hey guys...
just an opinion...
i have an accord 95 that ussually run at about 100-130KPHon general driving daily...
and just wondering what is the best oil grade/temp for this kind of driving?
or it doesn't matter at all?

thanx

 

Where are you from, how low does the temp get?

 

perth australia
in winter temp can get 10 to 25 deg
in summer it can go from 20 to 45 deg

 

5W-30, per my owner's manual. Have been using it since day1, in a temperature range not that much different from yours. I use Mobil1 and have been replacing oil &filter every 5,000 miles (that's ~8,000 Kilometers).Doesn't burn a drop of oil and never have had any oil leaks or related lubrication problems.

 

its kinna hard to find 5w-30 here though... will it make a big difference if i use 10w-30

 

You have to be using Celcius degrees:

10-25 C = 50-75 F

25-40 C = 70-110 F

If I am right, then 10w30 will be fine. You should use 5w-30 if the temperature gets to -5 C (<20 F)

 

I have always used 10w30. I live in Mississippi where it rarely evergets below 0 Celcius or 32 F.
10w30should be just fine for you

 

10-25 C = 50-77 F
25-40 C = 77-104 F

So that's correct, 10w-30 should be fine.

Once the enginegets to operating temperature, 5w-30 and 10w-30 are supposed to be the same. The "w" number is how the oil behaves at about 0°C & the number without the w is how the oil behaves at 100°C.
