Well, I've said many times before that I have no brand loyalty and have boasted numerous times of the superior flow and filtration of the Amsoil foam air filters. I digress and eat my words. In order to stay neutral, I thought I would post this link to a good test I found showing all of the big boys for direct fit replacement air filters.

This is an amazing link. I think everyone should take a close look at it. I've said for years that paper filters the best and this is an excellent test which really drives the point home. I would also point out that even the paper and fibrous filters let in a fair amount of dirt which further supports the argument of using the very best oil filter you can find and changing engine oil frequently to remove as much of that ingested dirt as possible.

 

That was avery interesting study.

 

Everyone should spend some time browsing that guy's entire site. There is some very interesting (and pretty thorough!) information there about more than just air filters.

ARFF

 

so now what filter should i buy?!?!??!!?!? AHHHHHHHHhhhh **** this....im gonna go open filter.

 

The Napa Gold looked like the best flow/filtering filter.

 

As for the dirt that DOES get inside the engine, what kind of damage does it do? (i.e. if you have high silicon content in your oil... what does it to for wear/driveability/friction/etc.?)

 

This is one reason that the perceived benefit of synthetic oil is quickly negated IF you run synthetic to increase oil change intervals (this has been said numerous times on this board).

The answer to your question is to change your oil every 3k, with or without synthetic ... oh yeah and this is another reason that synthetic does not make economic sense for day to day use. Let's face it, these engines will last 250k to 300k with conventional oils. By then you're probably gonna want something new anyway.

I would rather buy a used car with conventional oil rather than one that had been run on bull sh** 87 octane fuel.

 

Ummmmmm....OK.

 

Too much for you? Do you need help understanding the comparison.

Let me guess, you are one of those guys that makes a big deal about synthetic lubricants but constantly defends some dumba** that wants to run 87 octane claiming that they get no detonation.

Just like my post said, you guys just sit around and look for someone's comment taken out of context to pick apart.... get a job.

 

I'm at work now.


Get a post count. As for arguments, not looking for one. I like my synthetic oil AND 92 octane!

Spirillis - I wouldn'ty worry about the dirt that gets past...it's really too small to matter. That's a not a very scientific answer, I know. But think of it this way, it's happening to every car on the road and probably not hurting. Don't think about it!

 

Sax, yeah I need a post count, I guess. Not looking for an argument either. I just get a little frustrated seeing how many people can bash others directly on the .org.

The amount of dirt (mostly silica) that passes through a filter is definately something to consider as far as filter selection and oil change intervals.

Carry on.

 

Actually, if you would take the time to read the UOA's here and at bobistheoilguy, you would see the great benefit of using synthetic oil for extended drain intervals. It's financially feasable to do so.

No worries, burnout. No smilies chuggin beer...

 

It is my understanding that synthetic oil protects at higher temps. than conventional. I am interested in preserving my engine, not delaying oil changes. I always have and always will use Mobil 1 and change it at 3k.

 

I use Eucalyptus Oil in my engine. Gives it a fresh minty exhaust smell and soothes my engine's sore muscles....

btw flamers, I AM joking, of course.
