How often for oil filters

Amen Brother!

Fram oil filter's have killed more engines than all the lead footed drivers combined, IMO!

I had one on a '71 Z28 LT-1 and the side split wide open about 200 yards after installing it.

Good friend put one on a new (expensive) engine that blew because of a bad filter to engine block seal, on first test drive.

IMO, worst thing you can do to your engine.

tenderfoot would be better leaving old filter on rather than installing a Fram, IMO, so I'm not going to say anything against him.:doah:
 
When I was using Wix 51794 two quart oil filters I did skip changing the filter every 3000 miles or so sometimes when I changed the oil,I figured a filter that large could go at least two changes before it even started to get "dirty"(ditto for the oil,I felt it was still "fresh" even after 3000 miles with a nice big filter to clean it)...however I never liked the thought if the old oil in the filter instantly contaminating the fresh oil none the less..

When I used stock sized filters I just threw them away every time ,always put new on,I could get a Wix 51061 at work for about $3,so why be cheap..the 51794 filters costed closer to $10 my cost because I had to order a case of 10 to get them from a warehouse,and we rarely ever sold that number,only some C60's used them factory ..

I feel its kind of a sin not to change the filter every time..especially on newer cars that have oil filters smaller than a teacup...they fill up fast with sludge..and most are located in the absolute worst spot to get at on the engine of course,which discourages even mechanics from changing one..you need special wrenches on some cars to get one off due to tight clearances..

I have told about the Wix rep doing a autopsy on other brands of filters so we could see the difference in construction and Fram always seemed to be the ones with the poorest filtration and means of securing the filter element to the shell,and had the thinnest shell too..
"Champ" filters are good filters ,they are made by Lubrifiner ,but don't cost any more than other "store brands"..
 
I owned a few ducati bikes that the manual says the filter can be changed every other oil change. Totally different set of wheels, but I've seen it said in print.
And screw fram filters, got my own failure story.
 
I'm startin to feel a little left out. Maybe I should start using Frams.

It was a hot, soggy evening. I had just changed the oil in the '78. You see it had a high flow oil pump installed a couple seasons ago and she was runnin tip top. Then, mother #*&+%*(!!!!!!!!
 
I have old Getty service station manuals that say the same thing--oil filters changed at every other oil change!..these manuals had all the mileage intervals listed for oil changes,transmission service,etc..

If anything, with the less efficient oils we had back in the 60's and leaded gas,a new filter in between oil changes as well as at every oil change may have been a better idea..
I've been amazed at how well some very sludgy engines still ran once they were taken apart to replace head gaskets or do a valve job..

I tend to think todays engines go 300,000 miles not so much because the engines themselves are better,its better & cleaner oils that keep them alive longer..that and better fuel control,they don't flood like carbs used to once in a while and dilute the oil..PVC systems helped a lot at reducing sludge too..
 
"Mobil 1™ Extended Performance oil filters provide guaranteed* protection for one year or 20,000 miles"

https://mobiloil.com/en/faq/product-faqs

It would be a real stretch to come up with a reason that you'd need to replace a 20,000 mile guaranteed oil filter every oil change if you changed your oil even at the 7500 mile interval recommended by some manufacturers. Obviously they have done something to the construction and used materials able to hold up longer than has been the norm in the past. They do caveat use of synthetic oils in them, and from what I can see, the absolute cheapest of those is double what a Wix in the same application is, so not really saving much IMO. I suppose if you were paying for premium oil, the savings might be there.

I think it's a bit of a guessing game however, on how long every oil filter can go, if there is no guarantee like Mobil has on that particular type of filter. The filter material many of them use is not super tough, if you've ever taken one apart after it's been run. I certainly don't see it being a stretch that it could come apart with age, and/or do little filtering as it ages.

When talk about it age, it's relative, do you mean age in traditional terms as 1 yr, 3 yrs, etc, or mileage age. Take a traveling business man that puts 25,000 miles a year. In theory the filter could be less then a year old and have 20 thou. on it.

I actually buy the filters mentioned by you. The mobile one filters. I don't know if they are the best or not. But I run them based off GM's computer which is roughly 10,000 miles an oil change. On my wife 15 Impala. My daily gets whatever is one special and my toys get a mobile one or wix.

Absolutely, thus why the oil change interval (and filters) are generally XXXX miles, OR 6 month maximum. Mobil has just bumped that up to 20k/1yr. For a high mileage/year vehicle, with a 5K oil change interval, that's a significant number of filters you've "saved". For a vehicle like mine that goes 7500 between changes, either in mileage or time, *personally* it's only doubling the interval for changing the filter, which doesn't really save me anything. But personal preference also comes into play.

Lol, I have owned my dump truck for like 3 years now and never changed the oil or filter. As I like say, I @tenderfoot 'ed it.
Lol I don't care about the engine whatsoever and its getting retired this year anyway. My 76 I've owned for 5 years and only did it one or twice. Once again I don't care for 350s much and don't care if they bite the big one. Always figured if the engine went it would force me to do what I want.

Couple of my cars get them too and they're changed out every time the oil is drained. Too easy, cheap and not worth the risk for those cars.
 
I did put a mobile 1 extended in and I pulled out a k&n I installed something like 3500 miles ago. It ran conventional, I should cut it open see what it looks like.

My white suburban had a tick in the engine when I bought it so I drove for 7 years/20k miles thinking it would die and I would put the big block in.
I ended up selling a few cars and needed a backup truck so I changed the oil and filter and I have been changing it once a year. Almost 10 years later and it's still going, oil pressure is lower after a few minutes of driving.
I used to change the filter every other oil change on my cars, but now I run one year for both
 
Meh....168K on my Caddy, oil changes have generally been stretched to 10-12K intervals, some times I changed the filter every time, usually every other time. Been using Walmart's SuperTech dino oil almost the entire time. That Northstar still runs great, tons of power.
 
just did a cub cadet hydrostatic trand axle filter change and someone let it go so long the filter # was no good anymore been updated for years . . . . . thats to long between changes ! :deal:

That's what I mean. I neglect them not caring. Then they can't even do me a solid by blowing up and dieing so I put in a big block. So frustrating.

Yeah if 7 years with no oil change didn't kill it I decided I am pulling it out, putting it in another k5 I have with no engine and get my big block in the suburban.
