What oil is better for a 130k miles car engine?

I have a '97 Civic, with 130,000 miles. The manual recommends a 5W-20 oil, but my car is 12 years old, and with many miles on it, and I wonder if I should use the same type of oil, or if it is better for the engine to use a heavier oil, like 5W-30, or other type of oil, and if so, which one is better?





Thanks in advance for your advice,What oil is better for a 130k miles car engine?
Stick with the recommended oil. The only reason to change is if you notice your car is using more oil or if the oil pressure light is coming on occasionally indicating a drop in oil pressure that could be from worn engine parts.





Thicker is Better Myth


The reason that oil viscosities have gotten thinner is because bearing clearances have become smaller. Using thicker oils will interfere with oil flow and the oil pressure will increase. In a worn engine it may be okay to increase the viscosity of the oil because the bearing clearances have become larger.





In fact I use Mobil 1 0W30 in my '96 Accord even though 5W30 is recommended in the owner's manual and since switching to it I do notice an increase in fuel economy.





If you really want to know what is best then get your oil analyzed and see what the lab recommends. http://youroil.net/single_sample_kit.htm鈥?/a>What oil is better for a 130k miles car engine?
If your engine is still in good shape, don't change. The only change I would recommend is to synthetic oil. Stay with the 5w20 as recommended by the engine maker. That engine is engineered to operate with that viscosity and will not be as efficient with a thicker oil.
call a local honda dealer and ask their opinion.


use 5-20w. don't switch if the engine is fine.


also, if its used synthetic, get a synthetic 5-20w for high mileage cars (ie, castrol)


but if honda says no synthetic, don't switch now, the engine is too used to normal oil.
i would use a little heavier oil specially in the summer. a heavier oil won,t break down so fast in the heat. my car has 129,000 miles and i use high mileage oil. myself i use 10w30 year round. i just got done changing my oil.
Good question. You could go with a heavier oil without hurting the engine. But if you would like the same fuel economy i would stick with the 5w20.
If it were mine Id use 5-30 or even 10-30 especially if your in a warm climate. If you got 130k out of the car with 5-20, why switch?
Always stay with the recommended oil. If you bought the car new... stay with same brand.
use high milage oil valvoline makes one. as for the weight it makes a diffrence on your climate.
