Oil Filters prevent the "crap" from floating around the motor. Get a good quality filter that is designed to last and you will be in good shape!

 

People complain that the price of gas keeps going up but they have no problem wasting money on engine oil. Ford recommends 5000 miles per oil change of course this varies on conditions. The oil we have today blows away all the crap they had years ago. The engines we have today blow away all the engines we had years ago. Get with the world of today and stop wasting good oil. Someone posted that Ford recommneds 5000 so you will wear out your engine so you buy a new truck, duh.... here's your sign.....
You don't think the oil companies keep the dumb idea of changing oil every 3000 miles alive?
Thanks, this way the oil companies get richer, the old oil is burnt and then pollutes the air so more people complain about pollution and we end up with tighter emmisions.

Also do some homework, a judge ruled that synthetic does not mean full synthetic. All but about 3 synthetic oils are derived from dino oil now cause it's cheaper to make. I wondered why Mobil 1 was $20 gallon at Wal-Mart......

Think about this, how different is the grease we use today than the grease we used 20 years ago? How many grease points are on new vehicles? About 3? Don't you think if grease can go so much longer oil can?

Instead of guessing what condition your oil is in when you drain it, have it tested. You can get your oil samples tested at most NAPA stores. Once you have done this for about 10 oil changes you will see the money and oil you have been wasting all these years.

 

4-5k with Mobile 1.

 

5000 with Mobil 1 5w-30

 

every February 29th...

 

20k if pushing it. I don't know any oil filter that could hold all the crap.

I am not trying to start something but we in the quad community have had problems with Amsoil. It almost seems it is too good.

I guess I would rather change my oil every 3-5k and know my engine is going to last. Then run some kinda super duper oil in my system that they say last 10, 15, 30k miles.

 

A case of valvoline cost as much as 1 oil change of Ams Oil. Atleast that is what it was last time I checked. So it dosen't matter which way you go the oil companies are getting richer.

Grease???? What does grease have to do with anything????

Who wonders if there oil is bad or not? Get it tested? Guess I never took it that far :/

 

every 10-15k here, mobil 1 filter and oil

 

damn that is every 4 years!


i use castrol and do it every 3-4k

 

Careful careful - No bashing needed....

First off - It is not a Avon like basement bussiness. You need to do a little research before you bash.

2nd. Don't know about you. but it takes me more then 12 minutes (.2 hrs as you word it) to change oil. By the time I pull the car into the garage, Get the jack out, lift the car up, put jack stands under it, lower the vehicle down to the jack stands. open the oil pan plug, take the oil filter off, oil the new filter, replace the filter, finish waiting for the oil to drain, replace the plug, lift the vehicle back up, remove the jack stands, lower the vehicle back down, Now fill the truck back up with oil and check the other fluids... yea a little more then 12 minutes.

BTW - A 2001 Ford Ranger 4x4 4.0 calls for .5 for the oil alone and .8 hrs for the Oil and filter... NOT the .2 that you so boldly stated above. So you better check your numbers a little closer before you start dropping numbers out there. I do alot of shop work and have full access to manufacture repair manuals and book time's....

Performance gains are not noticed? That is very broad statement... There is a TON of performance differences. One that is VERY Noticable at this time of year is Pour Point (PP) <the point it remains a liquid. With a PP of -58 this is very important in the COLD winter starts... Lower the PP faster the oil will lube your moving parts. This alone will make your starting easier on alot of parts of your truck. Your motorcraft Syn. Oil has a -33 PP < So your oil isn't even considers a liquid any longer at this temp.

Here is a link you may want to check out for performance differences. ALL TESTS DONE BY A 3rd party...

You can see AMSOIL leads alot of the areas... Not all though... But you can see how they compare.

Well this isn't a AMSOIL thread so I really don't want to make it one.. The question is "How often to change oil in a 4.0". As you can see this is a very wide open subject. It all really depends on your personal thoughts of Syn. vs. Dino oils. Change as often as you like, Whatever you do with be right in some peoples eyes and wrong in others. I personaly don't care, I was a 3k mile guy for a while. I came across AMSOIL, was sick of changing my oil every 3-4 weeks, so I changed to AMSOIL for the added change interval. Now, after using it in my car I swear by it, I have personaly seen many advanages, and have trust in technoligy. I have pulled motors apart down to the bare block and have seen first time the original hone (sp) marks on a motor with more then 100,000 miles on it that ran AMSOIL from the 1st mile... Do as you like... I use AMSOIL

 

I'm with Wholesale here. Been using AMSOIL Synthetic in my Ranger, Oil and Transmission since 35k (@ 100k now) and I've never had a problem. Typically go between 6-7k per oil change and usually just get a new filter every time as well. It's great stuff and anyone I know who uses it, loves it if for nothing else just the added mileage between changes.

 

I use Mobil 1 synthetic 5W-30 and a Wix filter. I change mine about every 5000 miles or so which is only once every 6-7 months for me. I check it once a week to keep tabs on the level and make sure there is nothing else in there like moisture. Been fine so far and I just topped 30,000 miles earlier this week. Oil quality and lubrication properties have improved so much nowadays that it is no longer necessary to change it as often. I always recycle the old oil and have a 5 gallon container that is enough to hold the old oil from the truck, the wifes car, the boat, and the lawn tractor before it needs emptied. A good tip is to save your empty new oil bottles and set them upside-down into another via a funnel for a day each. You'd be suprised how much oil is left in the bottles after you empty them and this provides you with a little extra for a top off and helps to save the enviorment.

 

WOW - the idea of turning them upside down is a super idea... Never heard of it, but I have always thought there was alot left inside the bottle when I tossed it. Going to start doing this myself now thanks!

 

I am getting away from the quick lube type services and doing my own now for peace of mind. I picked up two NAPA Gold Series (WIX) filters today and a 5 qt. jug of Castrol GTX.....Not sure if I want to go synthetic or not....I did until I talked to a buddy of mine that used Mobile 1 in his dirt track car one season and blew a motor mid season for no apparent reason. He says you couldn't give him a quart of that synthetic oil. He does his own motor building and everything, so I do value his opinion.

 

I change mine every 4 months since I never get 3000 miles on the oil and filter. I only put about 6000-7000 miles a year on the truck. I have used Mobil 1 Synthetic since it's first oil change when new.

 

I usally take my truck to get my oil changed no less or no more than 3,000 miles

 

That SUX

AMSOIL would have bought him a brand new motor! Their warrenty is really good. Little to late now.. The damage has been done. Also the blown motor had to be due to something, they don't just "Blow", if he couldn't find a problem, maybe someone else should have looked it over nad found the problem...

 

All he said was a rod came out of the motor....He said he usually know when he has done something that will cause a failure like that, like running it too hard or something, but this one should have been fine. Don't know. I'm going with regular petroleum based oils until I do more research.
That is cool Amsoil backs their product like that.....Ever hear any good/bad about Royal Purple?

 

I can get my hands on this stuff too... I have not heard really anything positive or neg. about them. Their client base I think is very small (relitivly speaking). AMSOIL and Mobil1 do majority of the Syn. bussiness. I know that doesn't help much, but it is my honest option.

 

Change it every 3k, use Castrol GTX or synthetic.

 

I change it Every other week and use it to Fertilize my garden! You should see The size of my Tomatoes!
