Best Motor Oil?

Question

What is the best motor oil to run in a 2004 Dodge?

Answer 1

Amsoil synthetic. See several motor oils (including Amsoil and Mobil-1) compared with ASTM tests: http://www.amsoil.com/redirect.cgi?zo=1463115&page=products/atm_testing/index_flash
You didn't say what year/make/model, but check out this website and go to the Online Product Guide and you can look it up: http://www.number1synthetic.com

Answer 2

Check for your correct type (10w-30 etc..) usually located in your owners manual. I've read about the studies mentioned above and others stating that there is really negligible difference between motor oil brands. Most of it's marketing hype I believe. Synthetics I believe are only slightly better in that they don't break down(at high temps) as traditional motor oils do. They still have to be changed at almost the same frequency and at a higher cost. I generally use a store brand motor oil as long as it meets the SAE standards and has the "API Service Symbol" somewhere on packaging. I'd stay away from recycled or similar used motor oils for obvious reasons.

Answer 3

personally I like Mobile 1 synthetic. synthetic is better for your engine, but as a previous poster said, for the regular oils there is really no big difference. Just differentiate between gas and diesel. different oils are better at absorbing fuel and the additives fuel companies put in them. as an example redline race oil and schaeffer's is better at absorbing methanol (schaeffer's has a diesel oil as well), and royal purple and a few others absorb alcohol more efficeintly. but im talking about race engines here just to make it easie rto understand the differences.

if you have 80k miles on your car or less synthetic is good but not required. otherwise any other motor oil will do. that is if your the average driver. if you drive a couple thousand miles a month or more look into synthetics and other oils designed to withstand the prolonged run time.

Answer 4

There was an article in Consumer Reports several years ago about what oil is best. They ran hundreds of tests with different oils in different engines. They ran the engines for 3-6 thousand miles.
In the end, not only did they discover that there was NO marked difference in oil brand names, but also that there was NO marked difference in using the same oil for 6 thousand miles as opposed to the industry standard 3 thousand miles.
They found that the ONLY time you need to change your oil at 3 thousand is if you work and live in an extremely dusty environment like a farm or something.
The bottom line is that you can use any oil you want, and use it for up to 6 thousand miles.

Answer 5

Ok what kind of Dodge?? I would recommend Valvoline or Pennzoil are the best in my opinion. Also for 4 or 6 cyclinders recommend 10W30 or 5W30 and 8 cyclinder 10W40 and I think that 20W50 is to thick to use in anything. Again this is just from my experience >>mechanic for 15 yrs. on my vehicle and most of my families

Answer 6

Mobil (not Mobile) 1. It lubricates better, lasts a lot longer and handles extreme heat and cold better than conventional oil.

Answer 7

5w30 synthetic ... probably mobile1 (if its a gas motor)
if its a diesel, 5w40 diesel spec mobile1
