Oil change by mileage? Or by oil life %?

The guys that run super expensive oil and change it every 3000 miles because its "cheap insurance" know nothing. 

Really?

Everyone can do what they want with their money and vehicles IMO.

It's not my place to bash them if they do things different than I do.

Jacob. You trust too much in what man says.
Again.

If you cant trust man how can you trust man made things?

It is well known that the oil companies and automotive industry are in cahoots. Why should anyone trust two entities that knowingly will lead you astray? Do what you want but do not say people who wish to be smart about where they invest their $$,$$$$ dont know anything. It just means they are more diligent then those who follow whats said on a bottle.

Be a leader not a follower.

Success is in the eye of the beholder right?
Then ignorance is in the head. As we will never know everything in life until we learn and believe what we learn.

notice the post where a guy ended up with lifter tick? No coincident there...

I don't even know where to begin with this.  Is this some sort of pep talk?  Are you trying to make this a teaching moment?

 

Buying Amsoil or any other premium synthetic oil and using it for 3000 miles then changing it is not an investment.  Its the complete opposite of that as in its a waste.  There isn't an Amsoil salesman out there that will tell you to change the stuff every 3000 miles.  While they'll gladly take your money, behind your back theyre probably saying the same thing as me.  There isn't an oil analysis lab out there will tell you Amsoil or other premiums are only good for 3000 miles and that should be your change intervals.  I don't care what anybody spends their money on (you know Im right but you have to bring up the other peoples money thing to make yourself think you have a valid argument) but I have every right to say if that's what theyre doing then IMO its wasteful. 

 

So get over it dude.  Spend your cash on what you want.  Just know at 3000 miles your throwing away good oil.  At least take it to be recycled.  That's all I ask

No pep talk jake... Just shining some lite on the ignorant a$$way you talk to people. Dont matter what amsoil or any other company says. Why would you talk trash to someone who wants to be more attentive to their personal belongings and make them last 10x longer then they would if they followed said oil reps rec?

Screw it man. It aint worth it.
Theres always that guy.... Later

I was involved in testing extended oil changes, diesel and gas in the 90s and early 2000s. The diesels were in land clearing equipment that ran all day at around 2000 RPMs. The goal was double the oil change intervals from 200 hours to 400. This was in high dusty conditions with air cleaner filters cleaned or changed daily. This involved hundreds of equipment. The oil (Amsoil) performed as advertised. The goal was less down time for oil changes and disposal. The gas engines were 1 year or 25K miles, filters every 12K. Same oil same results. I wouldn’t feel comfortable doing this with today’s engines and generally would follow the severe service schedule in the manual. My Toyota Camry oil change interval is 10K miles. I plan on keeping it 200K miles ( would be the first time ever) so I half that.

To my point, why is there so much deviation on the OEM recommended interval on oil changes but not everything else? Why do some follow all the OEM specs on other things but not oil. Amsoil isn't "Dexos 1 gen. 2 Certified" for whatever that is worth; but it IS worth something to some people; take that into consideration. It seems that these friendly discussions on a few choice topics always draw the strongest reactions from folks. Personally, I am perfectly content operating my equipment using OEM recommended/"approved" parts/lubricants following an OEM schedule of maintenance. No one can fault me for it just like I can't fault others for changing every 3k. I am always just curious as to why people still feeling so strongly that it's 3k or bust; it's not 1968 anymore. Hell, even Jiffy Lube doesn't recommend 3k anymore. Seems to me, the "cheap insurance" argument would be a $25 Blackstone test on varying intervals until a "perfect" balance is reached between miles driven/hours of operation/manner driven vs. remaining oil life. That would be a more true representation of what is "best."

Good commentary. Here's the thing. Every enginge isn't the same. Theres different tolerances, oil consumption, oil contamination, blow by,etc. If al things were created perfectly equal sure id follow what ever joe blow says. Unfortunately the man up in the machine shop didnt create them all equally, so how can eveyone use the same or even recommended extended change intervals? Now oil testing would really be the way to see how long one could go on their vehicle, and even still that interval would change over time as the engine wore. It really depends on a case by case matter. But I'd really hate to be that guy who recomended someone wait 25k and found out 10k in he lost his engine.

3 K mile oil and filter changes for me because that's what I like. 

SIMPLE

I do my own with off the shelf oil and now an upgraded oil filter.

Yes, 25k would be extreme...I am a middle-of-the-road kinda guy...5k or even 7500 seems reasonable to me based on everything from the oil manufacturers, GM, and the OLM in the DIC. I like these topics because I value everyone's opinion and experience. I got 3 free oil changes with my truck and I just used the last one last month. I only have 17,500 on my truck; the first two were at 5k and the last was done based on the OLM. Now that I am planning on taking the helm, I am going to send it out to Blackstone when the OLM says "Change Oil Soon" or whatever. If it looks good (and I assume it will), I plan on sticking to following it and testing every other change. I drove an '07 F-150 for that past 10 years until I bought my Sierra. I always just used Motorcraft syn-blend and a Motorcraft filter every year (I drove a company car then and only put like 8k mi./yr on it)....I never did a test but never had a single problem.

What filter are you using?

[diyer2]

Wix 57045.

A little over an inch longer/taller than stock.

After looking at my choices this is what I settled on.

I wanted more filter area but cost effective being I do 3 K mile  changes.

I don't know if this filter will work on newer trucks.

I think newer requires different oil pressures.

The 57045 filter has a 12-15 psi bypass spring. The WL10255 is the exact same filter with a 22 psi bypass spring. This second WIX part number is the 'updated' version for the Ecotec3 applications of all displacements and cylinder counts.

Does the second part# have an anti backflow valve?

Usually by mileage. Around 5000 to 6000.
