Quote from article in above URL: "This particular change is bigger than usual, but it seems that customers understand that the quality has improved."
How has it improved? I thought it was just GM had a corporate bug "up their rear" to force ZDDP levels downward due to the concern over poisoned converters??
It makes sense to blame changed conditions on price hikes. They have to make money. I can live with that. But...Is it REALLY improved over GF-3? Sounds eerily like an ex-Microsoft employee who worked in marketing.
Please, someone show me HOW GF-4 is better than GF-3.
