Re: 2003 Accord Oil Change, once a year?
Consumer Reports did a scientific study on changing oil a few years ago.
They studied taxi cabs in NYC. They even took the engines apart to check for wear and tear, and they compared name brand oils to no-name brands. Their results were surprising. Frequent oil changes, or synthetic oils made little difference to performance or engine wear! Also, there were no significant differences between no-name brand oils and heavily advertised name brands. Finally, the only time frequent oil changes are really necessary--more than once a year-- is if you live in places with extreme climate changes such as Alaska, etc. It seems to me that the oil & automobile industry drives this panacea for frequent oil changes. Save your money and the environment and change your oil once a year!

The taxi cabs are never shut down except for maintenance,and run 24/7 ,there by maintaining constant engine temperature so that no acids and h2o can develop in the engine oil. A more comprehensive and true test would have been to use commuter cars that are started up twice a day in all kinds of weather , winter and summer and then come back with a report. We all know that 95% of engine wear occurs on COLD start-up. and by cold I mean as cold as -30*F here in sourthern Ontario, in the winter. This would have been a much more honest test of everyday driving conditions. I consider the Consumers Report Test on taxi cabs to be nothing more than smoke and mirrors, for whatever reason. ed/ontario |

Nonsense. Although many cabs run 14-16 hours per day, virtually no one drives 24/7, even cabbies in NYC. Use a bit of common sense. Nor were they doing so for the Consumer Reports testing. This test was not flawed, by the way. It didn't test or address every aspect of lubrication and maintenance, but it wasn't intended to. > A more comprehensive and true test would have been to use commuter cars that > are started up twice a day in all kinds of weather , winter and summer and > then come back with a report. And people would have pointed out that stop-and-go traffic is very hard on engines and would make a better test. Not necessarily so, of course. The cars were not run 24/7, but were used by actually cabbies in the execution of their normal duties. I do not recall the time frame of the test, but it seems to me that it covered at least 50,000 miles. This would quite possibly have included a fair variety of weather patterns. > We all know that 95% of engine wear occurs on COLD start-up. and by cold I > mean as cold as -30*F here in sourthern Ontario, in the winter.

Not for cabbies. For me, for example, a different test would have been more applicable, as I drive 80 miles each way to work, each day. Not the stress and strain of starting and stopping, sudden acceleration and braking of the cabs, but also not the 5 mile trip to the office. Again, the test was not comprehensive.

Re: 2003 Accord Oil Change, once a year?
Let's set the record straight! I will quote extensively from Consumer
Reports of July 1996, "The surprising Truth about motor oils": "Modern motor oils needn't be changed as often as oils did years ago. . . Even in the severe driving conditions that a NYC taxi endures, we noted no benefit from changing the oil Every 3000 miles rather than every 6000 miles. . . we don't recommend leaving any oil, synthetic or regular, in an engine for 12,000 miles, because an accumulation contaminants-solids, acids, fuels, and water-could eventually harm the engine." I think the study is scientifically accurate, and Consumer Reports went to great lengths to do the tests-after all, their credibility is at stake! This is what they did: ". . .For consistency, we used only 1992-93 Chevrolet Caprice Cabs. Each received a precisely rebuilt 4.3 liter V6 at the beginning of its 60000 mile test. . .a local shop completely machined each engine block and crankshaft, rebuilt the cylinder heads, and installed new bearings, pistons, rings seals, gaskets and oil pump. . .Over the next 22 months, our engineers paid more than 100 calls. . .they dropped off test oils and picked up used-oil samples for ongoing analysis. They also made sure the oil was being added to the engines when necessary and changed as scheduled. After the 60,000-mile test, we remeasured the key engine parts. We also examined combustion-chamber deposits, the color of valves, scoring cylinder walls, and valve deck deposits for any sign of engine problems." Wake up consumers, no one else has done an extensive study like this! Oil companies , garages and auto manufacturers couldn't care less! I know many mechanics that didn't even know of the study or even cared to read it. They're still caught up in oldwives tales. It's time to rethink this! As a consumer you have a right to protect your pocketbook against unscrupulous oil manufactures, oil retailers, garages, etc. The truth is out there! Go seek it!
