There have been independent studies on 100% filters and they have found that the oil never needs changing. Only topped off and cleaning/changing of the filter. With 100% of the oil going through the filter all of the contaminates are removed leaving the oil clean and like new. Some of these studies were done on New York taxi cabs and none failed.

I think that the base of a motor oil is viable for much longer than the average oil change interval. However as others point out, this isn't the issue. Viscosity remains acceptable long after it's expiration, it is the additives that break down and wear away over time. Things such as rust and foam inhibitors don't have a limitless lifespan.

That said......

I owned a Toyota Pickup with an R-22 4 Cylinder engine and a cabeuretor. It was 4x4 regular cab, regular bed. The truck averaged about 25k miles per year for the first 10 years of it's life. The average oil change interval was 30k miles.

It wan't even a 12 month ritual to change the oil. It was checked frequently and it hardly ever needed to be topped off. In fact over the course of the intervals little more than an ounce or two were added for good measure.

This was a company truck and then later my personal rig.

While I am meticulous about frequent oil changes, the truck still remains in the family today after 8 years and it runs like a top. No major issues ever related to the engine or drivetrain.

I wouldn't try that with a Ranger or Colorado pickup.

Isn't that the same Toyota truck that you see in every movie of some war torn country where there are 4 guys riding in the bed carrying machine guns and the truck looks like its been to hell and back? One such movie is Blackhawk Down. Those trucks are indestructable.

well, if you think about it...let see: Mobile 1 Oil Filter roughly cost $12.00 ea. now if we all do oil change for every 7000miles..after 10 changes, it will pay for it self once you hit roughly 70,000 miles give or take. Consdering..that's pretty cheap!!

I could see your point if you put a lot of miles on a vehicle per year..But I don't . If you only put 12,000-15,000 miles per year, that would be 2-3 oil & filter changes per year. Ten oil changes would take 4-5 years...I doubt it would be worth the initial cost since most people don't keep a vehicle much longer than that..If that long.

If you use the Supertech oil filter, cost $2.06. You could buy about 50 of them. If normal oil change is at 7,000 miles, you would have to reach 350,000 miles to break even.

I am not in any way slamming the product..It's just not for me.
