^lol...
To add to the original post, I absolutely think the 0W20 syn can go the 10k intervals. Whether people follow the recommendations and/or like them is a different story entirely. But if someone were to switch back to dino and run more normal intervals (5k), I'm sure that would be fine as well.
If Toyota and other companies can successfully educate the public and their customers, then they wouldn't feel slighted at the higher cost oil due to longer service interval and less inconvenience of frequent servicing. Plus, they can still choose any mechanic / service shop of their choice and put any brand syn 0W20 of their choice (unlike the more difficult and restrictive VW 505 garbage like someone else mentioned for example).
Sorry, I can't resist
To add to ARCO's ramblings... My brother purchased his first car in 2005, a 2003 Toyota Matrix XR with the base 1.8L 1ZZFE. This is also our first Toyota product (and second Japanese car - previously all domestic, and still do have domestics in the family). While it is a good little car, and continues to serve him well, it is not without issues. It began burning a lot of oil at about 90,000 km. A compression test revealed that 3 cylinders had low compression, and 1 very low. Bad rings. Previous owner had all oil changes documented and were done on time. Engine ran great and burned very little oil when we bought it. It now burns 1 qt per 1000 miles, sometimes more, sometimes less. The recirc door servo broke, the blower motor resistor was toast, there are numerous creaks and rattles, the wiper motor is about to kick the bucket, his front wheel bearing is nearing the end of its life, the idler pulley needs replacement, the A/C is not very cold, his gas mileage is not always very good (sometimes great though), and I have an educated hunch that one of his transmission shaft bearings is worn (5 M/T).
I have no doubt that this car will continue to run just fine for years to come, despite its issues. No, Toyota is not perfect. They aren't the perfect cars that most people think they are. They're just like everything else out there! Sometimes you get lucky, sometimes you don't.
My mother's Chevy Venture that has had nothing but horribly short trips, towing trailers, loading up with heavy junk, and being used and abused daily, now has 215,000 km and the ONLY problem we've had with it is those stupid intake manifold gaskets. It's an 02 btw. I'm sure many can say the opposite about their GM's.
No need for the bashing to continue, and on with the 10k 0W20 syn discussion
