That would be Ford. It’s Ford and Honda that use 5W-20, I dunno if
anyone else does yet.
…at a time
when Mobil 1 didn’t have that viscosity but did sell 0W20. So unless
they put that claim on the bottle, they were going to lose sales to
the owners who were looking for 5W20.
Are you telling me that Mobil 1 was offering 0W-20 before there were
any cars that called for 5W-20? What was the intended market?
It would make more sense to me that Mobil 1 introduced the 0W-20 to
meet the 5W-20 market. After all, unusual weights are nothing new
for them; they offer 15W-50 for the 20W-50 market. But if Ford and
Honda specified 5W-20 for their cars and Mobil 1 offered 0W-20 for
those cars, why would they then introduce a 5W-20?
The reason I know this is because I was one of the folks looking for
Mobil 1 5W20 a couple of years back when younger son got his 2005
Mine’s a 2004.
BTW, it suffered a catastrophic oil-related engine failure while
under warranty. Honda had to replace the head when the cam journal
nearest the cam sprocket evidently ran dry, overheated, melted the
seal and pretty much ruined everything in the vicinity. The cam and
sprocket had turned a lovely shade of blue from the heat. The guys
at the Honda dealer couldn’t believe I hadn’t abused it somehow,
wanted to know why I would run a car with no oil in it. I had to
show them the receipts for the Mobil 1 I had been running in it.
I don’t believe it was the oil’s fault, though. I think someone
forgot to drill an oil passage, and that journal had been running
without oil since new. If so, it’s a miracle it made it 20K miles
before self-destructing. After the head replacement, the car gets
about 10% better fuel economy than it ever did during those first 20K
