I just went to Amsoil a month or so ago, Mobil 1 before that. Amsoil is a bit more expensive, but from everything I've read, it is supposed to be a better oil. I think almost important, if not more so, is what filter you use. I don't think there is much use in going to Amsoil and then using the bottom end Fram (for example) filter. Again, the Amsoil filter is qite a bit more, but in this cas, I think you get what you pay for....

R...

 

Good point Chopper. I heard that K&N also has a good oil filter... I also have seen a Amsoil and it is almost twice as long... If you run synthetic you must have a quality filter!

 

If you run any oil you need to have a quality filter if you want your engine to last!!!

Capacity, Effeciency, By-pass operation, Filter Quality.

Imagine having a cheap filter that becomes clogged or goes into by-pass mode for some reason or another. Guess what all of the dirty oil is getting circulated around your engine. BAD news for Bearing life.

Hence the reason I am so much for the best filtration that you can find. By-pass filtration meets that criteria, along with the best full flow filter I can find.

Also one thing about capacity. I now have a full flow filter on my F150 that is over twice the size of that cheezy one that is OEM. What does that hold? less than 1/2 quart?
the filter I have now holds over 1.5 quarts. Combined with my By-pass filter I am now over 9 qts capacity on my oil system

I'm sure the rest of the truck will fall apart before the engine goes!!!

 

How are you going to tell if it's better?

 

I am interested in running a larger filter myself.........what can we use?

 

You can't use anything short of the oem unless you go to a remote oil system either a dual remote by-pass or a single remote filter system like on race vehiles.

It seems there is only one filter with the thread size of our trucks(Its metric) There are other filters out there that you can get in different lengths, but not ours.

Summitracing.com has some relocation kits, Amsoil also sell both a relocation kit as well as a dual by-pass filter kit.

Fast and easy oil changes are now possible thanks to our Universal Oil Filter Relocation Kit! These kits contain all the parts needed to move the oil filter to a more convenient location in the engine compartment. The kit contains an adapter to convert the stock filter landing on the engine block to an oil passage, your choice of a single or dual remote filter mount, eight feet of oil hose for custom fit lines, illustrated multilingual instructions and all necessary mounting hardware.

Universal Oil Filter Relocation Kits fit engines with the following spin-on oil filter thread sizes: 3/4"-16, 13/16"-16, 1"-12, M18x1.5, M20x1.5 and M22x1.5. Designed to use oil filters with 3/4"-16 threads, such as Perma-Cool® P/N 81008 or Fram® PH 8A or equivalent (oil filters not included).

 

Thanks for the info gents

What about buying one of those filter relocater kits from ford? They were ?an option on some 4.6/5.4?

 

If you are already using RL you are using the best. RL is a group 5 lub. If you want the best you have to pay for it (you get what you pay for). Amsoil is a fine oil also but it uses a less superior basestock than RL.

 

Well I again disagree.

If redline is better.........why does it leave a bigger wear scar in the 4 ball wear test?

Superior oil=less scarring, and NO ONE, let me repeat NO ONE beats Amsoil in any test I have ever seen!

 

Then why is it so hard to get anyone to post anything that shows Amsoil is sooo much better than everyone else that is performed by an independent tester? I've seen a few links posted to Amsoil's website that were performed either for or by Amsoil where they all claim to be the best, but not much else.

We've beat the whole synthetic vs. dino or Mobil1 vs. Amsoil debate over and over. It would seem to me if Amsoil was measureably better than Mobil1, Redline and everyone else someone would have posted legitimate facts backing there point and ended the great debate long ago...

 

67mike. Read this post. http://www.corral.net/forums/showthr...ght=synthetic.

Like I said Amsoil is a good oil. Better than most and probably more than sufficient for most needs but still not as good as RedLine. Have a good day.

 

As some may have seen, I have posted a new thread asking is Synthetics (Polyol esters) can have a negative effect on lifters. I'm at 10, 000 mi. on my truck and around 5,000 I switched to synthetic. Now, I have a failed lifter or somthing of that nature, the cause soon to be discovered. There is a " Clacking" sound when at idle comming from the underside of the engine, loudest behind the front right wheel ( only things that far down in the block: lifters, pistons, rods, and rockers. Anyway, how would you recommend seasoning my replacment engine? Switch straight to synthetics ASAP or wait until the first oil change?

need help to make a decision...

Thank you!

 

If you use the ford OEM Reloc. Kit you are stuck with the same sized wimpy filter.

As you notice those aftermarket kits use a Ford FL1 (PH8a fram) which is the filter that went on most 351's and bigger. I would prefer this filter over any other, excpet maybe a large heavy duty diesel sized filter!!

Man I love large filters

 

Why do people disallow the testing results posted on the AMSOIL website?

First, if the results were not true or tainted, every one of the major oil companies would have their lawyers knocking on AMSOIL's door with a lawsuit. Agree?

Second, each of the ASTM and/or SAE tests must show repeated results of less than 3%. If the product tested cannot achieve this type of consistent behavior, they are disallowed. These tests are the industry's standard for product testing and are used by all lubricant manufacturers.

Third, AMSOIL puts the test results on their website and product labels for all the world to see. No one else in the industry has the cajones to do this. Again, if the results were tainted, the lawsuits would be stacked up.
