I remember talking to M1 tech support on the phone (can you even still do that?) and they told me they were going to phase out all the 5W and 10W oils because the 0W encompassed the spec of those oils, and they were going to market it on the improved cold start up and fuel economy, yada yada.
The public didn't understand and was frightened by the 0W designation and it was a flop, so I guess they decided if they couldn't beat Castrol they would join them. The BITOG guys can explain it...I think M1 used to be a Grp. IV, now it's a Grp. III, like the Syntec, or something like that.
But anyway, the 0W's aren't new, they had 0W-20, 0W-30, 0W-40. When they went SM they dropped the 0W-20 for a while, but it's back, that may be the green cap one you saw. |
Ha ha, I just saw an ad for the new green-cap, M1 AFE (Advanced Fuel Economy) oil. When we first discussed this (above) the M1 site said nothing about it, but after seeing the newspaper ad, I went back to the M1 site and the 0W-20 and -30 are now "AFE", so I guess Mobil finally found a marketing angle that might work for the 0W's.
