Your owners manual should give you the recommended weight.
Most newer vehicles in normal climates use 5w-30 oil.
The brand is not as important as the correct weight.

    Hi Stephen.. Thanks for your reply!! I didn't finish typing my question but you certainly answered it. I was more curious about the brand and if there was a difference in using one or another. I've been going to a mom n pop place who seem to take care of me very well but I always wonder about stuff and thought I'd ask..

    In some ways you get what you pay for, so some brands may have better quality than others. But they all have to meet car company standards to handle the factory warranty requirements.

    What's your take on synthetic oil? I keep finding information that suggests Royal Purple Synthetic is the best.. But the cost of synthetic oil is stunning to me! I know that making maintenance investment is better than replacing the whole engine or car.. but I am still cautious about switching completely...

    Well this is just my opinion based on 40+ years in the car biz. And I am in no way knocking your car. But I think the investment in synthetic oil is only worth it in engines desiged to last over 150,000 or 200,000 miles. In those cars the added cost would be offset by the savings in making those expensive engines last as long as possible. In economy cars, extra effort like high priced oil will not add anything over basic maintenance that you would see in the long run. As long as you change the oil and filter every 5,000 or so and do the required service work, you can expect to get 150,000 from the car. And that would be a good return on investment for the dollars.

    Ah ok.. No, I didn't think you were knocking my car. I know what I have and it's been a great car. I do the oil changes as suggested although my lube shop has me coming in every 3000 miles.. Thanks for all of your comments. It really does help!

How to change a cars oil.

Changing the oil yourself.

Changing the oil in a personal vehicle is fairly straight forward and easy. The first thing you need to do is to make the underneath of your vehicle accessible. You can do this a few different ways. You can use drive up ramps, a floor jack and jack stands or if you’re lucky enough to have access you can put your vehicle on a lift. No matter what your decision is you must take proper safety measures to keep your vehicle from moving while you are underneath. Always use jack stands and your emergency brake with tire wedges if you are not using a full lift.

Next you need to locate your oil drain plug, which is on the bottom of the oil pan. Remove it and drain the oil into some type of drain pan or bucket. After replacing the oil pan plug locate your oil filter and remove it. Replace the filter and lower your vehicle. Now, remove the oil cap that is at the top of the motor and fill the motor to the recommended level. Start the car after making sure there are not any leaks. After letting the vehicle run for a few moments, shut it off and check the oil level. If everything is OK, then you are done and have just saved your self a few bucks.
An oil change can make a dramatic impact on how your can runs and feels. The difference of a motor with fresh oil and one with old oil is huge. You could compare oil changes to dialysis; oil is your motors blood. When your oil is old and dirty your motor will feel sluggish, like a dialysis patient before their session and it will have to work harder for the results that would have been easy with clean oil. Motor oil affects almost every moving part in a motor. With clean oil everything will run smooth in unison affecting gas mileage and the life of the motor. Most manufactures recommend changing your oil every three thousand miles or if you don’t dive that much every three months, there are manufactures that recommend every five thousand miles but a higher grade and more expensive oil needs to be used.

What Is Recommended At 90000 Mile Tune Up For Chrysler Town and Country

At this interval it would be a good idea to check your drive belts, coolant hoses, motor mounts, suspension bushings, check for any motor oil leaks which could occur from any leaking gaskets. It is also a good idea to have change your spark plugs at this point as well. Normal spark plugs last around 50k miles before there electrodes start wearing out and losing their heat index value. They may still be functioning but at the cost of a lower grade spark and less than optimal fuel economy. If you've never replaced your power steering, brake, and transmission fluid and filter now would be a good time. I'd recommend replacing with synthetic grade fluids. I'd also recommend changing your motor oil on any vehicle every 2500-3k miles and adding a quality motor oil like castrol or valvoline, I personally use and recommend stp oil treatment, 1 bottle added at every oil change as well as marvel mystery oil in both my motor oil and added to my gas tank, this is remarkable stuff which keeps the internal components of your engine and fuel injection system clear of residual build ups. Be sure to also check and replace if necessary your air filter as well. good luck and hope it lasts another 90k miles for you

The best recommended oil for lincoln 1997 4.6 L V8 with over 300,000 miles also what would be the most fuel efficent recommended brand spark plug

originally it calls for 5w-30, but you could probably go to 10-30 or even 10w-40 since at 300,000 miles it seems logical that clearances are not what they used to be-and congratulations, that is some achievement!

How often do you change the motor oil? The motor oil filter? The automatic transmission oil and filter? What type of motor oil should be used?

Oil change recommended is every 3,000miles / 5000km for local short running around. If you clock up the miles quickly then extend the oil changes to 6,000miles /10,000km
Oil filter is every second oil change.
Use reputable multi grade oil 15W/40 or similar, Do not use standard SAE 30 single grade oil. You do not need to use synthetic / semi-synthetic oils either.

What weight oil should I be using???

now ford has came out with a memo recommending 5w20. Ford Motor Company reports that the company's switch from recommending 5W-30 viscosity motor oil to 5W-20 viscosity motor oil has saved 700 million gallons of gasoline since 2000. By reducing load and internal friction, lighter viscosity 5W-20 motor oils reportedly increase fuel economy by a half mile per gallon. In addition, Ford reports its use of 5W-20 oils has reduced carbon dioxide emissions by about one million metric tons a year.
Note: Ford issued a TSB (technical service bulletin TSB 02-1-9) regarding the 5w20 superseding 5w30 Owners Manual specifications. Applies to the majority of the car products back to the early 1990's.

So in short in your manual it may say 5w30 but now they recommend using 5w20.
if you need further assistance please let me know, Thanks, MIDwest-TEK

NEED OIL CHANGE

I would use 20/50 SE synthetic motor oil or high mileage or if you have the money, Amsoil is also great. Also change your filter every time and keep your oil changed about 3000 miles or so. It is overkill to change the synthetic and oil filter frequently, but will very good for your motor.
