so do i need to do a oil flush before changing back to honda geniune oil? or can i just go to honda and get an oil change like usual?
thx

 

But what you need to remember about oil, is that dirt sticks to it. Exhaust gasses blow past valve seals and rings (in minute amounts) every time a cylinder fires. It contains burnt hydrocarbons, and it blows into the crankcase where your oil is. The reason you have a filter isn't just for removing chunks of metal that could be there... it's supposed to also filter out the larger chunks of carbon that collects in the crankcase. The filter will eventually clog up with these if it's not changed.

I just remembered one of the guys in a band that's practicing in my house right now is an Amsoil dealer. I just asked him about the filter stuff. You're supposed to change the filter, but there's no guideline for when to do this with Amsoil, it's usually driver/owner preference depending on how dirty your car runs and what you put it through. He changes his every 8,000-10,000 miles (or 15,000 km if you prefer).

If you want to keep Amsoil in the crankcase, I'd start with just changing your filter.

If it still does this on a cold start after changing your filter, then check the oil sump. It's the pickup tube for the oil pump, and it has a screen in it that can get clogged by larger particles of? This is a more common problem on cars with timing chains because the plastic tensioner gets chewed up over time. It's not typical for a Honda to have this problem, but not impossible, either.

Someone else alluded to your oil's viscosity. Thicker grades of oil could possibly cause this in cold weather. You don't want that light coming on, and the healthier your oil system runs be it cold or hot, the longer your engine will last.

 

cuz i remember i just had an amsoil oil change with filter not very long ago, maybe 2 months ago, like 3000k on the oil.

how do i know if its the pressure problem?

thx

 

Well, you don't have an oil pressure gauge on it, and that would be the easiest way to tell. Maybe they put too thick of a grade of oil in it. I'd check your receipt if I were you, and possibly call the shop and ask them what weight they used (if they remember). Like I said earlier, why amsoil? Honda doesn't reccommend using it. I can't say that it harms anything, but I think amsoil is overkill for imports. I'd use it in 4X4's, but not in a 4 cylinder.

In order to check the sump, like I said earlier, you have to pull the oil pan. It's held on with 2 bolts, and you'll need a new gasket. You should be able to see crap clogging the screen in it if that's the problem. Clean it by soaking it in gasoline, then blow it out with compressed air.

ok thx!!

I actually found the problem happening 15-30mins after i shuts off the car, if its completely cold and left for couple hours or start it right after i shutted it off, its alrite, but if its after 15-30mins after i shutted it off, the light would come on once its started and goes off which its normal at this way, but then it comes back on for like a second then it would go off again. is this normal as well?

thx

 

The reason it blinks after letting it sit is because all the oil runs back down into the pan when you turn the car off, and that takes a while. Your oil pump must fill your engine all the way up to the squirters before you'll actually see that oil pressure light turn off... because the squirters act as resistors to build up oil pressure.

You don't want your engine running when that light is on. That's all I was meaning to say in this. When that light is on, the squirters aren't squirting. When there's no oil in on your bearing surface, you get metal-metal contact. That's when wear happens. Properly lubricated parts don't wear.

Roll with it. When it starts knocking loudly at startup, take it in for service. If that light starts coming on in any other condition, take it in for service.
