Hey!! What happened? Oh wellz, Yeah I got an oil change at this independent place and he put 10W40. When he poured it i was like whoa!!! Isnt that to thick there? And he said it should be ok
. Plus I went to a lot of places to ask for oil change and most of em said they wont be able to hoist it cuz my car is too low and i have a body kit. WTF!!!

WTF!!! hopefully you won't run into problems... i don't really know the difference... but my dealer keeps tellin to use only 5w-20... maybe its because they are one of the few places that sell it..

I know cuz, u only use thick oil when u have a lot a miles on ur car cuz the gaps between the piston and engine block is very close. So if u get thick oil it might not lubricate as well as the thinner oil which can penetrate through the thin gaps.

That is bad! Take it to somewhere else or you'll have a screwed up motor. If you want to live with it, you MUST warm up your car by letting it idle at least a few minutes. If it's cold out, you're screwed cause the oil will flow very slowly. There's a big difference between 5w20 and 10w40.

the second link that mclean987 posted seemed to be somewhat informative... but still don't know what to believe because they are trying to sell their product...
and kraziebonet41.... the Colts are gonna take it... lol

I live in seattle and I don't give a **** about the sea-chickens...
about oil, thicker oil can cause your engine to wear quicker... oil that is to thin can cause your engine to wear quicker... since you have such a heavy oil in there, you actually don't want your car to idle to warm up (this actually wears on the engine more than driving it, you want to drive it (it warms up faster when it has to burn more gas) just keep the rpms low, like 1000-2000, and then once it heats up you should probably be fine. The best thing to do is get on the freeway (JUST KEEP THE RPMS LOW) that way you're giving the engine more gas.
Most engine wear occurs when your car is being turned on, and when your car's oil is cold. Before multiweight oils, some engines would have oil in the oil pan that flowed about as well as peanut butter untill it warmed up.

First of all the only reason Honda recommends using 5w-20 is just for fuel economy purposes. Using a heavier oil will not harm the engine at all. How do I know this....I'm a salesman here at Country Club Honda in Yuma AZ. I spoke to Mike who works at the dearlership and is a Honda Certified Repair Specialist and since I always use 10w-30 oil on my 2k1 Civic he mentioned that "it really doesn't matter what oil is used" and as well what I just mentioned on the fuel economy. I noticed that when I used Mobil 10w30 oil w/Bosch Fuel Filter my engine actually runs smoother and cooler! Now aint' that somethin?

a 10w30 is much lighter than a 5w40. I do agree, the 5w20 is for fuel economy... and our cars are... economy... so I put in 5w20, also thicker oil will not flow as well in the cold , which will harm your engine. But, for most cases 5w30 or 10w30 is fine. I still like my 5w20

You guys ever pick up the auto mag that costcos provides for free?
The current issue, the one with the suzuki verona (aka korean market daewoo magnus) , has a little info about oil weights.
The lower the number before the W, the better for cold weather.
The higher the number after the W, the better it is for hot weather.
You're in hot south cali, 10W40 shouldnt be that bad if the article is correct.
Btw, after Jiffy Lube put 10W30, I had my first and only 300+ miles from a full tank of gas. Same hard driving as usual. It was very strange.

The question I would ask here is not so much about the fuel economy, but what is better for the performance of the engine. Is 10w30 allowing my engine to run better than 5w20? Of course this would depend on which area of the country you live in (ambient air temp) and the debate will go on for years about synthetic vs. petrolium based oils. Then there is also a difference in oil filters and getting a larger oil pan to hold more oil (cools the engine better for all you "hard drivers"). I think this is all going to boil down to personal preference and location/temperature.
Oh and I run Mobil1 10w30 with a K&N Perfomance Gold Filter. As soon as I can find a higher capacity oil pan, that is going on as well. I hate overheating

Sounds to me that your oil changer just didnt have any 5w-20 around, which is common for alot of places. Like some had said, its may affect cold flow which is not good thing for our tighter tolerance engines. When you use a thicker oil, the engine(especially the oil pump) has to work harder to circulate the oil. For me, since I can get Honda 5w-20 from my dealer, thats what I'll continue to use. If I wasnt able to get Honda 5w-20, I'd probably go with a good 5w-30 instead. 10w-40 just sounds to thick for me.

You guys that say that "thicker " oil is bad crack me up. For one what is "thick " oil? 10w-40 isn't "thick" oil, all it has is a heavier weight. Some of you make it sound like people are pouring molasses in thier engine. Even if you live in the snow belt of the country 10w-40 won't hurt anyhting. The "10w" on the bottle of oil means that the oil will not lose viscocity at -10° below 0°F. So even at 5° F the oil will flow properly.
The thing you need to look at isn't weight but viscosity, and 98% of brand name oil out there exceeds any minium tolerances required by engine manufacturers. 5w-20 is recommended because Honda engineers that spent years and years developing the engine to specific tolerances find that 5w-20 works the best for over all engine performance. A heavier weight oil will not hurt your engine, it will cut into your fuel milage, but thats it. You still have the same amount of protection that you would with 5w-20.
I would change the 40w oil out with 5w-20 or 5w-30 on your next oil change, just because thats whats recomended.

Soooooooooo..........5W40 is good enough? Reason I'm asking is I got a pretty good price on 4L of Motul 8100 5W40...and the bottles are just sitting in my room, and I'm about 100km away from my next oil change...

Oh and one other thing, why is it that thicker oil cuts fuel economy?

10w-40 is okay for your car but it isn't recommended by Honda. Honda wants you to use 5w-20 for the best performance the engine can deliver, 10w-40 isn't going to give the engine optium performance but it isn't going to destroy or harm the internals of the engine. Its like buying a printer, the company wants you to buy thier ink cartridges, even though generic ones work, its whats "recomended".
As far as fuel milage, 10w-40 is a heavier weight oil so it doesn't flow as well as a lighter weight oil would, so the engine works slightly harder (very slightly) but 10w-40 isn't so heavy as where its going to harm the engine. When I say doesn't "flow as well" I'm talking very very slight difference. If you buy a quart of 10w-40 and a quart of 5w-20 and rub a drop of each between your fingers you'll see both have very good lubricating properties, and that 40 weight oil really isn't that "thick".
This debate could go on and on, but I what I'm saying is that 10w-40 won't hurt your engine, but since Honda recommends 5w-20, I'd stick with that oil, after the next oil change.

This makes me wonder if the oil pressure differences are changed dramatically or just a small amount between 10w-40 and 5w-20. That and I think VTEC engagment in based off of oil pressure? I dont remember.. but maybe that has something to do with decreased fuel mileage for our cars.

Yeah, I think it all depends on the area u live in. For hotter areas its best to use thicker oil and colder places is better off thinner. Summer is over so i think having thick oil is not good.
