Look at this site I found regarding the oil we use for our cars.oil site

[IMG]i/expressions/face-icon-small-mad.gif[/IMG] bastards! hey civicdude, so what would be the ideal oil to use for our cars? my last oil change was 5W-30

Hmm, why are they so concerned about this issue, for our protection? or do they have some stake in the discussion? Why yes they do! they are trying to scare you, and make you buy their product.

I'm sure there is no harm in using 5w30, and yes it may provide better protection but there is a corresponding increase in the amount of internal friction between engine parts, thereby dropping mpgs and performance. You simply can't have it both ways, it's a tradeoff.

So if I put 5w30 in my car, it wont damage it? I hate to have togo back to the dealer everytime for an oil change? What does everyone put in there car? I am supposed to be at the dealer tommorow morning at 7am for an oil change. I have to go this time because my idle is shaking really bad, and I want to get my clutch pedal creaking fixed.

I go to the dealer as well, will Honda put 5w30 in if you ask them too?? Will this really affect the everyday driver using 5w20?? Thanks for your responses, enquiring minds want to know!!

They wont put 5w30 in because the car is supposed to get 5w20 according to the owners manual.

Hey all! i put 5w20 just like it calls for! i can find it at kragen and also at walmart. i'm sure there's a reason why honda put 5w20, and i don't think it was to **** us all off. [IMG]i/expressions/face-icon-small-smile.gif[/IMG] so, call around to walmart and kragen, perhaps sams club....

Yeah I'm kinda weary about that article! I mean It does in a way make sense, but they are totally bias on there oil. I have been wanting to put Mobil 1 syn. In My car but they never released a 5w-20 oil. Does anyone use Mobil 1 and does it make any much more of a diff?

a lot of dealers will put in 5-30w because they are using it for all the oil changes they are doing. they buy oil in large drums and use a gun to fill the engine. they also might be using a brand other than honda, some places will even have a castrol sign or another brand hanging out somewhere.

Hmm, looks like Ford did something to **** off Amsoil [IMG]i/expressions/face-icon-small-smile.gif[/IMG]. The Amsoil article does have a valid point - 5w-20 oil isn't absolutely necessary for your car and our Civic will run fine on any SAE 30 motor oil.

However, I do find it ironic that Amsoil says:

"Don't use 5w-20 oil because it is worse for your engine, use 5w-30 oil instead."

BUT

At the conclusion of the article they try to pimp their 0w-30 motor oil!

As one of the leading manufacturers of synthetic motor oil, Amsoil knows very well that motor oils with a wider viscosity range (e.g. 0w-30 has a much wider range than 5w-30 or 10w-30) contain more polymer additives. More polymer additives generally lead to increased viscosity and thermal breakdown in your engine. As a rule of thumb, you should always use the narrowest viscosity range that suits your needs, because motor oils with higher viscosity ranges (like 0w-30) need more polymer additives to do the job.

For example, in southeast Texas, where it hardly ever snows and only drops below 40 degrees for a few weeks during the year, 10w-30 and 5w-30 both work fine. In fact, several of my friends use 10w-30 during the summer and 5w-30 during the winter.

Just keep in mind to be careful of any 'news bulletin' created by a motor oil manufacturer that has a vested interest in pimping their products for more $$.

hmm...do they make 5w20?? no they missed the boat and are trying to make up for it through words. 5W20 is better because that is what the engine was built and tested with, and the closer the two numbers the better because larger ranges (5W40 for instance) has a lot of viscosity improvers in it which are not very good lubricants.......

You're on the right track, but just a minor correction - a motor oil like 5w-40 not only has a greater viscosity range than 5w-30, it is a totally different oil altogether (it is viscosity 40 as opposed to 30). The reason against using 5w-40 in our cars should be that viscosity 40 is too high for our engines, not that 5w-40 has a greater range in viscosity than 5w-30.

sounds like an oil Amsoil add to me

Yep, htowncivicEX is right. It's basically AMSOIL's attempt to make you buy more 5W-30 motor oil. They probably didn't get that contract to sell the 5W-20 motor oil and they're losing money, so they thought up this little article. It's cute 'cause everything they say is the truth. They just state it in a funny way to make it sound like 5W-20 motor oil is bad for your engine. [IMG]i/expressions/laugh2.gif[/IMG]

The ony thing about thicker viscosity is that it sticks to all the engine parts and protects a little better. However, our oil protects the engine just fine and the lower viscosity means less friction, and less friction means more horsepower! That's right.

Don't believe it.



<< Do I really need to use 5W-20 oil and why did my 2000 model year vehicle require a 5W-30 oil, while the exact same engine in my 2001 model year requires a 5W-20 oil? >>

Um.. NO it's NOT THE SAME ENGINE!! That's why!

Be careful about stuff like this. Oh yeah, like Honda will purposely hurt their reputation by making your engine not last as long. There's no good reason for them to do that. The reason why Honda sell so well is because of the reputation for reliable products. It's the only thing they have.

You know, the most important part of Honda's business are engines. In fact, I've heard things like 'Honda doesn't sell cars, just boxes to put their engines into". If you don't believe the people that design and engineered your car, who else ar eyou going to believe? Joe Schoe and his faulty logic?

I'm not saying that 5w-30 will destroy your engine, but neither is putting 5w-20. And the engine was designed to use 5w-20.


GENERAL RULE:

If you follow the owners manual word for word and things break... you can still complain. If you do stuff against what the manual specificly says you can't do, you can't complain. They'll just say "we told you so, you idiot!"

I USe 5W30 Synthetic anyways [IMG]i/expressions/face-icon-small-smile.gif[/IMG].. Petroleum oils with wide viscosity ratings have the additives galore problem.. Synthetic oils area whole different ball game. ALso.. Say you live in LA or Texas..or somewhere always hot.. then during the summer it'sperfectly safe to use straight 30 weight oil. In the winter when it cools off a big you can use 10W30. a 10W oil still remain highly viscous down to about 40 degrees..before the viscosity differences actualy become noticable.. I'm waiting though for someone to start producing 20 weight Synthetic oils tho..

the reason why Honda wants us to use 5w20 is that the clearances in the motor (between piston rings and cylinder walls , between crack bearings etc.) are alot smaller now they need a thinner oil
that is also why they can say to change your oil every 10k miles as opposed to every 7500 miles the oil doesn't get contaminated with fuel as muh now hope this makes sense of course 5 w30 won't hurt yor engine but neither will 5w20

I agree with the 5w-20... 5w-30 can't handle cold weather when starting.

But changing your oil at 10k... I don't care if it's a Honda, do it at 5k. My car slowed down badly after 5,000. Meaning the engine was having a harder time doing it's job. I mean, perhaps it's okay, but it doesn't do good on the side of performance. And I would also think that in the long run, your car won't last as long because of the strain you'd put on your car from the needed oil change when it's evidently evident.

Amsoil does make a 5W20 syn.... So whats the deal ? [IMG]i/expressions/face-icon-small-confused.gif[/IMG] I really think Honda and Ford are driving us alittle crazy... (And this article does bring up some good points) Why doesn't Toyota, Nissan, GM and others call for this 5W20 ? All I know, when its 97 degree's here in Tampa in stop & go traffic.. I'm glad I'm using 5W30 !

great article man, what an informative read.....kinda like marlboro telling you not to smoke winston's because they contain higher levels of tar and will kill you faster?????.....what the f**K!! how can you take a supposed un-baised article seriousley when buddy is trying to sell you something specific at the end.....he'll even sell you 5w 20, the "bad" oil, but, his brand is different, yeah, right....pls inform us of articles that are actually helpfull.........

Maybe I'll just take a drive over to Amsoil myself and ask them. Their HQ is right across the bridge from Duluth. Interesting article.

Honda is the largest engine manufacturer in the world. They won't steer you too wrong. Take those kinds of pseudo-informative articles with a grain of salt.
