Don’t forget them osolators that fit on the resuscitators. You know them thingys that keep the backup gears from getting hung up in the reverse cogs? ???

Only problem is that every "thingey" displaces actual oil for less actual lubricatiing capacity. Years ago the engine manufacturers recommended straight weight oil for this reason. Polimers reduce lube capacity. Don't know about synthetics, they may have corrected this problem. I guess the engines of today are built for these oils in contrast with the earlier engines.

Hauling- It's true that the VII polymeres don't have any lubricity themselves. But they make the oil stay in places it would otherwise leave. Any manufacturer has to balance the runtime of an engine with the cold starts. On a cold start you need thin oil to get it to the places fast. When the engine is warm the single grade oil would be better. Modern engines are sometimes even designed to use these qualities of the oil. EG timing chain tensioner on BMW 4bangers. If you think you do your engien something good by using 5W40 instead of 10W40 the chain can start to oscillate and even tear off. Personally I do use the oil the mfg recommends. (They used up a bunch of engines to find out )<br>AlpineRAM

Alpine I run Delo 400 15/40 in the Dodge. In the old Detroits I ran Delo 400 40 weight.

These engines are so good, why do we even NEED oil???

I'm a brand new diesel owner and brand new to this site. Just bought a 1995 Ram Laramie SLT 4x4, automatic, and just love it. I pull a 32' 5th wheel (old timer 1979 Kountry Aire) and love to camp. My wife and I plan on going around the country as soon as we retire (4 years). About the oil thing, a friend of mine says to use the Shell Diesel Oil and nothing else. Whats the general opinion.<br><br>Thanks<br>Bill

Welcome to the site. You will love your new/old truck. As far as oil goes there are alot of answers. Lots of people use Rotella T and have no problems even with 500k+ miles on engine. I use Valvoline Premium Blue(I think that's what it is). It is the full synthetic and can be purchased at most auto parts stores or truck stops. Funny thing is you can actually purchase it cheaper than regular oil. Doesn't make sense to me but I am not complaining.

I myself use Amsoil in everything, time will tell if it's been worth it.<br><br>Later, Rob
