I always used 5w in my car, i went to auto zone last week, and they didn't have any, i asked the guy for assistance he said what car you have i told him 99 em1, he started literally bitching at me, for not using 10w-30, i told him i wanted the 5w because its thinner, and i prefer that, and he is all like what do you feed little babies and ****, here use the 10w-30

I noticed the car don't bahave the same with the different oil, anyone else have similar experiences

i use 5w-30, never used 10w-30

5w30 runs though your engine quicker.

boostsohfast

I use 5w when its really cold like over the winters.... I use 10w over the summer.

vtecb20coupe

i use 10w-30 for a car with more miles. honda uses 5w-30 on most of their cars.

that idiot was like your car has only 50K miles, you don't give hamburger to a baby, use 10w. I used it because they had no 5w, i think i'm switching again to 5w

AutoXer

I have a 00 EX, and the manual specifies both 5W and 10W, but according to the service manual, previous models with the same engine were specified as 10W, I'm assuming that's because 5W wasn't readily available. Same engine, different specifications for oil.

Now the newer models are specifying 5W-20 and 5W-30, but I'm not certain if the 7th gen 1.6L are the same internals / clearences as the 6th gen. If they are, the oil switch is a matter of efficiency, nothing more. The thinner oil causes less internal friction, and more milage.

To answer your question though, it depends on where you live as well. I run 10W in mine, and switch to 5W in the winter (it gets cold in the northeast.) Jackson Racing uses 10W-30 year round on all their cars, new and older, but in california, it's not much of a concern. I'd use the heaviest oil specified (wich is 10W for your car I beleive) for the greatest viscosity protection. Thinner oil, while more efficient, can offer less protection depending on the tolerences of your engine. If the tolerences are large, or the engine is high milage, a thinner oil than what's specified won't offer the protection you need.

I've always heard use 5w30 for the winter and 10w30 for the summer. I'm using 5w right now.

So you're saying to stick with 10w.
Although the factory specs says to put 5w-30 for the em1 it even says that on my oil cap.

sohcvtec1995

i use 10w. But it really depends on what kind of driving conditions the motor is going to be handling.

wilsel

I switched to 5W, better protection in colder weather, and the same protection when hot. The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature. 5W makes the engine feel smoother, and gives better gas mileage from my experience.

Never ever ever take advice from an Autozone employee or employee of most any other chain parts store. You know who those people are? Community College drop outs. They couldn't make it as a real tech and ended up there. Worst part is that they think they know what they're talking about. I've heard some of the most amazing crap come out of their mouths. Just nod politely and ignore their advice. They're 90% salespeople, 5% mechanics, 5% something else.

Electron Si

I've been using nothing but 10W-30 in my Si. Says to use 5W-30, but having a higher viscoscity when cold is important for coating the engine with oil, especially when you start getting higher miles. 10W-30 Castrol Syntec =

Can you explain why it would be better to have a thicker (higher viscoscity) oil when the engine is cold, a lighter oil will flow better, and lube parts faster.. Please explain..

words of wisdom

Two_K Si

Since you live in texas, 10w-30 would be better. a 10w30 will resist shearing down compared to a 5w-30. I personally use a 5w40 and 10w40 in my Si and i live in So Cal so it dosnt get very cold.

yea.. i believe honda manual says use 5w in cooler climate and 10w in warmer ones

way too think imo... just 'cuz its used in vettes, it doesnt mean that it'll work well in you honduh.

i personally use 10w30 mobil 1. it never dips below 40degrees here where i live.

ejprimo

lets say that i live in germany and i owned a b16a civic.

according to the manual they wouldnt allow the use of a 5w-30 unless the temperature got below 0C.

Grimm

10W30 my oil light sometimes comes on when it's really cold out when starting the car, but I let it warm up before going anywhere...

next time 5w30 for winters

It true.. I use 10w30 on B18c5 motor because the oil wont burn faster.. I used to have 5w30 and it burn the oil faster.. I just give opinion to u...

wilsel

That graph is showing you the temp range for each oil, 5w 30 provided the same protection as 10W 30 and then some (more when engine is cold). Think about it. Your engine sits overnight, oil has dripped from most parts into the pan. Do you want syrup to go thru your oil passages or something not so thick? Once the engine is at operating temp both oils are 30 weight. Just an analogy, I want something that's lighter weight no matter what the temperature. Because it gets to the parts faster.
