Oil filter
Ok, i dont now if anyone else has heard this. But i had a Fram (oil filter company) representative tell me that if an oil filter is changed every other oil change that its accually better for the car, although the company will never publicly admit it (for obvious reasons). I think its complete bull****, although it did come from a representative. What do you all think?

Just because you're in school for "automotive" doesn't mean you can't learn.
I have Nissan master techs call me weekly asking about 3rd gen problems... and you'd think I would be learning from them!

change your filter twice as often as the oil itself

From what I read in the Fluid section, certain oils can last a good deal if the filter is changed at a certain time, you'll just have to fill up the oil that you lost when changing the filter.I don't follow that rule though, as I change mine every 5,000miles oil/filter

Of coures they do. That way your cars engine will wear out faster= You buying cars more often...

Having hte car wear out faster has nothing to do with it at all. Since most of our cars were built, the refining process of crude oil has increased dramatically and the resulting engine oils are much better. It's the better oils which are why manufacturers are recommending the 3000mi oil change can be pushed to 5000-7000mi, not the fact they want the cars to wear out faster. If they wanted cars to wear out, they just make crappier cars. Since when has a crappier product helped a manufacturer? All of the top selling cars out there generally have good reliability and build quality.

I disagree 100%. Quality of oils has not gone up greatly. It's the quality of the ENGINES that have gone up greatly. Greatly improved engine design, greatly reduced blowby, more efficent head design all leads to greatly reduced oil contamination. thus longer change intervals.

Oil specifications are getting tighter and more is being demanded of oils, particularly synthetics. Conventional oils are being made out of better base stocks and have better additive packages to meet these specs. Some are being made out of base stocks that are getting closer to the level of synthetic base stocks.At the same time, engines are getting cleaner and made to tighter tolerances, which is easier on oil. Many newer cars like my parents' new Mazda don't even specify a break-in period or tell you to change the oil within a few hundred miles anymore. Combine a carefully constructed engine with durable synthetic oil, and you get those crazy sounding 10,000 mile oil change intervals some cars specify now.... mind you some of those particular cars have fairly high oil capacities.

Think about this. Compare oil quality from 1985 to 1995. Now compare Nissan's 3.0 V6 from 1985 to 1995. Which do you think has advanced more?
