At this point the best GM can do is take a loss every for every sale they deny to Tesla

Not being able to do the pump ability test doesn't mean mean I don't know what it is. Try another strawman. Have a link to pump ability tests of used oil compared to new oil? Seems like you would have lead with that if you did.

Its so simple even you can do it. Take a fresh quart of oil and a used quart of the same oil, put both in a freezer and see how much thicker the used oil is. You'll see the used oil is significantly thicker.

Yeah if its only going to get changed once a year i say do it right before it gets cold. One of the first thing oil seems to lose is its cold pumping abilities. I'd rather run fresh 5w then a burned up year old 0w.

Staying thinner than 6,000cP is all you need. Most 5w oils are getting pretty close to 6,000cP at -20f.

Yeah 4,000 miles of driving to work, going to the hardware store, towing no further than the next town over Vs. 4,000 miles with 1,200 miles of road trips was a huge difference.

I did not know that 40% of the GTL was offline. Once GTL comes back online, as natural gas prices are still low and crude oil goes back down; im sure they'll roll back the oil to within a few dollars of where it was. Baring worldwar 11 or any other major theater accounting errors.

Eh, I used to pay $35 to nearly $40 for Pennzoil Ultra Platinum before Walmart started carrying it.

I wouldn't worry about that 18psi. That's 18psi after the filter. I've seen plenty of diesel oil filters that run 20 to 36psi bypass. If that pump needs to make 30 or 40psi to push the oil through a partially clogged oil filter to make 18psi at the pressure sensor, it will.

On my wifes car I found that I couldn't go anywhere near the recommended oci of 7,500mi according to test results. I couldn't use better oil like amsoil or hpl due to fuel dilution. I could but I would be wasting it. Just her driving the car it needed 3,000 to 4,500 mile oil changes due to fuel...

My observation is Valvoline Restore and Protect seemed like it was barely doing anything until I took it on multiple road trips that involved some towing. Then I saw a dramatic increase in filter sludge.

My Honda piston in that pic had hundreds of hours on it and didn't have an easy life. The only break it got was the guy who used it for the 15 years before I had it I bet he changed the oil at least a dozen times on it, probably closer to 20 times. Only reason that Honda went bad was one of the...

Yeah. Run the engines, take them apart, look at the pistons.

Those "20 micron full flow oil filters" are actually pretty good at stopping particles down to the 1 and 2 micron range. Those bypass filters really don't do anything especially when you change your oil somewhat on time. I say if an engine is known to burn oil or needs 2,500mile oci to not...

Form what ive seen the main mechanism is neglect. You say it's the engines patman says it the oil. Which is it? I asked which oils and never got an answer, I and I'm sure many others would probably like to know what oils to avoid.
