Default Anybody notice the differance?

I switched my truck over to AMS Oil last month and they claim the fuel economy is suppose to go up. But right now it looks as thoe my fuel milage has not gone up. And the engine sounds a little differant. Is there another brand out there you guys recommend like Royal Purple, or Mobil 1 that actually give better fuel mileage?

No motor oil is going to increase your gas milage...Its advertising and their "lab tests" are under crazy, unrealistic conditions.

A lighter oil has less vescocity and may reduce drag in your motor, but will not change your milage (by a noticeable, measurable amount.) Your cumbustion chamber is a fixed size, it needs that optimal 14.7:1 air/fuel ratio to run properly. So as long as your combustion chamber is the same size, it is going to need the same amount or gas to run correctly. A few other factors are gearing, tire size and tire pressure. The less resistance the better, but your engine was designed with a certain wieght oil in mind. Anytime you heavily accelerate or are under load, your fuel system is running richer than 14.7:1, hence why you see your gas gauge go down.

Your driving habbits can improve milage!

I like using the synthetics, good for cleaning the engine among other things but the only difference I notice is that it has cleaned out some sludge from my engine

If it's around 15-18, thats normal for a 4X4 Ranger.

Oil's function is to lubricate the engine, keep the temps down and prevent wear. As stated above the lighter (thinner) the oil the less load or drag. You may notice a mileage increase if you: go an entire year on conventional oil tracking your mileage after each fill up. Then the next year change to a synthetic oil and do the same thing.

The mileage increase is so slight it would take that long to see the difference. Synthetic beats conventional hands down for protection.

The best way to increase gas mileage is to control that thing in your shoe at the bottom of your right leg!

I gained mpg's by switching to Royal Purple.
Put it in the rear end, the transfer case, the tranny and the engine.
It does work.
I didn't do it to gain mpg's, I did it because I tow.

How does one get poorer gas mileage on the highway, then in the city?
do you mean 11 city, 15 highway? That is terrible mileage for a 2009.

Nuthin'

I did it myself. Dropped the pan and put in a B&M drain plug and a B&M remote filter kit.
I know it didn't all come out. I have drained 4 to 5 quarts at a time, 3 times now.
