Changing oil filters

Probably no reason

Cheap insurance

Get every extra quart of old oil out

Some may say paper element degrades

Maybe others will have more concrete scientific reasons

It’s all voodoo and speculation. Only purpose when driving little is to maintain resale value imo

 

While 2000 is probably right, voodoo, what are you saving/winning by not changing it? Seriously? The filter is cheap.

 

i change my filter every 6000 miles. Regardless of time. be it 2 years, 3 years.

 

I have seen filter media fail that have been in service for a long time. While rare, it isn't worth the risk to me. I probably wouldn't have a big issue if you replaced the filter every other year, with annual oil changes...that seems reasonable.

 

Why not? It's only $40 bucks or so..

 

30 minutes to unscrew an oil filter and then screw another one back on? Ummm… it takes anyone with the filter wrench or hands 1 to 2. It's *literally* like changing a lightbulb.

If it's too much trouble to unscrew a filter and then screw a new one back in I got nothing for you... you probably shouldn't be servicing your car if it takes that long and you have more "productive" things to do. I don't know but to me lubrication of a highly stressed racing engine ranks as an "important" thing not sure what "productive" things out rank it..

 

1. Place filter socket atop filter from above.
2. Take 12" 3/8 extension and place into filter socket and turn counter clockwise with a wrench
3. finish unscrewing filter and then tilt to the to right with left hand, reach under A-frame with right hand and remove.
4. Replace in opposite order.
5. Ask question on Ferrari chat to try to justify why shouldn't be done
6. Shake head at Ferrari owners why they have the reputation that they do....

 

Nope.. a Yugo. I use a sledge hammer for oil filter removal and one of these...

Those filter socket wrench five in a kit from Harbor Freight don’t fit the 430 filter.

 

Just my 2 cents - the change your oil/filter every year is a myth.
General exotic public/service centers says the same thing over and over, has to be changed every year because of water/acid content - which is typically vapored off after oil has reached temp. for a given amount of time.

 

Timely comment Todd. I was reading an interview online of the owner of Blackstone Labs that does oil analysis, and he was asked about the necessity of changing oil annually in a car driven few miles and he said their testing shows unnecessary. He didn't give a guideline to what is recommended, but said annual oil changes is not required when a car is lightly driven. None of this would apply to coolant or brake fluid of course.

 

Got the same story from them .. and I believe them

I’ve seen rust formed on the inside area of the pot metal on a filter that sat for a couple years with fresh oil and no engine start. (Airplane)
Fwiw

 

Blackstone did a lot of testing for for me, concerning my product, and does some of my oil analysis along with ALS, I have a few posts on this issue in other threads. Have a classified sponsor ad so have to be careful with what I say in here.
Very surprised that all the chat room "experts" are not all over this thread.

 

Despite my protestations... To each his own. It’s your car be it timing belts or oil changes. Studies showed that mammograms could be done every 5 years with the same statistical outcome. The problem is, a life and an abstract statistical outcome are different... esp when it’s your life.

As with your car... do what you want and do what I want with mine. When it comes to my wallet, unless others will put their money where their mouth is, I could care less... Don’t complain when “it’s priced in” when you sell it....

 

An interesting question, and I don't have a technical answer. Hopefully there will be more responses to the question that was actually raised.

 

I couldn't imagine not changing the filter when I change the oil in my cars. Period. If you've got a good enough reason to change the oil it follows that the filter should go with it. Having said that, my grandfather didn't believe in changing oil at all. He just changed the filter regularly, which made me cringe. He'd say, " It's still oil ain't it." It seemed to work for him, he was happy to add oil as necessary to his vehicles. When I tried to tell he's causing premature wear he'd shrug his shoulders and say, "We'll see who's bought the most oil at the end of the day."

 

FWIW, back then (20y ago), filter was changed every other oil change in France... This was the norm. And I'm talking non-exotics. I wasn't privy to the F-world at the time ;-)

 

I don't get it....$100,000 cars or more and leave a paper filter instead of replace? Filter's clog too...does it have a bypass if it clogs?...$30,000 engine over a $40 filter...really? are we debating this? I appreciate everyone's opinions and research but I choose Curt's attitude and change it...period.

 

$ wasn't the question. No one is debating $, but everyone who keeps pointing it out can't seem to let it go. IMO it was a simple technical question. Why can't people stick to what was asked rather than injecting opinion on a point that the OP never brought up.

Does your oil look dirty after 1000-1500mi, to the point where it would result in any significant restriction in the filter media?
