does anyone know when i should change the oil for the first time on my ram and when can i start using full synthetic (royal purple)

 

Many new cars are shipped with synthetic oil in them from the factory. Synthetics are no "slicker" than mineral based stock so break in is not an issue. Synthetics do have a benefit in that they do not have paraffins and other impurities that were not able to be refined out of the mineral base stock. The hydrocarbon chains of synthetics also do not break down as easily and do not contain viscosity enhancer molecules that break down lowering your viscocity rating over time and use. That being said, I recommend that you change your oil at 2,500 and 5000 miles, then every 5,000 miles afterward. You can use any quality name brand oil you wish. I think the best for the buck is Motorcraft Synthetic Blend 5W20.

 

RP is great stuff, but may be too much for us, IMO.

I am going to get a 6000 mile sample of Castrol synthetic tested soon, but I am sure it is going to be fine.

 

Oil selection for a pickup especially with the Hemi is not a big deal. You have to remember, most of the time, these engines are below 2,000 rpm and have a seven quart sump. It is not a stress environment at all for the oil as far as internal combustion engines go.

 

Exactly. I completely disagree when people argue we need to change our oil at 3000 miles, unless of course, that person tows a heavy trailer everyday.

 

Or drives a lot of dirt roads or in dusty environments...

 

Best advice I can offer is let the dealer do the first one.. Click on the link below.

I am going to have mine changed by someone else the first time and have them install my Fumoto valve at the same time. I have used one on my Duramax for 7 years and it makes oil changes a breeze.

 

i got my first change done a few months back and about 2500 kms into the new oil the oil change light came on again. anybody else get this. it says its supposed to be every 10,000 kms now. i ignored it. i got synthetics in it so i should least hit 5000 kms

 

My light first came on at 2500 miles. I changed the oil and it came on again at 5000 miles. I reset it and am going to wait until there is 6000 miles on this oil. It is synthetic.
