Fair comment.
However in my area, users are going back and complaining of clatter at startup. The men in white just say..." Its normal"
Well its not normal.
VW dealers are telling customers that it is normal to burn 1 litre of oil per 1000 kilometers. In my opinion this is not normal and is outright fraud. Well maybe thats not the right word. But disgraceful anyway.
Actually, you'd be surprised how many car owners accept the "it's normal" bull s***:
- it's "normal" for a car to make that tickticktick noise
- it's "normal" for a car to burn more than 1 qt every 1,000 miles
As long as most people blindly accept what EPA CAFE and the dealer try to pull off, what can you do??
True, you won't have too many cars/trucks exploding just from running the xW-20 oils. But long-term does raise questions.
Anyway, if the xW-20's are so good, then why doesn't Ford recommend it in Europe. Or Honda for that matter?? Their idea of a "thin" oil is a 5W-30, and the viscosity charts include 15W-40, 15W-50, and 20W-50.
It can't be because of poor fuel, as the Europeans got the sulfur out a LONG time ago. You would think with fuel being 3X-4X more expensive than here, the Europeans would jump at a theoretical 0.6% "gain" in fuel economy.
Unless they know something we don't.
I'm old enough to remember when 5W-20 oils were used for winter. My 1984 Ford shop manaul also had the warning "Not for temperatures over +50 F or for sustained high-speed driving."
I don't "bash" thin oils. Due to my severe cold winters, I run Mobil 1 0W-30. My 2000 GMC Sierra with Vortec 5.3 also burns more oil: 1 qt every 4,200 miles vs 0 qt every +7,000 miles with Mobil 1 15W-50 in summer. And that's pulling a heavy trailer +7,000 miles.
