Amsoil, Mobil1, or Redline, open to other suggestions.
I plan on keeping this vehicle for awhile as it's in near pristine shape.
Trans fluid was also replaced at 45K which was nice to see.
My first GM 3.6, so curious to what others have used.
