I was wondering if the weight of the oil should change with age?

I live in TX and it can get cold but usually not below the 20s. Last oil change was 5w-30 on an h23 but my friend said it should be heavier since teh cars old - 250k miles

 

this is a climate type question. its been discussed before. i leave 5w-30 in mine all year round. the manual that comes with the car even states it. you could go with 10w-30. whether is 5 or 10 once the car warms up, its all the same. the higher the number the thicker the oil. my car has age but i don't change the weight. maybe the type of oil but not the weight.

 

If the car doesn't burn any oil, stick with the 5W-30.

If the car burns oil profusely, use 10W-40.

 

i heard that 0W 20 is the way to go. But I dont know my self. If you go to mugen website mugen-power.com they sell 0W 20 for all/ most of the cars they offer parts for. So i was strongly thinking to switch over, but i would like to hear people opinion before i mess something up.

 

once the oil is heated up, the cold weight won't affect a damn thing, so if you have leaks then a 5 cold or a 10 cold would help, but if not, get a 0w-xx, 0w-20 or 0w-30, and remember, a better quality oil will protect better then a cheaper oil, i like amsoil

 

I like the Shell Rotella 15W40 in my old stuff.

 

they make rotella in synthetic now, so you can get it without the stupid high weight

but again, amsoil HDD in my opinion is mo betta

 

Absolutely not. Especially with an H-series engine, a notorious oil burner. All you'll be doing is literally vaporizing money into thin air.

As I said above: 5W-30 viscosity if the car doesn't burn much oil, and 10W-40 if it does.

 

There is some truth to that.

But you probably don't want to hazard a guess, use oil pressure as a guide if you want to mess around with things.

 

i stand corrected. i was looking thru the helms the other day and it actually used 10w-30 from 0 degrees to 100+ and 5W-30 was from something like -15 degrees to 40-50 degrees. but still either way, once its at running tempeture, doesn't mean much. but if your motor is burning oil like most h22 due to vtec then a thicker oil could help.
