So that made me check my oil pressure, it was a little low at idle so I moved up a grade and never looked back. That was when my car had around 45k miles, my wear numbers are now under avg. the TBN shows I could run my oil longer and sometimes I do. Now that they changed the damn oil again because of CAFE I am going to have to find out if the new CAFE will change A/W and F/M in these H/M oils.

The OP has 12 to 20 psi at idle, how low would you let it go before you moved up a grade of oil? Or would you just take the car off the street and rebuild it? I've had a car that I ran striaght 40w because the bearings were so loose but the 40w gave enough boundary layer strengh that that '61 Dodge made it through 3 1/2 years of college.

I just changed my oil so I have a few months to find out if the new CAFE standards change the 10/40 HM oils or not. If they did, then I'll go with a oil that is not under the governments thumb and has the A/W and F/M that will protect my Honda. And if I do have to change oil's I will check with a uoa to see if its doing what I what it to do and that is to keep wear numbers low.

To the OP I would still take off your oil filter and cut it open to see what there, if you don't have a bunch of small, medium to large flakes I'd just move up to a 10/40HM oil and see what your oil pressure is at NOT.

I do plan on cutting my oil filter open on my next oil change when I switch to 10W-40. I'll also be going back to the OEM filter, currently using a mobile1 filter. I put a magnetic drain plug in and the last time I changed it I found no metal on the plug, not sure if that's a good thing or not but I thought I would share. Thanks for the help guys, I'll keep you posted.

Once the snow is gone and the salt off the roads so I can get my car out of the storage barn and in my garage I'll be changing the engine oil, transmission oil and dif oil to fresh Amsoil. I am anxious to see if it has any noticeable impact on the transmission function. I doubt it. But, we shall see.

BTW, i didn't see if mentioned anywhere in the thread, but you are measuring your oil pressure from the OEM spot, correct?

Yes, I removed the "dummy" light and installed a aem pressure sensor with a BSP to NPT adapter

So quick update everyone!!

I changed my oil last night to AMSOIL 10W-40 with a new OEM filter!


As for the night of driving here are my new Oil pressure numbers

Cold start Idle = 98+ psi
Normal Temp Idle = 16-18 psi
Above 3K = 82-94 psi

I also pulled apart my Mobile 1 oil filter, here are the pictures from the cardboard spread out. Let me know if I should be concerned.

Filter looks good, if you had bearings going south you would see a LOT of it in the filter. Same goes for rings, piston skirts or cylinder walls, cams and rockers too. They would all end up in the filter.

I mean I wouldn't say it worked 100% but it's better. It definitely didn't raise it to the 36 psi spec but I guess it's better.
