I was using 5w-20 and then one of the techs at the dealership told me to go with 5w-30 because it runs better in our cars. 5W-20 is a little lighter and it will get to all the little nooks and crannys faster than 5W-30. So unless you like to turn the key and then floor it on a cold engine, I don't see any issue with running 5W-30 in your cars.
IF you like synthetic oil, then you're probably stuck running with 5W-30...I don't know of a synth oil that is 5w-20

It's a little harder to find, but all the major brands make a 5-20 full synth. I couldn't find Mobile1, althought i know they make it, but I found Castrol with no trouble. Of course if you are using AMSoil or Royal Purple, you already know how to hook up.
Todays oils are a lot tougher than they used to be. I don't have any problem using 5W20 as specified by Ford. I use Mobil 1 and don't have any trouble finding it. 5W20 flows better, therefore it lubricates quicker at start up where most wear occurs, and it also carrys heat away better.

Again, if you're using synthetic and changing your oil every 3-5,000 miles, and don't drive every day in the Arizona desert, I'm not sure what 5-30 is buying you. Sure, it's probably is fine, go and use it, but what's the point?
I wouldn't doubt it the story above it true. I don't think people realize how close Ford is to shutting down shop...with all the foregin car companies blowing them out of the water they would save a buck any way they can....I am going to research this topic.

Do you honestly think Ford would risk their reputation on just an oil viscosity ?? 5/20 is what's supossed to be used ! Everything else is just internet **** . ok bullcrap
Erm... Do reseach before posting. I asked this in a forum about oils only and they are all telling me to switch to 5w-30 here is the link:
Andrew, the internet is a great place. You can find whatever you want to support an argument no matter how ridiculous it might be. Just use the goddamn 5-30 and shut the hell up. Jeez!
I noticed you got alot of suggestions for 0-30 and 5-50 too. Now what are you going to do?

I run 5w20 Mobile 1 Synthetic. I get it at Walmart for like $36 for 6 quarts. Roughly $6 a quart. I think I might switch to Royal Purple, which is pretty much the same price. (Actually cheaper if you go onto a site like SummitRacing.com)

+1, there will always be people that are old school and think old school, there will always be people that are biased one way or another. And then there will always be people that think no matter what, they are always right! Best thing you can do is think logically, and then go with your heart.
By the way, if a ford service department is telling you to put in something different, i would get it in writting, from what i understand if you dont use the 5w20 and and something happens to your engine, well they can refuse warrenty work.

Don't come on hear asking advice and then argue about it when it is given honestly. You obviously have it in your mind that you need to use 5-30, so just do it. It's not the space shuttle or a nuclear reactor we're talking about, it's a Ford engine. Chances are very great that the car will be wrecked and/or worn out long before a difference in oil will be realized. " I only got 420,000 miles on this crap 5-20, I knew I should have listened to those guys, if I used 5-30 I coulda got 500,000."
One suggestion for 5-50 was since the topic did say that I drive it hard. My response to your post was because you posted this: Do you honestly think Ford would risk their reputation on just an oil viscosity ?? 5/20 is what's supossed to be used ! Everything else is just internet **** . ok bullcrap
Ford didn´t risk their reputation, they were just going for going for incentives.
Well, not all of us know Acura engineers and we just go with what is recommended. I'm a chemical engineer, but I suppose that doesn't carry the same weight around here as an ACURA engineer. Ask your Acura engineer what mod I should do next.

I just bought some Mobile 1 full synthetic today 5-20 at Autozone..!!!
as to the post.. the ONLY reason some say 5-20 over 5-30 is emissions ONLY.. trust me..
had a ENGINEER tell me this at a Acura school I went to a few years ago.. if anybody would know.. I think he would.. wouldn't you..???
Rex
WOW there is some serious **** being thrown around in this thread no wonder so many people get confuse. Go ask you ACURA Engineer to explain exactly what the Emission differences are between a 5w20 and a 5w30? Have him stick a tailpipe sniffer into the same car running both oils and see if there is a difference. He is full of crap. The weight of oil you run has absolutely NOTHING to do with Emissions.
And here is some info on CAFE. Trucks have been included for many years.

I use Redline 5w-20 every 5k miles. I've been a Redline fan for a long, long time. I was with the Redline 20w-50 gang. Bothered me to go to 5w-20, but I talked to Redline, and they said go with the 5w-20.
I've said it many times on this board, and others, look at www.tufoil.com If you want protection, it'll get the job done. Can I validate with something? Not really. But, 1) the machinest that built my engine for my "tweaked" BMW 320i recomended it over 130k miles ago. He said the only thing wrong with it was if he had to machine the engine again, it would be harder. He was a "BMW Engine Legend" here in San Francise Bay Area. 2) BMW you say? An old '78 320i, you gotta push that little 4 banger to make it sing, push it I do. 26 sets of tires on that car and counting, NO FREAKING WAY you can drive the GT that hard! Engine just sings!
I couldn't wait to get Tufoil in the GT. I talked to them also. They really like their product, said to wait at lead 5k miles before putting in. I waited till 4.6k miles. 8 ounces in the engine, and a 10% mix in the 5 speed trans with Redline D4.
Check it out for yourselves. Me? None of my cars or my cycle go without Tufoil. Redline for the cars, and Mobil 1 cycle specific for the Yamaha FJR1300ABS.

I was told by my motul dealer that the reason why most automanufacturers use 5w-20 is because it is less viscousity and gives higher mpg but at the cost of long term protection. I was recommended to switch to 5w-30. Anyone else has any imput on this?
Hi, You have a nice little mod list. I'm guessing that some of your work was done by a shop. I did my shocks, exhaust and the small stuff myself but I’m not an expert. Ford did my vortech install and I ended up in a lawsuit against them after I blew 2 engines. I ended up giving my car to an expensive but reputable tuner to go thru everything. As far as I’m concerned it isn't a Ford anymore it's his product. He made it work; I'm going to follow what he says. It's a judgment call on your part. He recommended 5-30W, that's what I'm putting in. I'm sure there is nothing wrong with 5-20. Just don't switch because your local store doesn't carry 5-20.
I will be amazed if my engine last 30K. I guess it depends how you drive, boost etc. If you drive hard and mod the crap out of your car, you’re probably not looking at riding your engine for 500K like the other gentleman is.

I recently put on a set of direct reading mechanical gauges. I use Pensoil Platnum 5w20 oil. That is a pure synthetic oil. When I start the car cold, my oil pressure hits 83 to 85 on a 70 degree morning. When the temperature drops a bit, I bet I see 95 + psi. With a heavier oil you will probably run a good chace of popping a oil filter. Most stock oil filters are good for @100 PSI. Stay with the 5w- 20 oil. These new engines are set up tight and a good freind of mine is a dispatcher in the service department and we have discussed this issue on oil and the differant weights. He even reccommended not going to a full synthetic until your engine has 8k to 10k miles on it to be sure it is broke in fully.
Wow, Are you seing this at idle? I'm reading no more than 62 to 65 when it's cold. At 12 psi of boost, my stuff is probably getting very loose inside. I'm not sure if the blower makes a difference with the oil pressure. Maybe that's why my tuner told me to go 5w30.

I was recommended to take redline 5w-20 as the only 5w-20 to put in my engine and If I wanted to go to 5w-30 that I should go to an amsoil since their 5w-30 has less viscoucity and that it is almost a 5w-20. All of the mods I have done with my neighbor because his dad is very into cars and installed a hydraulic lift in his garage. The only thing I didn´t do was the gear install. I Bought an oil temperature gage to see the temperature, If I see it runs hot with the 5w-20 I will switch to a 5w-30.
