Hey Guys,

I have a 2000 Durango 4.7 4X4 with about 112,000 miles.
I was wondering what you guys' take is on the right viscosity to use for the 4.7. I looked in the owner's manual and it says that while the 10W-30 is preferred for the 318/360, the 5W-30 is preferred for the 287. In the owner's manual it also gives a chart showing the different temperatures that it will be driven in. I live in Portland, Oregon where it rarely gets above 100F and rarely gets below 32F. We used 10W-30 for a long time and I recently switched to 5W-30. I was just wondering what you guys thought about this issue. All comments welcome.

Here is a good thread that explains about oil -> https://dodgeforum.com/forum/1st-gen...nions-mmo.html

Personally i stay with 10w-30 in my truck. 5w-30 is not really needed unless you live in a cold climate with negative numbers IMHO

 

for the 4.7 i would suggest running the 5w30 if its available in your area since that is the preferred viscosity for the 4.7. whichever you pick should work fine just pick one and stick with it, dont be constantly switching back and forth (changing over like you did is fine, just dont swap viscosities every oil change or ever year)

 

My D leaks and burns a little bit of oil, I tried 5w30 in the winter onetime and I think it used more oil than with 10w30 so I stick with 10w year round.

haha my dad never changes the oil in his truck, it changes itself while you drive it because it burns at least a quart every 500-1k miles! He has used about every different type of oil in that ranger from 5w to 20w all mixed together and 13k miles and counting on an oil filter. I dont think he will ever change it.

 

Just follow what your manual tells you PERIOD. Unless your driving in extreme weather conditions or having leaks, burning oil etc... Stick with what the manual says, they tell you a recommend viscosity for a reason. Also use a synthetic if possible, but not really necessary.

 

Yeah I am having no problems, other than a fluctuating oil pressure gauge, but it never turns the CEL on. Since it says that 5W-30 is "preferred" for the 287, I think I will just stick with Conventional 5W-30. I don't wanna pay more for High Mileage oil. I used full synthetic for a while but I just don't think it is worth it. I realize it costs twice as much but you can theoretically go twice as long without changing it. Full Synthetic for a 12 Year old Durango seems a little overkill. Some on here might think that last statement is blasphemy lol. I think conventional 5W-30 will work fine.

 

iv run conventional in mine for its entire life, as long as you change it on a good schedule you should be just fine with either.

 

Just use a good brand conventional and you'll be fine. Mobil, Valvoline, etc. I use Mobil Super High Mileage in mine. You can buy it at Walmart cheap. 201k miles and runs great
