Dodge Ram Care and Maintenance

How many RAM owners out there have switched to synthetic engine oil? I just had a oil change at 3100 and I am considering going to synthetic, but I would like to hear some opinions from experienced owners.

    After 3k I changed to mobil1 10W30. It's only been one tank since and I have noticed marginal change in engine performance (02 QC SB 4.7L 4x4 5sp). I have in the last few tanks seen the mileage steadily increasing. I changed for the long term benefit. It has increased the oil pressure and decreased the engine temp from the dash gauges. I tend not to put too much stock in those kinds of measurements the accuracy is in question. So I'll look for long term differences. I did switch to a better filter ($12 Fram X2) and the oil at the warehouse club comes in a box of six for $22 (The exact amount that the owner's manual calls for). So for a grand total of $34 dollars I'm good for the next 5k miles. I'm sold. Good Luck
  • I have used Mobil1 synthetic oil in all my vehicles for years. I was sold in it when my 1987 Jeep wrangler (47K miles) broke a wrist pin and upon disassembly, the engine was so clean, it looked like chrome. The mechanic was impressed, and so was I. My ram has used Mobil1 since new, and it runs great. I highly recommend it.
  • I have been using syntheic for 5 years and never had a problem. You will see a perfomance increase and better gas milege. I have tried different oils and best one yet is Royal Purple. It's expencive but well worth it. It's designed for racing and keeps your engine temperature down by 20-50 degrees.
  • I have a 2001 Cummins powered 2500 Dodge Ram and have only one complaint - the incredibly easy to scratch exterior paint. Any suggestions about a wax or other product to help protect the cheap paint? My dealer says that the durability of the paint has dropped due to EPA restrictions on the volatile paint solvents in new vehicle paint. I question the accuracy of that answer because the paint on my otherwise wretched 2001 Outback wagon looked like new when I sold it recently. The Subaru Outback is built in Indiana and is subject to the same EPA restrictions.

    Other than the paint, my Dodge Ram is a real jewel and has become my everyday vehicle in spite of the fact that I bought it mainly as a business truck to move mobile labs in the oil field. Mileage is always over 20 MPG and recently has increased to 22 MPG. Absolutely incredible for a 3 1/2 ton truck!! If only DC could do something to improve the quality of the paint, they would have the perfect truck in my opinion.
  • My 1996 dodge ram 4x4 laramie full size in my opinion is costing me far too much in maintenance from: front end track bar to fifth gear trans. failure to heater/ac. module failure and other misc.repairs to the tune of $5000 in one calendar year
    I purchased this vehicle Sept/2001 mileage 60000 mi. currently 75000 mi.
    I am asking other owners for their input as to if this is normal and what I may expect inthe future?

    Does synthetic oil affect the warranty? Anyone get synthetic oil changes from a national chain, e.g. Walmart or PepBoys? How much is it? What kind of gas mileage improvement can I expect?
  • inukeu2inukeu2 Posts: 23
    Synthetic oil will not void your warranty. It meets and exceeds minimum standards specified by the manufacturer. Lube shops will use synthetic if you request it but you will pay quite a bit more $6/qt. Off the shelf it runs $4-5/qt. for Mobil 1 or Quaker State or Castrol. I think royal purple is a little more expensive but users swear by it. I've saved money by purchasing at a warehouse like Sams or Costco. A 6qt. case goes for $3.50/qt. and 6 qts is exactly what the manual calls for. I've had good luck with synthetics ever since I started using them. Don't expect noticable changes in mileage or horsepower but rather expect long term results that will require less repairs at less expense. Now that's not to say that I can't tell I'm using synthetics. It runs smoother and I haven't had any of the idling problems that others have posted about. Startups is probably where I notice the biggest difference. They are smoooooth.

    Is there any suspension/tire modifications that I can do to my 03 Ram 1500 to give it a softer ride?

    I do very little hauling, no towing, and use it as a car 99.9% of the time.
  • It depends on the type of wheels you have. If you bought your truck with 20" wheels you'll enjoy the great look of the truck but suffer a stiffer ride. The 20's have a low profile/short side wall. This means the sidewall cannot flex as much as regular tires and you get a stiffer ride. With 17's my truck rides like a Cadillac. If you have 17's and the ride seems abnormally rough take it back to the dealership and have them check it out.

    Mine has 17 inch wheels. It's a short bed regular cab, so I'm sure the short wheelbase contributes to the hard ride.

    Was just curious if they had "softer" shocks available.

    @980 miles I changed to Mobil 1 and a Mobil 1 oil filter.

    My trucks' owners manual calls for 6.0 qts., but it actually used closer to 6.5 qts. I guess the Mobil one filter held a little more.

    How often do other Mobil 1 users change their oil?
  • You might lower the airpressure a bit to try and take some of the harshness out. Shocks generally don't affect ride as much as they do bounce, or damping effect. I'm surprised the 1500 with 17 inch tires would ride that rough, but the short wheel base could certainly have an effect, especially in terms of porpoising on uneven highways.
  • Mralan, I have used mobil one in all my vehicles for the past 15 years or so, and change oil and filer on the average of every 5,000 miles. Used to do it myself till it became so difficult to dispose of used oil, so now I take all except the RV to Walmart stores where I am allowed to watch them change oil and lube the chassis. They perform this service for under 30 dollars. To do it myself costs me nearly 25 for a 6pk case of mobil 1, plus the cost of oil filter. Never had a problem in the past 3 years letting them perform this service...and I don't have to dispose of the oil/filter.
  • mralanmralan Posts: 174
    Yeah, my M1 oil change and M1 filter cost $61.00 with tax. I was looking to decrease that a little by going with a less expensive filter next time. What brand filter did Walmart use with your M1 oil change?

    My truck is running a little softer now. The dealer had over 45PSI air in my tires. Now I'm experimenting with 33 PSI from and 30 PSI rear.
  • My 2000 RAM 2500 V10 calls for Mopar ATF+3 transmission fluid. Does anyone know if ATF+4 is okay to use, my 2002 Neon uses this and is it just a newer version of the same fluid?

    What is the story with the 7/70 powertrain warranty on the 03 2500 heavy duty Rams . I heard there ia a deductible what is it ? and what does it cover ? Thanks
  • amoralesamorales Posts: 196
    I just purchased a '03 Ram 1500 HEMI-EXPRESS Laramie quad cab with the ground effects and 20 in tires. I got the 70,000 mi warranty and the deductible is $100. Covers powertrain. Need to re-check warranty info. Love the truck. Have 220 miles so far. Am debating which synthetic to use, Pennzoil/Pennzane or Mobil 1. I live in Calif near desert where temps reach 105 deg. May start off with 10w-30 for summer and then switch to 5w-30 in winter....

    Regards to all truck loving people

    Is what I read in the owners manual true ('03 SC 2wd short bed 3.7 V6 5spdM); factory fill and recommendation is 5W-30?!
  • dustykdustyk Posts: 2,931
    Yes. The factory service manual recommends 5W-30 as well.

  • pizza442pizza442 Posts: 110
    Wow, I remember when GM tried doing that on cars for a year or two around '90 and then went back. I think it had something to do with complaints in the east about cold starting and I know it was an attempt to squeeze a little more in the was of mileage for CAFE. Trouble is 5w30 turns to water out here in the West. Would I be ok going to 10w30 in my 3.7? It won't see a temp below 60* until next October! I see that it lists 10w30 in the comparison charts in the owners manual, but only mentions actually using 5w30. If I am stuck, I will use a synthetic blend at least; just can't stand the thought of 5w30 in 90*+ weather on a 300 mile trip to Las Vegas!
