Yeah, I like it, too. Great line.

My psychological limit is somewhere around 5-6k miles or 1 year, but that's mainly because I don't drive much. If I did a lot of hwy driving, I'd probably extend it further.

Lets wait a second here and look at the hundreds of used oil analysis posted .Unless there is a mechanical problem are there any used oil analysis that there is a problem with due to the oils not holding up? Not an opinion but fact study up the used oil analysis postings.

Wix like most filters can go to 10,000 miles with a quality synthetic.

Lots of good information on why one should raise their OCI. That is why I originally came to BITOG and threads like this are how I came to the conclusion (and now practice) a 10K mile OCI would work fine for me. After two used oil analysis of my own and looking at many from other people on here I am convinced that changing your before 5K miles is usually a waste of money.

FYI FastSUV, as best I can tell, Honda started recommending a 6K mile OCI for their Accord in 1986.

Contaminate load is what keeps me changing the oil in <5,000 mile intervals even though I'm sure the oil itself is good to 20,000+. I do, however, reuse the EAO filters for 3 OCIs.

How do you re-use EAO filters ? Did you leave it in or removed and drained then put it back on ?

I dealt with that limit for years. Still recovering, since coming to BITOG.

WIX filters are in the top 10% of all filters I'd say...they filter well but not "too well" like Purolator Pure-One does LOL.

WIX premium filters use silicone anti-drain back valves instead of nirile and they have metal media cups instead of [censored] cardboard like Fram.

If I were to go over 7500k, I'd use a Mobil 1 filter, but for the average Joe WIX is about the best you can buy at a parts store every day

LOL...never heard it that ay before; but makes sense LOL

"psychological limit"

I myself struggle with this issue and I am up to 4k now on one vehicle wit blend and am considering 5k

But my dad had the oil changed on his '95 Grand Cherokee w/ dino every 7500 and it began using up to 2qts of oil between changes when it hit HM...I BET if he dealership had been doing it every 3-4k, then this would not have happend...

u know what they say "maintenance is the key"

Ooooohhh! You are about to get in big trouble from Bill. I dared to comment once on Fram, and I was called out in a heartbeat.

Remember, this forum is open to comments and opinions, unless they are critical towards Fram. Beware!

I'll admit I'm still a tiny bit skeptical of long oil changes, but the first two oil changes happened at 10,040 miles and 19,350 miles going by the OLM on my CR-V. I do change the filter at every change, contrary to what Honda suggests, and I use Syntec. It hasn't used any noticeable amount of oil yet, even though some folks say the K24 does use some oil.

 

[chaser06]

To me changing oil every 3k is a waste unless that's all you drive a year.

Conventional 5-7k
Synthetic 10-12k

I change my oil when my maintenance minder indicates. That's usually aound 10k because of all the highway miles I drive (80-90%). used oil analysis have indicated that my oil still has some life left at that interval.

I currently run synthetic but some here have proposed that I could use dino based upon my driving (and there are some used oil analysis that back that up).

If you really want to fine tune you OCI's do a series of oil analysis.

 

[RedByrd]

I like to go for around 5000 using a synblend.

This is the first the car has been run on synthetics (used car) and I figure it needs a shorter interval for a while.

To me, a good filter is just as important as the oil, especially the longer you go. IMO Wix makes the best on the market in terms of cost value, with Purolator second (they seem to be "cheaper" now than a while back).

So what I am getting is that the 3K OCI was just an old recommendation that people got used to and have been brainwashed to believe. I think I am gonna just run 2 ARX cycles and then use a WIX and try to do 5 or 6K---dang--it's gonna be like going through oil change withdrawal... I don't know if I will be able to do it. Maybe my 05 durango with 105K miles, but the 311K mile accord might cause me to relapse....

Hang in there... It's hard but it will pass. Call on us BITOG-er's if you're feeling weak at any point!

Buy yourself other equipment (lawnmowers, weed eaters, leaf blowers, etc.) on which you can start changing oil in order to scratch the itch.

 

[Spector]

A lot is in the genes (how good is the basic design to begin with) , because one engine started using oil at HM due to 7500 OCIs is not really a good indicator nor would one that was changed every 3000 and never used oil either.

My Camry just turned 200,000, used Amsoil every 7500 until 150,000 when it developed a head gasket leak that was not worth fixing. leaks/consumes a quart every 1500-2000 miles and has been that way since 150,000 miles. Still runs great though, using Maxlife.

As to filters, on another vehicle (as I noted many times in this forum) it went two 12,000 mile OCI intervals, GM 3800 Series II SC, the first changing the filter half way through and the second no filter change for the entire 12,000 miles. The used oil analysis was the same, it did not make any difference and both filters upon cutting them open looked the same to the naked eye. These were the ole Amsoil pre Donaldson filters, not the new design.

 

[Ken2]

My Volvo turbo has 166k and gets 10,000 mile oil drain interval with Schaeffer syn-blend oil an one Mann filter. The last report said that the oil was still good for continued service. My Tundra with 65k has the same oil that still looks clean on the dipstick at 10k with one Denso filter.

Oil does "wear out" due to oxidation of the oil, depletion of the additives, and shearing of cheap viscosity index improvers. Better oil has better ingredients to live longer. Most of the "dirt" in the oil of a tight engine is due to breakdown of these oil components, not other contamination.

I'd only recommend 3k ODI if either the engine was really worn with lots of blowby or if the driving was just a few short trips where the engine never got normally hot.
