i know the oil is supposed to be changed out every 3000 miles. what kind of oil would u guys recommend?

how often should i change out all the other fluids?

 

I have a 9.5 qt oil pan and I change every 3k miles

trans I change about every 20-30K

Rear Diff about 30-40 k

Coolant change bout every 50k

Brake fluid 60-75k

but to start off, on a new used vehicle I change out every fluid, that way you know the exact condition of everything.

Change the plugs with TR6's gapped at .032-.034

I change the fuel filter every other oil change

Good luck!!

 

thanks haybale. what kind of oil do u use? ive heard mobil1 is the best? the previous owner to a mobil1 lube express. should i continue going there?

 

most any oil will work well if it is changed on a regular basis

currently I run Castrol GTX 5w30 dino oil, once I hit 15k on the built DMPLB then I'll run Castrol Synthetic Blend

 

Royal Purple is the only way to go. I just changed over all of my fluids, that I could, to Royal Purple. You will feel and hear the difference. It cost more, but is well worth the added expense. Once you start using it, you won't use anything else in your truck. The 5/20 for our trucks can be hard to find at times, at least up here in Alaska, but when I find it I buy it 2-3 cases at a time. I have Mobile1 0/40 in my SRT8 Jeep and it seems to work fine, but I am hoping that RP will make a 0/40 at some point in the future.

 

is royal purple the brand? and about how much did it cost u to switch out ALL of your fluids to RP?
