You Know What Really Pisses Me Off...?

It's rated at 600 hp and 2,050 lb ft torque at 1,200 rpm with a governed speed of 2,100 rpm. The new engine promises up to .5 mpg increase in fuel economy, according to preliminary tests of prototype engines.

But here's the kicker: Cummins' expects its latest powerplant will run 1,000,000 miles to overhaul without unscheduled downtime. The engine contains 1/3 fewer parts and weighs 300 lb less compared to a comparably equipped N14 engine. And the Signature 600 features an advanced filtration and monitoring system that doubles oil change intervals to 50,000 miles.

Now why do the Big Oil companies keep preaching changing your oil every 3 months or 3,000 miles. All this time I'll bet you thought all this high technology that is changing the rest of the world was passing by motor oil.

Could it be that technology really hasn't passed up motor oil, but that even the major automobile companies are to a great extent at the mercy of Big Oil.

But lets think about it. When you go out and purchase a new Peterbilt road tractor, or Kenworth dump truck, do you get a Peterbilt or Kenworth engine - NO. You get to choose whether you want a Cat, Cummins, Detroit Diesel, etc. When you buy a Chevy, what kind of engine do you get. You're kind of stuck with a Chevy engine, aren't you?

Now, lets imagine that you are purchasing 500 new road tractors for J.B. Hunt, and you can choose exactly which engine goes into these tractors. Can you picture the competition between engine manufacturers for that order? And what might you as the Purchasing Agent be looking for in deciding what manufacturer to supply your engines?

This is why truck manufacturers are way ahead of the automotive manufacturers. Even the diesel engines for pickups by the big three call for oil changes in the 5,000 mile range. WHAT'S WRONG WITH THIS PICTURE?

The fact is: technology has not passed up engine motor oil. AMSOIL has sold engine oil with a guaranteed change interval of one year/25,000 miles since 1972. We have been in the forefront of providing full flow oil filters that provide for extended life to 12,500 miles or 6 months, which ever comes first, and washable/reusable foam air filters.

SO WHY DO YOU STILL CHANGE YOUR OIL EVERY 3,000 MILES/3 MONTHS???

And AMSOIL has shown in field demonstrations that they can take a road tractor and, with a change to AMSOIL in the engine, transmission and differential, fuel mileage can be increased an astonishing 8.2%. Just using AMSOIL's Severe 75W-90 Gear Lube has been shown to increase fuel mileage by 4.83%.

And when coupled with Used Oil Analysis, Hayward Gray, with his 1990 Mack Truck, went 630,000 miles total, the last 409,000 miles without and oil change. When the engine was torn down by the local Mack dealership in December, 1996 and its parts were examined by an engine rater from Lubrizoil, a major oil additive manufacturer.

The findings? The engine showed light to moderate wear throughout, and, according to the engine rater, the parts he examined -- cylinder liners, pistons, rings, bearings, valve train components -- could have been put right back in the engine and would have continued to provide the good, dependable service they had provided all along -- after 409,000 miles without and oil change!

And these results are not unusual. They have been demonstrated time and time again in other similar field demonstrations.

Change your thinking, not your oil.
