Sup guys
I had a post up here before and I asked you guys what oil I should use. And most you guys told me to stick to what Honda told me. Well I been arguing with my cousin with his honda because he read this article
http://bestsyntheticoil.com/amsoil/5w20-cafe.shtml

and according to the article the recommendation to use 5w20 oil just a way for Honda to make money?? That sounds kinda fishy and not true.

it's beneficial for everyone I think.

Honda gets their cafe ratings, you get your better gas milage + slightly better acceleration.

everything is good ;P

At least I use synthetic oil...

Reread the first fw lines agian... they state that the SAME engine that used to use 5w30 is now using 5w20... Honda had a new civic engine when they said to use 5w20, never has the D17 used 5w30. That statement tells me that they are directed at Ford, because Ford did exactly that, did not change the engine, just the oil. Not that it matters much, I really don't think the difference between 5w20 and 5w30 is going to do anything. They claim it will not protect as well and this and that, and that is only true once the addatives have been depleted, and if you drive your car/truck that long you are going to have problems no matter what. They are taking a obscure facts and blowing up making them look like it's a big deal, and it really isn't.

In short, I use 5w20 in my Honda and Ford, just because I have no real reason not to. If you want to use 5w30, you won't kill your engine or anything. use 15w50 and your engine WILL blow up.

if the car is really intended for 5w20 then you should use that oil. there isnt much difference between 5w30 and 5w20 its that 5w20 is thinner oil and used in different climates. at my work we sometimes put 5w30 in 5w20 cars and its no big deal. just like wat jrfish007 said u can use 5w30 in your car and it wont do any sort of damage just dont use 10w30 or any thicker oil.

5w20 is better for the engine because it lubricates better and gives higher gas mileage. the engine has very small tolerances compared to previous years.

Would using a 5-30 Synthecic be better.

 
Rep Power: 813

its too thick especially in a cold climate

 
Rep Power: 320

well.... yes and no. the synthetic part has nothing to do with it though.

5w20 is best for a new engine. After a while, say somewhere around 50-75k miles, the tolerance have worn a little on your engine and the clearances have became greater, so a slightly heavier oil is probably just fine. I would say using a 5w30 or 5w20 will be fine after a couple of clicks on the odometer.

i use amsoil 0w-30 and i've gotten a performance gain (very noticeable) and i get up to 35,000 miles before a change...but i usually go 25-30k before a change... with a filterchange at 10,000

Have you had this oil tested yet?

You really should change your oil on reccomended intervals per your owners manual or sooner. If you have a oil related engine problem you will have voided your warranty. Of course with only 36,000 mile warranty it may not matter. Just my .02 cents worth. I myself would never push a regular oil past 5000 miles and would only consider going 10,000 on synthetic with a filter change any time I change my oil.

If you are worried about warranty then stick with 5w-20, if not knock yourself out with whatever weight you want. The same engine in places like Singapore, Europe, and Australia has viscosities as high as 15w-40.

I live in the U.S.A.

My point is that they recommend viscosities way higher than a 20 weight outside of the US for basically the same car. But as I stated before, if warranty is your concern then stick with 5w-20.

Your owners manual says 5W-20, the oil cap in your engine says 5W-20. Use 5W-20, it isnt that hard to figure this out.

5w-30 is good in the summer time when its like 70-80 degrees, but in the winter it is to thick. I remember because last summer, when i had in 5W-20 and it was extrememly hot and i was reving and driving hard like i normally do, i could feel the engine not running as smooth, i switched to 5W-30 in the summer and it felt better, but then i kept it in when it started getting colder and it felt worse, so i switched back to 5W-20 and it was good.

even the noob knows how to read and understand. its not that hard to figure out with all the clues honda left.

I am not exactly sure why Honda uses different oil vicosities for other countries but one this is that alot of European countries have a lot higher speed limits on their roads than the good ole USA. Another thing could be the C.A.F.E. limits that we have here that penalize any manufacturer for exceeding the fleet gas mileage. Then again maybe Americans are more prone to change their oil when it is recomended compared to other countries, I do not know, but my main comment before was that I think you should try as much as possible to change your oil on recommended intervals (or sooner) and use the recomended oil in your engine since this is the cheapest thing you can do to prolong engine life.

5w-20 is good oil weight, especially in colder temps.. it helps the oil circulate easier during start up and gives lesss friction on the engine, the down side is, in hot areas and extreme driving conditions, 5w-20 tends to be to thin to protect... what i did the other day was change with 5w-20 then i added a little bit of 10w-40 (less then a half of a quart), and it was thicker, but not as thick as 5w-30

For the D17, the manual even suggests using a tad thicker oil in solder climates. The R18 on the other hand says to ONLY use 5w20.

The owner manual says you can use 5W30 in case the 5W20 isn't available or in hot climate. Read it.

And about the article I disagree with it; if your owner's manuals says what type of oil the engine have to use you have to use that type of oil. You can't change other oil type because you think or someone told you to use anotherone and expect the manufacturer cover a warranty of a failure.

Even a service station (ex. a quik lube) have to add to your engine the oil specified for the manufacturer and the quantity the manufacturer spec...

Example, the chrysler crossfire have specs to use "Mobil 1 0W40" (or something), you can't add other type of oil because the clearances...

Notice I said my R18, that is the engine code for the '06+ civic's, I don't have a 7thgencivic any more (gave to my dad). The 7thgen civic's (2001-2005) could use a wide range of oils according to the manual, the 2006+ says to use only 5w20 no matter the climate.

jeebus ... it's right there on the frickin oil cap! ... why wouldn't you use it??

you may have "perceived" a gain, but you really didn't gain anything.

contrary to popular belief, the kind of oil you use will have pretty much zero effect on your mileage or the performance of your car. anything that is a decent oil and a proper weight for your car will have the same effect.

all you perceived was your own cognitive dissonance.


also, have fun shortening the life of your engine by going 25,000+ miles between changes.
