quote:You bet the Australians have emissions controls (Catalytic convertors, etc), have had this in most of their cars since the late 80's. Even Canada jumped on the emission-control bandwagon. My 1984 Ford F-150 with 302 V8 was assembled in Windsor, Ontario. It came from the factory with the wide-neck filler to accept leaded gas nozzles. No catalytic convertor, no A.I.R. pump, and there was a factory EGR blockoff plate. And it still ran like a P.O.S. Ford! Put on MSD ignition, Edelbrock intake, and Holley four barrel and it ran nice after that. The 1985 Ford's came with the fuel injected 302's and those had emissions. When you compare the sulfur levels in Europe and North America, we have WAY higher sulfur levels. The issue of lubricity is nonsense, as fuel system components made within the past +20 years have not needed the extra lubricity. Indeed, in South American countries where their crude has very high sulfur levels, the motor oil quickly becomes acidic. Next time you see your dealer, ask why the same motor in Australia needs a 20W-50? Is there a lot of "engineering" behind that one too? Jerry

quote:I'm not even sure if you can even get Mobil 1 15W-50 in Australia, except maybe in barrels. Oddly enough, you can NOT get Mobil 1 5W-50 here in North America! Cripes, you don't even NEED to worry about cold temp pumping performance, yet you have a 5W-50! Maybe we can swap? I'll trade you my 15W-50 for your 5W-50?? Just a thought ... The Toyota Australia web site goes on and on about their "wonderful" (I'm being sarcastic I guess) factory-recommended fluids. Apparently, you're supposed to use their special 10W-30 in all VVT-i motors. Otherwise, you should use the Toyota 20W-50. This isn't a synthetic. Diesel motors are supposed to use the Toyota Diesel 20W-50. At least Toyota of Australia shares all this information, the Toyota network here in North America is tight-lipped over it. Check out the URL at: http://www.partsservice.toyota.com.au Right below the picture of the Land Cruiser and Steve Irwin, click on "More" by Toyota Genuine Parts. Then click "Motor Oils Range." You will see that Toyota makes a 20W-50 JUST for their LD diesel motors. Or, if you click on "Motor Oils" you can then download an Adobe Acrobat pdf for Toyota Genuine Motor Oils. Toyota of Australia also has a Freephone number listed, so why not try it? I'm sure that Castrol and Fuchs in Australia offer a 20W-50, don't they?? Paging Doug Hillary, could Doug Hillary please answer the telephone?? Oh, I just got back today after taking another look at the Echo Hatchback at a Toyota dealer. They have a broadband Internet connection for customers to use, so I showed the Service Manager the link I posted above. Then I questioned him as to why Toyota makes us use a 5W-30 even in hot summer. His answer? "Because they make us, that's why. I don't have any say in the matter." I suggested to him that if I bought the Echo Hatchback, I'd run Mobil 1 0W-30 in cold winter and Mobil 1 Truck & SUV 5W-40 in hot summer. I showed him the Mobil product data sheets. He thought that was a great idea. I truly do think the EPA CAFE has most dealers over a barrel. Jerry
