It's your car and your money. Do as you like. We have just ordered a new car, and with a cost of nearly $40,000, you can bet it will be pampered. Frequent oil and filter changes are not expensive, and -whether they are needed are not - help my peace of mind.

I remember some people used to change their filter every other oil change. The filters are much smaller now days but I still wonder if changing the filter every oil change is necessary or the right thing to do. My Toyota warms up quickly, very quickly so I change the oil every 5K miles, my old pickup gets driven not much and doesn't warm up very fast. I'll change it every 3K. The old oil I pour around the house foundation, and on the wood fence. The termites have eaten the hell out of the untreated parts of the fence. They have not touched the treated wood.

There have been a lot of claims that the small particles which may increase in motor oil with time do a lot of damage, but I have never seen factual data on this. And I have searched for it. While filtering of smaller particles often does improve as the filter ages and the larger openings become blocked, I am not sure whether the loss of flow is justified by the removal of smaller particles. I have often wondered if there might be a case for installation of double oil filter units (as some remote filter adaptors provide) might be a good thing. What I THINK I KNOW, is that if you change the oil and filter regularly, it is not unrealistic to get 150,000-200,000 miles on a engine with little wear and damage. And this is what I am shooting for. Nothing can preclude catastrophic failure in an engine due to bad design, casting flaws, or weakened parts.

Quality does not prevent it from getting dirty and it is the dirty and acid that build up in oil and that cannot be filtered out that requires the change. Also most conventaion oil start to break down with a viscosity shift by 3K miles or so and if you did a flow test on you modern conventional oil after 5 K vs new you would likely be surprized and rethink this whole thing. New engine are harder on oil than ever these days. ----------------- TheSnoMan.com

You need to read what is truly severe service. Jiffy Lube et al would like to convince you that starting the car up and moving it out of the driveway is severe service. Ford (and other manufacturers) have tried to be more exact in order to dispell this misinformation spewed out by the oil change industry. For a 2007 Ford Fusion, Ford has the following say about "Special Operating Conditions;" ----- "Items Needing Special Attention "If you operate your Ford/Lincoln/Mercury primarily in one of the more demanding "Special Operating Conditions" listed below, you will need to have some items maintained more frequently. If you only occasionally operate your vehicle under these conditions, it is not necessary to perform the additional maintenance. For specific recommendations, see your dealership service advisor or qualified service professional." ----- 3000 mile oil changes are recommeneded for the following "Special Operating Conditions" (refer to the above statement - occasional operation in one of these condition does not make it necessary to decrease the oil change interval): * Towing a trailer or using a camper or car-top carrier * Extensive idling and/or low-speed driving for long distances as in heavy commercial use such as delivery, taxi, patrol car, or livery * Operating in dusty conditions such as unpaved or dusty roads * Off-road operation * Use of E85 50% of the time or greater (flex fuel vehicles only) Again, these conditions only apply if you operate your car "primarily" in one of these conditions. Most people aren't towing something "most of the time," most people aren't using their cars for Pizza delivery most of the time, most people don't operate their cars on dusty roads most of the time, or off road most of the time. Clearly Ford is trying to walk a fine line. They are trying to counteract the Jiffy Lube 3000 mile oil change propoganda for average drivers without giving free rein to people who actually do need to more frequently change their oil. Ed |
