dump some old black oil on it and watch it say it needs changed. i bet it is a light sensor deal. and probably has nothing to do with vicocity of your oil.

It tests the amount of acid in the oil. It's the same type of test we perform on refrigerants in the air-conditioning industry. We only "changed" the main engine oil in the USN fleet ships ever 7 years. We did have oil purifiers (one of my responsibilities as a Machinist Mate). And ran an oil test every 15 minutes while the ship was underway.

My auto tech teacher allways told us, 3months or 3000 miles, there is never a such thing as changeing the oil to much, it doesnt hurt a thing

Jeepers look at the neato digital tire gauge you get for only $19.95 + S&H.

That's the same guy that tries to sell his crappy tools and over exagerates.

Doesn't work based on a light sensor or viscosity. It works by measuring the capacitance and resistance of oil being tested. Fresh oil has a lower dielectric constant than dirty oil which is more acidic (higher dielectric) and might even have some metal particles in it depending on wear of the engine.

With the gas mileage I get the cost of oil is the least of my problems.

plus it sorta helps to have free Mobil 1 and wholesale FL1As at work. . . . . And still I run past due fairly often

[fordman]

i used to never change my oil. so i must have been doing it right then. all of the enignes i have ever lost have been low on oil or i just added some to fill it up.
