Why you should change your oil

[94BULLITT]

Most people probably don't even watch a oil pressure gauge.

Could be, I know Dodge's use a switch to show pressure to the ECM. The ECM then uses coolant temp and rpm inputs to determine what the dummy gauge shows, not a real reading at all. I have installed Isspro gauges in my truck, including a real oil pressure gauge.

interesting.. some sort of 'data' hash, showing you a snapshot of engine condition.. but giving you no real hard data.

In my 450 i have some gauges ( aftermarket of course ), on the drivers cab windshield post..real gauges..

That's because Ford doesn't use an oil pressure gauge. It's an on/off switch that just grounds with any pressure over about 8psi. This makes the gauge go to the midpoint.

As far as I know GM is the only domestic or otherwise that still uses a proper functioning gauge.

I did verify our GM trucks have "real" gauges on most of the cluster. Ford has more idiot gauges. Our GM truck tans temp gauge travels up slowly, like it should. The Ford gauge reads "normal" before I drive out the driveway in winter.... lol.

Beware of Ford trans temp gauges. They are really useless unless you watch it all the time. I'd rather have the "EWS" like in our bigger CDL rigs. A real proportional gauge and a buzzer & light if the trans temp, engine oil pressure or air brake pressure reach high/low levels. Here's a good example of a Ford trans temp idiot gauge. Mine wont really warn you until it's too late:

The only problem is the gauges don't work all the time in a GM truck. Gm uses the same gauge setup in some vehicles like Ford and many other manufactures.

My 2000 Tundra 4.7L has oil and temp gauges not a switch. The old ford 71 4WD F250 with 360 engine on the farm had a guage but always ran on the low side. Another Ford story, i worked for Agway as a farm service tech and when I started got the "old truck" a 72 1 ton dually with a service body, 360 engine and 160K mi. Just said "check the oil every day" well it used a quart every two days, and we ran that truck to 200K and never let me down anywhere - just oil and gas and go.

My first own truck was a used 89 GMC 1/2 ton 2WD 6 cyl and 5 speed with 90K mi - would get 22 hwy MPG - only problem was the brake lines rusted at 110K mi in 1998.

So have had good experience with all makes and models, I think good maintenance = good experience with most things.

My first truck was a 1970 Ford Ranger Deluxe with a 360 cu C6 trans, oil bath air cleaner, and a spin on gas filter. That thing was a tank.

I believe this to be true!

Never thought I'd see that!
