i thought you were saying ask the dealership about what filter to get, sorry bro.

I am running Mobil 1 and still do 3,000 mile changes. If you are using the stock size oil filter...it's pretty tiny, so I wouldn't trust it for more than 4,500 miles with synthetic. (I am using the Mobil 1 filter as well). Anyways, this is a very subjective topic, and everyone has his/her own opinion.

i run the v6 filter for a 626

I run 10w30 Amsoil and genuine Mazda oil Filters. I change my filter every 2K and full syn oil change every 8k........Duncan

Where's your evidence that you need to change synthetic by, or before, 5,000 miles? Or is this just your opinion. Big difference there...

The synthetic oil itself might last many thousands of miles and possibly continue to lubricate well, however all the dirt and muck accumulated is still there. Just because it is synthetic doesn't necessarily mean it should perform for an extensive length of time. Getting the dirt out more often would seem much better for the engine, as there are less particles to cause wear.

I'll as you again, where's your evidence? Take a trip to www.maxima.org Look for their oil analysis spreadsheet. There are folks going 10-15k on synthetic and a FACTORY Nissan oil filter with no problems what so ever.

I just don't like when people spread ideas they heard from their friends dads, cousins, grandfathers brother. There is nothing wrong with running synthetic oil in your car for 10k and a factory filter. Where's my evidence? Again, take a trip to www.maxima.org. I contributed to the study with my SE-R. 10k and a Nissan filter and I still was well within tolerance.

I am not doubting you, I'm just saying that I change it earlier because earlier can't hurt. Also, Nissan makes different engines and filters than Mazda does. Oil grades, brands, changes, etc. are all very subjective like I said before. People each have their own preference.

Buddy, do some reading, find out what your oil is doing during an engine cycle, and why we use oil filters and why we change them. You can easily go 25K on standard oil without any problems, but we are talking damage being caused by dirt being circulated through a dirty clogged filter, and through every engine component. Oil full of crap, that should have been changed a month ago, depositing crap all over the engine, and not picking up the new crap. Long term dammage.

There is no evidence, I can tell you every mechanic I have ever know has said, 'do an oil change before 3K, even synthetic, and use a good filter.' Is that eveidence, no its hear-say.

Ever hear of a person with the wrong air filter, or no air filter on their car. The first thing the mechanic will do is an oil change to eliminate all the accumilated debrit in the engine. That tells you something.

I think that 'duncanslx' is doing it right, changing the filter between oil changes. Though, I would save the money on synthetic, and get a good FRAM, or something, filter.

Do what you want, believe what you want. These are automatove FACTS.

1.Synthetic oil is to be changed as conventional oil does, 3000 miles or every 3 months.

2.We change the oil and filter, not just because the old oil has broken down, but to remove the debret collected by the oil and oil filter.

3. The filter is the most important part of the oil circulating system. Hello it does the 'filtering.'

4. Ask any mechanic, shop owner, service or parts advisor, at any dealership, in any part of the WORLD, "What is the one thing I should do as far a vehicle maintenence?" They will all say, "Do an oil and filter change every 3000mile, 5000KM or 3 months." They don't say, "Do an oil and filter change every 3000mile, 5000KM or 3 months, unless you use synthetic."

5. Synthetic does not break down as quickly or as easily as conventional oil, but that is not why we do oil changes. Look into it buddy.

Hey n00b, you just discredited yourself with that statement. "Good" and "Fram" should never be in the same sentence together. As you would say, look into it buddy.

duncanslx

I would just use Mazda Genuine filters. Again, opinions are just that. Whos got proof that Fram does not make a good filter? And for that fact, who the hell considers wire loom to be an engine mod?.............Duncan

Myk

Whats wrong with Fram?

I'm not saying I know its good or not, Its the first name that popped into my head.

Does Fram have a bad rep?

I don't want to look into it, you tell me!!!

walight01

do a search and there is a company that took dozens of oil filters and did thest on them, and they said that the old fram filters were pretty good, but they are crap now compared to the rest of the filters, even the 2 buck walmart brand. but they didn't say that it couldn't do the job.

Here is what you all need to read:Oil Filter Study

And by the way, it is not a FACT that changing your oil every 3000 miles is best for your car. Changing it every 100 miles is best. Or every other day would be great. The 3000 mile thing was created by the Oil industry to sell you oil. I had an '83 Scirocco that had it's oil changed every 7500m with dino and it had 265,000 miles on it when I sold it and it started up and ran like new every day. Now with my P5 I run Amsoil and change it every 7500m like it says in the manual and I'm sure it will do the same. But go ahead and do it every 2 or 3k if it makes you feel better, it can't hurt.

02 Honda Civic, 01 Mazda Protege,00 Ford Focus

All these cars say 5000miles and Honda recommends that no sooner then 5000miles as its a waste of money

3000miles(5000kms) is to soon!

Then again I don't keep my cars for 5 million miles

Honda In Pembroke has a Car used by a Lady who delivers the Auto trader and does 8000kms (5000miles) every 2 weeks and odes the recommended 8000km oil and filter change. She has over 400 000kms on her original engine. I am in no way promoting HONDA here , its just one of the few pieces of evidence as most New cars recommend 8000km intervals and they have not had time to put 400 000kms on these new engines ! Except Auto trader Lady!
