Did you put a bypass system on the Z?

 

Yes, as you can tell there are many opinions on the importance of a good quality clean oil filter..
I asked some of the resident experts for links to help you and all of us out but no one can produce one..

I change my synthetic oil and filter at every 7500 or so miles.. if it takes a year to get there, so be it..

You will probably get the answers you need searching the synthetic oil sites or better yet the independant testing and research sites..

Im bored with the topic now, so I think Iwill go fix myself a peanut butter and spinach taco and watch spongebob square pants..

 

Wrong.

Try this:
- Change your oil and filter (any oil and any filter)
- Drive 1,000 miles.
- Put your car up on blocks and don't drive it (throw away the key)
- Change oil filter (filter only) every week.

Your oil will still go bad.

Oil filters filter particulate matter down to micron sizes. Many of the contaminates that destroy oil are on the atomic level - gasses, acids, etc..

 

I put a bypass system on a g35 so far... Z would be the same.

Regarding that peanut butter spinach creation... how can you eat that? Although I must admit the combination sounds tempting

 

Props to G35_TX for taking the initiative and posting a good question about oil/filters @ bobistheoilguy.com..

This reply was the most relevant and to-the-point response to the original question (albeit a little facetious).

Here are my suggestions. If you plan on an ODI (oil drain interval) of:
- less than 4,000 miles, stick with a quality dino
- if you prefer 5 -7K, go with a synth blend
- longer than 7K, a good fully synthetic

Vegas and G35_TX... have you guys reviewed the discussion points of flow vs. filtration?

Filtration may not be as important as oil flow... so long as there's sufficient lubrication, an engine will work just fine. A filter that filters excellently is likely to restrict oil flow, and therefore not provide adequate oil to aid in lubrication of the moving parts; not enough oil equals increased friction and wear.

On the other hand, oil with too many unfiltered particles will also increase wear on moving parts.

I tend to side with the flow argument... I prefer not to restrict flow so typically shy away from those filters that boast micron or nano filtration. I use Purolator or Wix/Napa filters since they've have been shown to be well-constructed and provide sufficient filtration.

 

Actually, the new amsoil nano filters have no problems with flow:

Actually, if you are really interested to learn about how restrictive different brands of filters are, check out this thread:

hahaha..well we all could what if everything.. if my car is on blocks, why am I changing the filter every week, after the first change there will be no oil in the filter, unless I start it.. synthetic oil will last a year in your oil pan.. do your research.. Driving the car will produce much more "ATOMIC" level contaminates than will not driving your car..
Dont confuse the original poster any more than G35_TX and I already have

 

Well, my point is that even relatively fresh oil, once exposed to the combustion process, will start to break down. Even if you never expose it to more contaminates, and just let it sit in the oilpan, the process has already begun. Even the best oil filters cannot stop this breakdown, because it happens on a molecular level where filters have no effect.

So, to say that oil filters have EVERYTHING to do with oil life, is just not correct.

 

Well, you are correct..but I will stick to my answer when it comes to every day driving in every day life. Your filter does have everything to do with your engine life.. and oil will last a year in an oil pan, even the Amsoil web site says it can go a year or so with out being changed with no degradation of the qualities of the oil..

one question.. would you run your engine for 10k with no filter?

I wont.. I wouldnt even start my car with out a top quality filter..

 

Owned! Just kidding!

Of course not. Nor would I wait 2 years to change my oil if I only drove 1,500 miles/year.

 

ok,, 50/50 then... loolol

 

Lets see, that would depend mainly on the condition
of those tires. But had you been paying attention we
were discussing oil types and intervals of changes.

 

sounds good to me

 

yes, it'll pro-long the life of your engine cuz fresh oil is way better that synthetic oil with 3500 miles of usage. it's not necessarily needed but it'll definitely increase the life of you engine if your goal is to put as much miles on your car as possible.

i change oil on my civic every 3000, max 4000 miles since i had 25000 miles. why did i switched to synthetic on a civic? cuz i installed a turbo kit. now i have 88000 miles and everything is running smooth as it was when i bought it new.
