M1 0w-30
Does anyone run M1 0W-30 in their DiscoII? I have 121k on mine overall but 58k on the motor....The M1 bottle suggests that it is ok where 5w-30 and 10W-30 is suggested to be used but you are suppose to get better gas milage.
Thoughts???
Thanks,
Steve

If you go by the book 30 weight oil is OK, but I would suggest at least 5 or 10W. If you like Mobil 1 (as do I) and you want a 0 weight, they have the 0w-40 European Car Formula which is what I use in my Audi. I use the M1 High Mileage 10W-40 here in my Disco.
Also, even if you put in 20 weight oil you will not see an increase in fuel economy in this engine. It will remain unchanged regardless.

There is no such thing as a "0" weight motor oil, "5" is the actual lowest they can go.
All the "0" means is that it will flow through the engine at a lower temp than a "5" weight oil.

def no on the 0-30w.
best way to gain some gas miliage is to be light on the pedal, lighten the truck as much as you feel practically possible, check them tires often for pressure and alignment, coast when possible (downhill, before peak of hills etc and carry speed in safe manner on turns to not brake then gas on to resume), run the aircon withouth the compressor runnin as much as possible, and keep up with your intake filter for build up of dirt (or go with a more open system) and keep the tune ups regular (dont forget use good gas!)
sad thing is these trucks are very heavy, about as aerodynamic as the international space station, have constant 4x4, low range gearing, and a motor that doesnt have the torque to accelerate it smoothly without decent input. but, only sad because none of that is good for economy, but VERY good for everything else about it

I agree with all of this and I'm going to throw in my $.02.
I use Rotella 5w-40 in the winter and I average 15mpg as a daily driver.
In the summer I use Rotella HD-30 and I average 15mpg as a daily driver.
I have also used Rotella 15w-40 in the summer and have averaged 15mpg as a daily driver.
In other words...motor oil ain't gonna make no difference buddy.
Now if you were in a lab with a computer controlled engine on a dyno where you could take micro measurements of fuel economy, yes, a lighter oil would make a difference.
And now read the fine print, here it is right on Mobil's web site, the estimated savings in dollar amounts if you use their Advanced Formula 0w-30 motor oil.
Mobil 1 0W-30 Advanced Fuel Economy
Wow, a whopping $147 over the next 50,000 miles.
Totally not worth it especially when that oil change will cost you twice as much as a heavy duty oil change with something like Rotella.
