Toyota tells me when to change my oil. THEY are the authority, in my case, because they warranty my engine. |

On the other hand, changing the oil yourself will significantly cut down on other needed repairs to your vehicle because it eliminates the opportunity for other hands to cause problems. |

I like my mom's Buick, the computer tells her when to get the oil changed. It didn't tell her to get the manifold gasket changed that started leaking but I'm sure GM is working on a sensor for that. |

That may be the case for normal driving condition. Most people drive in severe conditions. |

Pretty sure he was directing the original post at the people that go far beyond the manufacturer's recommendations. Believe it or not, there are still some people out there doing two to three times the number of oil changes that the manufacturer recommends (i.e. 3000 mile oil changes) because they don't understand that excessive oil changes provide no additional benefit (and may actually be bad for the vehicle). I've never met one of these people in real life, but I've read their postings so they probably exist (maybe they are only in states that lack good public schools). If 3000 mile oil changes are "cheap insurance" why aren't they changing the oil every 1500 miles or every 750 miles, and buying as much of that cheap insurance as they can get? |
