My 2006 Civic never takes long to warm up, even in the winter. I believe all cars need to warm quickly for the emissions. I will check but I think it is up to temp in maybe 2 miles. Though my UOA's don't show unusual lost of viscosity.

down to 5%

That is what I did, tried a few times no change.

I know Mobil1. What's wrong with my image link?

It seems a new air filter (Purolator classic) really does filter better than an older one (OEM). Interesting how close the Mobile1 and Ultra compare with equal miles. Had an oil change between these two, that is when the air filter was changed. The filter was M1 second OCI, but drained it in...

I would put a screw driver in there to see if it it can be knocked loose or to judge if it has a strong bond. If it comes loose I would return the filter as defective, or try to get it all out. It is on the clean side of the media and if it comes loose, no telling where it will end up or what it...

I have always drained the oil out of used filters. I have been cutting the filters open and usually save the metal for the scrape dealer. The media, gasket and ADBV go in the trash. Before this, I would take them to an auto service business that would take filters and crush them. I have been...

Does anyone know the expansion difference for oil cold to hot? I imagine to main difference for Toyota (side mounted filter) is if the oil filter anti-drain-back is holding oil back over the cool down period. It is also possible the oil pickup to filter passage, over enough time, may drain...

For comparison my Civic at 82k, 8.1k OCI had Si at 21 with paper filter, Al 11 and Fe 12. I would do one more UOA to confirm any trend, before deviating form Honda's recommendations on oil.

Why would GM put this pattern where oil needs to drain??? Designed to trap crud.

Collapsed filter IMO is failure and next could be torn media. The loss of vertical structure means the end contact seal could be bypassing, depending on the mounting. If it was synthetic media it would not absorb moisture and expand. I assume no internal support or mesh backed media. Apparently...

I would have said they may be reducing the number of offering after looking at; epc.shell.com Class >> Shell lubricants >> Automotive >> Engine Oils - PCMO Given Ultra appeared to be their primary GTL product (NA market) maybe its cost is too high or a price increase to WM didn't fly. Why...

The PU 5W20, 5W30, and 10W30 are the only ones that call out GLT base oil in the MSDS's. "Fischer-Tropsch derived base oil, consisting largely of branched, cyclic and linear hydrocarbons having carbon numbers in the range of C18 to C50." These are also the same grades that are on clearance at...

I believe the dent is just evidence of a fairly high drop on the end of the filter. The weight of the filter element hitting the against the leaf spring is what fatigued, deformed, or stretched the leaf spring so it no longer was providing the necessary pressure to hold the element tight. A coil...

The engine results section seems weak. The cam bearings and lobes look to have signs of scoring to me. Just one vehicle analyzed, no complete tear-down, visual (subjective) analysis instead of measurements. Could have done UOA and pulled all value covers and oil pans. Apparently a low budget study.

The cartridge filters I have used have had near perfect pleat spacing no matter the brand. Purolator and other canisters have poor workmanship because so few are every opened up to be inspected. With this quality and lower filtration (40 micron) I have bought my last P1.

With the various pics posted recently, looks like varnish can attach to different degrees on specific parts. I suspect different Aluminum parts have different metal treatment. In the above case the valve train parts versus the head and cover casing, day and night difference. The one rocker just...
