Since you are the local Oil expert, what interval do you change your oil at?

 

Good read.

 

Very interesting reading. Thanks for the link

 

Another "thank you" for the link. I'll forward the link on to the student environmental club here at my University.

 

I am not disagreeing but balance this out with today's reality dealing with auto manufacturers.

There were several years of problems some Toyota owners had with engine life that was blamed on lack of oil changes (it was eventually pinned on engine cooling deficiencies), and the numerous warranty denials that state in whole or part it was owner negligence for not following the maintenance schedule.

The oil companies are not motivated to do something to cut their own sales so the initiative (actually the control) of the situation is with the auto manufacturers. Look in the S2000 manual and see where usage of many cars specify changes every 3750.

Anyone leaning on the oil companies in this campaign is missing the major issues driving change intervals.

 

I would love to see some statistics on how much oil is released into the environment without treatment versus the amount of oil recycled. The article focused on untreated oil, which is a significant environmental risk. However, I would venture to guess that almost all oil changed these days is recycled.

I believe that most facilities which provide oil change services are required to recycle oil. And used oil recycling has been available to those who change their own oil for over 30 years. It would seem to me that those who are most likely to not recycle oil are individuals who do not want to bother to take the oil to the local service station or recycling facility.

 

My Accord (2004) recommends changes ever 10k, with severe being every 5k. I changed mine at about 6k, and the friggin' place put in a synthetic blend.

Now I understand the logic of running synthetic in a 9000 rpm S2000, but this is a 6500 rpm Accord, and I think it has only hit that redline ONCE in it's 6000 miles! It was broken in properly, etc. I wanted to do the first change and get it out of the way, but I think from here on out I will change it every 7500 or so.

Anyone think I should change filters more often than that?
